  1. 3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA and partners from Aerostar and AeroVironment discuss a simulation of a high-altitude air traffic management system for vehicles flying 60,000 feet and above in the Airspace Operations Lab (AOL) at NASA’s Ames Research Center in California’s Silicon Valley.NASA/Don Richey NASA, in partnership with AeroVironment and Aerostar, recently demonstrated a first-of-its-kind air traffic management concept that could pave the way for aircraft to safely operate at higher altitudes. This work seeks to open the door for increased internet coverage, improved disaster response, expanded scientific missions, and even supersonic flight. The concept is referred to as an Upper-Class E traffic management, or ETM. There is currently no traffic management system or set of regulations in place for aircraft operating 60,000 feet and above. There hasn’t been a need for a robust traffic management system in this airspace until recently. That’s because commercial aircraft couldn’t function at such high altitudes due to engine constraints. However, recent advancements in aircraft design, power, and propulsion systems are making it possible for high altitude long endurance vehicles — such as balloons, airships, and solar aircraft — to coast miles above our heads, providing radio relay for disaster response, collecting atmospheric data, and more. But before these aircraft can regularly take to the skies, operators must find a way to manage their operations without overburdening air traffic infrastructure and personnel. NASA partners from Aerostar and AeroVironment discuss a simulation of the ATM-X E Traffic Management (ETM) system for vehicles flying 60,000 feet and above in the Airspace Operations Lab (AOL) at NASA’s Ames Research Center in California’s Silicon Valley. “We are working to safely expand high-altitude missions far beyond what is currently possible,” said Kenneth Freeman, a subproject manager for this effort at NASA’s Ames Research Center in California’s Silicon Valley. “With routine, remotely piloted high-altitude operations, we have the opportunity to improve our understanding of the planet through more detailed tracking of climate change, provide internet coverage in underserved areas, advance supersonic flight research, and more.” Current high-altitude traffic management is processed manually and on a case-by-case basis. Operators must contact air traffic control to gain access to a portion of the Class E airspace. During these operations, no other aircraft can enter this high-altitude airspace. This method will not accommodate the growing demand for high-altitude missions, according to NASA researchers. To address this challenge, NASA and its partners have developed an ETM traffic management system that allows aircraft to autonomously share location and flight plans, enabling aircraft to stay safely separated. During the recent traffic management simulation in the Airspace Operations Laboratory at Ames, data from multiple air vehicles was displayed across dozens of traffic control monitors and shared with partner computers off site. This included aircraft location, health, flight plans and more. Researchers studied interactions between a slow fixed-wing vehicle from AeroVironment and a high-altitude balloon from Aerostar operating at stratospheric heights. Each aircraft, connected to the ETM traffic management system for high altitude, shared location and flight plans with surrounding aircraft. This digital information sharing allowed Aerostar and AeroVironment high-altitude vehicle operators to coordinate and deconflict with each other in the same simulated airspace, without having to gain approval from air traffic control. Because of this, aircraft operators were able to achieve their objectives, including wireless communication relay. This simulation represents the first time a traffic management system was able to safely manage a diverse set of high-altitude aircraft operations in the same simulated airspace. Next, NASA researchers will work with partners to further validate this system through a variety of real flight tests with high-altitude aircraft in a shared airspace. The Upper-Class E traffic management concept was developed in coordination with the Federal Aviation Administration and high-altitude platform industry partners, under NASA’s National Airspace System Exploratory Concepts and Technologies subproject led out of Ames.

  2. The fifth anniversary of the first all-female spacewalk by NASA astronauts Christina H. Koch and Jessica U. Meir seems like a good time to tell the story of women spacewalkers. Since the first woman stepped outside a spacecraft in 1984, 23 women from four nationalities have participated in 61 spacewalks. These women made significant contributions to their national and international programs, conducting pioneering work during their spacewalks. Their accomplishments include servicing of satellites, assembly and maintenance of space stations, conducting research, and testing new spacesuits. Since the first spacewalk performed by a woman in 1984, women have displayed their contributions in performing extravehicular activities and there has even been four all women spacewalks since then. Table listing women with spacewalk experience. As of Oct. 18, 2024, 79 women have flown in space, and 23 of them have donned spacesuits of different designs and stepped outside the relative comfort of their spacecraft to work in the harsh environment of open space. The various spacesuits, Russian Orlan, American Extravehicular Mobility Unit, Chinese Feitian-2, and SpaceX’s new design, all provide protection from the harsh environment, essentially turning the astronauts into individual spaceships. They all provide the crew members with the ability to carry out complicated tasks in open space. Left: Soviet cosmonaut Svetlana Y. Savitskaya during her historic spacewalk outside the Salyut 7 space station. Middle: NASA astronaut Kathryn D. Sullivan during her historic spacewalk during STS-41G. Right: NASA astronaut Kathryn C. Thornton on her second spacewalk on STS-61. Soviet cosmonaut Svetlana Y. Savitskaya made history on July 17, 1984, as the first woman to make a second trip into space, on her second visit to the Salyut 7 space station. Savitskaya made history again on July 25 as the first woman to participate in a spacewalk. During the 3-hour 35-minute excursion, Savitskaya tested a multipurpose tool for electron beam cutting, welding, soldering, and brazing. Less than three months later, on Oct. 11, NASA astronaut Kathryn D. Sullivan completed the first spacewalk by an American woman from space shuttle Challenger during the STS-41G mission. Sullivan helped test the in-orbit transfer of hydrazine using the Orbital Refueling System. With Sally K. Ride as one of Sullivan’s crewmates, the flight marked the first time a space crew included two women. NASA astronaut Kathryn C. Thornton completed her first spacewalk in 1992 during STS-49, the second American woman to walk in space. During this excursion, Thornton tested assembly techniques for the future space station. Thornton earned the recognition as the first woman to make more than one spacewalk when she completed two spacewalks on STS-61, the first mission to service the Hubble Space Telescope.

