Marshall Team Members March in 9th Annual Huntsville Christmas Parade

By Celine Smith

Team members from NASA’s Marshall Space Flight Center came together to spread holiday cheer with thousands on Dec. 5 during the 9th annual Huntsville Christmas Parade.

The Marshall float displayed a test version of the RS-25 engine – the workhorse engine that powered the space shuttle for more than three decades and is now used to power NASA’s SLS (Space Launch System) rocket for Artemis missions. The engine was outfitted with a handmade Santa Claus sleigh full of Christmas presents, crafted by Marshall’s Model and Exhibits Shop.

Children wowed and cheered as the sleigh passed through the city streets. Marshall volunteers dressed in fun holiday gear walked alongside the float passing out candy and stickers to attendees.

The Marshall team was awarded third place for Best Float Design by the parade committee. Winning first place was the City of Huntsville Landscape Management, while second place went to the Ice Queen Alabama float.

“It’s amazing to see Huntsville’s growth through all the organizations that participated by making a float,” said Chad Emerson, grand marshal of the parade and managing director of Huntsville’s City Football Club.

The parade was presented by Bank Independent and hosted by radio station Mix 96.9, along with the VBC (Von Braun Center). This year, the parade’s theme was Christmas through the decades. More than 80 organizations decorated their floats to reflect Christmas in the past.

The parade had plenty of fun-filled activities for children in the VIP FunZone, sponsored by Lander’s McLarty Chevrolet. There, children took pictures with Santa Claus, met Elsa and Anna from Frozen, built gingerbread houses, and drank hot chocolate. The ticket also provided access to bleachers in the VBC’s Saturn Ballroom parking lot, where families could enjoy the parade. A donation of clothing for Kids to Love was all that was needed for tickers to the VIP FunZone.

Six Finalists Advance in NASA’s $3.5 Million Lunar Regolith Challenge

By Savannah Bullard

The stage is set for the finale of NASA’s Break the Ice Lunar Challenge.

Conceived in 2020, Break the Ice tasked innovators with creating robotic systems that can traverse the volatile terrain of the Lunar South Pole. These robots must be able to dig into the Moon’s regolith – the dusty, icy “dirt” that makes up the lunar surface – and transport it to a secondary location for in-situ resource utilization processing.

A Graphic of the Break the Ice Lunar Challenge Logo placed on a photo of the Moon.

If deployed on a NASA mission, these systems would operate in the permanently shadowed regions of the Moon, an area that receives no sunlight. These technologies must survive bitterly cold conditions and cannot rely on solar power regeneration. If successful, NASA can excavate the regolith from this area and use the resources derived from the materials, like frozen water, to aid astronauts living on the Moon.

“Our goal is to provide solutions to make living on the Moon a reality, and Break the Ice directly contributes to that mission,” said Denise Morris, program manager for NASA’s Centennial Challenges. “Excavating lunar regolith before humans arrive on the Moon will allow us to find uses for that material before they get there – if we could build a lunar habitat out of the regolith or extract the water for our astronauts to drink, that means less mass on our vehicles and less work for our crews.”

Phase 1 of the competition focused on designing systems that could achieve three components: excavation, travel, and delivery. Of the 31 teams who submitted eligible proposals, 13 won cash prizes ranging from $25,000 to $125,000.

Phase 2, Level 1 opened in June 2022. Consisting of Phase 1 winners and newcomers, 25 teams developed their initial designs into prototypes with technical reports, engineering designs, and test plans. Six months later, 13 U.S. semifinalists were named, each earning an equal share of $500,000. Two international teams were also recognized as semifinalists, though they were not eligible to receive monetary prizes from NASA.

In Phase 2, Level 2, the finalist pool comprised of garage inventors, academics, industry professionals, and hobbyists from 11 U.S. states, the Netherlands, and India. Nine of these teams attempted a 15-day demonstration trial at their own testing sites to prove the capabilities of their prototypes. The teams live-streamed the tests and took turns hosting representatives from Centennial Challenges for in-person observations.

“What impresses me the most with this batch of competitors is their innate ability to each find unique ways to approach the solution,” said Break the Ice Challenge Manager Naveen Vetcha, who supports Centennial Challenges through Jacobs Space Exploration Group. “Each site visit provided our subject matter experts with new ways to think about this technology and operations, and some of these teams expanded our expectations for how to bridge this technology gap.”

The Phase 2, Level 2 winning teams are:

  • 1st place ($300,000): Starpath Robotics (San Francisco, California)
  • 2nd place ($200,000): Terra Engineering (Gardena, California)
  • 3rd place ($125,000): The Ice Diggers (Golden, Colorado)

Three teams finished as runners up ($75,000 each):

  • Cislune Excavators (Los Angeles, California)
  • Space Trajectory (Brookings, South Dakota)
  • MTU Planetary Surface Technology Development Lab (Houghton, Michigan)

In this last round of competitions, scheduled to take place in the spring of 2024, the above winners will bring their prototypes to a NASA-designated test facility for a series of head-to-head matchups. Expected testing includes excavation under reduced gravity – using gravity off-loading – and transportation over complex terrain, including rocks, craters, slopes, turns, and loose granular soil.

“Bringing the competitors to one central location is the best way to end a challenge like Break the Ice because it provides us with an opportunity to observe and test their designs in a common relevant environment,” said Mark Hilburger, a senior research engineer in the Space Technology Exploration Directorate at NASA’s Langley Research Center and principal technologist for Break the Ice. “These technologies must be thoroughly tested to survive on the Moon, so a test opportunity like this helps the teams prove if their prototypes are up to the task.”

This final round of competition will offer up to $1.5 million in cash prizes, split between first place ($1 million) and second place ($500,000). NASA will also award opportunities for teams to test their concepts at one of the agency’s Thermal Vacuum Chambers, which can simulate the temperature and atmospheric pressure conditions at the Lunar South Pole.

The Break the Ice Lunar Challenge is a NASA Centennial Challenge led by the agency’s Marshall Space Flight Center with support from NASA’s Kennedy Space Center. Centennial Challenges are part of the Prizes, Challenges, and Crowdsourcing program led by NASA’s Space Technology Mission Directorate and managed at Marshall. Ensemble Consultancy supports the management of competitors for this challenge.

