NASA/Kim Shiflett and Isaac Watson In celebration of Women’s History Month, NASA highlights the multifaceted group of women behind the launch and recovery efforts for Artemis missions. They are a driving force in preparing and planning for crewed missions and are helping inspire the next generation of space explorers – the Artemis Generation. On the left is Artemis Launch Director Charlie Blackwell-Thompson and some of the women of the launch team wearing green to symbolize they are “go” for launch. As the agency prepares to return to the Moon under Artemis, the teams in the launch control center at NASA’s Kennedy Space Center in Florida are responsible for launching the SLS (Space Launch System) rocket and Orion spacecraft. The team consists of about 30% women, in contrast to when there was only one woman sitting on launch console during the Apollo 11 Moon landing mission. On the right is Artemis Landing and Recovery Director Lili Villarreal during Underway Recovery Test-11. This most recent recovery test marked the first time teams and the Artemis II astronauts practiced the procedures and operations they will undergo after Orion splashes down in the Pacific Ocean at the end of the Artemis II test flight.

The road to the Moon landing cleared a major hurdle in March 1969 with the flight of Apollo 9 that tested all components of the spacecraft in low Earth orbit. Astronauts James A. McDivitt and Russell L. Schweickart flew the Lunar Module (LM) Spider while David R. Scott awaited their return in the Command Module (CM) Gumdrop. The success of Apollo 9 paved the way for Apollo 10, the next mission planned for May, to test the combined spacecraft in lunar orbit. Preparations for Apollo 10 continued with the rollout of the Saturn V to its launch pad. And if that dress rehearsal mission completed all its objectives, Apollo 11 could achieve the first Moon landing in July. The astronauts for that mission continued their training as engineers tested the spacecraft and assembled the rocket. Apollo 9 Left: Apollo 9 astronauts James A. McDivitt, left, David R. Scott, and Russell L. Schweickart pose in front of their Saturn V rocket at NASA’s Kennedy Space Center in Florida. Middle: The Apollo 9 crew patch. Right: Liftoff of Apollo 9! At 11 a.m. on March 3, 1969, Apollo 9 lifted off from Launch Pad 39A at NASA’s Kennedy Space Center (KSC) in Florida. For only the second time, the giant Saturn V lifted three astronauts into space. Although planned for Feb. 28, managers delayed the liftoff by three days to give the astronauts time to recover from upper respiratory infections. The incident prompted NASA to institute a preflight medical quarantine for astronauts on future missions to minimize their risk of contracting infectious diseases.

Controllers in Firing Room 2 of the Launch Control Center (LCC) monitored Apollo 9’s smooth countdown. Vice President Spiro T. Agnew, who chaired the National Aeronautics and Space Council, attended the launch, escorted by NASA Acting Administrator Thomas O. Paine and KSC Director Kurt H. Debus. As soon as the Saturn V cleared the launch tower, control of the flight switched from the LCC to Mission Control at the Manned Spacecraft Center (MSC), now NASA’s Johnson Space Center in Houston. Apollo 9 Lead Flight Director Eugene F. Kranz and his team of controllers monitored the launch. Eleven minutes after liftoff, the Saturn V’s three stages placed Apollo 9 in orbit around the Earth. During the 10-day mission, Flight Directors Gerald D. Griffin and M.P. “Pete” Frank took their turns along with Kranz leading their teams to monitor the flight.

Schweickart on Spider’s front porch during the mission’s dual spacewalk – note fellow astronaut David R. Scott reflected in Schweickart’s visor. Right: Scott in the open hatch of the Command Module Gumdrop. Two hours and 41 minutes after launch, the Command and Service Module (CSM) separated from the S-IVB third stage and pulled a safe distance away to begin the Transposition and Docking maneuver. Scott turned Gumdrop around to face Spider, still attached to the S-IVB, and slowly closed the gap between the two spacecraft, completing the first successful docking of the Apollo program. About an hour later, springs ejected the docked spacecraft from the S-IVB. Over the next few hours, ground controllers twice restarted the S-IVB’s engine to simulate a Trans Lunar Injection, eventually sending the spent rocket stage into solar orbit. Meanwhile, the astronauts pressurized the tunnel between Gumdrop and Spider and connected umbilicals to power the LM while the two spacecraft remained docked. The astronauts next performed the first of eight planned burns of the Service Module’s (SM) Service Propulsion System (SPS) engine, a five-second maneuver that raised the spacecraft’s orbit. The burn validated that the docking mechanism between the two vehicles and that the LM itself could withstand the firing of the large SPS engine. The crew settled down for their first night’s sleep in space – for the first time in the Apollo Program, all crew members slept at the same time and not in shifts as on previous missions. The next day, the crew conducted three SPS engine burns of varying durations to demonstrate the controllability of the docked vehicles using the spacecraft’s digital autopilot. The third day saw the initial activation of the LM Spider. Schweickart first and then McDivitt floated through the tunnel from Gumdrop. They closed the hatch, brought the LM’s systems to life, and extended the vehicle’s four landing legs. McDivitt informed Mission Control that Schweickart had experienced symptoms of space motion sickness, including vomiting twice, but that he now felt better. Mission Control, in consultation with flight surgeons and the crew, agreed that the mission could continue as planned, but out of an abundance of caution they curtailed the spacewalk scheduled for the next day. Instead of translating to Gumdrop and back as originally planned, Schweickart would remain on Spider’s front porch to evaluate the spacesuit and the Portable Life Support System (PLSS) backpack. Schweickart and McDivitt then began the first TV transmission of the mission, a seven-minute broadcast showing the duo in the confined space of the LM. McDivitt and Schweickart moved on to perform the first test of the Descent Propulsion System (DPS) engine, the rocket used to land the LM on the Moon. Although successfully tested during the uncrewed Apollo 5 mission in January 1968, this test included a CSM docked to the LM. The burn evaluated if the LM’s engine could serve as a backup in case of a problem with the SPS – in retrospect a very useful test given Apollo 13 relied on the method just over a year later. After the 372-second burn, capsule communicator (capcom) Stuart A. Roosa called up to the crew, “Spider, that was a beautiful burn, man, you were right down the tube,” generating this response from McDivitt, “Looked pretty neat from here, too.” McDivitt and Schweickart deactivated Spider for the night and transferred back to Gumdrop. The crew conducted the 43-second fifth burn of the SPS to circularize the spacecraft’s orbit. The Apollo 9 astronauts began their fourth day in space by donning their spacesuits and Schweicakrt and McDivitt once again transferred to Spider. In the LM, Schweickart, fully recovered from his earlier illness, donned the PLSS that provided him with oxygen during his spacewalk. Scott received his life support via umbilicals connected to the CM and McDivitt similarly used the LM’s life support system. McDivitt depressurized Spider, and minutes later Scott did the same with Gumdrop. Schweickart floated out through the LM’s side hatch onto the front porch, exclaiming “Hey, this is like spectacular.” He placed his feet into specialized gold-painted foot restraints dubbed the “golden slippers.” Scott then opened the CM side hatch and floated partway out of the spacecraft. Mission Control now communicated with three different parties, with Schweickart picking up the callsign Red Rover, a nod to his red hair. Scott retrieved thermal samples from the outside of Gumdrop. Schweickart did the same from the outside of Spider and tested out the handrails near the hatch and found them to be easy for maneuvering. Scott and Schweickart reentered their respective vehicles, having each spent about 37 minutes outside. Mission Control considered this first, and the only one before the Moon landing, test of the spacesuits and PLSS a complete success. After a 15-minute TV broadcast, McDivitt and Schweickart returned to Gumdrop to rejoin Scott for the night. Left: The Lunar Module (LM) Spider with James A. McDivitt and Russell L. Schweickart aboard, begins its departure from the Command Module (CM) Gumdrop, with David R. Scott aboard. Middle: McDivitt and Schweickart aboard Spider’s ascent stage have returned to Gumdrop. Right: View of Gumdrop from Spider. For their fifth day in space, the Apollo 9 crew had a full plate – undocking of Spider from Gumdrop, testing the LM’s Descent and Ascent Stage engines by conducting separation maneuvers followed by a rendezvous and docking with the CM. This marked the first time astronauts flew in a spacecraft not designed to reenter the Earth’s atmosphere, making redocking with Gumdrop essential. Spider backed away from Gumdrop to about 50 feet and began a slow turn so Scott in the CM could inspect it. He commented about Spider, “That’s a nice looking machine.” A small 10-second burn by the SM’s Reaction Control System (RCS) thrusters increased the separation distance to about three miles. About 45 minutes after undocking, McDivitt fired Spider’s DPS engine for 19 seconds, first at 10% thrust then throttling it up to 40% thrust, to begin the separation maneuver that placed it about 50 miles from Gumdrop before orbital mechanics brought the two spacecraft closer again. The next maneuver in the separation sequence, a 22-second DPS burn, opened the distance to about 100 miles. To begin the rendezvous back to Gumdrop, McDivitt first fired Spider’s Ascent Stage RCS thrusters for 32 seconds, at the same time jettisoning the Descent Stage. It remained in orbit until March 22, burning up on reentry over the Indian Ocean. The next rendezvous maneuver, lasting three seconds, tested the Ascent Propulsion System (APS) engine for the first time, followed by a second APS burn lasting 38 seconds, putting Spider on an intercept course with Gumdrop. Two small course corrections refined the trajectory and Spider stopped about 100 feet from Gumdrop to begin a pitchover maneuver, allowing Scott to inspect the ascent stage including its engine, commenting, “You’re the biggest, friendliest, funniest looking Spider I’ve ever seen.” The two craft docked, having flown separately for six hours 23 minutes. Two hours after docking, McDivitt and Schweickart rejoined Scott in Gumdrop, and then they jettisoned Spider. Mission Control commanded Spider’s APS to fire for six minutes, placing it into a highly elliptical Earth orbit from which it did not decay until Oct. 23, 1981. The Apollo 9 astronauts had met their mission’s primary objectives, and they still had five more days in space. Left: Experiment S065 multispectral camera installed on the Command Module’s side hatch window. Middle: Multispectral image of the San Diego area. Right: Color infrared image of the Salton Sea area in California. The first major task of flight day six involved the sixth SPS engine. This brief one and a half second burn lowered the low point of Gumdrop’s orbit, to enhance a backup capability to use the RCS thrusters for the deorbit burn at the end of the mission, should a problem arise with the SPS. Shortly after this burn, the crew set up the one formal scientific investigation of their mission – Experiment S065 Multispectral Terrain Photography, a cluster of four Hasselblad 70 mm cameras mounted in Gumdrop’s round hatch window. The experiment provided photographs taken simultaneously in four specific portions of the visible and near infrared spectrum. The experiment served as a precursor for the Earth Resources Technology Satellite (ERTS), later renamed Landsat, and for multispectral photography conducted aboard the Skylab space station in the early 1970s. Over the next four days, the astronauts continued observations with the S065 camera system, exposing 127 complete four-frame sets.

