New images taken from space show how dust on and around InSight is changing over time — information that can help scientists learn more about the Red Planet.

NASA’s Mars Reconnaissance Orbiter (MRO) caught a glimpse of the agency’s retired InSight lander recently, documenting the accumulation of dust on the spacecraft’s solar panels. In the new image taken Oct. 23 by MRO’s High-Resolution Imaging Science Experiment (HiRISE) camera, InSight’s solar panels have acquired the same reddish-brown hue as the rest of the planet.

After touching down in November 2018, the lander was the first to detect the Red Planet’s marsquakes, revealing details of the crust, mantle, and core in the process. Over the four years that the spacecraft collected science, engineers at NASA’s Jet Propulsion Laboratory in Southern California, which led the mission, used images from InSight’s cameras and MRO’s HiRISE to estimate how much dust was settling on the stationary lander’s solar panels, since dust affected its ability to generate power.

NASA retired InSight in December 2022, after the lander ran out of power and stopped communicating with Earth during its extended mission. But engineers continued listening for radio signals from the lander in case wind cleared enough dust from the spacecraft’s solar panels for its batteries to recharge. Having detected no changes over the past two years, NASA will stop listening for InSight at the end of this year.

NASA’s InSight Mars lander acquires the same reddish-brown hue as the rest of the planet in a set of images from 2018 to 2024 that were captured by the agency’s Mars Reconnaissance Orbiter using its High-Resolution Imagine Science Experiment (HiRISE) camera.

Scientists requested the recent HiRISE image as a farewell to InSight, as well as to monitor how its landing site has changed over time.

“Even though we’re no longer hearing from InSight, it’s still teaching us about Mars,” said science team member Ingrid Daubar of Brown University in Providence, Rhode Island. “By monitoring how much dust collects on the surface — and how much gets vacuumed away by wind and dust devils — we learn more about the wind, dust cycle, and other processes that shape the planet.”

Dust Devils and Craters

Dust is a driving force across Mars, shaping both the atmosphere and landscape. Studying it helps scientists understand the planet and engineers prepare for future missions (solar-powered and otherwise), since dust can get into sensitive mechanical parts.

When InSight was still active, scientists matched MRO images of dust devil tracks winding across the landscape with data from the lander’s wind sensors, finding these whirling weather phenomena subside in the winter and pick up again in the summer.

The imagery also helped with the study of meteoroid impacts on the Martian surface. The more craters a region has, the older the surface there is. (This isn’t the case with Earth’s surface, which is constantly recycled as tectonic plates slide over one another.) The marks around these craters fade with time. Understanding how fast dust covers them helps to ascertain a crater’s age.

Another way to estimate how quickly craters fade has been studying the ring of blast marks left by InSight’s retrorocket thrusters during landing. Much more prominent in 2018, those dark marks are now returning to the red-brown color of the surrounding terrain.

HiRISE has captured many other spacecraft images, including those of NASA’s Perseverance and Curiosity rovers, which are still exploring Mars, as well as inactive missions, like the Spirit and Opportunity rovers and the Phoenix lander.

“It feels a little bittersweet to look at InSight now. It was a successful mission that produced lots of great science. Of course, it would have been nice if it kept going forever, but we knew that wouldn’t happen,” Daubar said.

More About MRO and InSight

The University of Arizona, in Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp., in Boulder, Colorado. A division of Caltech in Pasadena, California, JPL manages the MRO project and managed InSight for NASA’s Science Mission Directorate, Washington.

The InSight mission was part of NASA’s Discovery Program, managed by the agency’s Marshall Space Flight Center in Huntsville, Alabama. Lockheed Martin Space in Denver built the InSight spacecraft, including its cruise stage and lander, and supported spacecraft operations for the mission.