NASA Continues Progress on Artemis III Rocket Adapter with Key Joint Installation

Engineers and technicians at NASA’s Marshall Space Flight Center recently installed a key component called the frangible joint assembly onto the adapter that connects the core stage to the upper part of NASA’s SLS (Space Launch System) rocket.

The cone-shaped launch vehicle stage adapter, seen in yellow, is in a production area.

The cone-shaped stage adapter, called the launch vehicle stage adapter, will be part of the SLS mega rocket that will power NASA’s Artemis III mission to the Moon. The frangible joint sits atop the adapter and operates as a separation mechanism. The frangible joint is designed to break apart upon command, allowing the upper part of the rocket, NASA’s Orion spacecraft, and the crew inside Orion to quickly separate from the SLS core stage and adapter.

Frangible joint assemblies are widely used across the space industry in a variety of crewed and uncrewed spacecraft to efficiently separate fairings or stages during launch, during ascent, in orbit and during payload deployment. The stage adapter used for Artemis III is set to be the last of its kind as SLS evolves into a larger and more powerful configuration for future Artemis missions, beginning with Artemis IV. The adapter is fully assembled at Marshall by NASA and lead contractor Teledyne Brown, which is also based in Huntsville. Marshall manages the SLS Program.

NASA Tests In-Flight Capability of Artemis Moon Rocket Engine

NASA conducted the third RS-25 engine hot fire in a critical 12-test certification series Nov. 29, demonstrating a key capability necessary for flight of the SLS (Space Launch System) rocket during Artemis missions to the Moon and beyond.

NASA is conducting the series of tests to certify new manufacturing processes for producing RS-25 engines for future deep space missions, beginning with Artemis V. Aerojet Rocketdyne, an L3Harris Technologies Company and lead engines contractor for the SLS rocket, is incorporating new manufacturing techniques and processes, such as 3D printing, in production of new RS-25 engines.

Crews gimbaled, or pivoted, the RS-25 engine around a central point during the almost 11-minute (650 seconds) hot fire on the Fred Haise Test Stand at NASA’s Stennis Space Center. The gimbaling technique is used to control and stabilize SLS as it reaches orbit.

During the Nov. 29 test, operators also pushed the engine beyond any parameters it might experience during flight to provide a margin of operational safety. The 650-second test exceeded the 500 seconds RS-25 engines must operate to help power SLS to space. The RS-25 engine also was fired to 113% power level, exceeding the 111% level needed to lift SLS to orbit.

The ongoing series will stretch into 2024 as NASA continues its mission to return humans to the lunar surface to establish a long-term presence for scientific discovery and to prepare for human missions to Mars.

Four RS-25 engines fire simultaneously to generate a combined 1.6 million pounds of thrust at launch and 2 million pounds of thrust during ascent to help power each SLS flight. NASA and Aerojet Rocketdyne modified 16 holdover space shuttle main engines, all proven flightworthy at NASA Stennis, for Artemis missions I through IV.

Every new RS-25 engine that will help power SLS also will be tested at NASA Stennis. RS-25 tests at the site are conducted by a combined team of NASA, Aerojet Rocketdyne, and Syncom Space Services operators. Syncom Space Services is the prime contractor for Stennis facilities and operations.

Chandra Catches Spider Pulsars Destroying Nearby Stars

A group of dead stars known as “spider pulsars” are obliterating companion stars within their reach. Data from NASA’s Chandra X-ray Observatory of the globular cluster Omega Centauri is helping astronomers understand how these spider pulsars prey on their stellar companions.

A pulsar is the spinning dense core that remains after a massive star collapses into itself to form a neutron star. Rapidly rotating neutron stars can produce beams of radiation. Like a rotating lighthouse beam, the radiation can be observed as a powerful, pulsing source of radiation, or pulsar. Some pulsars spin around dozens to hundreds of times per second, and these are known as millisecond pulsars.

A cluster brimming with millions of stars glistens like an iridescent opal in this image from NASA's Spitzer Space Telescope. Called Omega Centauri, the sparkling orb of stars is like a miniature galaxy. It is the biggest and brightest of the 150 or so similar objects, called globular clusters, that orbit around the outside of our Milky Way galaxy. Stargazers at southern latitudes can spot the stellar gem with the naked eye in the constellation Centaurus. Globular clusters are some of the oldest objects in our universe. Their stars are over 12 billion years old, and, in most cases, formed all at once when the universe was just a toddler. Omega Centauri is unusual in that its stars are of different ages and possess varying levels of metals, or elements heavier than boron. Astronomers say this points to a different origin for Omega Centauri than other globular clusters: they think it might be the core of a dwarf galaxy that was ripped apart and absorbed by our Milky Way long ago. In this new view of Omega Centauri, Spitzer's infrared observations have been combined with visible-light data from the National Science Foundation's Blanco 4-meter telescope at Cerro Tololo Inter-American Observatory in Chile. Visible-light data with a wavelength of .55 microns is colored blue, 3.6-micron infrared light captured by Spitzer's infrared array camera is colored green and 24-micron infrared light taken by Spitzer's multiband imaging photometer is colored red. Where green and red overlap, the color yellow appears. Thus, the yellow and red dots are stars revealed by Spitzer. These stars, called red giants, are more evolved, larger and dustier. The stars that appear blue were spotted in both visible and 3.6-micron-, or near-, infrared light. They are less evolved, like our own sun. Some of the red spots in the picture are distant galaxies beyond our own.

Spider pulsars are a special class of millisecond pulsars, and get their name for the damage they inflict on small companion stars in orbit around them. Through winds of energetic particles streaming out from the spider pulsars, the outer layers of the pulsar’s companion stars are methodically stripped away.

Astronomers recently discovered 18 millisecond pulsars in Omega Centauri located about 17,700 light-years from Earth – using the Parkes and MeerKAT radio telescopes. A pair of astronomers from the University of Alberta in Canada then looked at Chandra data of Omega Centauri to see if any of the millisecond pulsars give off X-rays.

They found 11 millisecond pulsars emitting X-rays, and five of those were spider pulsars concentrated near the center of Omega Centauri. The researchers next combined the data of Omega Centauri with Chandra observations of 26 spider pulsars in 12 other globular clusters.

There are two varieties of spider pulsars based on the size of the star being destroyed. “Redback” spider pulsars are damaging companion stars weighing between a tenth and a half the mass of the Sun. Meanwhile, the “black widow” spider pulsars are damaging companion stars with less than 5 percent of the Sun’s mass.