McDivitt safely aboard the Guadalcanal. On flight day eight, the crew completed the seventh SPS burn, a 25-second firing to establish the proper trajectory for the deorbit burn. On Mar. 13, 1969, after 151 revolutions around the Earth and while passing over Hawaii, the crew fired the SPS engine for the eighth and final time. Lasting just under 12 seconds, the burn brought Apollo 9 out of orbit. Gumdrop separated from its SM and pointed its heat shield in the direction of flight. During reentry, a sheath of ionized gas formed around the capsule by the rapid deceleration led to a 4-minute radio blackout, after which the drogue parachutes deployed. The three main parachutes opened at 10,000 feet altitude, slowing the spacecraft to about 22 miles per hour at splashdown.

The splashdown occurred in the Atlantic Ocean about 670 miles south-southwest of Bermuda, and about 3 miles from the prime recovery ship the U.S.S. Guadalcanal (LPH-7). McDivitt, Scott, and Schweickart had spent 241 hours and 54 seconds in space. Forty-nine minutes after splashdown, recovery teams had the crew aboard the recovery ship. The next day, a helicopter flew them to Eleuthera in the Bahamas, where they boarded a plane to KSC for a brief ceremony, and then back to Houston for a large welcome home reception and a reunion with their families at Ellington Air Force Base. The successful Apollo 9 mission, the most complex crewed space mission flown to that time, brought the Moon landing one step closer. Left: In Washington, D.C., Vice President Spiro T.

They in turn presented the Vice President with a framed American flag they had taken to space. Among other postflight events and celebrations, the trio attended the Paris Air Show and on May 29 met Soviet cosmonauts Vladimir A. Shatalov and Aleksei S. Yeliseyev who had flown as part of the Soyuz 4 and 5 docking and spacewalk crew exchange mission in January 1969.

Workers offloaded Gumdrop from the Guadalcanal in Norfolk, Virginia, for transport aboard a U.S. Air Force cargo jet to Long Beach, California, from where they trucked it to the North American Rockwell plant in Downey for postflight inspection. NASA transferred Gumdrop to the Smithsonian Institution in 1973. In 1977, it went on display at the Michigan Space and Science Center in Jackson, Michigan, McDivitt’s hometown. When that facility closed in 2004, Gumdrop transferred to the San Diego Air & Space Museum, where visitors can view it today.

Right: Apollo 10 astronauts John W. Young, left, Eugene A. Cernan, and Thomas P. Stafford pose before their Saturn V rocket. On March 11, as the Apollo 9 astronauts neared the end of their mission, workers at KSC rolled the Apollo 10 Saturn V vehicle from the Vehicle Assembly Building (VAB) to its launch pad. Apollo 10’s assembly marked the first use of the VAB’s High Bay 2, requiring the stack to exit the VAB’s rear and make a sweeping loop around the building to reach the crawlerway to the launch pads. Apollo 10 also marked the first use of Pad 39B. On March 17, NASA managers formally set Apollo 10’s launch date as May 18. Apollo 10 astronauts Thomas P. Stafford, John W. Young, and Eugene A. Cernan and their backups L. Gordon Cooper, Donn F. Eisele, and Edgar D. Mitchell continued training in spacecraft simulators and testing their spacesuits in vacuum chambers. On March 27, the prime crew conducted a walk-through of Pad 39B and trained on emergency escape procedures. The next day, the backup crew practiced water egress training in the Water Immersion Facility in MSC’s Building 260, and repeated the training in the Gulf of Mexico the following week. Apollo 11 Left: Apollo 11 astronauts Neil A. Armstrong, left, Edwin E. “Buzz” Aldrin, and Michael Collins, not visible, prepare for an altitude chamber test of their Command Module at NASA’s Kennedy Space Center (KSC) in Florida. Middle: Apollo 11 backup crew members James A. Lovell and Frew W. Haise have entered the chamber for a Lunar Module altitude test.

The spacecraft for Apollo 11 continued testing in KSC’s Manned Spacecraft Operations Building (MSOB). With their historic mission only five months away, the Apollo 11 prime crew of Neil A. Armstrong, Michael Collins, and Edwin E. “Buzz” Aldrin and their backups James A. Lovell, William A. Anders, and Fred W. Haise busied themselves training for the Moon landing, spending time in spacecraft simulators. The prime and backup crews participated in altitude chamber tests of both their CM and LM. Mobile Quarantine Facility, Lunar Receiving Laboratory, and Lunar Module Drop Tests Left: Flight surgeon Dr. William R. Carpentier, left, and the three astronaut surrogates wearing Biological Isolation Garments, prepare to enter the Mobile Quarantine Facility (MQF) aboard the U.S.S. Guadalcanal. Middle: Dr. Carpentier, left, astronaut surrogates Paul H. Kruppenbacher, Arthur E. Lizza, and Michael T. “Tex” Ward, and engineer John K. Hirasake inside the MQF aboard the Guadalcanal. Right: Workers at Norfolk Naval Air Station in Virginia lift the MQF off the Guadalcanal onto a truck for its return to Houston. Preparations for ground support facilities for the first lunar landing mission continued. In conjunction with the Apollo 9 splashdown and recovery operations aboard the Guadalcanal, NASA conducted a simulation of recovery operations of astronauts returning from a lunar mission. NASA Flight Surgeon Dr. William R. Carpentier, project engineer John K. Hirasaki, and three astronaut stand-ins, Paul H. Kruppenbacher, Michael T. “Tex” Ward, and Arthur E. Lizza, spent 10 days inside a Mobile Quarantine Facility (MQF), a modified Airstream trailer designed to temporarily house astronauts returning from the Moon. The three astronaut surrogates began the simulation by entering a mockup CM that sailors placed in the ocean and recovered as if returning from a space mission. The trio donned Biological Isolation Garments (BIG), meant to prevent contamination of Earth by any possible lunar organisms. Once on board the Guadalcanal, the three accompanied by Carpentier and Hirasaki entered the MQF for four days, where the just-recovered Apollo 9 crew visited them through the window of the trailer. The five stayed inside the MQF except for the short time it was transferred from the Guadalcanal to a waiting transport aircraft at Norfolk Naval Air Station and flown back to Houston. After offloading, the MQF and its five inhabitants transferred to the Lunar Receiving Laboratory (LRL) in MSC’s Building 37 to begin a simulated quarantine. Overall, the exercise tested the procedures for the activities after the first lunar landing mission, with many lessons learned. Left: During a simulation, workers line up in the kitchen of the Crew Reception Area of the Lunar Receiving Laboratory at the Manned Spacecraft Center (MSC), now NASA’s Johnson Space Center in Houston. Middle: The Vibration and Acoustics Test Facility (VATF) at MSC. Right: The Lunar Module during drop testing in the VATF. Managers, scientists, technicians, and engineers conducted a 30-day simulation in the LRL, the most complex test of the facility to verify that all its components would be ready to support crewmembers and their samples returning from the Moon, possibly by July 1969. A separate seven-day simulation of the astronaut quarantine capabilities in the LRL’s Crew Reception Area began on March 25. Fifteen NASA and contractor employees, most of whom would participate in the activities following the actual lunar landing mission, demonstrated the logistics of maintaining astronauts and support staff in isolation. All biological barriers operated during the simulation, and the only contact test personnel had with the outside world was via telephone or through glass walls. The first part of the test included the simulated arrival of lunar materials and film, followed the next day by the arrival of the stand-in crew. The last part of the test included the process for releasing the crew and personnel from quarantine. The Structures and Mechanics Division at MSC conducted a series of drop tests in the Vibration and Acoustic Test Facility (VATF) to verify that the LM’s systems would operate following a lunar landing. The LM’s manufacturer, the Grumman Aircraft Engineering Corporation, located in Bethpage, New York, provided technical support for the tests using LM-2, a flight qualified vehicle with all subsystems installed. To simulate the LM’s configuration at landing, workers filled the tanks in the ascent stage with inert fluid to mimic a full load of fuel, while keeping the descent stage tanks mostly empty as they would be following the powered descent from orbit. The series of five tests began on March 21, 1969, and finished on May 7. Engineers dropped LM-2 from heights ranging from eight to 24 inches onto artificial slopes and obstructions to simulate landings on rough lunar terrain. Successful completion of the drop tests removed a constraint from carrying out the first lunar landing. Visitors can view LM-2 on display at the Smithsonian Institution’s National Air and Space Museum in Washington, D.C.