A number of European partners, including France’s Centre National d’Études Spatiales (CNES) and the German Aerospace Center (DLR), supported the InSight mission. CNES provided the Seismic Experiment for Interior Structure (SEIS) instrument to NASA, with the principal investigator at IPGP (Institut de Physique du Globe de Paris). Significant contributions for SEIS came from IPGP; the Max Planck Institute for Solar System Research (MPS) in Germany; the Swiss Federal Institute of Technology (ETH Zurich) in Switzerland; Imperial College London and Oxford University in the United Kingdom; and JPL. DLR provided the Heat Flow and Physical Properties Package (HP3) instrument, with significant contributions from the Space Research Center (CBK) of the Polish Academy of Sciences and Astronika in Poland. Spain’s Centro de Astrobiología (CAB) supplied the temperature and wind sensors.

      A rendering of Firefly’s Blue Ghost lunar lander and a rover developed for the company’s third mission to the Moon as part of NASA’s CLPS (Commercial Lunar Payload Services) initiative.Credit: Firefly Aerospace NASA continues to advance its campaign to explore more of the Moon than ever before, awarding Firefly Aerospace $179 million to deliver six experiments to the lunar surface. This fourth task order for Firefly will target landing in the Gruithuisen Domes on the near side of the Moon in 2028.
      As part of the agency’s broader Artemis campaign, Firefly will deliver a group of science experiments and technology demonstrations under NASA’s CLPS initiative, or Commercial Lunar Payload Services, to these lunar domes, an area of ancient lava flows, to better understand planetary processes and evolution. Through CLPS, NASA is furthering our understanding of the Moon’s environment and helping prepare for future human missions to the lunar surface, as part of the agency’s Moon to Mars exploration approach. 
      “The CLPS initiative carries out U.S. scientific and technical studies on the surface of the Moon by robot explorers. As NASA prepares for future human exploration of the Moon, the CLPS initiative continues to support a growing lunar economy with American companies,” said Joel Kearns, deputy associate administrator for exploration, Science Mission Directorate, NASA Headquarters in Washington. “Understanding the formation of the Gruithuisen Domes, as well as the ancient lava flows surrounding the landing site, will help the U.S. answer important questions about the lunar surface.”
      Firefly’s first lunar delivery is scheduled to launch no earlier than mid-January 2025 and will land near a volcanic feature called Mons Latreille within Mare Crisium, on the northeast quadrant of the Moon’s near side. Firefly’s second lunar mission includes two task orders: a lunar orbit drop-off of a satellite combined with a delivery to the lunar surface on the far side and a delivery of a lunar orbital calibration source, scheduled in 2026.
      This new delivery in 2028 will send payloads to the Gruithuisen Domes and the nearby Sinus Viscositatus. The Gruithuisen Domes have long been suspected to be formed by a magma rich in silica, similar in composition to granite. Granitic rocks form easily on Earth due to plate tectonics and oceans of water. The Moon lacks these key ingredients, so lunar scientists have been left to wonder how these domes formed and evolved over time. For the first time, as part of this task order, NASA also has contracted to provide “mobility,” or roving, for some of the scientific instruments on the lunar surface after landing. This will enable new types of U.S. scientific investigations from CLPS.
      “Firefly will deliver six instruments to understand the landing site and surrounding vicinity,” said Chris Culbert, manager of the CLPS initiative at NASA’s Johnson Space Center in Houston. “These instruments will study geologic processes and lunar regolith, test solar cells, and characterize the neutron radiation environment, supplying invaluable information as NASA works to establish a long-term presence on the Moon.”
      The instruments, collectively expected to be about 215 pounds (97 kilograms) in mass, include: 
      Lunar Vulkan Imaging and Spectroscopy Explorer, which consists of two stationary and three mobile instruments, will study rocks and regoliths on the summit of one of the domes to determine their origin and better understand geologic processes of early planetary bodies. The principal investigator is Dr. Kerri Donaldson Hanna of the University of Central Florida, Orlando. Heimdall is a flexible camera system that will be used to take pictures of the landing site from above the horizon to the ground directly below the lander. The principal investigator is Dr. R. Aileen Yingst of the Planetary Science Institute, Tucson, Arizona. Sample Acquisition, Morphology Filtering, and Probing of Lunar Regolith is a robotic arm that will collect samples of lunar regolith and use a robotic scoop to filter and isolate particles of different sizes. The sampling technology will use a flight spare from the Mars Exploration Rover project. The principal investigator is Sean Dougherty of Maxar Technologies, Westminster, Colorado. Low-frequency Radio Observations from the Near Side Lunar Surface is designed to observe the Moon’s surface environment in radio frequencies, to determine whether natural and human-generated activity near the surface interferes with science. The project is headed up by Natchimuthuk Gopalswamy of NASA’s Goddard Space Flight Center in Greenbelt, Maryland.  