The team found a clear difference between the two classes of spider pulsars, with the redbacks being brighter in X-rays than the black widows, confirming previous work. The team is the first to show a general correlation between X-ray brightness and companion mass for spider pulsars, with pulsars that produce more X-rays being paired with more massive companions. This gives clear evidence that the mass of the companion to spider pulsars influences the X-ray dose the star receives.

The X-rays detected by Chandra are mainly thought to be generated when the winds of particles flowing away from the pulsars collide with winds of matter blowing away from the companion stars and produce shock waves, similar to those produced by supersonic aircraft.

A close-up image of Omega Centauri, in X-ray & optical light, shows the locations of some of the spider pulsars. Spider pulsars are a special class of millisecond pulsars, and get their name for the damage they inflict on small companion stars in orbit around them.

Spider pulsars are typically separated from their companions by only about one to 14 times the distance between the Earth and Moon. This close proximity – cosmically speaking – causes the energetic particles from the pulsars to be particularly damaging to their companion stars.

This finding agrees with theoretical models that scientists have developed. Because more massive stars produce a denser wind of particles, there is a stronger shock – producing brighter X-rays – when their wind collides with the particles from the pulsar. The proximity of the companion stars to their pulsars means the X-rays can cause significant damage to the stars, along with the pulsar’s wind.

Chandra’s sharp X-ray vision is crucial for studying millisecond pulsars in globular clusters because they often contain large numbers of X-ray sources in a small part of the sky, making it difficult to distinguish sources from each other. Several of the millisecond pulsars in Omega Centauri have other, unrelated X-ray sources only a few arc seconds away. (One arc second is the apparent size of a penny seen at a distance of 2.5 miles.)

The paper describing these results will be published in the December issue of the Monthly Notices of the Royal Astronomical Society, and a preprint of the accepted paper is available online. The authors of the paper are Jiaqi (Jake) Zhao and Craig Heinke, both from the University of Alberta in Canada.

Psyche Delivers First Images, Other Data

NASA’s Psyche spacecraft is on a roll. In the eight weeks since it left Earth on Oct. 13, the orbiter has performed one successful operation after another, powering on scientific instruments, streaming data toward home, and setting a deep-space record with its electric thrusters. The latest achievement: On Dec. 4, the mission turned on Psyche’s twin cameras and retrieved the first images – a milestone called “first light.”

Already 16 million miles from Earth, the spacecraft will arrive at its destination – the asteroid Psyche in the main asteroid belt between Mars and Jupiter – in 2029. The team wanted to test all of the science instruments early in the long journey to make sure they are working as intended, and to ensure there would be plenty of time to calibrate and adjust them as needed.

This mosaic was made from “first light” images acquired Dec. 4 by both of the cameras on NASA’s Psyche spacecraft. The star field lies in the constellation Pisces.

The imager instrument, which consists of a pair of identical cameras, captured a total of 68 images, all within a star field in the constellation Pisces. The imager team is using the data to verify proper commanding, telemetry analysis, and calibration of the images.

“These initial images are only a curtain-opener,” said Arizona State University’s Jim Bell, the Psyche imager instrument lead. “For the team that designed and operates this sophisticated instrument, first light is a thrill. We start checking out the cameras with star images like these, then in 2026 we’ll take test images of Mars during the spacecraft’s flyby. And finally, in 2029 we’ll get our most exciting images yet – of our target asteroid Psyche. We look forward to sharing all of these visuals with the public.”

The imager takes pictures through multiple color filters, all of which were tested in these initial observations. With the filters, the team will use photographs in wavelengths of light both visible and invisible to the human eye to help determine the composition of the metal-rich asteroid Psyche. The imager team will also use the data to create 3D maps of the asteroid to better understand its geology, which will give clues about Psyche’s history.

Earlier in the mission, in late October, the team powered on the magnetometer, which will provide crucial data to help determine how the asteroid formed. Evidence that the asteroid once had a magnetic field would be a strong indication that the body is a partial core of a planetesimal, a building block of an early planet. The information could help us better understand how our own planet formed.

Shortly after being powered on, the magnetometer gave scientists an unexpected gift: It detected a solar eruption, a common occurrence called a coronal mass ejection, where the Sun expels large quantities of magnetized plasma. Since then, the team has seen several of these events and will continue to monitor space weather as the spacecraft travels to the asteroid.

The good news is twofold. Data collected so far confirms that the magnetometer can precisely detect very small magnetic fields. It also confirms that the spacecraft is magnetically “quiet.” The electrical currents powering a probe of this size and complexity have the potential to generate magnetic fields that could interfere with science detections. Because Earth has its own powerful magnetic field, scientists obtained a much better measurement of the spacecraft magnetic field once it was in space.

On Nov. 8, amid all the work with the science instruments, the team fired up two of the four electric propulsion thrusters, setting a record: the first-ever use of Hall-effect thrusters in deep space. Until now, they’d been used only on spacecraft going as far as lunar orbit. By expelling charged atoms, or ions, of xenon gas, the ultra-efficient thrusters will propel the spacecraft to the asteroid (a 2.2-billion-mile journey) and help it maneuver in orbit.

Less than a week later, on Nov. 14, the technology demonstration built into the spacecraft, an experiment called Deep Space Optical Communications, or DSOC, set its own record. DSOC achieved first light by sending and receiving optical data from far beyond the Moon. The instrument beamed a near-infrared laser encoded with test data from nearly 10 million miles away – the farthest-ever demonstration of optical communications.

The Psyche team has also successfully powered on the gamma-ray detecting component of its third science instrument, the gamma-ray and neutron spectrometer. Next, the instrument’s neutron-detecting sensors will be turned on the week of Dec. 11. Together those capabilities will help the team determine the chemical elements that make up the asteroid’s surface material.

Arizona State University leads the Psyche mission. A division of Caltech, NASA’s JPL (Jet Propulsion Laboratory) is responsible for the mission’s overall management, system engineering, integration and test, and mission operations. Maxar Technologies in Palo Alto, California, provided the high-power solar electric propulsion spacecraft chassis. Arizona State leads the operations of the imager instrument, working in collaboration with Malin Space Science Systems in San Diego on the design, fabrication, and testing of the cameras.