Helms, the first female long-duration crew member to conduct a spacewalk during the STS-102 docked phase. Right: Godwin during STS-108, the first woman to complete spacewalks at Mir and the space station. NASA astronaut Linda M. Godwin has the distinction as the first woman of any nationality to conduct a spacewalk at Mir. As a member of the STS-76 crew, on March 27, 1996, she took part in a 6-hour 2-minute spacewalk to install handrails and four space exposure experiments onto Mir’s Docking Module. Godwin returned to space on STS-108, and on Dec. 10, 2001, took part in a spacewalk lasting 4 hours 12 minutes to install insulation blankets on the space station, earning the title as the first woman to conduct spacewalks at both Mir and the space station. NASA astronaut Tamara E. Jernigan conducted the first spacewalk by a woman at the embryonic International Space Station. On May 29, 1999, during STS-96, the second space station assembly flight, Jernigan participated in a 7-hour 55-minute spacewalk to install U.S. and Russian cargo cranes, foot restraints, and tool bags. Expedition 2 NASA astronaut Susan J. Helms performed a spacewalk on March 11, 2001, during the STS-102 docked phase to relocate the Pressurized Mating Adaptor-3 (PMA-3) from Node 1’s nadir port to a berth on its port side, to enable the berthing of the Leonardo Multi-Purpose Logistics Module. This marked the first time a woman long-duration crew member performed a spacewalk. Its 8-hour 56-minute duration makes it the longest spacewalk in history. A collage of NASA astronaut Peggy A. Whitson’s 10 spacewalks during space station Expeditions 5, 16, and 50/51. As an Expedition 5 flight engineer, NASA astronaut Peggy A. Whitson participated in her first spacewalk on Aug. 16, 2002. Clad in an Orlan spacesuit and using the Pirs module airlock, she assisted in the installation of six debris shield panels on the Zvezda Service Module. Whitson completed her next five spacewalks, wearing Extravehicular Mobility Units and using the Quest airlock, as commander of Expedition 16, one of the busiest assembly and reconfiguration periods at the space station. The primary objectives for the first three of these spacewalks, conducted on Nov. 9, Nov. 20, and Nov. 24, involved relocating the Harmony Node 2 module and PMA-2 to the front of Destiny and preparing Harmony for the arrival of the Columbus module. Work during the fourth and fifth excursions on Dec. 18 and Jan. 30, 2008, had Whitson conduct inspections and maintenance on the station’s solar array joints. During her next mission to the space station, a 289-day stay that set a new record as the longest single flight by a woman, she completed a further four spacewalks. During Expedition 50, on Jan. 6, 2017, she upgraded the station’s power system by installing three new lithium-ion batteries, and on March 30 installed electrical connections to the PMA-3 recently relocated to Harmony’s top-facing port. During Expedition 51, as station commander once again, Whitson stepped outside on May 12 to replace an avionics package on an external logistics carrier and installed a protective shield on PMA-3. Her 10th and final excursion involved a contingency spacewalk to replace a backup data converter unit that failed three days earlier. With her 10 excursions, Whitson shares a seven-way second place tie for most spacewalks; only one person has conducted more. And with regard to total spacewalk time, she places sixth overall, having spent a total of 60 hours, 21 minutes outside the station. Left: During STS-115, NASA astronaut Heidemarie M. Stefanyshyn-Piper conducts the first of her five career spacewalks. Middle: During STS-116, NASA astronaut Sunita L. Williams after the conclusion of the first of her seven career spacewalks. Right: Expedition 20 NASA astronaut Nicole P. Stott during her STS-128 spacewalk. During STS-115, NASA astronaut Heidemarie M. Stefanyshyn-Piper participated in two of the mission’s three spacewalks. The primary tasks of the excursions on Sept. 12 and 15, 2006, involved the addition of the P3/P4 truss segment including a pair of solar arrays to the station. During her second visit to the space station on STS-126, Stefanyshyn-Piper completed three more spacewalks on Nov. 18, 20, and 22, 2008. Tasks accomplished during these excursions included performing maintenance on one of the solar array joints, replacing a nitrogen tank, and relocating two equipment carts. During Expedition 14, NASA astronaut Sunita L. Williams completed four spacewalks. During the first excursion during the STS-116 docked phase on Dec. 16, 2006, the primary task involved the reconfiguration of the station’s power system. The primary tasks for Williams’ three Expedition 14 spacewalks on Jan. 31, Feb. 4, and Feb. 8, 2007, involved completing the reconfiguration of the station’s cooling system. As a flight engineer during Expedition 32, Williams conducted spacewalks on Aug. 30, 2012, to replace a faulty power routing unit and prepare the station for the arrival of the Nauka module, and on Sept. 5, 2012, to install a spare power unit. During Expedition 33, Williams assumed command of the station, only the second woman to do so, and during a spacewalk on Nov. 1, 2012, repaired an ammonia leak. Across her seven spacewalks, Williams spent 50 hours 40 minutes outside the station. Expedition 20 NASA astronaut Nicole P. Stott completed her one and only spacewalk on Sept. 1, 2009, during the STS-128 docked phase. The objectives of the 6-hour 35-minute excursion involved preparing for the replacement of an empty ammonia tank and retrieving American and European experiments from the Columbus module. Left: NASA astronaut Tracy C. Dyson during Expedition 24, at the conclusion of the first of her four career spacewalks. Middle: During Expedition 48, NASA astronaut Kathleen H. Rubins takes the first of her four career spacewalks. Right: Expedition 59 NASA astronaut Anne C. McClain on the first of her two spacewalks. On July 24, 2010, during Expedition 24, one of the station’s ammonia pump modules failed. The loss of coolant forced controllers to shut down several critical station systems although neither the vehicle nor the crew were ever in danger. The failure resulted in two of the Expedition crew members including NASA astronaut Tracy C. Dyson performing three contingency spacewalks on Aug. 7, 11, and 16, 2010, to replace the pump module. The repairs took nearly 23 hours of spacewalking time. During her next mission, Expedition 71, Dyson began a spacewalk on June 24, 2024, but a leak in her suit forced the cancellation of the excursion after 31 minutes. NASA astronaut Kathleen H. Rubins completed two spacewalks during Expedition 48. During the first, on Aug. 19, 2016, she helped to install the first of two international docking adapters (IDA) to PMA-2 located at the forward end of Harmony. The IDA allows commercial spacecraft to dock autonomously to the space station. During the second excursion on Sept. 1, she retracted a thermal radiator, tightened struts on a solar array joint, and installed high-definition cameras on the outside of the station. Rubins conducted two more spacewalks during her second mission, Expedition 64. On Feb. 28, 2021, she began to assemble and install modification kits for upcoming solar array upgrades, completing the tasks during the next spacewalk on March 5. During her first spacewalk on March 22, 2019, Expedition 59 NASA astronaut Anne C. McClain replaced older nickel hydrogen batteries with newer and more efficient lithium-ion batteries. McClain ventured out for her second spacewalk on April 8 to install a redundant power circuit for the station’s Canadarm robotic arm and cables for more expansive wireless coverage outside the station. Left: Expedition 59 NASA astronaut Christina H. Koch during the first of her six career spacewalks. Right: NASA astronauts Jessica U. Meir, left, and Koch, assisted by their Expedition 61 crewmates, prepare for the first all-woman spacewalk. During Expedition 59, Koch conducted her first spacewalk on March 29. She helped to install three newer lithium-ion batteries to replace six older nickel hydrogen batteries. The Expedition 61 crew conducted a record nine spacewalks between October 2019 and January 2020, and women participated in five of them. Koch’s second and third spacewalks on Oct 6 and 11 continued the work of replacing the station’s batteries. Koch and fellow NASA astronaut Jessica U. Meir made history on Oct. 18 when they floated outside the space station to carry out the first all-woman spacewalk, one of several excursions to replace the station’s batteries. The capsule communicator (capcom), the person in the Mission Control Center at NASA’s Johnson Space Center in Houston who communicates with the astronauts in space, for this historic spacewalk was three-time space shuttle veteran Stephanie D. Wilson. “As much as it’s worth celebrating the first spacewalk with an all-female team, I think many of us are looking forward to it just being normal,” astronaut Dyson said during live coverage of the spacewalk. Koch and Meir conducted two more all-woman spacewalks on Jan. 15 and 20, 2020, continuing the battery replacement tasks. During her six spacewalks, Koch spent 44 hours 15 minutes outside. In addition to her spacewalk accomplishments, Koch set a new record of 328 days for a single spaceflight by a woman.

On Nov. 7, 2021, she stepped outside the space station, the first Chinese woman to do so, wearing a Feitian-2 spacesuit. She spent 6 hours 25 minutes installing a grapple fixture for the facility’s robotic arm. During Expedition 66, NASA astronaut Kayla S. Barron completed two spacewalks. During the first one, on Dec. 2, 2021, Barron replaced a faulty communications antenna. On March 15, 2022, during the second spacewalk, she assembled and installed modification kits required for future solar array upgrades. Italian astronaut Samantha Cristoforetti conducted the first spacewalk by a female European Space Agency astronaut. For the excursion on July 21, 2022, she wore an Orlan spacesuit and used the Poisk module airlock.

  3. NASA has selected four new crew members to participate in the final simulated mission to Mars in 2024 inside the agency’s Human Exploration Research Analog. From left are Kristen Magas, Anderson Wilder, Obaid Alsuwaidi, and Tiffany Snyder.Credit: C7M4 Crew NASA selected a crew of four research volunteers to participate in its last simulated mission to Mars in 2024 within a habitat at the agency’s Johnson Space Center in Houston. Obaid Alsuwaidi, Kristen Magas, Tiffany Snyder, and Anderson Wilder will step into the 650-square-foot HERA (Human Exploration Research Analog) facility on Friday, Nov. 1. Once inside, the team will live and work like astronauts for 45 days. The crew will exit the facility on Monday, Dec. 16, after simulating their return to Earth. Jordan Hundley and Robert Wilson also were named as alternate crew members. Scientists use HERA studies to examine how crew members adapt to isolation, confinement, and remote conditions before NASA sends astronauts on deep space missions to the Moon, Mars, and beyond. The studies provide data about human health and performance in an enclosed environment over time with crews facing different challenges and tasks. The four volunteers will carry out scientific research and operational tasks throughout their simulated mission, including raising shrimp, growing vegetables, and “walking” on the surface of Mars using virtual reality. They will also experience communication delays lasting up to five minutes as they “near” Mars, allowing researchers to see how crews may respond to the type of delays astronauts will encounter in deep space. Astronauts traveling to the Red Planet may encounter one-way communication delays lasting as long as 20 minutes. As with the previous HERA missions, crew members will conduct 18 human health studies during the mission through NASA’s Human Research Program. Collectively, the work helps scientists understand how a spaceflight-like environment contributes to the physiological, behavioral, and psychological health of crew members. Insights gleaned from the studies will allow researchers to develop and test strategies aimed at helping astronauts overcome obstacles on deep space missions.

  4. Representatives of the Artemis Accords signatories, including NASA leadership, met Oct. 14, 2024, for a principals meeting in Milan, during the International Astronautical Congress. With 42 of 45 signatories participating in the event, established and emerging spacefaring nations from every region of the world were represented. Credit: UAE Space Agency A record number of Artemis Accords signatories, including the United States, gathered at the International Astronautical Congress (IAC), the world’s largest global space conference taking place in Milan this week, furthering discussions on the safe and responsible use of space for the benefit of all. During the space conference, top space agency leaders and other government representatives met Oct. 14 to continue advancing implementation of the Artemis Accords, marking the most comprehensive engagement yet among Accords signatories. “As we send humans further into the solar system, collaboration and shared responsibility among nations are more critical than ever,” said NASA Deputy Administrator Pam Melroy. “The Artemis Accords provide a common sense set of principles to guide our work together, and our recent efforts to further their implementation is fostering a remarkable environment of trust and cooperation where all nations can contribute to and benefit from these endeavors.” The high-level meeting was co-chaired by NASA, CSA (Canadian Space Agency) and Italian Space Agency. With 42 of 45 signatories participating, established and emerging spacefaring nations from every region of the world were represented to help create a foundation for future space exploration for the Artemis Generation. Leaders from each nation reflected on how the group can contribute to and advance existing multilateral forums, further technical discussions to inform policy deliberations, and promote and encourage the participation of emerging space nations including the adoption of the Artemis Accords by additional countries. They agreed on recommendations on non-interference, interoperability, release of scientific data, long-term sustainability guidelines, and registration to advance implementing the Artemis Accords. A method of operations was established for the ongoing work of the signatories. “Promoting the participation of emerging space nations and encouraging the adoption of the Artemis Accords is crucial for the entire space,” said Teodoro Valente, president of the Italian Space Agency. “This is a matter of strategic importance in order to ensure the active and meaningful engagement of emerging space nations, both those already part of the Artemis Accords, and those poised to join in the future.” The conversation in Milan built on previous work during a workshop in Montreal in May 2024, where participantsdelved into the topics such as non-interference and interoperability. “Canada is pleased to be part of a growing group of countries committed to the safety and sustainability of outer space activities,” said Lisa Campbell, CSA president. “We are strong supporters of the Artemis Accords and are pleased to have hosted the most recent workshop that advanced work on key aspects of the Artemis Accords. We look forward to continuing this important work in the coming months and years.” In October 2023, signatories agreed on an initial set of mission data parameters to advance transparency and non-interference in conducting space activities. The data parameters identify relevant information about planned lunar surface missions including expected launch dates, the general nature of activities, and landing locations. Recent progress also included work on a database to house them. Several space agencies, including NASA, have submitted mission data to the United Nations Office of Outer Space Affairs for dissemination. Potential focus areas for the next year include further advancing sustainability, including debris management for both lunar orbit and the surface of the Moon. In 2020, the United States and seven other nations were the first to sign the Artemis Accords, which identified a set of principles promoting the beneficial use of space for humanity. The Artemis Accords are grounded in the Outer Space Treaty and other agreements including the Registration Convention, the Rescue and Return Agreement, as well as best practices and norms of responsible behavior that NASA and its partners have supported, including the public release of scientific data. The commitments of the Artemis Accords and efforts by the signatories to advance implementation of these principles support the safe and sustainable exploration of space.