Photovoltaic Investigation on the Lunar Surface will carry a set of the latest solar cells for a technology demonstration of light-to-electricity power conversion for future missions. The experiment will also collect data on the electrical charging environment of the lunar surface using a small array of solar cells. The principal investigator is Jeremiah McNatt from NASA’s Glenn Research Center in Cleveland. Neutron Measurements at the Lunar Surface is a neutron spectrometer that will characterize the surface neutron radiation environment, monitor hydrogen, and provide constraints on elemental composition. The principal investigator is Dr. Heidi Haviland of NASA’s Marshall Spaceflight Center in Huntsville, Alabama. Through the CLPS initiative, NASA purchases lunar landing and surface operations services from American companies. The agency uses CLPS to send scientific instruments and technology demonstrations to advance capabilities for science, exploration, or commercial development of the Moon. By supporting a robust cadence of lunar deliveries, NASA will continue to enable a growing lunar economy while leveraging the entrepreneurial innovation of the commercial space industry. Two upcoming CLPS flights scheduled to launch in early 2025 will deliver NASA payloads to the Moon’s near side and south polar region, respectively.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      LISTER (Lunar Instrumentation for Subsurface Thermal Exploration with Rapidity) is one of 10 payloads flying aboard the next delivery for NASA’s CLPS (Commercial Lunar Payload Services) initiative. The instrument is equipped with a drilling system and thermal probe designed to dig into the lunar surface. Photo courtesy: Firefly Aerospace Earth’s nearest neighboring body in the solar system is its Moon, yet to date humans have physically explored just 5% of its surface. It wasn’t until 2023 – building on Apollo-era data and more detailed studies made in 2011-2012 by NASA’s automated GRAIL (Gravity Recovery and Interior Laboratory) mission – that researchers conclusively determined that the Moon has a liquid outer core surrounding a solid inner core.
      As NASA and its industry partners plan for continued exploration of the Moon under Artemis in preparation for future long-duration missions to Mars, improving our understanding of Earth’s 4.5-billion-year-old Moon will help teams of researchers and astronauts find the safest ways to study and live and work on the lunar surface.
      That improved understanding is  the primary goal of a state-of-the-art science instrument called LISTER (Lunar Instrumentation for Subsurface Thermal Exploration with Rapidity), one of 10 NASA payloads flying aboard the next delivery for the agency’s CLPS (Commercial Lunar Payload Services) initiative and set to be carried to the surface by Firefly Aerospace’s Blue Ghost 1 lunar lander.
      Developed jointly by Texas Tech University in Lubbock and Honeybee Robotics of Altadena, California, LISTER will measure the flow of heat from the Moon’s interior. Its sophisticated pneumatic drill will penetrate to a depth of three meters into the dusty lunar regolith. Every half-meter it descends, the drilling system will pause and extend a custom-built thermal probe into the lunar regolith. LISTER will measure two different aspects of heat flow: thermal gradient, or the changes in temperature at various depths, and thermal conductivity, or the subsurface material’s ability to let heat pass through it.
      “By making similar measurements at multiple locations on the lunar surface, we can reconstruct the thermal evolution of the Moon,” said Dr. Seiichi Nagihara, principal investigator for the mission and a geophysics professor at Texas Tech. “That will permit scientists to retrace the geological processes that shaped the Moon from its start as a ball of molten rock, which gradually cooled off by releasing its internal heat into space.”
      Demonstrating the drill’s effectiveness could lead to more innovative drilling capabilities, enabling future exploration of the Moon, Mars, and other celestial bodies.. The science collected by LISTER aims to contribute to our knowledge of lunar geology, improving our ability to establish a long-term presence on the Moon under the Artemis campaign.
      Under the CLPS model, NASA is investing in commercial delivery services to the Moon to enable industry growth and support long-term lunar exploration. As a primary customer for CLPS deliveries, NASA aims to be one of many customers on future flights. NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the development of seven of the 10 CLPS payloads carried on Firefly’s Blue Ghost lunar lander.