JPL manages DSOC for the Technology Demonstration Missions program within NASA’s Space Technology Mission Directorate and the Space Communications and Navigation program within the Space Operations Mission Directorate.

Psyche is the 14th mission selected as part of NASA’s Discovery Program, managed by the agency’s Marshall Space Flight Center. NASA’s Launch Services Program, based at Kennedy, managed the launch service.

For safety and mission success, the landers and other equipment in development for NASA’s Artemis campaign must work reliably in the harshest of environments.
      The Hub for Innovative Thermal Technology Maturation and Prototyping (HI-TTeMP) lab at NASA’s Marshall Space Flight Center in Huntsville, Alabama, provides engineers with thermal analysis of materials that may be a prototype or in an early developmental stage using a vacuum chamber, back left, and a conduction chamber, right. NASA/Ken Hall Engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, are currently testing how well prototype insulation for SpaceX’s Starship HLS will insulate interior environments, including propellant storage tanks and the crew cabin. Starship HLS will land astronauts on the lunar surface during Artemis III and Artemis IV.
      Marshall’s Hub for Innovative Thermal Technology Maturation and Prototyping (HI-TTeMP) laboratory provides the resources and tools for an early, quick-check evaluation of insulation materials destined for Artemis deep space missions.
      “Marshall’s HI-TTeMP lab gives us a key testing capability to help determine how well the current materials being designed for vehicles like SpaceX’s orbital propellant storage depot and Starship HLS, will insulate the liquid oxygen and methane propellants,” said HLS chief engineer Rene Ortega. “By using this lab and the expertise provided by the thermal engineers at Marshall, we are gaining valuable feedback earlier in the design and development process that will provide additional information before qualifying hardware for deep space missions.”
      A peek inside the conductive test chamber at NASA Marshall’s HI-TTeMP lab where thermal engineers design, set up, execute, and analyze materials destined for deep space to better understand how they will perform in the cold near-vacuum of space. NASA/Ken Hall On the Moon, spaceflight hardware like Starship HLS will face extreme temperatures. On the Moon’s south pole during lunar night, temperatures can plummet to -370 degrees Fahrenheit (-223 degrees Celsius). Elsewhere in deep space temperatures can range from roughly 250 degrees Fahrenheit (120 degrees Celsius) in direct sunlight to just above absolute zero in the shadows.
      There are two primary means of managing thermal conditions: active and passive. Passive thermal controls include materials such as insulation, white paint, thermal blankets, and reflective metals. Engineers can also design operational controls, such as pointing thermally sensitive areas of a spacecraft away from direct sunlight, to help manage extreme thermal conditions. Active thermal control measures that could be used include radiators or cryogenic coolers.
      Engineers use two vacuum test chambers in the lab to simulate the heat transfer effects of the deep space environment and to evaluate the thermal properties of the materials. One chamber is used to understand radiant heat, which directly warms an object in its path, such as when heat from the Sun shines on it. The other test chamber evaluates conduction by isolating and measuring its heat transfer paths.
      NASA engineers working in the HI-TTeMP lab not only design, set up, and run tests, they also provide insight and expertise in thermal engineering to assist NASA’s industry partners, such as SpaceX and other organizations, in validating concepts and models, or suggesting changes to designs. The lab is able to rapidly test and evaluate design updates or iterations.
      NASA’s HLS Program, managed by NASA Marshall, is charged with safely landing astronauts on the Moon as part of Artemis. NASA has awarded contracts to SpaceX for landing services for Artemis III and IV and to Blue Origin for Artemis V. Both landing services providers plan to transfer super-cold propellant in space to send landers to the Moon with full tanks.
      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.

      NASA/JPL-Caltech This Oct. 4, 2017, illustration shows a hypothetical uneven ring of dust orbiting KIC 8462852, also known as Boyajian’s Star or Tabby’s Star. The star has experienced unusual dips in brightness over a matter of days, as well as much subtler but longer-term dimming trends. Scientists proposed several explanations for this unexpected behavior, ranging from Tabby’s Star swallowing a planet to alien “megastructures” harvesting the star’s energy. However, a study using NASA’s Spitzer and Swift missions as well as the Belgian AstroLAB IRIS observatory suggests that the cause of the dimming over long periods is likely an uneven dust cloud moving around the star.

      A 3D simulation showing the evolution of turbulent flows in the upper layers of the Sun. The more saturated and bright reds represent the most vigorous upward or downward twisting motions. Clear areas represent areas where there is only relatively slow up-flows, with very little twisting.NASA/Irina Kitiashvili and Timothy A. Sandstrom NASA supercomputers are shedding light on what causes some of the Sun’s most complex behaviors. Using data from the suite of active Sun-watching spacecraft currently observing the star at the heart of our solar system, researchers can explore solar dynamics like never before. 
      The animation shows the strength of the turbulent motions of the Sun’s inner layers as materials twist into its atmosphere, resembling a roiling pot of boiling water or a flurry of schooling fish sending material bubbling up to the surface or diving it further down below. 
      “Our simulations use what we call a realistic approach, which means we include as much as we know to-date about solar plasma to reproduce different phenomena observed with NASA space missions,” said Irina Kitiashvili, a scientist at NASA’s Ames Research Center in California’s Silicon Valley who helped lead the study. 
      Using modern computational capabilities, the team was able, for the first time to reproduce the fine structures of the subsurface layer observed with NASA’s Solar Dynamics Observatory.
      “Right now, we don’t have the computational capabilities to create realistic global models of the entire Sun due to the complexity,” said Kitiashvili. “Therefore, we create models of smaller areas or layers, which can show us structures of the solar surface and atmosphere – like shock waves or tornado-like features measuring only a few miles in size; that’s much finer detail than any one spacecraft can resolve.”
      Scientists seek to better understand the Sun and what phenomena drive the patterns of its activity. The connection and interactions between the Sun and Earth drive the seasons, ocean currents, weather, climate, radiation belts, auroras and many other phenomena. Space weather predictions are critical for exploration of space, supporting the spacecraft and astronauts of NASA’s Artemis campaign. Surveying this space environment is a vital part of understanding and mitigating astronaut exposure to space radiation and keeping our spacecraft and instruments safe.
      This has been a big year for our special star, studded with events like the annular eclipse, a total eclipse, and the Sun reaching its solar maximum period. In December 2024, NASA’s Parker Solar Probe mission – which is helping researchers to understand space weather right at the source – will make its closest-ever approach to the Sun and beat its own record of being the closest human-made object to reach the Sun. 
      The Sun keeps surprising us. We are looking forward to seeing what kind of exciting events will be organized by the Sun."

