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 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 above 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.
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 (one meter) 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 Dr. John Carr, deputy center chief technologist at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “These capabilities are critical for achieving higher value science alongside the exploration of deep space with small spacecraft.”
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. NASA’s Marshall Space Flight Center in Huntsville, Alabama 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 in California’s Silicon Valley 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 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. To travel farther into deep space, small spacecraft require more electrical power than what is currently available through existing technology. LISA-T aims to answer that demand and would offer small spacecraft access to power without compromising mass or volume.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The Skydweller Aero solar-powered, autonomous aircraft flies above the Thad Cochran Test Stand (B-1/B-2) at NASA’s Stennis Space Center during a September 2024 test operation. Skydweller Aero has an ongoing airspace agreement with NASA Stennis to conduct test flights of its aircraft in the area.Skydweller Aero NASA’s Stennis Space Center near Bay St. Louis, Mississippi, has entered into an agreement with Skydweller Aero Inc. for the company to operate its solar-powered autonomous aircraft in the site’s restricted airspace, a key step towards achieving a strategic center goal.
The Reimbursable Space Act agreement marks the first between NASA Stennis and a commercial company to utilize the south Mississippi center’s unique capabilities to support testing and operation of uncrewed systems.
“There are few locations like NASA Stennis that offer a secure location, restricted airspace and the infrastructure to support testing and operation of various uncrewed systems,” said NASA Stennis Director John Bailey. “Range operations is a critical area of focus as we adapt to the changing aerospace and technology landscape to grow into the future.”
NASA Stennis and Skydweller Aero finalized the agreement in late August, paving the way for the company to begin area test flights of its autonomous, uncrewed solar-powered aircraft, which features a wingspan greater than a 747 jetliner and is designed for long-duration flights. The company announced Oct. 1 it had completed an initial test flight campaign of the aircraft, including two test excursions totaling 16 and 22.5 hours.
NASA Stennis and Skydweller Aero began talks in the summer of 2023 when the company expressed interest in utilizing NASA Stennis airspace for its all-carbon fiber aircraft. The NASA Stennis area fits the company’s needs well since it provides ready access from Stennis International Airport to the Gulf of Mexico area. NASA Stennis airspace also provides a level of privacy for aircraft testing and operation.
“Access to the restricted airspace above NASA Stennis has been tremendously helpful to our uncrewed, autonomous flight operations,” said Barry Matsumori, president and chief operating officer of Skydweller Aero. “The opportunity to use the controlled environment above Stennis helps accelerate our efforts, allowing us to transition the aircraft in and out of civil airspace, while demonstrating its reliability and unblemished safety record to the FAA.”
Companies must be conducting public aircraft operations to use any restricted airspace. In this instance, Skydweller Aero is flying its aircraft in association with the U.S. Department of Defense, allowing for the Reimbursable Space Act agreement with NASA Stennis.
The agreement provides the company Federal Aviation Administration (FAA) authorization for future test flights in designated areas of the NASA Stennis buffer zone. It also represents a key step in the center’s effort to grow its range operations presence.
“This really opens the door for others to come here,” said Jason Peterson, NASA Stennis range officer. “There are requirements that must be met, but for those who meet them, NASA Stennis is an ideal location for test and flight operations.”
The FAA established restricted airspace at NASA Stennis in 1966 and approved its expansion in 2016. The expansion was necessary to conduct propulsion testing safely, accommodate U.S. Department of Defense missions, and support unmanned aerial systems activities.
Restricted airspace at NASA Stennis allows qualifying organizations to conduct various uncrewed flight activities. NASA Stennis personnel provide scheduling and range operation support, including reviews and evaluations to ensure safe flight operations. Processes are in place to ensure communication between aircraft operators, FAA air traffic controllers, and range safety personnel.
Peterson said he hopes the agreement with Skydweller Aero will clear the way for future collaborations as NASA Stennis continues to expand its customer-based operations. For instance, although Skydweller Aero is not located onsite, NASA Stennis is able to support ground operations for a variety of unmanned aircraft system takeoffs and landings.
Beyond that, the center also hopes to expand its operational capabilities to include marine and ground activities. In addition to a large geographic footprint, the center features a secure 7.5-mile waterway canal system for testing unmanned underwater or surface vehicles.