      This article is for students grades 5-8.
      The Sun is the star of our solar system. Its gravity holds Earth and our planetary neighbors in its orbit. At 865,000 miles (1.4 million km) in diameter, it’s the largest object in our solar system. On Earth, its influence is felt in our weather, seasons, climate, and more. Let’s learn about our dynamic star and its connections to life on Earth.
      What is the Sun, and what is it made of?
      The Sun is a yellow dwarf star. It is approximately 4.5 billion years old and is in its “main sequence” phase. This means it is partway through its lifecycle with a few billion more years ahead of it.
      The Sun is made of hydrogen and helium gases. At its core, hydrogen is fused to form helium. This nuclear reaction creates the Sun’s heat and light. That energy moves outward through the Sun’s radiative zone and convective zone. It then reaches the Sun’s visible surface and lower atmosphere, called the photosphere. Above the photosphere lies the chromosphere, which forms the Sun’s middle atmosphere, and beyond that is the corona, the Sun’s outermost atmosphere.
      The Sun is a yellow dwarf star with a complex series of layers and features.NASA What is the solar cycle?
      The Sun goes through a pattern of magnetic activity known as the solar cycle. During each cycle, the Sun experiences a very active period called “solar maximum” and a less active period called “solar minimum.”
      During solar maximum, increased magnetic activity creates sunspots. These appear as darker, cooler spots on the Sun’s surface. The more sunspots we can see, the more active the Sun is.
      The solar cycle begins at solar minimum, peaks at solar maximum, and then returns to solar minimum. This cycle is driven by the Sun’s magnetic polarity, which flips – north becomes south, and vice versa – every 11 years. It takes two cycles – or 22 years – to complete the full magnetic cycle where the poles return to their original positions.  
      The Sun’s level of magnetic activity changes throughout its 11-year solar cycle. During each cycle, the Sun experiences a less-active period called “solar minimum” (left) and a very active period called “solar maximum” (right).NASA Wait. The Sun’s magnetic poles can flip??
      Yes! Like Earth, the Sun has north and south magnetic poles. But unlike Earth, the Sun’s poles flip regularly. Each 11-year solar cycle is marked by the flipping of the Sun’s poles. The increased magnetic activity during solar maximum makes the north and south poles less defined. As the cycle moves back to solar minimum, the polarization of the poles returns – with flipped polarity.
      Unlike Earth, the Sun’s poles regularly flip with each 11-year solar cycle.NASA What is space weather?
      Space weather includes phenomena such as solar wind, solar storms, and solar flares. When space weather conditions are calm, there may be little noticeable effect on Earth. But when the Sun is more active, space weather has real impacts on Earth and in space.
      Let’s explore these phenomena and how they affect our planet.
      Periods of increased solar activity can cause noticeable effects on Earth and in space.NASA What is solar wind?
      Solar wind is a stream of charged particles that flow outward from the Sun’s corona. It extends far beyond the orbit of the planets in our solar system. When solar wind reaches Earth, its charged particles interact with Earth’s magnetic field. This causes colorful streams of moving light at Earth’s north and south poles called aurora.
      Earth’s magnetic field protects our planet from the charged solar particles of the solar wind.NASA What are solar storms, solar flares, and coronal mass ejections?
      The Sun’s magnetic fields are a tangle of constant motion. These fields twist and stretch to the point that they snap and reconnect. When this magnetic reconnection occurs, it releases a burst of energy that can cause a solar storm.
      Solar storms can include phenomena such as solar flares or coronal mass ejections. They happen more frequently around the solar maximum of the Sun’s cycle. A solar flare is an intense burst of light and energy from the Sun’s surface. Solar flares tend to happen near sunspots where the Sun’s magnetic fields are strongest. A coronal mass ejection is a massive cloud of material flowing outward from the Sun. These can occur on their own or along with solar flares.
      The Sun’s magnetic field is strongest near sunspots. These active regions of the Sun’s surface release energy in the form of solar flares and coronal mass ejections like these.NASA How do these phenomena affect Earth?
      When a solar storm erupts towards Earth, our atmosphere and magnetic field protect us from significant harm. However, some impacts are possible, both on Earth and in space. For example, strong solar storms can cause power outages and radio blackouts. GPS signals can be disrupted. Satellite electronics can be affected. And astronauts working outside of the International Space Station could be exposed to dangerous radiation. NASA monitors and forecasts space weather to protect the safety and health of astronauts and spacecraft.
      When charged particles from intense solar storms interact with Earth’s magnetic fields, colorful auroras like this one captured in Saskatchewan, Canada, can occur.NASA Learn more about the Sun
      NASA’s Parker Solar Probe launched in 2018 on the first-ever mission to fly into the Sun’s corona. Since its first pass through the corona in 2021, every orbit has brought it closer to the Sun. On Dec. 24, 2024, it makes the first of its three final, closest solar approaches of its primary mission. Test your knowledge with NASA’s new quiz, Kahoot! Parker Solar Probe trivia.