      “The Sun keeps surprising us,” said Kitiashvili. “We are looking forward to seeing what kind of exciting events will be organized by the Sun.”
      These simulations were run on the Pleaides supercomputer at the NASA Advanced Supercomputing facility at NASA Ames over several weeks of runtime, generating terabytes of data.

      An artist’s concept of the early stages of the young star FU Orionis (FU Ori) outburst, surrounded by a disk of material. Credits:
      NASA-JPL, Caltech In 1936, astronomers saw a puzzling event in the constellation Orion: the young star FU Orionis (FU Ori) became a hundred times brighter in a matter of months. At its peak, FU Ori was intrinsically 100 times brighter than our Sun. Unlike an exploding star though, it has declined in luminosity only languidly since then.
      Now, a team of astronomers has wielded NASA’s Hubble Space Telescope‘s ultraviolet capabilities to learn more about the interaction between FU Ori’s stellar surface and the accretion disk that has been dumping gas onto the growing star for nearly 90 years. They find that the inner disk touching the star is extraordinarily hot — which challenges conventional wisdom.
      The observations were made with the telescope’s COS (Cosmic Origins Spectrograph) and STIS (Space Telescope Imaging Spectrograph) instruments. The data includes the first far-ultraviolet and new near-ultraviolet spectra of FU Ori.
      “We were hoping to validate the hottest part of the accretion disk model, to determine its maximum temperature, by measuring closer to the inner edge of the accretion disk than ever before,” said Lynne Hillenbrand of Caltech in Pasadena, California, and a co-author of the paper. “I think there was some hope that we would see something extra, like the interface between the star and its disk, but we were certainly not expecting it. The fact we saw so much extra — it was much brighter in the ultraviolet than we predicted — that was the big surprise.”
      A Better Understanding of Stellar Accretion
      Originally deemed to be a unique case among stars, FU Ori exemplifies a class of young, eruptive stars that undergo dramatic changes in brightness. These objects are a subset of classical T Tauri stars, which are newly forming stars that are building up by accreting material from their disk and the surrounding nebula. In classical T Tauri stars, the disk does not touch the star directly because it is restricted by the outward pressure of the star’s magnetic field.
      The accretion disks around FU Ori objects, however, are susceptible to instabilities due to their enormous mass relative to the central star, interactions with a binary companion, or infalling material. Such instability means the mass accretion rate can change dramatically. The increased pace disrupts the delicate balance between the stellar magnetic field and the inner edge of the disk, leading to material moving closer in and eventually touching the star’s surface.
      This is an artist’s concept of the early stages of the young star FU Orionis (FU Ori) outburst, surrounded by a disk of material. A team of astronomers has used the Hubble Space Telescope’s ultraviolet capabilities to learn more about the interaction between FU Ori’s stellar surface and the accretion disk that has been dumping gas onto the growing star for nearly 90 years. They found that the inner disk, touching the star, is much hotter than expected—16,000 kelvins—nearly three times our Sun’s surface temperature. That sizzling temperature is nearly twice as hot as previously believed. NASA-JPL, Caltech

      The enhanced infall rate and proximity of the accretion disk to the star make FU Ori objects much brighter than a typical T Tauri star. In fact, during an outburst, the star itself is outshined by the disk. Furthermore, the disk material is orbiting rapidly as it approaches the star, much faster than the rotation rate of the stellar surface. This means that there should be a region where the disk impacts the star and the material slows down and heats up significantly. 
      “The Hubble data indicates a much hotter impact region than models have previously predicted,” said Adolfo Carvalho of Caltech and lead author of the study. “In FU Ori, the temperature is 16,000 kelvins [nearly three times our Sun’s surface temperature]. That sizzling temperature is almost twice the amount prior models have calculated. It challenges and encourages us to think of how such a jump in temperature can be explained.”
      To address the significant difference in temperature between past models and the recent Hubble observations, the team offers a revised interpretation of the geometry within FU Ori’s inner region: The accretion disk’s material approaches the star and once it reaches the stellar surface, a hot shock is produced, which emits a lot of ultraviolet light.
      Planet Survival Around FU Ori
      Understanding the mechanisms of FU Ori’s rapid accretion process relates more broadly to ideas of planet formation and survival.
      “Our revised model based on the Hubble data is not strictly bad news for planet evolution, it’s sort of a mixed bag,” explained Carvalho. “If the planet is far out in the disk as it’s forming, outbursts from an FU Ori object should influence what kind of chemicals the planet will ultimately inherit. But if a forming planet is very close to the star, then it’s a slightly different story. Within a couple outbursts, any planets that are forming very close to the star can rapidly move inward and eventually merge with it. You could lose, or at least completely fry, rocky planets forming close to such a star.”
      Additional work with the Hubble UV observations is in progress. The team is carefully analyzing the various spectral emission lines from multiple elements present in the COS spectrum. This should provide further clues on FU Ori’s environment, such as the kinematics of inflowing and outflowing gas within the inner region.
      “A lot of these young stars are spectroscopically very rich at far ultraviolet wavelengths,” reflected Hillenbrand. “A combination of Hubble, its size and wavelength coverage, as well as FU Ori’s fortunate circumstances, let us see further down into the engine of this fascinating star-type than ever before.”
      These findings have been published in The Astrophysical Journal Letters.
      The observations were taken as part of General Observer program 17176.
      The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, also supports mission operations at Goddard.