ESA/Hubble & NASA, D. Thilker, J This NASA/ESA Hubble Space Telescope image features the striking spiral galaxy Messier 90 (M90, also NGC 4569), located in the constellation Virgo. In 2019, Hubble released an image of M90 created with Wide Field and Planetary Camera 2 (WFPC2) data taken in 1994, soon after its installation. That WFPC2 image has a distinctive stair-step pattern due to the layout of its sensors. Wide Field Camera 3 (WFC3) replaced WFPC2 in 2009 and Hubble used WFC3 when it turned its aperture to Messier 90 again in 2019 and 2023. That data resulted in this stunning new image, providing a much fuller view of the galaxy’s dusty disk, its gaseous halo, and its bright core. The inner regions of M90’s disk are sites of star formation, seen here in red H-alpha light from nebulae. M90 sits among the galaxies of the relatively nearby Virgo Cluster, and its orbit took M90 on a path near the cluster’s center about three hundred million years ago. The density of gas in the inner cluster weighed on M90 like a strong headwind, stripping enormous quantities of gas from the galaxy and creating the diffuse halo we see around it. This gas is no longer available to form new stars in M90, with the spiral galaxy eventually fading as a result. M90 is located 55 million light-years from Earth, but it’s one of the very few galaxies getting closer to us. Its orbit through the Virgo cluster has accelerated so much that M90 is in the process of escaping the cluster entirely. By happenstance, it’s moving in our direction. Astronomers have measured other galaxies in the Virgo cluster at similar speeds, but in the opposite direction. As M90 continues to move toward us over billions of years, it will also be evolving into a lenticular galaxy.

    What is Air Quality?

    5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Clean air is essential for healthy living, but according to the World Health Organization (WHO), almost 99% of the global population breathes air exceeding their guideline limits of air pollution. “Air quality is a measure of how much stuff is in the air, which includes particulates and gaseous pollutants,” said Kristina Pistone, a research scientist at NASA Ames Research Center. Pistone’s research covers both atmospheric and climate areas, with a focus on the effect of atmospheric particles on climate and clouds. “It’s important to understand air quality because it affects your health and how well you can live your life and go about your day,” Pistone said. We sat down with Pistone to learn more about air quality and how it can have a noticeable impact on human health and the environment. What makes up air quality? There are six main air pollutants regulated by the Environmental Protection Agency (EPA) in the United States: particulate matter (PM), nitrogen oxides, ozone, sulfur oxides, carbon monoxide, and lead. These pollutants come from from natural sources, such as the particulate matter that rises into the atmosphere from fires and desert dust, or from human activity, such as the ozone generated from sunlight reacting to vehicle emissions.

NASA/Jeff Schmaltz What is the importance of air quality? Air quality influences health and quality of life. “Just like we need to ingest water, we need to breathe air,” Pistone said. “We have come to expect clean water because we understand that we need it to live and be healthy, and we should expect the same from our air.” Poor air quality has been tied to cardiovascular and respiratory effects in humans. Short-term exposure to nitrogen dioxide (NO2), for example, can cause respiratory symptoms like coughing and wheezing, and long-term exposure increases the risk of developing respiratory diseases such as asthma or respiratory infections. Exposure to ozone can aggravate the lungs and damage the airways. Exposure to PM2.5 (particulates 2.5 micrometers or smaller) causes lung irritation and has been linked to heart and lung diseases. In addition to its impacts on human health, poor air quality can damage the environment, polluting bodies of water through acidification and eutrophication. These processes kill plants, deplete soil nutrients, and harm animals. Measuring Air Quality: the Air Quality Index (AQI) Air quality is similar to the weather; it can change quickly, even within a matter of hours. To measure and report on air quality, the EPA uses the United States Air Quality Index (AQI). The AQI is calculated by measuring each of the six primary air pollutants on a scale from “Good” to “Hazardous,” to produce a combined AQI numeric value 0-500. “Usually when we’re talking about air quality, we’re saying that there are things in the atmosphere that we know are not good for humans to be breathing all the time,” Pistone said. “So to have good air quality, you need to be below a certain threshold of pollution.” Localities around the world use different thresholds for “good” air quality, which is often dependent on which pollutants their system measures. In the EPA’s system, an AQI value of 50 or lower is considered good, while 51-100 is considered moderate. An AQI value between 100 and 150 is considered unhealthy for sensitive groups, and higher values are unhealthy to everyone; a health alert is issued when the AQI reaches 200. Any value over 300 is considered hazardous, and is frequently associated with particulate pollution from wildfires. NASA Air Quality Research and Data Products Air quality sensors are a valuable resource for capturing air quality data on a local level. In 2022, the Trace Gas GRoup (TGGR) at NASA Ames Research Center deployed Inexpensive Network Sensor Technology for Exploring Pollution, or INSTEP: a new network of low-cost air quality sensors that measures a variety of pollutants. These sensors are capturing air quality data in certain areas in California, Colorado, and Mongolia, and have proven advantageous for monitoring air quality during California’s fire season. The 2024 Airborne and Satellite Investigation of Asian Air Quality (ASIA-AQ) mission integrated sensor data from aircraft, satellites, and ground-based platforms to evaluate air quality over several countries in Asia. The data captured from multiple instruments on these flights, such as the Meteorological Measurement System (MMS) from NASA Ames Atmospheric Science Branch, are used to refine air quality models to forecast and assess air quality conditions. Agency-wide, NASA has a range of Earth-observing satellites and other technology to capture and report air quality data. In 2023, NASA launched the Tropospheric Emissions: Monitoring of Pollution (TEMPO) mission, which measures air quality and pollution over North America. NASA’s Land, Atmosphere Near real-time Capability for Earth Observations (LANCE) tool provides air quality forecasters with measurements compiled from a multitude of NASA instruments, within three hours of its observation. Nitrogen dioxide levels over the D.C./Philadelphia/New York City region measured by TEMPO.NASA/Scientific Visualization Studio Air Quality Resources to Learn More In addition to the EPA’s website, which houses air-quality related sources, the EPA also has a platform called AirNow, which reports the local AQI across the United States and allows users to check air quality levels in their area. Pistone also recommends looking at Purple Air’s real-time map, which displays PM data taken from a crowd-sourced network of low-cost sensors and translates those measurements to estimate AQI. For those concerned about air quality, Pistone recommends checking out https://cleanaircrew.org/ for resources on indoor air quality, breathing safely with wildfire smoke, and even building your own box fan filter. To learn more about air quality research applications, see NASA’s Applied Sciences Program’s Health & Air Quality program area, which details the use of Earth observations to assess and address air quality concerns at local, regional, and national levels. Additionally, the NASA Health and Air Quality Applied Sciences Team (HAQAST) helps connect NASA data and tools with stakeholders to better share and understand the effects of air quality on human health.

NASA/JPL-Caltech Earth planning date: Wednesday, Oct. 16, 2024 Curiosity continues to drive along the western edge of the upper Gediz Vallis channel. After exiting the channel a few weeks ago, we turned north to image the “back side” of the deposits that we investigated on the eastern side before the channel crossing. As a member of the Channel Surfers working group, we believe that acquiring these views will help further our understanding of the geometry, nature, and evolution of these landforms. The bumpy terrain in front of us, however, plays a role in determining our route and length of drive. The rover planners on the team always do a fantastic job in charting the course on this once-in-a-lifetime road trip. I like to imagine Curiosity with the windows down, blaring U2, as she steadily blazes a new path across the sulfate unit. With an eye towards imaging in this two-sol plan, Mastcam crafted a large mosaic of “Fascination Turret” that rises above the channel floor. ChemCam fit an unprecedented number of long distance RMI images in the plan that will document the upper extent of the white stone deposit, the nature of the “Kukenan” mound, and characterize the rocks in Fascination Turret at targets named “Chimney Tree” and “Forgotten Canyon.” In our immediate workspace, ChemCam used the Laser Induced Breakdown Spectroscopy (LIBS) instrument on a laminated (very thinly bedded) bedrock in the workspace at “Puppet Lake” to determine its chemical composition, which will be documented with a coordinating Mastcam image. MAHLI and AXPS teamed up to analyze a cluster of small gray rocks in front of us at “Jumble Lake.” The second sol includes a 25-meter (about 82 feet) drive to the west/northwest as we continue along our path adjacent to the channel. The Environmental theme group included a range of activities such as a Mastcam tau that will measure the optical depth of the atmosphere and constrain aerosol scattering properties, dust devil movies, and a suprahorizon movie to monitor clouds.