      Photographers at NASA capture the sunset on Tuesday, Jan. 30, 2024, near the headquarters building of the agency’s Kennedy Space Center in Florida.NASA/Ben Smegelsky As NASA’s Kennedy Space Center in Florida wraps up a year that will see more than 90 government, commercial, and private missions launch from Florida’s Space Coast, a look to 2025 shows the missions, partnerships, projects, and programs at the agency’s main launch site will continue innovating, inspiring, and pushing the boundaries of exploration for the benefit of humanity.
      “The next year promises to be another exciting one at Earth’s premier spaceport,” said Kennedy Center Director Janet Petro. “We have an amazing workforce, and when we join forces with industry and our other government partners, even the sky is no limit to what we can accomplish.”
      New Year, New Missions to Space Station
      NASA’s Commercial Crew Program (CCP), based out of Kennedy, and its commercial partner SpaceX plan two crew rotation missions to the International Space Station: NASA’s SpaceX Crew-10 and Crew-11. This also means the return of the Crew-9 mission and later Crew-10 during 2025. CCP continues working with Boeing toward NASA certification of the company’s Starliner system for future crew rotations to the orbiting laboratory.
      NASA’s SpaceX Crew-10 members stand between Falcon 9 first-stage boosters at SpaceX’s HangarX facility at NASA’s Kennedy Space Center in Florida. From left are Mission Specialist Kirill Peskov of Roscosmos, Mission Specialist Takuya Onishi of JAXA (Japan Aerospace Exploration Agency), along with NASA astronauts Commander Anne McClain and Pilot Nichole Ayers. SpaceX “Operations in 2025 are a testament to NASA’s workforce carefully planning and preparing to safely execute a vital string of missions that the agency can depend on,” said Dana Hutcherson, CCP deputy program manager. “This is the 25th year of crewed operations for the space station, and we know that with every launch, we are sustaining a critical national asset and enabling groundbreaking research.”
      NASA also plans several Commercial Resupply Services missions, utilizing SpaceX’s Dragon cargo spacecraft, Northrop Grumman’s Cygnus spacecraft, and the inaugural flight of Sierra Space’s cargo spaceplane, Dream Chaser.  The missions will ferry thousands of pounds of supplies, equipment, and science investigations to the crew aboard the orbiting laboratory from NASA Kennedy and nearby Cape Canaveral Space Force Station.
      The SpaceX Falcon 9 rocket carrying the Dragon spacecraft lifts off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida on Tuesday, Nov. 4, on the company’s 31st commercial resupply services mission for the agency to the International Space Station. Liftoff was at 9:29 p.m. EST. SpaceX In addition to the agency’s crewed flights, Axiom Space’s fourth crewed private spaceflight mission, Axiom Mission 4 – organized in collaboration with NASA through the International Space Station Program and operated by SpaceX – will launch to the orbital outpost.  
      Reestablishing Humanity’s Lunar Presence
      Preparations for NASA’s Artemis II test flight mission are ramping up, with all major components for the SLS (Space Launch System) hardware undergoing processing at Kennedy, including the twin solid rocket boosters and 212-foot-tall core stage. Teams with EGS (Exploration Ground Systems) will continue stacking the booster segments inside the spaceport’s VAB (Vehicle Assembly Building). Subsequent integration and testing of the rocket’s hardware and Orion spacecraft will continue not only for the Artemis II mission, but for Artemis III and IV. Technicians also continue building mobile launcher 2, which will serve as the launch and integration platform for the SLS Block 1B configuration starting with Artemis IV.
      Teams with NASA’s Exploration Ground Systems transport the agency’s 212-foot-tall SLS (Space Launch System) core stage into High Bay 2 at the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on Wednesday, Dec. 11, 2024. The one-of-a kind lifting beam is designed to lift the core stage from the transfer aisle to High Bay 2 where it will remain while teams stack the two solid rocket boosters on top of mobile launcher 1 for the SLS core stage.NASA/Kim Shiflett “Looking ahead to 2025, teams will embark on a transformative year as we integrate the flight hardware for Artemis II, while simultaneously developing the foundation for future Artemis missions that will reestablish humanity’s presence on the Moon,” said Shawn Quinn, EGS program manager.