Right: In KSC’s Manned Spacecraft Operations Building, workers uncrate the Apollo 12 Command and Service Modules, foreground, as they continue work on the Apollo 11 spacecraft. In case Apollo 11 could not achieve the Moon landing in July, NASA planned to try again with Apollo 12 in September. To protect for that launch date, components of the rocket and spacecraft began arriving at KSC. The Saturn V’s S-IVB third stage arrived on March 10 and workers placed it in storage in the VAB until the other two stages arrived in April and May. The Apollo 12 LM’s two stages arrived on March 24, and workers transported them to the MSOB. The CM and SM arrived four days later, and they shared space in the MSOB with the Apollo 11 spacecraft undergoing testing.

Astronauts will test drive NASA’s Orion spacecraft for the first time during the agency’s Artemis II test flight next year. While many of the spacecraft’s maneuvers like big propulsive burns are automated, a key test called the proximity operations demonstration will evaluate the manual handling qualities of Orion. During the approximately 70-minute demonstration set to begin about three hours into the mission, the crew will command Orion through a series of moves using the detached upper stage of the SLS (Space Launch System) rocket as a mark. The in-space propulsion stage, called the ICPS (interim cryogenic propulsion stage), includes an approximately two-foot target that will be used to evaluate how Orion flies with astronauts at the controls. “There are always differences between a ground simulation and what an actual spacecraft will fly like in space,” said Brian Anderson, Orion rendezvous, proximity operations, and docking manager within the Orion Program at NASA’s Johnson Space Center in Houston. “The demonstration is a flight test objective that helps us reduce risk for future missions that involve rendezvous and docking with other spacecraft.” After NASA’s Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen are safely in space, the Moon rocket’s upper stage will fire twice to put Orion on a high Earth orbit trajectory. Then, the spacecraft will automatically separate from the rocket stage, firing several separation bolts before springs push Orion a safe distance away. As the spacecraft and its crew move away, Orion will perform an automated backflip to turn around and face the stage. At approximately 300 feet away, Orion will stop its relative motion. The crew will take control and use the translational and rotational hand controllers and display system to make very small movements to ensure Orion is responding as expected. Next, the crew will very slowly pilot Orion to within approximately 30 feet of the stage. A two-foot auxiliary target mounted inside the top of the stage, similar to the docking target used by spacecraft visiting the International Space Station, will guide their aim. “The crew will view the target by using a docking camera mounted inside the docking hatch window on the top of the crew module to see how well aligned they are with the docking target mounted to the ICPS,” Anderson said. “It’s a good stand in for what crews will see when they dock with Starship on Artemis III and to the Gateway on future missions.” About 30 feet from the stage, Orion will stop and the crew will checkout the spacecraft’s fine handling qualities to evaluate how it performs in close proximity to another spacecraft. Small maneuvers performed very close to the ICPS will be done using the reaction control system thrusters on Orion’s European Service Module. Orion will then back away and allow the stage to turn to protect its thermal properties. The crew will follow the stage, initiate a second round of manual maneuvers using another target mounted on the side of the stage, approach within approximately 30 feet, perform another fine handling quality check out, then back away. At the end of the demonstration, Orion will perform an automated departure burn to move away from the ICPS before the stage then fires to re-enter Earth’s atmosphere over a remote location in the Pacific Ocean. During Orion’s departure burn, engineers will use the spacecraft’s docking camera to gather precise positioning measurements, which will help inform navigation during rendezvous activities on future missions in the lunar environment, where there is no GPS system. Because the Artemis II Orion is not docking with another spacecraft, it is not equipped with a docking module containing lights and therefore is reliant on the ICPS to be lit enough by the Sun to allow the crew to see the targets. “As with many of our tests, it’s possible the proximity operations demonstration won’t go exactly as expected,” said Anderson. “Even if we don’t accomplish every part of the demonstration, we’ll continue on with the test flight as planned to accomplish our primary objectives, including evaluating Orion’s systems with crew aboard in the deep space environment and keeping the crew safe during the mission.” The approximately 10-day Artemis II flight will test NASA’s foundational human deep space exploration capabilities, the SLS rocket and Orion spacecraft, for the first time with astronauts and will pave the way for lunar surface missions, including landing the first woman, first person of color, and first international partner astronaut on the Moon.

A NASA-funded commercial space station, Blue Origin’s Orbital Reef, recently completed testing milestones for its critical life support system as part of the agency’s efforts for new destinations in low Earth orbit. The four milestones are part of a NASA Space Act Agreement originally awarded to Blue Origin in 2021 and focused on the materials and designs for systems to clean, reclaim, and store the air and water critical for human spaceflight. NASA is working closely with commercial companies to develop new space stations capable of providing services to NASA and others, which will ensure that the U.S. maintains a continuous human presence in low Earth orbit and provides direct benefits for people on Earth. “These milestones are critical to ensuring that a commercial destination can support human life so NASA astronauts can continue to have access to low Earth orbit to conduct important scientific research in the unique microgravity environment,” said Angela Hart, manager of NASA’s Commercial Low Earth Orbit Development Program. “Additionally, each milestone that is completed allows NASA to gain insight into our partner’s progress on station design and development.” Humans living and working in space do so in a closed environment that must be monitored and controlled. On the International Space Station, components for the environmental control and life support system maintain clean air and water for astronauts. The regenerative system recycles and reclaims most of the water and oxygen produced by normal human activities. This significantly reduces the amount of mass that would have to be launched to the orbiting laboratory for these functions. Orbital Reef will have a similar system in place. All four milestones tested different parts of the system, including a trace contaminant control test, water contaminant oxidation test, urine water recovery test, and water tank test. The trace contaminant control test screened materials to remove harmful impurities from the air. The water containment oxidation test, urine water recovery test, and water tank test all focused on potential cleaning, reclaiming, and storing technologies. NASA is supporting the design and development of multiple commercial space stations, including Blue Origin’s Orbital Reef, through funded and unfunded agreements. The current design and development phase will be followed by the procurement of services from one or more companies, where NASA aims to be one of many customers for low Earth orbit destinations. NASA’s commercial strategy for low Earth orbit will provide the government with reliable and safe services at a lower cost and enable the agency to focus on Artemis missions to the Moon in preparation for Mars, while also continuing to use low Earth orbit as a training and proving ground for those deep space missions.