  8. 3 min read NASA Selects Two Teams to Advance Life Sciences Research in Space NASA announced two awards Thursday to establish scientific consortia – multi-institutional coalitions to conduct ground-based studies that help address the agency’s goals of maintaining a sustained human presence in space. These consortia will focus on biological systems research in the areas of animal and human models, plants, and microbiology. When fully implemented, the awards for these consortia will total about $5 million. Space biology efforts at NASA use the unique environment of space to conduct experiments impossible to do on Earth. Such research not only supports the health and welfare of astronauts, but results in breakthroughs on diseases such as cancer and neurodegenerative disorders to help protect humanity down on the ground. The awards for the two consortia are for the following areas: Studying space biosphere. The Biology in Space: Establishing Networks for DUrable & REsilient Systems consortium involves a collaborative effort between human/animal, plant, and microbial biologists to ensure an integrated view of the space flight biosphere by enhancing data acquisition, modeling, and testing. It will include participation of more than thirty scientists and professionals working together from at least three institutions. Led by Kristi Morgansen at the University of Washington in Seattle, Washington. Converting human waste into materials for in-space biomanufacturing. The Integrative Anaerobic Digestion and Phototrophic Biosystem for Sustainable Space Habitats and Life Supports consortium will develop an anaerobic digestion process that converts human waste into organic acids and materials that can be used for downstream biomanufacturing applications in space. It will include eight scientists from six different institutions in three different states, including Delaware and Florida. The consortium is led by Yinjie Tang at Washington University in St. Louis, Missouri. Proposals for these consortia were submitted in response to ROSES 2024 Program Element E.11 Consortium in Biological Sciences for a consortium with biological sciences expertise to carry out research investigations and conduct activities that address NASA’s established interests in space life sciences. NASA’s Space Biology Program within the agency’s Biological and Physical Sciences division conducts research across a wide spectrum of biological organization and model systems to probe underlying mechanisms by which organisms acclimate to stressors encountered during space exploration (including microgravity, ionizing radiation, and elevated concentrations of carbon dioxide). This research informs how biological systems regulate and sustain growth, metabolism, reproduction, and development in space and how they repair damage and protect themselves from infection and disease.

  9. NASA’s Sarah Ryan is the Raptor engine lead for NASA’s HLS (Human Landing System) Program at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “With Artemis, we’re moving beyond what NASA did with Apollo and that’s really inspiring, especially to our younger workforce. We’re trying to push farther and it’s really going to drive a lot of technology development on the way there,” Ryan said. “This is a dream come true to be working on Artemis and solving problems so humanity can get back to the Moon then on to Mars.” NASA/Ken Hall A passion for puzzles, problem-solving, and propulsion led Sarah Ryan – a native of Columbus, Ohio – to her current position as Raptor engine lead for NASA’s HLS (Human Landing System) insight team at NASA’s Marshall Space Flight Center in Huntsville, Alabama. The SpaceX Raptor rocket engine powers the company’s Starship and Super Heavy rocket. SpaceX will land astronauts on the Moon for NASA’s Artemis III and Artemis IV missions using the Starship HLS. NASA’s Artemis campaign aims to land the first woman, first person of color, and first international partner astronaut on the Moon. “My team looks at how the components of the Raptor engine work together. Then, we evaluate the performance of the full system to make sure it will accomplish the NASA HLS and Artemis missions,” Ryan said. “I get to see lots of pieces and parts of the puzzle and then look at the system as a whole to make sure it meets NASA’s needs.” While earning a bachelor’s degree from Case Western Reserve University in Cleveland with a dual major in aerospace engineering and mechanical engineering, Ryan had an internship at NASA Marshall, working on a payload for a science mission onboard the International Space Station. After working for a year on satellite design, Ryan returned to NASA Marshall. She noted that the opportunity to work in Marshall’s Engine Systems branch, to be involved with pushing technology forward, and to work on Artemis, really drew her back to NASA. Ryan later earned a master’s degree in aerospace systems from the University of Alabama in Huntsville. When not occupied with rocket engine development, Ryan likes to work on quieter hobbies in her free time, including reading, board games, crocheting, and solving all manner of puzzles – crosswords, number games, word games, and more. Her interest for solving puzzles carries over into her work on the Raptor rocket engines for HLS. “My favorite tasks are the ones that most resemble a puzzle, Ryan said. “If we’re investigating an issue and have a lot of information to assess, I love putting all the pieces together and figuring out what happened, why, and the path forward. I enjoy digging into the data and solving those puzzles.” With Artemis, NASA will explore more of the Moon than ever before, learn how to live and work away from home, and prepare for future human exploration of Mars. NASA’s SLS (Space Launch System) rocket, exploration ground systems, and Orion spacecraft, along with the HLS, next-generation spacesuits, Gateway lunar space station, and future rovers are NASA’s foundation for deep space exploration.

The C-130 is supporting the NASA-ISRO Synthetic Aperture Radar (NISAR) mission.NASA/Madison Griffin NASA’s globetrotting C-130 Hercules team is carrying out a cargo transport mission to Bengaluru, India, in support of the NASA-ISRO Synthetic Aperture Radar (NISAR) mission. The C-130 departed from NASA’s Wallops Flight Facility in Virginia, Tuesday, Oct. 15, to embark on the multi-leg, multi-day journey. The flight path will take the aircraft coast to coast within the United States, across the Pacific Ocean with planned island stops, and finally to its destination in India. The goal: safely deliver NISAR’s radar antennae reflector, one of NASA’s contributions to the mission, for integration on the spacecraft. NISAR is a joint mission between NASA and ISRO (Indian Space Research Organisation). The cargo transport mission will encompass approximately 24,500 nautical miles and nearly 80 hours of flight time for the C-130 and crew. The flight plan includes strategic stops and rest days to service the aircraft and reduce crew fatigue from long-haul segments of the flight and multiple time zone changes. The flight crew inspects the aircraft prior to departure from NASA Wallops.NASA/Madison Griffin The C-130’s cargo compartment has plenty of space to hold the more than 2,800-pound payload containing the radar antennae reflector once retrieved from California.NASA/Madison Griffin The first stop for the C-130 was March Air Reserve Base located in Riverside County, California, to retrieve the radar antennae reflector from NASA’s Jet Propulsion Laboratory in Southern California. Additional stops during the mission include Hickman Air Force Base, Hawaii; Andersen Air Force Base, Guam; Clark Air Base, Philippines; and Hindustan Aeronautics Limited Airport in Bengaluru, India. This is the C-130 and crew’s third cargo transport to India in support of the NISAR mission, with prior flights in July 2023 and March 2024. For more information, visit nasa.gov/wallops.

  12. 5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) New findings using data from NASA’s IXPE (Imaging X-ray Polarimetry Explorer) mission offer unprecedented insight into the shape and nature of a structure important to black holes called a corona. A corona is a shifting plasma region that is part of the flow of matter onto a black hole, about which scientists have only a theoretical understanding. The new results reveal the corona’s shape for the first time, and may aid scientists’ understanding of the corona’s role in feeding and sustaining black holes. This illustration of material swirling around a black hole highlights a particular feature, called the “corona,” that shines brightly in X-ray light. In this depiction, the corona can be seen as a purple haze floating above the underlying accretion disk, and extending slightly inside of its inner edge. The material within the inner accretion disk is incredibly hot and would glow with a blinding blue-white light, but here has been reduced in brightness to make the corona stand out with better contrast. Its purple color is purely illustrative, standing in for the X-ray glow that would not be obvious in visible light. The warp in the disk is a realistic representation of how the black hole’s immense gravity acts like an optical lens, distorting our view of the flat disk that encircles it. NASA/Caltech-IPAC/Robert Hurt Many black holes, so named because not even light can escape their titanic gravity, are surrounded by accretion disks, debris-cluttered whirlpools of gas. Some black holes also have relativistic jets – ultra-powerful outbursts of matter hurled into space at high speed by black holes that are actively eating material in their surroundings. Less well known, perhaps, is that snacking black holes, much like Earth’s Sun and other stars, also possess a superheated corona. While the Sun’s corona, which is the star’s outermost atmosphere, burns at roughly 1.8 million degrees Fahrenheit, the temperature of a black hole corona is estimated at billions of degrees. Astrophysicists previously identified coronae among stellar-mass black holes – those formed by a star’s collapse – and supermassive black holes such as the one at the heart of the Milky Way galaxy. “Scientists have long speculated on the makeup and geometry of the corona,” said Lynne Saade, a postdoctoral researcher at NASA’s Marshall Space Flight Center in Huntsville, Alabama, and lead author of the new findings. “Is it a sphere above and below the black hole, or an atmosphere generated by the accretion disk, or perhaps plasma located at the base of the jets?” Enter IXPE, which specializes in X-ray polarization, the characteristic of light that helps map the shape and structure of even the most powerful energy sources, illuminating their inner workings even when the objects are too small, bright, or distant to see directly. Just as we can safely observe the Sun’s corona during a total solar eclipse, IXPE provides the means to clearly study the black hole’s accretion geometry, or the shape and structure of its accretion disk and related structures, including the corona. “X-ray polarization provides a new way to examine black hole accretion geometry,” Saade said. “If the accretion geometry of black holes is similar regardless of mass, we expect the same to be true of their polarization properties.” IXPE demonstrated that, among all black holes for which coronal properties could be directly measured via polarization, the corona was found to be extended in the same direction as the accretion disk – providing, for the first time, clues to the corona’s shape and clear evidence of its relationship to the accretion disk. The results rule out the possibility that the corona is shaped like a lamppost hovering over the disk. The research team studied data from IXPE’s observations of 12 black holes, among them Cygnus X-1 and Cygnus X-3, stellar-mass binary black hole systems about 7,000 and 37,000 light-years from Earth, respectively, and LMC X-1 and LMC X-3, stellar-mass black holes in the Large Magellanic Cloud more than 165,000 light-years away. IXPE also observed a number of supermassive black holes, including the one at the center of the Circinus galaxy, 13 million light-years from Earth, and those in galaxies NGC 1068 and NGC 4151, 47 million light-years away and nearly 62 million light-years away, respectively. Stellar mass black holes typically have a mass roughly 10 to 30 times that of Earth’s Sun, whereas supermassive black holes may have a mass that is millions to tens of billions of times larger. Despite these vast differences in scale, IXPE data suggests both types of black holes create accretion disks of similar geometry. That’s surprising, said Marshall astrophysicist Philip Kaaret, principal investigator for the IXPE mission, because the way the two types are fed is completely different. “Stellar-mass black holes rip mass from their companion stars, whereas supermassive black holes devour everything around them,” he said. “Yet the accretion mechanism functions much the same way.” That’s an exciting prospect, Saade said, because it suggests that studies of stellar-mass black holes – typically much closer to Earth than their much more massive cousins – can help shed new light on properties of supermassive black holes as well. The team next hopes to make additional examinations of both types. Saade anticipates there’s much more to glean from X-ray studies of these behemoths. “IXPE has provided the first opportunity in a long time for X-ray astronomy to reveal the underlying processes of accretion and unlock new findings about black holes,” she said. The complete findings are available in the latest issue of The Astrophysical Journal.