      Center Commemorates National Disability Employment Awareness Month
      By Serena Whitfield
      In conjunction with National Disability Employment Awareness Month, NASA’s Marshall Space Flight Center held anagencywide virtual event hosted by the Office of Diversity and Equal Opportunity on Oct. 24.
      Marshall team members watched the Webex event in Building 4221.
      From left, Tora Henry, director of the Office of Diversity and Equal Opportunity at Marshall, Chip Dobbs, supply management specialist at Marshall, and Marshall Associate Director Roger Baird pause for a photo following the Oct. 24 virtual event the center hosted as part of National Disability Awareness Month. NASA/Serena Whitfield In alignment with the month’s national theme, “Access to Good Jobs for All,” the program highlighted the perspectives of people with disabilities in the workplace as they navigate the work lifecycle – from applying, to onboarding, career growth and advancement, and day-to-day engagements.
      The event began with Marshall Associate Director Roger Baird welcoming NASA team members.
      “NASA is dedicated to inclusive hiring practices and providing pathways for good jobs and career success for all employees, including workers with disabilities,” Baird said. “Some ways we do this is through targeted recruitment of qualified individuals with disabilities through accessible vacancy announcements, outreach to students with disabilities, and community partnerships.”
      NASA also utilizes Schedule A Authority, a non-competitive Direct Hiring Authority to hire people with disabilities without competition.
      Baird introduced event moderator Joyce Meier, logistics manager at Marshall, who welcomed panelists Casey Denham, Kathy Clark, Paul Spann, and Paul Sullivan, all NASA team members. The panelists from the disability community discussed their work lifecycles, lessons learned in the workplace, and shared a demonstration on colorblindness and its impact.
      Denham discussed some of the best practices for onboarding employees with neurodiversity, a term used to describe people whose brains develop or work differently than the typical brain.
      Marshall team members watch the agencywide virtual event commemorating National Disability Employment Awareness Month. NASA/Serena Whitfield Clark talked about what can be done to continue raising awareness and advocating for disability rights. She said NASA empowers its workforce with knowledge so they can be informed allies to team members with disabilities and foster a safe and inclusive working environment. 
      Spann gave insight into practical steps employers can take to accommodate candidates with deafness, and Sullivan spoke about some key considerations NASA managers should keep in mind to make the job application process more accessible to candidates with low vision.
      Guest speaker Chip Dobbs, supply management specialist at Marshall, talked about his personal experiences with being deaf. Dobbs has worked at NASA for 29 years and said he has never let his disability hold him back, but instead uses it as a gateway to inspire and connect with others.
      The event ended with closing remarks from Tora Henry, director of the Office of Diversity and Equal Opportunity at Marshall. The virtual event placed importance on planning for NASA’s future by promoting equality and addressing the barriers people with disabilities face in the workplace. 
      “As we celebrate National Disability Employment Awareness Month, keep in mind that NASA’s mission of exploring the unknown and pushing the boundaries of human potential requires the contributions of every mind, skill set, and perspective,” Baird said. “Our commitment to inclusivity ensures that no talent goes untapped, and no idea goes unheard because together, we’re not just reaching for the stars, we’re showing the world what’s possible when everyone has a seat at the table.”
      A recording of the event is available here. Learn more about NASA’s agencywide resources for individuals with disabilities as well as the agency’s Disability Employment Program.

      Take 5 with Brooke Rhodes
      By Wayne Smith
      When human exploration of Mars becomes a reality and more than just the stuff of science fiction, Brooke Rhodes will be eager to investigate what astronauts discover on the Red Planet.
      From listening to her talk about her work as an engineer at NASA’s Marshall Space Flight Center, it’s easy to grasp her excitement about the future of human space exploration and NASA’s Moon to Mars architecture.
      Brooke Rhodes is currently on detail as the branch chief of the Avionics and Software Ground Systems Test Branch at NASA’s Marshall Space Flight Center. Working in the Instrument Development, Integration and Test Branch for the past seven years, she’s been responsible for the integration and testing of International Space Station payloads. NASA “I can’t wait for the Mars rovers to have some human company,” said Rhodes, who recently began a detail as the chief of Marshall’s Avionics and Software Ground Systems Test Branch. “I need to know if we can grow Mark Watney (of The Martian movie fame) quantities of potatoes up there. Everything we do to prepare to return humans to the Moon and establish a presence in deep space is building toward putting boots on Mars. It’s an honor and a privilege to be even a small part of it.”
      Rhodes also appreciates the responsibility she takes on in any form in NASA’s exploration missions to benefit humanity. After all, she has worked on hardware for the International Space Station and has had supporting roles for the Mars Ascent Vehicle and Artemis missions.
      “We at Marshall hold an incredible amount of responsibility: responsibility for the welfare of the crew on the space station, responsibility for the welfare of the crew on the Artemis missions, and even the welfare of humanity through the responsibility we have for science on the station and elsewhere,” said Rhodes, who is from Petal, Mississippi, and has worked at Marshall for seven years. “When your missions are as critical as ours, it’s nearly impossible to not be motivated.”
      Now, on to Mars.
      Question: What is your position and what are your primary responsibilities?
      Rhodes: I recently began the detail as the branch chief of the Avionics and Software Ground Systems Test Branch, ES53. Our branch is primarily responsible for the development of hardware-in-the-loop and software development facilities for the Artemis and MAV (Mars Ascent Vehicle) missions. My home organization is ES61, the Instrument Development, Integration and Test Branch, where I’ve been responsible for the integration and testing of International Space Station payloads for the past several years.
      Rhodes with a box of sample cartridge assemblies (SCAs) headed for the International Space Station. Photo courtesy of Brooke Rhodes Question: What has been the proudest moment of your career and why?
      Rhodes: One really cool moment that sticks out was the first time I saw hardware I had been responsible for being used in space. I spent several years as the integration and test lead of the Materials Science Research Rack (MSRR) Sample Cartridge Assemblies (SCAs) and we shipped our first batch of SCAs to the space station in 2018. That shipment was the culmination of years of intense effort and teamwork, so to see them onboard and about to enable materials science was an incredible feeling. There was a moment in particular that felt a bit surreal: prior to our SCA shipment the crew discovered they were missing a couple of fasteners from the onboard furnace, so we had those shipped to us from Europe and I packed them into the SCA flight foam before they shipped to the launch site. The next time I saw those fasteners they were being held up to a camera by one of the crew members, asking if those were the ones they needed for the furnace. Putting fasteners into foam didn’t take much effort, but what it represented was much bigger: being a small part of an international effort to enable science off the Earth, for the Earth, was an incredible moment I’ll carry with me for the rest of my career.
      Question: Who or what inspired you to pursue an education/career that led you to NASA and Marshall?
      Rhodes: I had a couple of lightbulb moments my junior year of high school that eventually set me on my current career path. I very specifically recall sitting in my physics I class and learning how to calculate the planetary motion of Jupiter and thinking I had never learned about anything cooler. Even then, though, NASA didn’t really enter my thoughts. Growing up, working for NASA didn’t even occur to me as something people could actually do – being a “rocket scientist” was just an abstract concept people threw around to indicate something was difficult.
      That changed later when the same teacher who had been teaching us planetary motion took us on a field trip to Kennedy Space Center. The tour guide showing us around the Vehicle Assembly Building was a young employee who said he had majored in aerospace engineering at the University of Tennessee. That was the second lightbulb moment: here was a young person from the Southeast, just like me, who had done something tangible in order to work for NASA. That seemed easy enough, so I decided to major in aerospace engineering at Mississippi State and one day work for NASA. That turned out to not be easy, but definitely doable.
      While at Mississippi State, I was able to complete three NASA internships, one at the Jet Propulsion Laboratory and two at Marshall. Eventually, I was hired on full-time at NASA’s Johnson Space Center, but wound up making my way back to Marshall, where I’ve been ever since. There’s no place on the planet better for enthusiasts of both aerospace engineering and football.