4 min read NASA Radar Finds Ice Deposits at Moon’s North Pole Additional evidence of water activity on moon Using data from a NASA radar that flew aboard India’s Chandrayaan-1 spacecraft, scientists have detected ice deposits near the moon’s north pole. NASA’s Mini-SAR instrument, a lightweight, synthetic aperture radar, found more than 40 small craters with water ice. The craters range in size from 1 to 9 miles (2 to15 km) in diameter. Although the total amount of ice depends on its thickness in each crater, it’s estimated there could be at least 1.3 trillion pounds (600 million metric tons) of water ice. Mini-SAR map of the Circular Polarization Ratio (CPR) of the north pole of the Moon. Fresh, “normal” craters (red circles) show high values of CPR inside and outside their rims. This is consistent with the distribution of rocks and ejected blocks around fresh impact features, indicating that the high CPR here is surface scattering. The “anomalous” craters (green circles) have high CPR within, but not outside their rims. Their interiors are also in permanent sun shadow. These relations are consistent with the high CPR in this case being caused by water ice, which is only stable in the polar dark cold traps. We estimate over 600 million cubic meters (1 cubic meter = 1 metric ton) of water in these features. The Mini-SAR has imaged many of the permanently shadowed regions that exist at both poles of the Moons. These dark areas are extremely cold and it has been hypothesized that volatile material, including water ice, could be present in quantity here. The main science object of the Mini-SAR experiment is to map and characterize any deposits that exist. Mini-SAR is a lightweight (less than 10 kg) imaging radar. It uses the polarization properties of reflected radio waves to characterize surface properties. Mini-SAR sends pulses of radar that are left-circular polarized. Typical planetary surfaces reverse the polarization during the reflection of radio waves, so that normal echoes from Mini-SAR are right circular polarized. The ratio of received power in the same sense transmitted (left circular) to the opposite sense (right circular) is called the circular polarization ratio (CPR). Most of the Moon has low CPR, meaning that the reversal of polarization is the norm, but some targets have high CPR. These include very rough, fresh surfaces (such as a young, fresh crater) and ice, which is transparent to radio energy and multiply scatters the pulses, leading to an enhancement in same sense reflections and hence, high CPR. CPR is not uniquely diagnostic of either roughness or ice; the science team must take into account the environment of the occurrences of high CPR signal to interpret its cause. The fresh impact crater Main L (14 km diameter, 81.4° N, 22° E ), which shows high CPR inside and outside its rim. SC is the “same sense, circular” polarization; CPR is “circular polarization ratio.” The histograms at right show that the high CPR values within (red line) and outside the crater rim (green line) are nearly identical. Numerous craters near the poles of the Moon have interiors that are in permanent sun shadow. These areas are very cold and water ice is stable there essentially indefinitely. Fresh craters show high degrees of surface roughness (high CPR) both inside and outside the crater rim, caused by sharp rocks and block fields that are distributed over the entire crater area. However, Mini-SAR has found craters near the north pole that have high CPR inside, but not outside their rims. This relation suggests that the high CPR is not caused by roughness, but by some material that is restricted within the interiors of these craters. We interpret this relation as consistent with water ice present in these craters. The ice must be relatively pure and at least a couple of meters thick to give this signature. An “anomalous” crater on the floor of Rozhdestvensky (9 km Diameter, 84.3° N, 157° W), near the north pole of the Moon. This feature shows high CPR within the crater rim, but low CPR outside, suggesting that roughness (which occurs throughout a fresh crater) is not the cause of the elevated CPR. This feature’s interior is in permanent sun shadow. SC stands for “same sense, circular”, OC stands for “opposite sense, circular” and CPR is the “circular polarization ratio.” The histogram of CPR values clearly shows that interior points (red line) have higher CPR values than those outside the crater rim (green line). The estimated amount of water ice potentially present is comparable to the quantity estimated solely from the previous mission of Lunar Prospector’s neutron data (several hundred million metric tons.) The variation in the estimates between Mini-SAR and the Lunar Prospector’s neutron spectrometer is due to the fact that it only measures to depths of about one-half meter, so it would underestimate the total quantity of water ice present. At least some of the polar ice is mixed with lunar soil and thus, invisible to our radar. “The emerging picture from the multiple measurements and resulting data of the instruments on lunar missions indicates that water creation, migration, deposition and retention are occurring on the moon,” said Paul Spudis, principal investigator of the Mini-SAR experiment at the Lunar and Planetary Institute in Houston. “The new discoveries show the moon is an even more interesting and attractive scientific, exploration and operational destination than people had previously thought.” “After analyzing the data, our science team determined a strong indication of water ice, a finding which will give future missions a new target to further explore and exploit,” said Jason Crusan, program executive for the Mini-RF Program for NASA’s Space Operations Mission Directorate in Washington. The Mini-SAR’s findings are being published in the journal Geophysical Research Letters. The results are consistent with recent findings of other NASA instruments and add to the growing scientific understanding of the multiple forms of water found on the moon. The agency’s Moon Mineralogy Mapper discovered water molecules in the moon’s polar regions, while water vapor was detected by NASA’s Lunar Crater Observation and Sensing Satellite, or LCROSS. Mini-SAR and Moon Mineralogy Mapper are two of 11 instruments on the Indian Space Research Organization’s Chandrayaan-1. The Applied Physics Laboratory in Laurel, Md., performed the final integration and testing on Mini-SAR. It was developed and built by the Naval Air Warfare Center in China Lake, Calif., and several other commercial and government contributors.

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA engineers will test a suite of new laser technologies from an aircraft this summer for Earth science remote sensing. Called lidar, the instruments could also be used to improve models of the Moon’s shape and aid the search for Artemis landing sites. Similar to sonar, but using light instead of sound, lidars calculate distances by timing how long a laser beam takes to reflect off a surface and return to an instrument. Multiple pings from the laser can provide the relative speed and even 3D image of a target. They increasingly help NASA scientists and explorers navigate, map, and collect scientific data. Engineers and scientists at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, continue to refine lidars into smaller, lighter, more versatile tools for science and exploration, with help from hardware provided by small business and academic partners. “Existing 3D-imaging lidars struggle to provide the 2-inch resolution needed by guidance, navigation and control technologies to ensure precise and safe landings essential for future robotic and human exploration missions,” team engineer Jeffrey Chen said. “Such a system requires 3D hazard-detection lidar and a navigation doppler lidar, and no existing system can perform both functions.” Engineer Jeffrey Chen tests a CASALS lidar prototype on the roof of Goddard’s Building 33.NASA Enter CASALS, the Concurrent Artificially intelligent Spectrometry and Adaptive Lidar System. Developed through Goddard’s IRAD, Internal Research and Development program, CASALS shines a tunable laser through a prism-like grating to spread the beam based on its changing wavelengths. Traditional lidars pulse a fixed-wavelength laser which is split into multiple beams by bulky mirrors and lenses to split it into multiple beams. One CASALS instrument could cover more of a planet’s surface in each pass than lidars used for decades to measure Earth, the Moon, and Mars. CASALS’s smaller size, weight, and lower power requirements enable small satellite applications as well as handheld or portable lidars for use on the Moon’s surface, Goddard engineer and CASALS development lead Guangning Yang said. The CASALS team received funding from NASA’s Earth Science Technology Office to test their improvements by airplane in 2024, bringing their system closer to spaceflight readiness. What Color is Your Lidar? As lidars become more specialized, CASALS can incorporate different wavelengths, or colors of laser light for applications like Earth science, exploring other planets and objects in space, and navigation and rendezvous operations. The CASALS Team used Goddard IRAD and NASA SBIR (Small Business Innovation Research Program) funding along with commercial partners Axsun Technologies and Freedom Photonics to develop new fast-tuning lasers in the 1-micron portion of the infrared spectrum for Earth science and planetary exploration. By comparison, commonly available lidars used for self-driving vehicle development typically use 1.5-micron lasers for range and speed calculations. On Earth, wavelengths near 1 micron pass readily through the atmosphere and are good at differentiating vegetation from bare ground, said Ian Adams, Goddard’s chief technologist for Earth sciences. Wavelengths near 0.97 and 1.45 microns offer valuable information about water vapor in Earth’s atmosphere but do not travel as efficiently to the surface. In a related project, the team partnered with Left Hand Design Corporation to develop a steering mirror to extend CASALS’s 3D-imaging coverage and improve resolution. He said the lidar’s higher pulse rate can build up signal sensitivity to provide range and velocity measurements at up to 60 miles. Artemis-related missions seeking to land near the Moon’s South Pole could also use CASALS’s sharper imaging to help assess the safety of potential landing sites. Bringing the Moon into Focus More detailed 3D models of the Moon drove Goddard planetary scientist Erwan Mazarico’s IRAD effort to refine CASALS’s ability to measure surface details smaller than 3 feet. He said this will help understand the Moon’s sub-surface structures and changes over time. Every month, Earth’s path across the lunar sky moves within 10 or 20 degrees of the center of the side facing Earth. “We’ve predicted based on our understanding of its inner structure that Earth’s shifting pull could change the tidal bulge or shape of the Moon,” Mazarico said. “High-resolution measurements of that deformation could tell us more about potential variations within the Moon. Is it responding like a fully uniform body in the interior?” Lunar Reconnaissance Orbiter’s Lunar Orbiting Laser Altimeter has produced detailed maps of the Lunar South Pole, including where water ice appears to fill the bottoms of permanently shadowed craters.NASA / LRO NASA’s Lunar Reconnaissance Orbiter (LRO) has measured Earth’s natural satellite since 2009, modeling the Moon’s terrain and providing a wealth of discoveries with the help of LOLA, its Lunar Orbiting Lidar Altimeter. LOLA fires 28 laser pulses per second, split into five beams touching the surface 65 feet to 100 feet apart. Scientists use LRO images to estimate smaller surface features between laser measurements. CASALS’s laser, however, allows the equivalent of several hundred thousand pulses per second, reducing the distance between surface measurements. “A denser and more accurate data set would allow us to study much smaller features,” Mazarico said, including those from impacts, volcanic activity, and tectonics. “We’re talking orders of magnitude more measurements. That could be quite a big game changer in terms of the type of data we get from lidar.” Read More Share Details Last Updated Mar 19, 2024 EditorKarl B.