The camera is located high on the rover mast, and here the rover is looking back in the direction of the Jezero crater floor. This image was acquired on October 4th, 2024 (Sol 1288) at the local mean solar time of 12:51:26. NASA/JPL-Caltech Throughout the past week, Perseverancehas continued marching up the Jezero crater rim. This steep ascent through the Martian regolith (soil) can prove to be slow driving for the rover, as the wheels can slip on the steepest areas. This is like trying to run up a hill of sand on a beach – with every step forward, you also slip back a little way down the hill! This just means the Science and Engineering teams work together closely to plan slow and steady drives through this tricky terrain. Driving through the Mount Ranier quadrangle, the team identified a relatively obstacle-free path to reach the crater rim which they designated Summerland Trail, aptly named from a very popular hiking trail that ascends Mount Ranier. Perseverance is trekking to the next waypoint near an outcrop of rocks called Pico Turquino, where the science team hopes to perform its next proximity science investigations with its instruments PIXL and back-online SHERLOC. While roving along Summerland Trail, Perseverance is constantly observing the surrounding terrain. SuperCam and Mastcam-Z have been observing rocks on the ground and on a distant hill, called Crystal Creek. In addition, during this time Perseverance can put its eyes to the sky to make observations of the sun and atmosphere. Last week, the Mastcam-Z camera captured images of Phobos (one of Mars’ two moons) transiting in front of the sun! This image, showing Phobos transiting in front of the sun, was acquired using Perseverance’s Left Mastcam-Z camera.

Due to launch in the early 2030s, NASA’s DAVINCI mission will investigate whether Venus — a sweltering world wrapped in an atmosphere of noxious gases — once had oceans and continents like Earth. Consisting of a flyby spacecraft and descent probe, DAVINCI will focus on a mountainous region called Alpha Regio, a possible ancient continent. Though a handful of international spacecraft plunged through Venus’ atmosphere between 1970 and 1985, DAVINCI’s probe will be the first to capture images of this intriguing terrain ever taken from below Venus’ thick and opaque clouds. But how does a team prepare for a mission to a planet that hasn’t seen an atmospheric probe in nearly 50 years, and that tends to crush or melt its spacecraft visitors? Scientists leading the DAVINCI mission started by using modern data-analysis techniques to pore over decades-old data from previous Venus missions. Their goal is to arrive at our neighboring planet with as much detail as possible. This will allow scientists to most effectively use the probe’s descent time to collect new information that can help answer longstanding questions about Venus’ evolutionary path and why it diverged drastically from Earth’s. On the left, a new and more detailed view of Venus’ Alpha Regio region developed by scientists on NASA’s DAVINCI mission to Venus, due to launch in the early 2030s. On the right is a less detailed map created using radar altimeter data collected by NASA’s Magellan spacecraft in the early 1990s. The colors on the maps depict topography, with dark blues identifying low elevations and browns identifying high elevations. To make the map on the left, the DAVINCI science team re-analyzed Magellan data and supplemented it with radar data collected on three occasions from the Arecibo Observatory in Puerto Rico, and used machine vision computer models to scrutinize the data and fill in gaps in information. The red ellipses on each image mark the area DAVINCI’s probe will descend over as it collects data on its way toward the surface. Jim Garvin/NASA’s Goddard Space Flight Center Between 1990 and 1994, NASA’s Magellan spacecraft used radar imaging and altimetry to map the topography of Alpha Regio from Venus’ orbit. Recently, NASA’s DAVINICI’s team sought more detail from these maps, so scientists applied new techniques to analyze Magellan’s radar altimeter data. They then supplemented this data with radar images taken on three occasions from the former Arecibo Observatory in Puerto Rico and used machine vision computer models to scrutinize the data and fill in gaps in information at new scales (less than 0.6 miles, or 1 kilometer). As a result, scientists improved the resolution of Alpha Regio maps tenfold, predicting new geologic patterns on the surface and prompting questions about how these patterns could have formed in Alpha Regio’s mountains. Benefits of Looking Backward Old data offers many benefits to new missions, including information about what frequencies, parts of spectrum, or particle sizes earlier instruments covered so that new instruments can fill in the gaps. At NASA Space Science Data Coordinated Archive, which is managed out of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, staff restore and digitize data from old spacecraft. That vintage data, when compared with modern observations, can show how a planet changes over time, and can even lead to new discoveries long after missions end. Thanks to new looks at Magellan observations, for instance, scientists recently found evidence of modern-day volcanic activity on Venus. The three images in this carousel were taken in March 2024 at NASA Space Science Data Coordinated Archive at NASA’s Goddard Space Flight Center in Greenbelt, Md. The first shows stacked boxes of microfilm with data from Apollo missions. The middle image shows miniaturized records from NASA’s 1964 Mariner 4 flyby mission to Mars. And the final image shows a view of Jupiter from NASA’s Pioneer 10 flyby mission to the outer planets, which launched on March 2, 1972.

Magellan was among the first missions to be digitally archived in NASA’s publicly accessible online repository of planetary mission data. But the agency has reams of data — much of it not yet digitized — dating back to 1958, when the U.S. launched its first satellite, Explorer 1. Data restoration is a complex and resource-intensive job, and NASA prioritizes digitizing data that scientists need. With three forthcoming missions to Venus — NASA’s DAVINCI and VERITAS, plus ESA’s (European Space Agency) Envision — space data archive staff are helping scientists access data from Pioneer Venus, NASA’s last mission to drop probes into Venus’ atmosphere in 1978. Mosaic of Venus Alpha Regio is one of the most mysterious spots on Venus. Its terrain, known as “tessera,” is similar in appearance to rugged Earth mountains, but more irregular and disorderly. So called because they resemble a geometric parquet floor pattern, tesserae have been found only on Venus, and DAVINCI will be the first mission to explore such terrain in detail and to map its topography. DAVINCI’s probe will begin photographing Alpha Regio — collecting the highest-resolution images yet — once it descends below the planet’s clouds, starting at about 25 miles, or 40 kilometers, altitude. But even there, gases in the atmosphere scatter light, as does the surface, such that these images will appear blurred. Could Venus once have been a habitable world with liquid water oceans — like Earth? This is one of the many mysteries associated with our shrouded sister world. Credit: NASA’s Goddard Space Flight Center DAVINCI scientists are working on a solution. Recently, scientists re-analyzed old Venus imaging data using a new artificial-intelligence technique that can sharpen the images and use them to compute three-dimensional topographic maps. This technique ultimately will help the team optimize DAVINCI’s images and maps of Alpha Regio’s mountains. The upgraded images will give scientists the most detailed view ever — down to a resolution of 3 feet, or nearly 1 meter, per pixel — possibly allowing them to detect small features such as rocks, rivers, and gullies for the first time in history. “All this old mission data is part of a mosaic that tells the story of Venus,” said Jim Garvin, DAVINCI principal investigator and chief scientist at NASA Goddard. “A story that is a masterpiece in the making but incomplete.” By analyzing the surface texture and rock types at Alpha Regio, scientists hope to determine if Venusian tesserae formed through the same processes that create mountains and certain volcanoes on Earth.

    Imagining the Future

    NASA A space shuttle lifts off high above the surrounding land in this Aug. 1, 1973, illustration. With 135 missions flown over 30 years, NASA’s shuttle fleet achieved numerous firsts and opened space up to more people than ever before. Each space shuttle consisted of three major components: the orbiter, which housed the crew, a large external tank that held fuel for the main engines, and two solid rocket boosters that provided most of the shuttle’s lift during the first two minutes of flight. All the components were reused except for the external fuel tank, which burned up in the atmosphere after each launch. The space shuttle was the world’s first reusable spacecraft.