I didn’t actually mean that literally, but then I married Matthew Rhodes and did, indeed, become Mrs. Rhodes.
      Question: What advice do you have for employees early in their NASA career or those in new leadership roles?
      Rhodes: Scary is good. If you aren’t stepping out of your comfort zone you probably aren’t growing, and if you’re experiencing imposter syndrome, you’re probably the right person for the job.
      Question: What do you enjoy doing with your time while away from work?
      Rhodes: While away from work I tend to invest too much of my mental wellbeing into football. To recover from the stresses of work and my football teams being terrible, I like to explore National Parks. The U.S. has some of the most diverse scenery anywhere in the world, and I love getting outside and exploring it.

      Planets Beware: NASA Unburies Danger Zones of Star Cluster
      Most stars form in collections, called clusters or associations, that include very massive stars. These giant stars send out large amounts of high-energy radiation, which can disrupt relatively fragile disks of dust and gas that are in the process of coalescing to form new planets.
      A team of astronomers used NASA’s Chandra X-ray Observatory, in combination with ultraviolet, optical, and infrared data, to show where some of the most treacherous places in a star cluster may be, where planets’ chances to form are diminished.
      In this new composite image, Chandra data (purple) shows the diffuse X-ray emission and young stars in Cygnus OB2, and infrared data from NASA’s now-retired Spitzer Space Telescope (red, green, blue, and cyan) reveals young stars and the cooler dust and gas throughout the region.X-ray: NASA/CXC/SAO/J. Drake et al, IR: NASA/JPL-Caltech/Spitzer; Image Processing: NASA/CXC/SAO/N. Wolk The target of the observations was Cygnus OB2, which is the nearest large cluster of stars to our Sun – at a distance of about 4,600 light-years. The cluster contains hundreds of massive stars as well as thousands of lower-mass stars. The team used long Chandra observations pointing at different regions of Cygnus OB2, and the resulting set of images were then stitched together into one large image.
      The deep Chandra observations mapped out the diffuse X-ray glow in between the stars, and they also provided an inventory of the young stars in the cluster. This inventory was combined with others using optical and infrared data to create the best census of young stars in the cluster.
      In a new composite image, the Chandra data (purple) shows the diffuse X-ray emission and young stars in Cygnus OB2, and infrared data from NASA’s now-retired Spitzer Space Telescope (red, green, blue, and cyan) reveals young stars and the cooler dust and gas throughout the region.
      In these crowded stellar environments, copious amounts of high-energy radiation produced by stars and planets are present. Together, X-rays and intense ultraviolet light can have a devastating impact on planetary disks and systems in the process of forming.
      Planet-forming disks around stars naturally fade away over time. Some of the disk falls onto the star and some is heated up by X-ray and ultraviolet radiation from the star and evaporates in a wind. The latter process, known as “photoevaporation,” usually takes between five and 10 million years with average-sized stars before the disk disappears. If massive stars, which produce the most X-ray and ultraviolet radiation, are nearby, this process can be accelerated.
      The researchers using this data found clear evidence that planet-forming disks around stars indeed disappear much faster when they are close to massive stars producing a lot of high-energy radiation. The disks also disappear more quickly in regions where the stars are more closely packed together.
      For regions of Cygnus OB2 with less high-energy radiation and lower numbers of stars, the fraction of young stars with disks is about 40%. For regions with more high-energy radiation and higher numbers of stars, the fraction is about 18%. The strongest effect – meaning the worst place to be for a would-be planetary system – is within about 1.6 light-years of the most massive stars in the cluster.
      A separate study by the same team examined the properties of the diffuse X-ray emission in the cluster. They found that the higher-energy diffuse emission comes from areas where winds of gas blowing away from massive stars have collided with each other. This causes the gas to become hotter and produce X-rays. The less energetic emission probably comes from gas in the cluster colliding with gas surrounding the cluster.
      Two separate papers describing the Chandra data of Cygnus OB2 are available. The paper about the planetary danger zones, led by Mario Giuseppe Guarcello (National Institute for Astrophysics in Palermo, Italy), appeared in the November 2023 issue of the Astrophysical Journal Supplement Series, and is available here. The paper about the diffuse emission, led by Juan Facundo Albacete-Colombo (University of Rio Negro in Argentina) was published in the same issue of Astrophysical Journal Supplement, and is available here.