      A key part of the Artemis campaign, NASA’s CLPS (Commercial Lunar Payload Services) initiative will continue leveraging commercial partnerships to quickly land scientific instruments and technology demonstrations on the Moon. Firefly Aerospace’s first lunar CLPS flight, Blue Ghost Mission 1, will carry 10 NASA science and technology instruments to the lunar surface, including the Electrodynamic Dust Shield, a technology built by Kennedy engineers. Intuitive Machines, meanwhile, will embark on its second CLPS flight to the Moon. Providing the first in-situ resource utilization demonstration on the lunar surface, IM-2 will carry the Polar Resources Ice Mining Experiment-1 (PRIME-1), which features The Regolith and Ice Drill for Exploring New Terrain from Honeybee Robotics, as well as the Mass Spectrometer Observing Lunar Operations built by Kennedy. Both flights are targeted to lift off from Kennedy’s Launch Complex 39A during the first quarter of 2025.
      As part of NASA’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign, Firefly Aerospace’s Blue Ghost Mission One lander will carry 10 NASA science and technology instruments to the Moon’s near side.Firefly Aerospace In development for Artemis IV and beyond, Gateway will be a critical platform for developing a sustained human presence beyond low Earth orbit. Deep Space Logistics (DSL) is the Gateway Program project office at Kennedy responsible for leading the development of a commercial supply chain in deep space. In 2025, DSL will continue developing the framework for the DSL-1 mission and working with commercial provider SpaceX to mature spacecraft design. Upcoming milestones include a system requirements review and preliminary design review to determine the program’s readiness to proceed with the detailed design phase supporting the agency’s Gateway Program and Artemis IV mission objectives.
      Science Missions Studying Our Solar System and Beyond
      NASA’s Launch Services Program (LSP), based at Kennedy, is working to launch three ambitious missions. Launching early in the year on a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California, SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) is a space telescope to survey the universe using visible and near-infrared light, observing more colors than ever before and allowing astronomers to piece together a three-dimensional map of the universe with stunning accuracy. Launching with SPHEREx, NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission will study how the mass and energy of the Sun’s corona transition into the solar wind.
      NASA’s SPHEREx space observatory was photographed at BAE Systems in Boulder, Colorado, in November 2024 after completing environmental testing. The spacecraft’s three concentric cones help direct heat and light away from the telescope and other components, keeping them cool. BAE Systems IMAP (Interstellar Mapping and Acceleration Probe), scheduled to launch from Cape Canaveral in late 2025, will help map out thethe heliosphere – the magnetic environment surrounding and protecting our solar system. Carrying 10 instruments to make its observations, the IMAP mission is targeting the L1 Lagrange Point, an area between Earth and the Sun that is easy for spacecraft to maintain orbit, along with two Sun observing rideshare missions – NASA’s Carruthers Geocorona Observatory and the National Oceanic and Atmospheric Administration’s SWFO-L1 (Space Weather Follow-On at L1). Also launching in late 2025 on a Falcon 9 from Vandenberg is the second of two identical satellites, Sentinel-6B, which will monitor global sea levels with unprecedented precision. Its predecessor, Sentinel-6 Michael Freilich, has been delivering crucial data since it launched in 2020, and Sentinel-6B will ensure the continuation of this mission through 2030.
      “Our missions launching next year will include groundbreaking technologies to help us learn more about the universe than ever before and provide new data for researchers that will have positive benefits here on Earth,” said LSP’s Deputy Program Manager Jenny Lyons.