  16. 4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Researchers think meltwater beneath Martian ice could support microbial life. The white material seen within this Martian gully is believed to be dusty water ice. Scientists believe this kind of ice could be an excellent place to look for microbial life on Mars today. This image, showing part of a region called Dao Vallis, was captured by NASA’s Mars Reconnaissance Orbiter in 2009.NASA/JPL-Caltech/University of Arizona These holes, captured on Alaska’s Matanuska Glacier in 2012, are formed by cryoconite — dust particles that melt into the ice over time, eventually forming small pockets of water below the glacier’s surface. Scientists believe similar pockets of water could form within dusty water ice on Mars.Kimberly Casey CC BY-NC-SA 4.0 While actual evidence for life on Mars has never been found, a new NASA study proposes microbes could find a potential home beneath frozen water on the planet’s surface. Through computer modeling, the study’s authors have shown that the amount of sunlight that can shine through water ice would be enough for photosynthesis to occur in shallow pools of meltwater below the surface of that ice. Similar pools of water that form within ice on Earth have been found to teem with life, including algae, fungi, and microscopic cyanobacteria, all of which derive energy from photosynthesis. “If we’re trying to find life anywhere in the universe today, Martian ice exposures are probably one of the most accessible places we should be looking,” said the paper’s lead author, Aditya Khuller of NASA’s Jet Propulsion Laboratory in Southern California. Mars has two kinds of ice: frozen water and frozen carbon dioxide. For their paper, published in Nature Communications Earth & Environment, Khuller and colleagues looked at water ice, large amounts of which formed from snow mixed with dust that fell on the surface during a series of Martian ice ages in the past million years. That ancient snow has since solidified into ice, still peppered with specks of dust. Although dust particles may obscure light in deeper layers of the ice, they are key to explaining how subsurface pools of water could form within ice when exposed to the Sun: Dark dust absorbs more sunlight than the surrounding ice, potentially causing the ice to warm up and melt up to a few feet below the surface. The white edges along these gullies in Mars’ Terra Sirenum are believed to be dusty water ice. Scientists think meltwater could form beneath the surface of this kind of ice, providing a place for possible photosynthesis. This is an enhanced-color image; the blue color would not actually be perceptible to the human eye.NASA/JPL-Caltech/University of Arizona Mars scientists are divided about whether ice can actually melt when exposed to the Martian surface. That’s due to the planet’s thin, dry atmosphere, where water ice is believed to sublimate — turn directly into gas — the way dry ice does on Earth. But the atmospheric effects that make melting difficult on the Martian surface wouldn’t apply below the surface of a dusty snowpack or glacier. Thriving Microcosms On Earth, dust within ice can create what are called cryoconite holes — small cavities that form in ice when particles of windblown dust (called cryoconite) land there, absorb sunlight, and melt farther into the ice each summer. Eventually, as these dust particles travel farther from the Sun’s rays, they stop sinking, but they still generate enough warmth to create a pocket of meltwater around them. The pockets can nourish a thriving ecosystem for simple lifeforms.. “This is a common phenomenon on Earth,” said co-author Phil Christensen of Arizona State University in Tempe, referring to ice melting from within. “Dense snow and ice can melt from the inside out, letting in sunlight that warms it like a greenhouse, rather than melting from the top down.” Christensen has studied ice on Mars for decades. He leads operations for a heat-sensitive camera called THEMIS (Thermal Emission Imaging System) aboard NASA’s 2001 Mars Odyssey orbiter. In past research, Christensen and Gary Clow of the University of Colorado Boulder used modeling to demonstrate how liquid water could form within dusty snowpack on the Red Planet. That work, in turn, provided a foundation for the new paper focused on whether photosynthesis could be possible on Mars. In 2021, Christensen and Khuller co-authored a paper on the discovery of dusty water ice exposed within gullies on Mars, proposing that many Martian gullies form by erosion caused by the ice melting to form liquid water. This new paper suggests that dusty ice lets in enough light for photosynthesis to occur as deep as 9 feet (3 meters) below the surface. In this scenario, the upper layers of ice prevent the shallow subsurface pools of water from evaporating while also providing protection from harmful radiation. That’s important, because unlike Earth, Mars lacks a protective magnetic field to shield it from both the Sun and radioactive cosmic ray particles zipping around space. The study authors say the water ice that would be most likely to form subsurface pools would exist in Mars’ tropics, between 30 degrees and 60 degrees latitude, in both the northern and southern hemispheres. Khuller next hopes to re-create some of Mars’ dusty ice in a lab to study it up close. Meanwhile, he and other scientists are beginning to map out the most likely spots on Mars to look for shallow meltwater — locations that could be scientific targets for possible human and robotic missions in the future.

  17. 4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Jacquelyn Shuman visually assesses a prescribed fire at Ft. Stewart in Georgia, working with partner organizations as part of the Department of Defense Ft. Stewart 2024 Fire Research Campaign. USFS/Linda Chappell Jacquelyn Shuman, FireSense Project Scientist at NASA Ames Research Center, originally wanted to be a veterinarian. By the time she got to college, Shuman had switched interests to biology, which became a job teaching middle and high school science. Teaching pivoted to finance for a year, before Shuman returned to the science world to pursue a PhD. It was in a forest ecology class taught by her future PhD advisor, Herman “Hank” Shugart, that she first discovered a passion for ecosystems and dynamic vegetation that led her into the world of fire science, and eventually to NASA Ames. While Shuman’s path into the world of fire science was not a direct one, she views her diverse experiences as the key to finding a fulfilling career. “Do a lot of different things and try a lot of different things, and if one thing isn’t connecting with you, then do something different,” Shuman said. Diving into the World of Fire Shuman’s PhD program focused on boreal forest dynamics across Russia, examining how the forest changes in response to climate change and wildfire. During her research, she worked mainly with scientists from Russia, Canada, and the US through the Northern Eurasia Earth Science Partnership Initiative (NEESPI), where Shugart served as the NEESPI Chief Scientist. “The experience of having a highly supportive mentor, being a part of the NEESPI community, and working alongside other inspiring female scientists from across the globe helped me to stay motivated within my own research,” Shuman said. After completing her PhD, Shuman wanted to become involved in collaborative science with a global impact, which led her to the National Center for Atmospheric Research (NCAR). There, she spent seven years working as a project scientist on the Next Generation Ecosystem Experiment NGEE-Tropics) on a dynamic vegetation model project called FATES (Functionally Assembled Terrestrial Ecosystem Simulator). As part of the FATES team, Shuman used computer modeling to test vegetation structure and function in tropical and boreal forests after wildfires, and was the lead developer for updating the fire portion of the model. This figure shows fire characteristics from an Earth system model that uses vegetation structure and interactive fire. The FATES model captures the fire intensity associated with burned land and grass growth in the Southern Hemisphere. Shuman et al. 2024 GMD Fire has also played a powerful role in Shuman’s personal life. In 2021, the Marshall Fire destroyed neighborhoods near her hometown of Boulder, Colorado, causing over $513 million of damage and securing its place as the state’s most destructive wildfire. Despite this, Shuman is determined to not live in fear. “Fire is part of our lives, it’s a part of the Earth system, and it’s something we can plan for. We can live more sustainably with fires.” The way to live safely in a fire-inclusive ecosystem, according to Shuman, is to develop ways to accurately track and forecast wildfires and smoke, and to respond to them efficiently: efforts the fire community is continuously working on improving. The Fire Science Community Collaboration is a critical element of wildland fire management. Fire science is a field that involves practitioners such as firefighters and land managers, but also researchers such as modelers and forecasters; the most effective efforts, according to Shuman, come when this community works together. “People in fire science might be out in the field and carrying a drip torch and marching along in the hilltops and the grasslands or be behind a computer and analyzing remote sensing data,” Shuman said. “We need both pieces.” Protecting communities from wildfire impacts is one of the most fulfilling aspects of Shuman’s career, and a goal that unites this community. “Fire research poses tough questions, but the people who are thinking about this are the people who are acting on it,” Shuman said. “They are saying, ‘What can we do? How can we think about this? What information do we need? What are the questions?’ It’s a special community to be a part of.” Looking to the Future of Fire Currently at NASA Ames Research Center, Shuman is the Project Scientist for FireSense: a project focused on delivering NASA science and technology to practitioners and operational agencies. Shuman acts as the lead for the project office, identifying and implementing tools and strategies. Shuman still does ecosystem modeling work, including implementing vegetation models that forecast the impact of fire, but also spends time traveling to active fires across the country so she can help partners implement NASA tools and strategies in real time. FireSense Project Scientist Jacquelyn Shuman stands with Roger Ottmar (United States Forest Service), surveying potential future locations for prescribed burns in Fishlake National Forest. NASA Ames/Milan Loiacono “Right now, many different communities are all recognizing that we can partner to identify the best path forward,” Shuman said. “We have an opportunity to use everyone’s strengths and unique perspectives. It can be a devastating thing for a community and an ecosystem when a fire happens. Everyone is interested in using all this collective knowledge to do more, together.” Written by Molly Medin, NASA Ames Research Center Share Details Last Updated Oct 17, 2024 Related TermsGeneralEarth ScienceEarth Science Division Explore More 4 min read Navigating Space and Sound: Jesse Bazley Supports Station Integration and Colleagues With Disabilities Article 18 hours ago 3 min read Sacrifice and Success: NASA Engineer Honors Family Roots Article 19 hours ago 7 min read What is a Coral Reef?