      NASA Begins New Deployable Solar Array Tech Demo on Pathfinder Spacecraft
      NASA recently evaluated initial flight data and imagery from Pathfinder Technology Demonstrator-4 (PTD-4), confirming proper checkout of the spacecraft’s systems including its on-board electronics as well as the payload’s support systems such as the small onboard camera. Shown is a test image of Earth taken by the payload camera, shortly after PTD-4 reached orbit. This camera will continue photographing the technology demonstration during the mission. 
      A test image of Earth taken by NASA’s Pathfinder Technology Demonstrator-4’s onboard camera. The camera will capture images of the Lightweight Integrated Solar Array and anTenna upon deployment.NASA Payload operations are now underway for the primary objective of the PTD-4 mission – the demonstration of a new power and communications technology for future spacecraft. The payload, a deployable solar array with an integrated antenna called the Lightweight Integrated Solar Array and anTenna, or LISA-T, has initiated deployment of its central boom structure. The boom supports four solar power and communication arrays, also called petals. Releasing the central boom pushes the still-stowed petals nearly three feet away from the spacecraft bus. The mission team currently is working through an initial challenge to get LISA-T’s central boom to fully extend before unfolding the petals and beginning its power generation and communication operations.
      Small spacecraft on deep space missions require more electrical power than what is currently offered by existing technology. The four-petal solar array of LISA-T is a thin-film solar array that offers lower mass, lower stowed volume, and three times more power per mass and volume allocation than current solar arrays. The in-orbit technology demonstration includes deployment, operation, and environmental survivability of the thin-film solar array.  
      “The LISA-T experiment is an opportunity for NASA and the small spacecraft community to advance the packaging, deployment, and operation of thin-film, fully flexible solar and antenna arrays in space. The thin-film arrays will vastly improve power generation and communication capabilities throughout many different mission applications,” said John Carr, deputy center chief technologist at NASA’s Marshall Space Flight Center. “These capabilities are critical for achieving higher value science alongside the exploration of deep space with small spacecraft.”
      NASA teams are testing a key technology demonstration known as LISA-T, short for the Lightweight Integrated Solar Array and anTenna. It’s a super compact, stowable, thin-film solar array that when fully deployed in space, offers both a power generation and communication capability for small spacecraft. LISA-T’s orbital flight test is part of the Pathfinder Technology Demonstrator series of missions. (NASA) The Pathfinder Technology Demonstration series of missions leverages a commercial platform which serves to test innovative technologies to increase the capability of small spacecraft. Deploying LISA-T’s thin solar array in the harsh environment of space presents inherent challenges such as deploying large highly flexible non-metallic structures with high area to mass ratios. Performing experiments such as LISA-T on a smaller, lower-cost spacecraft allows NASA the opportunity to take manageable risk with high probability of great return. The LISA-T experiment aims to enable future deep space missions with the ability to acquire and communicate data through improved power generation and communication capabilities on the same integrated array.
      The PTD-4 small spacecraft is hosting the in-orbit technology demonstration called LISA-T. The PTD-4 spacecraft deployed into low Earth orbit from SpaceX’s Transporter-11 rocket, which launched from Space Launch Complex 4E at Vandenberg Space Force Base in California on Aug. 16. Marshall designed and built the LISA-T technology as well as LISA-T’s supporting avionics system. NASA’s Small Spacecraft Technology program, based at NASA’s Ames Research Center and led by the agency’s Space Technology Mission Directorate, funds and manages the PTD-4 mission as well as the overall Pathfinder Technology Demonstration mission series. Terran Orbital Corporation of Irvine, California, developed and built the PTD-4 spacecraft bus, named Triumph.

      NASA SPoRT’s Streamflow-AI Helps with Flood Preparedness in Texas
      By Paola Pinto
      For more than two decades, the NASA Short-term Prediction Research and Transition Center (SPoRT) within the NASA Earth Science Office at Marshall Space Flight Center has been at the forefront of developing and maintaining decision-making tools for meteorological predictions.
      This image represents the first instance of predictions getting into moderate flooding in Pine Island Bayou. At 14 feet (start of the moderate flooding category), Cooks Lake Road becomes unsafe for most vehicles. NASA Jonathan Brazzell, a service hydrologist at the National Weather Service (NWS) office in Lake Charles, Louisiana, highlighted a recent example of SPoRT’s impact while he was doing forecasting for Texas streams.
      Brazzell, who manages the South Texas and South Louisiana regions, emphasized the practical applications and significant impacts of the Machine Learning model developed by NASA SPoRT to predict future stream heights, known as the SPoRT Streamflow A.I. During a heavy rainfall event this past spring, he noted the challenge of forecasting flooding beyond 48 hours. SPoRT has worked closely with the NWS offices to develop a machine learning tool capable of predicting river flooding beyond two days and powered by the SPoRT Land Information System.
      “Previously, we relied on actual gauge information and risk assessments based on predicted precipitation,” Brazzell said. “Now, with this machine learning, we have a modeling tool that provides a much-needed predictive capability.”
      During forecasted periods of heavy precipitation from early to mid-May, Brazzell monitored potential flooding events and their magnitude using NASA SPoRT’s Streamflow-AI, which provided essential support to the Pine Island Bayou and Big Cow Creek communities in south Texas.
      Streamflow A.I. enabled local authorities to provide advance notice, allowing residents to prepare adequately for the event. Due to the benefit of three to seven-day flood stage predictions, the accurate forecasts helped county officials decide on road closures and evacuation advisories; community officials advised residents to gather a seven-day supply of necessities and relocate their vehicles, minimizing disruption and potential damage.
      Brazzell highlighted specific instances where the machine learning outputs were critical. For example, during the event that peaked around May 6, Streamflow A.I. accurately predicted the rise in stream height, allowing for timely road closures and advisories. These predictions were shared with county officials and were pivotal in their decision-making process.
      This image shows the water levels after rainfall and predicts a moderate stream height in Pine Island Bayou. NASA Brazzell shared that integrating SPoRT’s machine learning capabilities with their existing tools, such as flood risk mapping, proved invaluable. Although the machine learning outputs had been operational for almost two years after Hurricane Harvey, this season has provided their first significant applications in real-time scenarios due to persistent conditions of below-normal precipitation and ongoing drought.
      He also mentioned the broader applications of Streamflow A.I., including its potential use in other sites beyond those currently being monitored. He expressed interest in expanding the use of machine learning stream height outputs to additional locations, citing the successful application in current sites as a compelling reason for broader implementation.
      NASA SPoRT users’ experiences emphasize how crucial advanced prediction technologies are in hydrometeorology and emergency management operations. Based on Brazzell’s example, it is reasonable to say that the product’s ability to provide accurate, timely data greatly improves decision-making processes and ensures public safety. The partnership between NASA SPoRT and operational agencies like NOAA/NWS and county response teams demonstrates how research and operations can be seamlessly integrated into everyday practices, making a tangible difference in communities vulnerable to high-impact events.
      As the Streamflow A.I. product continues to evolve and expand its applications, it holds significant promise for improving disaster preparedness and response efforts across various regions that experience different types of flooding events.
      The Streamflow-AI product provides a 7-day river height or stage forecasts at select gauges across the south/eastern U.S. You can find the SPoRT training item on Streamflow-AI here.