5 min read Sketch the Shape of the Sun for Science During the Solar Eclipse Calling all eclipse admirers! The SunSketcher team is looking for one million volunteers to capture photos on their cell phones during the April 8 total solar eclipse. These images will help scientists learn about the size, shape, and inner structure of the Sun. This NASA-funded citizen science project invites anyone who will be within the path of totality in the U.S. to take photos of the Baily’s Beads effect, which occurs when little points of sunlight pass through the valleys in between the mountains on the edge of the Moon. It’s the last piece of the Sun seen before totality and the first to appear after totality. For a few seconds, these glimmers of light look like beads along the Moon’s edge. The Baily’s Beads effect is seen as the Moon makes its final move over the Sun during the total solar eclipse on Aug. 21, 2017, above Madras, Oregon. This effect occurs when gaps in the Moon’s rugged terrain allow sunlight to pass through in some places just before the total phase of the eclipse. NASA/Aubrey Gemignani The SunSketcher app will use smartphones to automatically take a sequence of images as Baily’s Beads appear. Volunteers will simply download a free app, activate it just before totality, set the phone down with the rear camera pointed at the Sun, and leave it alone. The app will use the phone’s GPS location to calculate when Baily’s Beads will be visible. “All you need is a cell phone,” says Gordon Emslie, SunSketcher’s project lead and professor of physics and astronomy at Western Kentucky University. “How many science projects can you do with the equipment you already have in your pocket?” Emslie says the cell phone images of Baily’s Beads will look fairly simple, but the tiny dots of light will provide crucial data about our star. “It’s the precise timing of when these flashes appear and disappear that can tell you how big the Sun is and what shape it is,” Emslie says. Citizen scientists will activate the Sunsketcher app before the eclipse and then prop their phone against a steady surface with the rear (back-facing) camera pointed at the Sun. The app will automatically take images of Baily’s Beads at the correct times. SunSketcher/Tabby Cline The SunSketcher team will merge the images collected from various viewpoints on the eclipse path to create an evolving pattern of beads. This pattern will be compared with 3D maps that show the exact locations and distances between lunar craters, mountains, and valleys on the surface of the Moon from NASA’s Lunar Reconnaissance Orbiter. The combined measurements will allow researchers to calculate the precise size and shape of the Sun based on the timing of the images captured over 90 minutes of eclipse observations. “The fascinating thing about this is you can really only do this by having observers stretched over the whole eclipse path,” Emslie explains. “No one observer can monitor an eclipse for more than about four or five minutes.” The Sun is round but not a perfect sphere. It bulges out slightly along the equator with a diameter of about 865,000 miles. Scientists suspect the shape of the Sun changes slightly as it goes through 11-year cycles of fluctuating solar activity. The Sun is a rotating ball of gas and plasma with complicated internal flows of material, energy, and magnetic fields beneath the surface that vary over that cycle and impact its overall shape. “All of these flows connect to the surface somehow, and so the shape of the surface is determined by the details of the flows,” Emslie says. “If we can understand the subsurface flows, we can better understand the Sun’s internal structure.” The Sun’s shape also determines its gravitational field, which affects the motions of the planets, so measuring the Sun’s precise shape will help scientists test theories of gravity. This map shows the path of totality and partial contours crossing the U.S. for the 2024 total solar eclipse occurring on April 8, 2024. NASA/Scientific Visualization Studio/Michala Garrison; Eclipse Calculations By Ernie Wright, NASA Goddard Space Flight Center Participants in the SunSketcher project can be located anywhere in the eclipse’s path of totality in the U.S., which stretches from Texas to Maine, on April 8. Emslie says the more people involved, the more worthwhile the project will be. “Literally, we’re looking for a million people to play.” For more info on SunSketcher, visit: https://sunsketcher.org/ How to Become a SunSketcher and Be a Part of History This animated tutorial from the SunSketcher team explains how volunteers can capture images during the total solar eclipse using a free cell phone app to help learn about the size, shape, and inner structure of the Sun. Animation credit: SunSketcher/Tabby Cline Before the Eclipse Download the free app from your phone’s app store (available now on iOS and coming soon on Android). Initiate the app around five minutes before totality. No internet connection is required. If possible, turn on “Do Not Disturb” in your phone’s settings to prevent vibrations that could disturb the image sequence. Prop the phone against a steady surface (such as a rock, book, phone stand, or tripod) with the rear (back-facing) camera pointed at the Sun. Let it be! The app will automatically take images of Baily’s Beads at the correct times. Enjoy the eclipse! Remember to use specialized eye protection for solar viewing except during the brief total phase of a total solar eclipse, when the Moon completely blocks the Sun. After the Eclipse The app will show a directory of images taken and will request user permission to share them. Only time and location data will be recorded with the images. No personally identifiable or private information will be collected. Once an internet connection is established, the images will be automatically uploaded to a central server and a screen will appear with a thank-you message.

Lunar scientist Casey Honniball conducts lunar observations and field work near volcanoes to investigate how astronauts could use instruments during moonwalks. Name: Casey Honniball Title: Lunar scientist Organization: Planetary Geology, Geophysics, and Geochemistry Laboratory, Science Directorate (Code 698) Casey Honniball is a lunar scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Courtesy of Casey Honniball What do you do and what is most interesting about your role here at Goddard? How do you help support Goddard’s mission? I study the Moon using Earth-based telescopes to understand the lunar volatile cycle. I also conduct field work at volcanic sites to investigate how astronauts can utilize instruments during moonwalks. Why did you want to be a lunar scientist? When I was 6 years old and in first grade, I was diagnosed with dyslexia. I was tutored and had help with homework and tests, which continued until I was a junior in high school. At that point, I learned to manage my dyslexia. Because I was not good at reading and writing, I turned to more physical things such as things I could touch and build. I discovered physics in high school, which turned me on to other sciences. I went to college for physics, but learned that I preferred astronomy. In graduate school I realized I wanted to be a lunar scientist. I have a B.S. in astronomy from the University of Arizona, a master’s in geology and geophysics from the University of Hawaiʻi at Manoa, and a Ph.D. in Earth and planetary science also from the University of Hawaiʻi at Manoa. While doing my master’s, one of my advisers introduced me to Earth-based lunar observation to look at hydration on the surface of the Moon. I found that I really liked the Moon and found my place in science. What brought you to Goddard? During graduate school, I worked with Goddard’s Dr. Kelsey Young on a field deployment testing instruments for astronauts. In 2020, I became a post-doctoral fellow for her at Goddard. In January 2023, I became a visiting assistant research scientist in the Planetary Geology, Geophysics, and Geochemistry Laboratory through CRESSTII, and Kelsey is still my mentor. As your mentor, what is the most important advice Kelsey Young has given you? Kelsey helps me stay passionate about the work I am doing. She does this by providing new and exciting opportunities and being supportive about work-life balance. I admire Kelsey’s spirit of adventure and her passion for field work. I appreciate all she has done for me and am grateful for the opportunities she and our lab have provided. Using Earth-based telescopes, Casey studies the Moon to understand the lunar volatile cycle. “While doing my master’s, one of my advisers introduced me to Earth-based lunar observation to look at hydration on the surface of the Moon,” said Casey. “I found that I really liked the Moon and found my place in science.”Courtesy of Casey Honniball What sorts of instruments do you test for use on the Moon? I test the use of mid- to long-wave infrared instruments for reconnaissance of a location prior to astronauts setting foot outside a vehicle. For example, an instrument on a rover can scan the area to characterize the minerology and volatiles including water, carbon dioxide, sulfur, methane, and similar chemicals. This then allows astronauts and scientists to select locations to collect samples. I test this procedure on Earth by doing field work. What is the most exciting field work you have done to test those instruments? In 2015, I went to the Atacama Desert in Chile to install a radio camera on an existing telescope. I spent about a month installing the camera and observing on the telescope. There were only about 15 people I interacted with during that time. The area is very Martian-like; it is very red, dry, and barren, although we saw wild donkeys. During Christmas of 2015 and again in 2016, one month each time, I went to Antarctica to launch a high-altitude balloon radio telescope. I lived at McMurdo Station and worked at their balloon facility near the airstrip. Antarctica is a completely different experience than you could imagine. You are so cut off from civilization. You have only the people who are there, although, I was there during Antarctica’s summer when McMurdo had many people. You are in a completely barren landscape that is so magnificently beautiful. In 2018, I deployed an instrument I built to the Kīlauea Lava Lake on the Big Island of Hawaii. This is a National Park with thousands of visitors yearly. The lava lake was active at the time. We could see lava spewing out at different vent locations in the lake. It was very exciting and kind of scary. We had special permits allowing us into restricted areas closer to the lake. We were told not to get any closer to the cliff edge of the lake than our height so that if we tripped, we would not fall into the active lava. I’d love to do field work in Iceland. Iceland is a great location for planetary field analog research as it has a similar landscape and geologic context to the Moon and Mars. Casey conducts field work at volcanic sites to investigate how astronauts can utilize instruments during moonwalks.Courtesy of Casey Honniball What outreach do you do that inspires others with dyslexia? I like to talk to elementary through high school students about life as a scientist and how I got to where I am. I like to tell my story about learning to manage dyslexia to hopefully inspire others. What do you do for fun? I am a deep-sea scuba certified diver. I mainly dove in Hawaii because I was living there. I also enjoy working out, hiking, baking sourdough bread, and being with my family. Where do you see yourself in five years? I hope to be supporting Artemis science operations on the surface of Moon and continuing to studying the Moon’s surface remotely and conducting research through field deployments. What is your “six-word memoir”? A six-word memoir describes something in just six words. Fear is a state of mind.