  19. Science Launching on SpaceX's 31st Cargo Resupply Mission to the Space Station
  20. NASA and its international partners are launching scientific investigations on SpaceX’s 31st commercial resupply services mission to the International Space Station including studies of solar wind, a radiation-tolerant moss, spacecraft materials, and cold welding in space. The company’s Dragon cargo spacecraft is scheduled to launch from NASA’s Kennedy Space Center in Florida. Read more about some of the research making the journey to the orbiting laboratory: Measuring solar wind The CODEX (COronal Diagnostic EXperiment) examines the solar wind, creating a globally comprehensive data set to help scientists validate theories for what heats the solar wind – which is a million degrees hotter than the Sun’s surface – and sends it streaming out at almost a million miles per hour. The investigation uses a coronagraph, an instrument that blocks out direct sunlight to reveal details in the outer atmosphere or corona. The instrument takes multiple daily measurements that determine the temperature and speed of electrons in the solar wind, along with the density information gathered by traditional coronagraphs. A diverse international team has been designing, building, and testing the instrument since 2019 at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Multiple missions have studied the solar wind, and CODEX could add important pieces to this complex puzzle. When the solar wind reaches Earth, it triggers auroras at the poles and can generate space weather storms that sometimes disrupt satellite and land-based communications and power grids on the ground. Understanding the source of the solar wind could help improve space-weather forecasts and response. A worker prepares the CODEX (COronal Diagnostic EXperiment) instrument for launch.NASA Antarctic moss in space A radiation tolerance experiment, ARTEMOSS, uses a live Antarctic moss, Ceratodon purpureus, to study how some plants better tolerate exposure to radiation and to examine the physical and genetic response of biological systems to the combination of cosmic radiation and microgravity. Little research has been done on how these two factors together affect plant physiology and performance, and results could help identify biological systems suitable for use in bioregenerative life support systems on future missions. Mosses grow on every continent on Earth and have the highest radiation tolerance of any plant. Their small size, low maintenance, ability to absorb water from the air, and tolerance of harsh conditions make them suitable for spaceflight. NASA chose the Antarctic moss because that continent receives high levels of radiation from the Sun. The investigation also could identify genes involved in plant adaptation to spaceflight, which might be engineered to create strains tolerant of deep-space conditions. Plants and other biological systems able to withstand the extreme conditions of space also could provide food and other necessities in harsh environments on Earth. A Petri plate holding Antarctic moss colonies is prepared for launch at Brookhaven National Laboratory. SETI Institute Exposing materials to space The Euro Material Ageing investigation from ESA (European Space Agency) includes two experiments studying how certain materials age while exposed to space. The first experiment, developed by CNES (Centre National d’Etudes Spatiales), includes materials selected from 15 European entities through a competitive evaluation process that considered novelty, scientific merit, and value for the material science and technology communities. The second experiment looks at organic samples and their stability or degradation when exposed to ultraviolet radiation not filtered by Earth’s atmosphere. The exposed samples are recovered and returned to Earth. Predicting the behavior and lifespan of materials used in space can be difficult because facilities on the ground cannot simultaneously test for all aspects of the space environment. These limitations also apply to testing organic compounds and minerals that are relevant for studying comets, asteroids, the surface of Mars, and the atmospheres of planets and moons. Results could support better design for spacecraft and satellites, including improved thermal control, and the development of sensors for research and industrial applications. Preparation of one of the Euro Material Ageing’s experiments for launch.Centre National d’Etudes Spatiales Repairing spacecraft from the inside Nanolab Astrobeat investigates using cold welding to repair perforations in the outer shell or hull of a spacecraft from the inside. Less force is needed to fuse metallic materials in space than on Earth, and cold welding could be an effective way to repair spacecraft. Some micrometeoroids and space debris traveling at high velocities could perforate the outer surfaces of spacecraft, possibly jeopardizing mission success or crew safety. The ability to repair impact damage from inside a spacecraft may be more efficient and safer for crew members. Results also could improve applications of cold welding on Earth as well. The investigation also involves a collaboration with cellist Tina Guo with support from New York University Abu Dhabi to store musical compositions on the Astrobeat computer. Investigators planned to stream this “Music from Space” from the space station to the International Astronautical Congress in Milan and to Abu Dhabi after the launch.

It is that expertise that enables pilots to help researchers learn how an aircraft can fly their technology innovations and save time and money, while increasing the innovation’s readiness for use. NASA pilots detailed how they help researchers find the right fit for experiments that might not advance without proving that they work in flight as they do in modeling, simulation, and ground tests at the Ideas to Flight Workshop on Sept. 18 at NASA’s Armstrong Flight Research Center in Edwards, California. “Start the conversation early and make sure you have the right people in the conversation,” said Tim Krall, a NASA Armstrong flight operations engineer. “What we are doing better is making sure pilots are included earlier in a flight project to capitalize on their experience and knowledge.” Flight research is often used to prove or refine computer models, try out new systems, or increase a technology’s readiness. Sometimes, pilots guide a research project involving experimental aircraft. For example, pilots play a pivotal role on the X-59 aircraft, which will fly faster than the speed of sound while generating a quiet thump, rather than a loud boom. In the future, NASA’s pilots with fly the X-59 over select U.S. communities to gather data about how people on the ground perceive sonic thumps. NASA will provide this information to regulators to potentially change regulations that currently prohibit commercial supersonic flight over land. Mark Russell, center, a research pilot at NASA’s Glenn Research Center in Hampton, Virginia, explains the differences in flight environments at different NASA centers. Jim Less, a NASA pilot at NASA’s Armstrong Flight Research Center in Edwards, California, left, Russell, and Nils Larson, NASA Armstrong chief X-59 aircraft pilot and senior advisor on flight research, provided perspective on flight research at the Ideas to Flight Workshop on Sept. 18 at NASA Armstrong.NASA/Genaro Vavuris “We have been involved with X-59 aircraft requirements and design process from before it was an X-plane,” said Nils Larson, NASA chief X-59 aircraft pilot and senior advisor on flight research. “I was part of pre-formulation and formulation teams. I was also on the research studies and brought in NASA pilot Jim Less in for a second opinion. Because we had flown missions in the F-15 and F-18, we knew the kinds of systems, like autopilots, that we need to get the repeatability and accuracy for the data.” NASA pilots’ experience can provide guidance to enable a wide range of flight experiments. A lot of times researchers have an idea of how to get the required flight data, but sometimes, Larson explains, while there are limits to what an aircraft can do – like flying the DC-8 upside down, there are maneuvers that given the right mitigations, training, and approval could simulate those conditions. Less says he’s developed an approach to help focus researchers: “What do you guys really need? A lot of what we do is mundane, but anytime you go out and fly, there is some risk. We don’t want to take a risk if we are going after data that nobody needs, or it is not going to serve a purpose, or the quality won’t work.” Justin Hall, left, attaches the Preliminary Research Aerodynamic Design to Land on Mars, or Prandtl-M, glider onto the Carbon-Z Cub, which Justin Link steadies. Hall and Link are part of a team from NASA’s Armstrong Flight Research Center in Edwards, California, that uses an experimental magnetic release mechanism to air launch the glider.NASA/Lauren Hughes Sometimes, a remotely piloted aircraft can provide an advantage to achieve NASA’s research priorities, said Justin Hall, NASA Armstrong’s subscale aircraft laboratory chief pilot. “We can do things quicker, at a lower cost, and the subscale lab offers unique opportunities. Sometimes an engineer comes in with an idea and we can help design and integrate experiments, or we can even build an aircraft and pilot it.” Most research flights are straight and level like driving a car on the highway. But there are exceptions. “The more interesting flights require a maneuver to get the data the researcher is looking for,” Less said. “We mounted a pod to an F/A-18 with the landing radar that was going to Mars and they wanted to simulate Martian reentry using the airplane. We went up high and dove straight at the ground.” Another F/A-18 experiment tested the flight control software for the Space Launch System rocket for the Artemis missions. “A rocket takes off vertically and it has to pitch over 90 degrees,” Less explained. “We can’t quite do that in an F-18, but we could start at about a 45-degree angle and then push 45 degrees nose low to simulate the whole turn. That’s one of the fun parts of the job, trying to figure out how to get the data you want with the tools we have.” NASA pilot Jim Less is assisted by life support as he is fitted with a pilot breathing monitoring system. The sensing system is attached to a pilot’s existing gear to capture real-time physiological, breathing gas, and cockpit environmental data.NASA/Carla Thomas Share Details Last Updated Oct 16, 2024 EditorDede DiniusContactJay Levinejay.levine-1@nasa.govLocationArmstrong Flight Research Center Related TermsArmstrong Flight Research CenterAeronauticsAeronautics ResearchAeronautics Research Mission DirectorateQuesst (X-59)Technology Research Explore More 3 min read Sacrifice and Success: NASA Engineer Honors Family Roots Article 2 hours ago 4 min read Sacrificio y Éxito: Ingeniero de la NASA honra sus orígenes familiares Article 2 hours ago 3 min read NASA Spotlight: Felipe Valdez, an Inspiring Engineer Article 3 days ago Keep Exploring Discover More Topics From NASA Armstrong Flight Research Center Armstrong Capabilities & Facilities NASA Aircraft Armstrong Technologies View the full article
  22. A salute is widely recognized as a display of respect, but did you know it also means ‘hello’ in American Sign Language? It is one of the signs that Jesse Bazley, International Space Station/Commercial Low Earth Orbit Development Program integration team lead, subtly incorporates into his daily interactions with colleagues at NASA’s Johnson Space Center in Houston. In May 2021, Jesse Bazley worked his final shift as an Environmental and Thermal Operating Systems flight controller in the Mission Control Center at NASA’s Johnson Space Center in Houston. Image courtesy of Jesse Bazley Bazley is hard of hearing, which has at times presented challenges in his daily work – particularly during his stint as an Environmental and Thermal Operating Systems flight controller for the space station. “Working on console [in the Mission Control Center], you must listen to dozens of voice loops at a time, sometimes in different languages,” he said, adding that the standard-issue headset for flight controllers was not compatible with his hearing aids. Bazley adapted by obtaining a headset that fit over his hearing aids, learning how to adjust the audio system’s volume, and limiting over-the-air discussions when possible. Bazley has been part of the NASA team for 17 years, filling a variety of roles that support the International Space Station. One of his proudest achievements occurred early in his tenure. Bazley was an intern at Marshall Space Flight Center in Huntsville, Alabama, in 2006 when the space station’s Water Recovery System was being tested. The system converts the station’s wastewater into drinkable water for the crew. When he arrived at Johnson one year later, his first assignment was to assist with the system’s procedure and display development for its incorporation into the space station’s core operations. “Now, 16 years later, it is commonplace for the space station to ‘turn yesterday’s coffee into tomorrow’s coffee’,” he said. Jesse Bazley supporting the Atmosphere and Consumables Engineer console during the STS-127 mission in July 2009. NASA His favorite project so far has been integrating the station’s Thermal Amine Scrubber – which removes carbon dioxide from the air – into station operations. “I worked it from the beginning of NASA’s involvement, helping the provider with software testing and the integration of a brand-new Mission Control Center communications architecture,” he said. Today, Bazley works to integrate subject matter experts from Johnson’s Flight Operations Directorate (FOD) into the processes of the International Space Station and Commercial Low Earth Orbit Development Programs. “I help pull together FOD positions on topics and coordinate reviews of provider materials to ensure that the operations perspective is maintained as development moves forward,” he explained. While Bazley no longer supports a console, he must continue adapting to difficult hearing environments. He uses the captioning tools available through videoconferencing software during frequent team meetings, for example. “It’s important to understand that people have visible and invisible disabilities,” he said. “Sometimes their request for a remote option is not because they want to avoid an in-person meeting. It may be that they work best using the features available in that virtual environment.” Bazley also chairs the No Boundaries Employee Resource Group, which promotes the development, inclusion, and innovation of Johnson’s workforce with a focus on employees with disabilities and employees who are caregivers of family members with disabilities. From these diverse roles and experiences, Bazley has learned to listen to his gut instincts. “In flight operations, you must work with short timelines when things happen in-orbit, so you have to trust your training,” he said. “Understanding when you have enough information to proceed is critical to getting things done.” Bazley looks forward to the further commercialization of low Earth orbit so NASA can focus resources on journeying to the Moon and Mars. “Aviation started out as government-funded and now is commonplace for the public. I look forward to seeing how that evolution progresses in low Earth orbit.” His advice to the Artemis Generation is to consider the long-term impact of their actions and decisions. “What looks great on paper may not be a great solution when you have to send 10 commands just to do one task, or when the crew has to put their hand deep into the spacecraft to actuate a manual override,” he said. “The decisions you make today will be felt by operations in the future.” View the full article