      NASA’s ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers) identical dual spacecraft are inspected and processed on dollies in a high bay of the Astrotech Space Operations Facility near the agency’s Kennedy Space Center in Florida on Thursday, Aug. 22, 2024. As the first multi-spacecraft orbital science mission to Mars, ESCAPADE’s twin orbiters will take simultaneous observations from different locations around the planet and reveal the real-time response to space weather and how the Martian magnetosphere changes over time.NASA/Kim Shiflett The program’s support for small satellite missions next year includes several missions to monitor the Sun, collect climate data, and more. NASA’s ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers) mission to explore Mars’ magnetosphere will lift off from Cape Canaveral’s Launch Complex 36 on NASA’s inaugural flight of Blue Origin’s New Glenn rocket. Some of these small satellite missions are part of NASA’s CubeSat Launch Initiative, which offers the next generation of scientists, engineers, and technologists a unique opportunity to conduct scientific research and develop and demonstrate novel technologies in space.
      Building the Spaceport’s Future
      Teams expect a busy year of construction projects to accommodate new missions, hardware, and milestones. In preparation for Artemis IV, mobile launcher 2 construction and modifications in the VAB’s High Bays 3 and 4 for the larger SLS Block 1B configuration will ramp up. Teams also will upgrade the spaceport’s Converter Compressor Facility (CCF) to meet the helium needs of its commercial launch partners and the Artemis campaign, increasing efficiency, reliability, and speed of pumping helium to rockets. Upgrades to the CCF’s internal infrastructure are also part of Kennedy’s plan to earn the U.S. Green Building Council’s Leadership in Energy and Environmental Design certification, joining nine other Kennedy facilities in achieving that rating.
      Photographers at NASA capture the sunset on Tuesday, Jan. 30, 2024, near Vehicle Assembly Building at the agency’s Kennedy Space Center in Florida. The iconic Vehicle Assembly Building, currently used for assembly of NASA’s Space Launch System rocket for Artemis missions, remains the only building in which rockets were assembled that carried humans to the surface of another world. NASA/Ben Smegelsky “Kennedy’s spaceport will continue to see its launch cadence grow, and we have to meet our program and commercial partner needs in the most efficient way possible,” said Sasha Sims, deputy director of Kennedy’s Spaceport Integration and Services Directorate. “Process improvements and integrated approaches should improve the speed at which government and commercial construction takes place while also improving Kennedy’s infrastructure so that it’s robust, sustainable, and able to support America’s future in space.”
      Driving down acquisition costs, increasing competition, and using innovative contracting mechanisms for construction are just some of the initiatives to maximize efficiency and reliability in 2025. The center’s “Critical Day” policy prohibits certain types of work during launches requiring full flight range support but will no longer apply to commercial launches where minimal flight range support is required, training events, static fires, exercises, tests, rehearsals, nor other activities leading up to or supporting launches. This policy change is expected to create more flexibility and free up over 150 days annually for construction, maintenance, and other essential work needed to keep the spaceport running smoothly.
      Finally, Kennedy will continue carrying Apollo’s legacy through Artemis. Seeds that traveled aboard the Orion spacecraft during the Artemis I mission will be planted at the spaceport, honoring the legacy of the original Moon Trees that grew from seeds flown on Apollo 14. The Florida spaceport will become one of the select locations across the country where the “new generation” of Moon Trees will take root and provide living testimony to the agency’s continuing legacy of lunar exploration.
      “With so many missions and initiatives on the horizon, I’m looking forward to another banner year at Kennedy Space Center,” Petro said. “We truly are launching humanity’s future.”