NASA Science Live: How to Prepare for the April 8 Total Solar Eclipse

2 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) In 2022, nearly 100 large wildland fires burned in the U.S. West. Almost two dozen of those burned Washington and Oregon alone, filling the air with smoke. Plumes from the fires often could easily be seen from space.Credit: NASA Globally, nearly all wildfires start with a human ignition source – not lightning strikes or wildlife encountering power equipment. Knowing humans can be a primary cause is an example of the sort of knowledge that helps predict and prevent wildfires, a challenge that NASA and the firefighting industry are undertaking together. As wildfires become more common in rarely experienced countries like Ireland and are more intense in other areas impacted by climate change, governments and businesses are turning to space for help. Landsat satellite Earth-observation data, artificial intelligence, and machine learning now predict and monitor fires and support post-fire recovery. San Diego-based Technosylva Inc. provides firefighters with a wildfire monitoring service that combines all these technologies. The company also uses other NASA fire data resources compiled by the agency’s Ames Research Center in Silicon Valley to assist during the fire season and beyond. Satellite imagery helps Technosylva’s Wildfire Analyst identify areas previously burned by wildfire to eliminate those areas without fuel like leaves or grasses (black circles) and pinpoint areas different types of available fuel (colored circles).Credit: Technosylva Inc. Technosylva uses data fusion, which integrates multiple data sources from climate, weather, landscapes, and human infrastructure, to develop a complete picture of current fire risks. Before fire season begins, these efforts help develop more resilient landscapes to make communities safer. During the fire season, models predict how fires will spread, and provide real-time equipment and personnel tracking across vast tracts of land. During the 2017 Las Máquinas wildfire in Chile – a fire so large the only way to view the perimeter was from space – Technosylva assisted in firefighting efforts by providing satellite data to help identify new hot spots and guided containment efforts.

A trio of astronauts visited with employees at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, on March 18, 2024, to share their spaceflight experiences aboard the International Space Station. NASA astronauts Stephen Bowen and Warren “Woody” Hoburg, and United Arab Emirates astronaut Sultan Alneyadi all served as flight engineers on the Expedition 69 crew aboard the International Space Station last year. Over 40 employees at NASA’s Goddard Space Flight Center in Greenbelt, Md., participated in a meet and greet with visiting astronauts on March 18, 2024. NASA astronaut Warren “Woody” Hoburg (left), United Arab Emirates astronaut Sultan Alneyadi, and NASA astronaut Stephen Bowen presented a video summarizing their mission before answering questions from Goddard staff.NASA/Tabatha Luskey The astronauts engaged with over 40 center employees during a meet and greet at the beginning of their visit. Employees viewed a 20-minute video that highlighted the astronauts’ preparation for the mission and their time in space. Afterward, they answered questions about daily life aboard the International Space Station. “These are people that you see growing up, and you hear about them, but to actually be in person with them is beyond words,” said Emily Wilson, an intern at Goddard. “It’s really awesome to hear their stories.” During their time in space, the Expedition 69 crew studied how materials burn in microgravity to understand spacecraft fire hazards, and they worked with technology to monitor how spaceflight stressors like microgravity and radiation impact the immune system. Bowen, Hoburg, and Alneyadi also completed spacewalks during the mission. Hoburg (left), Alneyadi, and Bowen view the construction of the Nancy Grace Roman Space Telescope from the clean room overlook in Goddard’s Building 29.NASA/Tabatha Luskey After their presentation to employees, the astronauts toured Goddard and heard from researchers about the exciting science and missions in work at the center. They listened to a presentation from Dr. Antti Pulkkinen, director of Goddard’s Heliophysics Science Division, and they visited the clean room where engineers are building the Nancy Grace Roman Space Telescope. Their time at Goddard concluded at the Hubble Space Telescope Operations Control Center. “The long history is really amazing, of all the contributions Goddard has made,” Hoburg said. “We’re truly going after those big fundamental questions about the origins of the universe, and all the kind of inspiring big scientific questions that drive us as humans, and it’s cool to see the contribution Goddard makes to all those big questions.” Learn more about NASA’s Expedition 69 at: https://www.nasa.gov/mission/expedition-69/ By Julia Tilton NASA’s Goddard Space Flight Center, Greenbelt, Md.