This Landsat image uses infrared wavelengths to depict vegetation.Credit: U.S. Geological Survey The 30-acre pear orchard in the Sacramento-San Joaquin River Delta has been in Brett Baker’s family since the end of the Gold Rush. After six generations, though, California’s most precious resource is no longer gold – it’s water. And most of the state’s freshwater is in the delta. Landowners there are required to report their water use, but methods for monitoring were expensive and inaccurate. Recently, however, a platform called OpenET, created by NASA, the U.S. Geological Survey (USGS), and other partners, has introduced the ability to calculate the total amount of water transferred from the surface to the atmosphere through evapotranspiration. This is a key measure of the water that’s actually being removed from a local water system. It’s calculated based on imagery from Landsat and other satellites. “It’s good public policy to start with a measure everyone can agree upon,” Baker said. OpenET is only one of the latest uses researchers and businesses continue finding for Landsat over 50 years after the program started collecting continuous imagery of Earth’s surface. NASA has built and launched all nine of the satellites before handing them over to USGS, which manages the program. Some of the most pressing questions people ask about Earth are about the food it’s producing. Agriculture and adjacent industries are among the heaviest users of Earth-imaging data, which can help assess crop health and predict yields. The latest Landsat satellite, Landsat 9, went into orbit in fall of 2021. NASA and the USGS are already developing options for the next iteration of Landsat, currently known as Landsat Next.Credit: NASA Even in this well-established niche, though, new capabilities continue to emerge. One up-and-coming company is using Landsat to validate sustainable farming practices by measuring carbon stored in the ground, which can be detected in the reflectance rate in certain wavelengths. This is how Perennial Inc. is enabling emerging markets for carbon credits, through which farmers get paid for maximizing their land’s storage of carbon. The company is also discovering interest among food companies that want to reduce their environmental impact by choosing eco-conscious suppliers, as well as companies in the fertilizer, farm equipment, and agricultural lending businesses. Landsat also enables countless map-based apps, studies of changes in Earth’s surface cover over half a century, and so much more.

Earlier this year, the agency commissioned design studies from the NASA community and eight selected industry teams on how to return Martian samples to Earth in the 2030s while lowering the cost, risk, and mission complexity. The new strategy review team will assess 11 studies conducted by industry, a team across NASA centers, the agency’s Jet Propulsion Laboratory in Southern California, and the Johns Hopkins Applied Physics Laboratory. The team will recommend to NASA a primary architecture for the campaign, including associated cost and schedule estimates. “Mars Sample Return will require a diversity of opinions and ideas to do something we’ve never done before: launch a rocket off another planet and safely return samples to Earth from more than 33 million miles away,” said NASA Administrator Bill Nelson. “It is critical that Mars Sample Return is done in a cost-effective and efficient way, and we look forward to learning the recommendations from the strategy review team to achieve our goals for the benefit of humanity.” Returning samples from Mars has been a major long-term goal of international planetary exploration for more than three decades, and the Mars Sample Return Program is jointly planned with ESA (European Space Agency). NASA’s Perseverance rover is collecting compelling science samples that will help scientists understand the geological history of Mars, the evolution of its climate, and potential hazards for future human explorers. Retrieval of the samples also will help NASA’s search for signs of ancient life. The team’s report is anticipated by the end of 2024 and will examine options for a complete mission design, which may be a composite of multiple studied design elements. The team will not recommend specific acquisition strategies or partners. The strategy review team has been chartered under a task to the Cornell Technical Services contract. The team may request input from a NASA analysis team that consists of government employees and expert consultants. The analysis team also will provide programmatic input such as a cost and schedule assessment of the architecture recommended by the strategy review team.

  25. 3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA operations engineer Daniel Velasquez, left, is reviewing the Mobile Vertipad Sensor Package system as part of the Air Mobility Pathways test project at NASA’s Armstrong Flight Research Center in Edwards, California, on Oct. 17, 2023.NASA/Steve Freeman Lee esta historia en Español aquí. Born and raised in Peru, Daniel Velasquez moved to the United States when was 10 years old. While that decision was a big transition for his family, it also created many opportunities for him. Now Velasquez is an operations engineer for NASA’s Air Mobility Pathfinders project at NASA’s Armstrong Flight Research Center in Edwards, California. Velasquez develops flight test plans for electric vertical take-off and landing (eVTOL) aircraft, specifically testing how they perform during various phases of flight, such as taxi, takeoff, cruise, approach, and landing. He was drawn to NASA Armstrong because of the legacy in advancing flight research and the connection to the Space Shuttle program. “Being part of a center with such a rich history in supporting space missions and cutting-edge aeronautics was a major motivation for me,” Velasquez said. “One of the biggest highlights of my career has been the opportunity to meet (virtually) and collaborate with an astronaut on a possible future NASA project.” Daniel Velasquez stands next to the main entrance sign at NASA’s Armstrong Flight Research Center in Edwards, California, in 2022.Daniel Velasquez Velasquez is incredibly proud of his Latino background because of its rich culture, strong sense of community and connection to his parents. “My parents are my biggest inspiration. They sacrificed so much to ensure my siblings and I could succeed, leaving behind the comfort of their home and family in Peru to give us better opportunities,” Velasquez said. “Their hard work and dedication motivate me every day. Everything I do is to honor their sacrifices and show them that their efforts weren’t wasted. I owe all my success to them.” Velasquez began his career at NASA in 2021 as an intern through the Pathways Internship Program while he was studying aerospace engineering at Rutgers University in New Brunswick, New Jersey. Through that program, he learned about eVTOL modeling software called NASA Design and Analysis of Rotorcraft to create a help guide for other NASA engineers to reference when they worked with the software. At the same time, he is also a staff sergeant in the U.S Army Reserves and responsible for overseeing the training and development of junior soldiers during monthly assemblies. He plans, creates, and presents classes for soldiers to stay up-to-date and refine their skills while supervising practical exercises, after action reviews, and gathering lessons learned during trainings. Daniel Velasquez graduated in 2023 from Rutgers University in New Jersey while he was an intern at NASA. Behind him is the New York City skyline.Daniel Velasquez “This job is different than what I do day-to-day at NASA, but it has helped me become a more outspoken individual,” he said. “Being able to converse with a variety of people and be able to do it well is a skill that I acquired and refined while serving my country.” Velasquez said he never imagined working for NASA as it was something he had only seen in movies and on television, but he is so proud to be working for the agency after all the hard work and sacrifices he made that lead him to this point. “I am incredibly proud to work every day with some of the most motivated and dedicated individuals in the industry.” Share Details Last Updated Oct 16, 2024 Related TermsArmstrong Flight Research CenterAir Mobility Pathfinders projectGeneralHispanic Heritage MonthPeople of ArmstrongPeople of NASA Explore More 4 min read Sacrificio y Éxito: Ingeniero de la NASA honra sus orígenes familiares Article 23 mins ago 6 min read Christine Knudson Uses Earthly Experience to Study Martian Geology Geologist Christine Knudson works with the Curiosity rover to explore Mars — from about 250… Article 7 hours ago 7 min read What is a Coral Reef?