An engineering geologist measures water depth at an agricultural well in a field north of Sacramento, California. Groundwater is an important source of water for irrigation in the state’s Central Valley, especially during times of drought, and the GRACE missions provide data that helps track the resource.Kelly M. Grow/California Department of Water Resources The Gravity Recovery and Climate Experiment-Continuity mission will extend a decades-long record of following shifting water masses using gravity measurements. NASA and the German Space Agency at DLR (German Aerospace Center) have agreed to jointly build, launch, and operate a pair of spacecraft that will yield insights into how Earth’s water, ice, and land masses are shifting by measuring monthly changes in the planet’s gravity field. Tracking large-scale mass changes – showing when and where water moves within and between the atmosphere, oceans, underground aquifers, and ice sheets – provides a view into Earth’s water cycle, including changes in response to drivers like climate change. With the international agreement signed in late 2023, the Gravity Recovery and Climate Experiment-Continuity (GRACE-C) mission will extend a nearly 25-year legacy that began with the 2002 launch of the GRACE mission. The GRACE-Follow On (GRACE-FO) mission succeeded GRACE in 2018. GRACE-C is targeting a launch no earlier than 2028. The data from the GRACE missions is considered key information in characterizing Earth’s climate. Those measurements, together with other information and computer models, are regularly used for drought assessment and forecasting, water-use planning for agriculture, and understanding the drivers of sea level rise, such as how much ice the world’s ice sheets are losing. “GRACE-C represents an international and collaborative effort to observe and study one of our planet’s most precious resources,” said Nicola Fox, associate administrator for science at NASA in Washington. “From our coastlines to our kitchen tables, there is no aspect of our planet that is not impacted by changes in the water cycle. The partnership between NASA and the German Aerospace Center will serve a critical role in preparing for the challenges we face today and tomorrow.” Explore the GRACE-FO mission in NASA's Eyes on the Earth Engineers and scientists are finalizing design details for the instruments and satellites, and then teams will start work on fabricating and building. The mission will be composed of a pair of identical satellites flying one behind the other, roughly 60 to 190 miles (100 to 300 kilometers) apart, in a polar orbit. The spacecraft will fly at an altitude of roughly 300 miles (500 kilometers). Together they will monitor monthly changes to the distribution of water on Earth from variations in the planet’s gravity field. Following the Water The pull of gravity varies naturally from place to place on Earth depending on the mass distribution near the surface. For instance, large shifts in underground water storage (groundwater) or losses from ice sheets move a great amount of mass around, which can in turn shift the planet’s gravity field on weekly to monthly time scales. Researchers can gauge those changes by measuring very small changes in the distance between the two GRACE-C satellites. As the lead spacecraft flies over an area with relatively more mass – like a spot with more groundwater than its surroundings – the slight increase in Earth’s gravity field pulls the satellite forward, increasing its distance from the trailing spacecraft. Capable of measuring distance changes 100 times smaller than the thickness of a human hair, a laser ranging interferometer (LRI) instrument continually measures the distance between the two spacecraft. The satellite systems and orbit for GRACE-C will be similar to those of GRACE-FO, ensuring the continuity of measurements between the two missions. “GRACE-C will build on decades of observations of the global movement of water and changes in water resources. This is critical to informing predictions of future trends in our climate and to assess food and water security,” said Frank Webb, GRACE-C project scientist at NASA’s Jet Propulsion Laboratory in Southern California. “The mission is an example of the commitment that NASA and our German partners share for studying the Earth and helping society better prepare for a warming world.” GRACE-C, previously known as the Mass Change mission, addresses one of the key goals outlined in the 2017 Decadal Survey for Earth Science conducted by the U.S. National Academies of Science, Engineering, and Medicine: to better understand the planet’s global water cycle through large-scale changes in Earth’s mass. “Together with NASA, we are now continuing along the GRACE route in Earth observation, thereby strengthening our international cooperation in space-based research,” said Walther Pelzer, a member of the DLR executive board and director general of the German Space Agency at DLR. “The USA and Germany have been working closely together for a long time on climate and environmental research from space. The trust that our U.S. partners are placing in German space expertise for these missions by commissioning the satellite construction and the delivery of important parts of the GRACE-C instrumentation and mission control is also a sign of Germany’s capabilities as a prime location for spaceflight.” The mission will be part of NASA’s Earth System Observatory (ESO), a set of Earth-focused missions that will provide data to guide efforts related to climate change, natural hazard mitigation, wildfire management, and food security. When combined, ESO mission data will create a holistic view of Earth from the planet’s atmosphere to its bedrock. More About the Mission JPL manages the GRACE-C mission for NASA and will procure the two spacecraft from Airbus Defence and Space, the company that built the satellites for the GRACE and GRACE-FO missions. Development and construction of the LRI system will be led by JPL, which is managed for NASA by Caltech in Pasadena. The German contributions are funded by the German Federal Ministry of Economic Affairs and Climate Action and the Federal Ministry of Education and Research. The German Space Agency at DLR will manage the German contributions to GRACE-C, providing the LRI optics subsystems; mission operations; telemetry, tracking, and command; the ground data system; the laser retroreflectors to help with satellite positioning; the launch vehicle; and launch services.

NASA Astronauts Thomas P. Stafford (left), and Walter M. Schirra Jr., pose for the camera during suiting up exercises on Oct. 22, 1965. Stafford was selected among the second group of astronauts in September 1962 by NASA to participate in Projects Gemini and Apollo. In December 1965, he piloted Gemini VI, which made the first rendezvous in space with Gemini VII, and helped develop techniques to prove the basic theory and practicality of space rendezvous. In June 1966, Stafford commanded the Gemini IX mission and performed a demonstration of an early rendezvous that would be used in the Apollo lunar missions, the first optical rendezvous, and a lunar orbit abort rendezvous. He was also commander of Apollo 10 in May 1969; he descended to nine miles above the Moon, performing the entire lunar landing mission except the actual landing. He logged his fourth spaceflight as Apollo commander of the Apollo-Soyuz mission in July 1975, which culminated in the historic first meeting in space between American astronauts and Soviet cosmonauts.

The asteroid Dimorphos was captured by NASA’s DART mission just two seconds before the spacecraft struck its surface on Sept. 26, 2022. Observations of the asteroid before and after impact suggest it is a loosely packed “rubble pile” object.NASA/Johns Hopkins APL After NASA’s historic Double Asteroid Redirection Test, a JPL-led study has shown that the shape of asteroid Dimorphos has changed and its orbit has shrunk. When NASA’s DART (Double Asteroid Redirection Test) deliberately smashed into a 560-foot-wide (170-meter-wide) asteroid on Sept. 26, 2022, it made its mark in more ways than one. The demonstration showed that a kinetic impactor could deflect a hazardous asteroid should one ever be on a collision course with Earth. Now a new study published in the Planetary Science Journal shows the impact changed not only the motion of the asteroid, but also its shape. DART’s target, the asteroid Dimorphos, orbits a larger near-Earth asteroid called Didymos. Before the impact, Dimorphos had a roughly symmetrical “oblate spheroid” shape – like a squashed ball that is wider than it is tall. With a well-defined, circular orbit at a distance of about 3,900 feet (1,189 meters) from Didymos, Dimorphos took 11 hours and 55 minutes to complete one loop around Didymos. “When DART made impact, things got very interesting,” said Shantanu Naidu, a navigation engineer at NASA’s Jet Propulsion Laboratory in Southern California, who led the study. “Dimorphos’ orbit is no longer circular: Its orbital period” – the time it takes to complete a single orbit – “is now 33 minutes and 15 seconds shorter. And the entire shape of the asteroid has changed, from a relatively symmetrical object to a ‘triaxial ellipsoid’ – something more like an oblong watermelon.” This illustration shows the approximate shape change that the asteroid Dimorphos experienced after DART hit it. Before impact, left, the asteroid was shaped like a squashed ball; after impact it took on a more elongated shape, like a watermelon.NASA/JPL-Caltech Dimorphos Damage Report Naidu’s team used three data sources in their computer models to deduce what had happened to the asteroid after impact. The first source was aboard DART: The spacecraft captured images as it approached the asteroid and sent them back to Earth via NASA’s Deep Space Network (DSN). These images provided close-up measurements of the gap between Didymos and Dimorphos while also gauging the dimensions of both asteroids just prior to impact. The second data source was the DSN’s Goldstone Solar System Radar, located near Barstow, California, which bounced radio waves off both asteroids to precisely measure the position and velocity of Dimorphos relative to Didymos after impact. Radar observations quickly helped NASA conclude that DART’s effect on the asteroid greatly exceeded the minimum expectations. The third and most significant source of data: ground telescopes around the world that measured both asteroids’ “light curve,” or how the sunlight reflecting off the asteroids’ surfaces changed over time. By comparing the light curves before and after impact, the researchers could learn how DART altered Dimorphos’ motion. As Dimorphos orbits, it periodically passes in front of and then behind Didymos. In these so-called “mutual events,” one asteroid can cast a shadow on the other, or block our view from Earth. In either case, a temporary dimming – a dip in the light curve – will be recorded by telescopes. See the DART impact with NASA’s Eyes on the Solar System “We used the timing of this precise series of light-curve dips to deduce the shape of the orbit, and because our models were so sensitive, we could also figure out the shape of the asteroid,” said Steve Chesley, a senior research scientist at JPL and study co-author. The team found Dimorphos’ orbit is now slightly elongated, or eccentric. “Before impact,” Chesley continued, “the times of the events occurred regularly, showing a circular orbit. After impact, there were very slight timing differences, showing something was askew. We never expected to get this kind of accuracy.” The models are so precise, they even show that Dimorphos rocks back and forth as it orbits Didymos, Naidu said. Orbital Evolution The team’s models also calculated how Dimorphos’ orbital period evolved. Immediately after impact, DART reduced the average distance between the two asteroids, shortening Dimorphos’ orbital period by 32 minutes and 42 seconds, to 11 hours, 22 minutes, and 37 seconds. Over the following weeks, the asteroid’s orbital period continued to shorten as Dimorphos lost more rocky material to space, finally settling at 11 hours, 22 minutes, and 3 seconds per orbit – 33 minutes and 15 seconds less time than before impact. This calculation is accurate to within 1 ½ seconds, Naidu said. Dimorphos now has a mean orbital distance from Didymos of about 3,780 feet (1,152 meters) – about 120 feet (37 meters) closer than before impact. “The results of this study agree with others that are being published,” said Tom Statler, lead scientist for solar system small bodies at NASA Headquarters in Washington. “Seeing separate groups analyze the data and independently come to the same conclusions is a hallmark of a solid scientific result. DART is not only showing us the pathway to an asteroid-deflection technology, it’s revealing new fundamental understanding of what asteroids are and how they behave.” These results and observations of the debris left after impact indicate that Dimorphos is a loosely packed “rubble pile” object, similar to asteroid Bennu. ESA’s (European Space Agency) Hera mission, planned to launch in October 2024, will travel to the asteroid pair to carry out a detailed survey and confirm how DART reshaped Dimorphos. More About the Mission DART was designed, built, and operated by the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, for NASA’s Planetary Defense Coordination Office, which oversees the agency’s ongoing efforts in planetary defense. DART was humanity’s first mission to intentionally move a celestial object.

Teams prepare for a playoff match at the L.A. regional FIRST Robotics Competition in El Segundo on March 17. The robots, built by high school teams, would go on to face off with three other robots being staged at the other end of the playing field.NASA/JPL-Caltech The robots clash six at a time – in two alliances of three robots – on a playing field of about 54 feet by 26 feet in the FIRST Robotics Competition. The human competitors can sport color-coordinated outfits, face paint, and pompoms.NASA/JPL-Caltech The winning alliance poses at the Los Angeles regional FIRST Robotics Competition on March 17. From left, Team 9408 (“Warbots”) of Warren High in Downey, Team 368 (“Team Kika Mana”) of McKinley High School in Honolulu, and Team 980 (“ThunderBots”) of Burbank and Burroughs high schools in Burbank. Credit: NASA/JPL-Caltech Hand-crafted robots, constructed over the past two months by 44 high school teams, duked it out at the FIRST Robotics Los Angeles regional competition. Student-made contraptions of a metal and a little magic battled each other in front of cheering and dancing high schoolers at the annual Los Angeles regional FIRST Robotics Competition over the weekend, an event supported by NASA’s Jet Propulsion Laboratory. Of the 44 participating teams, five triumphed, earning the chance to compete this April at the FIRST international championship tournament in Houston. The raucous event at the Da Vinci Schools campus in El Segundo saw six 125-pound robots racing around the playing field during each 2 ½-minute match as pounding music filled the room and a live announcer narrated the action. Working in alliances of three teams on each side, the robots jockeyed for position and banged into each other, using a variety of mechanical devices to retrieve large, foam rings from the floor and launch them into two target chutes. In the final seconds of each round, the bots could earn extra points by hoisting themselves off the ground to dangle from a metal chain. “The energy in the room was amazing this year,” said Kim Lievense, the manager of JPL’s Public Services Office, who coordinates some 100 volunteers for the event every year. “These teams and their bots really left it all on the field, and it was so great to be there to see it yet again.” The 24th year for this L.A.-area competition, the event is one of many under the umbrella of the nonprofit FIRST (For Inspiration and Recognition of Science and Technology), which pairs students with STEM professionals. The competitions give students hands-on experience with engineering and problem-solving, team-building, fundraising, and other business skills. Teams receive the rules of the game – titled “Crescendo” this year and themed around arts and entertainment – in January. Using FIRST’s technical specifications, students have just weeks to design, build, and test their robots, devoting hours after school and on weekends to the project. “There were a lot of really impressive robots, and students, this year. The engineering, the manufacturing, the programming in the software these kids are writing – it’s quite complex,” said Julie Townsend, one of three event judges from JPL. She has been volunteering with FIRST for nearly 20 years as a judge and coach and is JPL’s point of contact for the NASA Robotics Alliance Project, which supports NASA “house” youth robotics teams across the country. “Without these programs like FIRST, high school students don’t have the opportunity to do this kind of engineering,” Townsend added. “It’s hard, but they eventually get to experience the joy of a functioning system that you designed. You failed 16 times and then you get to see it work flawlessly.” In the end, the winning alliance joined together a team from Hawaii with two Southern California teams: Team 368 (“Team Kika Mana”) of McKinley High School in Honolulu, Team 9408 (“Warbots”) of Warren High in Downey, and Team 980 (“ThunderBots”) of Burbank and Burroughs high schools in Burbank, which is a NASA house team supported by JPL. Two other L.A.-area teams won awards that mean they’ll get to compete in Houston as well: Team 687 (“The Nerd Herd”) of California Academy of Math and Science in Carson, and Team 3473 (“Team Sprocket”) of Diamond Bar High.

(1966) — Portrait of astronaut Thomas P. Stafford, wearing his spacesuit.Credits: NASA The following is a statement from NASA Administrator Bill Nelson on Monday’s passing of Thomas Stafford, a lifelong space exploration advocate, former NASA astronaut, and U.S. Air Force general: “Today, General Tom Stafford went to the eternal heavens, which he so courageously explored as a Gemini and Apollo astronaut as well as a peacemaker in the Apollo-Soyuz mission. Those of us privileged to know him are very sad but grateful we knew a giant. “Tom was critical to the earliest successes of our nation’s space program and was instrumental in developing space as a model for international cooperation. He also helped us learn from our tragedies and grow and reach for the next generation of achievement. He was intimately involved with the space program, sharing his thoughts and suggestions on NASA missions until the end of his life. “Tom was a gentleman and a daredevil. He flew our first rendezvous in space on Gemini 6, and piloted Gemini 9’s path to Earth with pencil and paper when the spacecraft’s guidance computer failed in orbit. He commanded Apollo 10, the first flight of the lunar module to the Moon, a critical test flight that resulted in the successful landing on the Moon during the Apollo 11 mission. Tom also flew more than 100 different types of aircraft throughout his career as he pushed the edge of the envelope of our achievement in air and space. He was an extraordinary peacemaker who commanded NASA’s first rendezvous of an international spacecraft on the Apollo-Soyuz mission. His counterpart, General Alexei Leonov, became a best friend over the years. Tom gave Alexei’s eulogy in 2019 at the Russian state funeral. “Tom’s dedication to NASA never wavered. In later years, he chaired a team to independently advise NASA on how to carry out President H.W. Bush’s space policy and completed the study ‘America at the Threshold’ about the nation’s potential future with humans in space. He also was co-chairman of the Stafford-Covey Space Shuttle Return to Flight Task Group that assessed NASA’s implementation of the Columbia Accident Investigation Board Space Shuttle Return to Flight recommendations. “Our nation will be forever grateful to an explorer who never lost his sense of wonder. About his time in space, he said, ‘It changes you, oh sure. Changes your outlook…As you look back, you see a little blue and white baseball, actually, it’s smaller than a baseball. But it’s hard to envision that is where all the people you’ve known all your life are, where you went to school, your friends, your family. It’s also hard to envision that there are three billion people on that blue and white baseball.’ “Godspeed, Tom Stafford.” For more information about Stafford’s NASA career, and his agency biography, visit: https://www.nasa.gov/former-astronaut-thomas-stafford/ -end- Faith McKie / Cheryl Warner Headquarters, Washington 202-358-1600 faith.d.mckie@nasa.gov / cheryl.m.warner@nasa.gov Share Details Last Updated Mar 18, 2024 LocationNASA Headquarters Related TermsThomas P.

NASA’s Office of STEM Engagement has selected seven student teams to participate in a culminating event for the 2024 App Development Challenge (ADC), one of the agency’s Artemis Student Challenges, at NASA’s Johnson Space Center in Houston. The coding challenge invites middle and high school student teams to contribute to deep space exploration missions by developing solutions to real-world technical problems. Screenshot of the app submitted by ADC Top Team, Team Spaghetti Code from Trinity Christian School in Morgantown, West Virginia. The ADC, a part of NASA’s Next Gen STEM project, gives students an opportunity to participate in NASA’s endeavors to land American astronauts, including the first woman and the first person of color, on the Moon. Artemis Generation students are prompted to create an application to visualize the Moon’s South Pole region and display essential information for navigating the lunar surface and receiving signals from Earth. NASA will make history by sending the first humans to explore the region near the lunar South Pole on Artemis III. “Working on this application gave us a simplified understanding and real-world experience of how professionals approach similar problems in the work-field,” stated Team Frostbyte, from North High School in Des Moines, Iowa, “Engaging in this hands-on project has deepened our passion for innovative utilization of technology. Our participation in this challenge has only further affirmed our goals to pursue careers in these fields.” Over the 10-week challenge, participating teams joined subject matter expert talks, attended ADC office hours, researched lunar landing regions and mathematical concepts, and spent hundreds of hours coding to develop their applications. Additionally, students learned about the complexities of communicating from the lunar surface with Earth-based assets from NASA’s Space Communications and Navigation (SCaN) team. The following five teams excelled in their application and interview, thereby earning the chance to showcase their work to NASA leadership, tour NASA’s unique facilities, and meet industry leaders, in April 2024 at NASA Johnson: Baton Rouge Magnet High School: Baton Rouge, Louisiana Dougherty Valley High School: San Ramon, California North High School: Des Moines, Iowa Sherman Oaks Center for Enriched Studies: Reseda, California Trinity Christian School: Morgantown, West Virginia In addition, two more schools were selected as honorable mentions to present their work virtually to NASA leadership in April 2024.