Microgravity had no immediate effect on a person’s ability to perceive the height of an object, indicating that astronauts can safely perform tasks that rely on accurate and precise height judgments soon after arrival in space.
We use the height and width of objects around us to complete tasks such as reaching for objects and deciding whether we can fit through an opening. VECTION, an investigation from the Canadian Space Agency, examined the effect of microgravity on an astronaut’s visual perception and how that ability may adapt during flight or upon return to Earth. Researchers conclude there is no need for countermeasures but suggest that space travelers be made aware of late-emerging and potentially long-lasting changes in the ability to perceive object height.
Canadian Space Agency astronaut David Saint-Jacques conducts a session for the VECTION experiment. NASA/Anne McClain Analysis of the genomes of five new species of bacteria found on the International Space Station identified specific adaptations to space, including the development of increased antibiotic resistance and a greater potential for causing diseases. The genes that facilitate these adaptations could serve as potential targets for drugs, helping to protect crew health on future missions.
Microbial Tracking-2 monitored viruses, bacteria, and fungi on the space station to catalog and characterize any with the potential to cause disease. Understanding the mechanisms behind adaptations to space could advance development of ways to protect crew member health as well as spacecraft and equipment on future missions. Microbial adaptations also have potential applications in biotechnology, such as engineering more resilient organisms for use in space and extraterrestrial environments.
A Microbial Tracking-2 sample collector on the International Space Station. NASA/Jack Fischer When NASA’s Airborne Lightning Observatory for Fly’s Eye and the space station’s ASIM instrument briefly passed over the same geographic area, the airborne instrument detected terrestrial gamma‐ray flashes (TGFs) that were not detected by ASIM. TGFs are short bursts of gamma‐rays produced by lightning in thunderclouds. This result suggests that a significant number of TGFs are too weak to be observed from space and that the percentage of lightning associated with these phenomena may be higher than previously thought.
ASIM, an investigation from the European Space Agency, studies high-altitude lightning in thunderstorms and the role it plays in Earth’s atmosphere and climate. Results could help scientists develop better atmospheric models to guide weather and climate prediction and response. The airborne instrument took measurements at an altitude of about 12 miles and ASIM at approximately 260 miles above Earth’s surface.

On Oct. 18, 1989, space shuttle Atlantis took off on its fifth flight, STS-34, from NASA’s Kennedy Space Center (KSC) in Florida. Its five-person crew of Commander Donald E. Williams, Pilot Michael J. McCulley, and Mission Specialists Shannon W. Lucid, Franklin R. Chang-Díaz, and Ellen S. Baker flew a five-day mission that deployed the Galileo spacecraft, managed by NASA’s Jet Propulsion Laboratory in Southern California, to study Jupiter. The astronauts deployed Galileo and its upper stage on their first day in space, sending the spacecraft on its six-year journey to the giant outer planet. Following its arrival at Jupiter in December 1995, Galileo deployed its atmospheric probe while the main spacecraft entered orbit around the planet, studying it in great detail for eight years.

Middle: The STS-34 crew patch. Right: The Galileo spacecraft in Atlantis’ payload bay in preparation for STS-34.
In November 1988, NASA announced Williams, McCulley, Lucid, Chang-Díaz, and Baker as the STS-34 crew for the flight planned for October 1989. Williams and Lucid, both from the Class of 1978, had each flown once before, on STS-51D in April 1985 and STS-51G in June 1985, respectively. Chang-Díaz, selected in 1980, had flown once before on STS-61C in January 1986, while for McCulley and Baker, both selected in 1984, STS-34 represented their first spaceflight. During their five-day mission, the astronauts planned to deploy Galileo and its Inertial Upper Stage (IUS) on the first flight day. Following the Galileo deployment, the astronauts planned to conduct experiments in the middeck and the payload bay.

Following the successful Pioneer and Voyager flyby missions, NASA’s next step to study Jupiter in depth involved an ambitious orbiter and atmospheric entry probe. NASA first proposed the Jupiter Orbiter Probe mission in 1975, and Congress approved it in 1977 for a planned 1982 launch on the space shuttle. In 1978, NASA renamed the spacecraft Galileo after the 17th century Italian astronomer who turned his new telescope toward Jupiter and discovered its four largest moons. Delays in the shuttle program and changes in the upper stage to send Galileo from low Earth orbit on to Jupiter resulted in the slip of its launch to May 1986, when on Atlantis’ STS-61G mission, a Centaur upper stage would send the spacecraft toward Jupiter.
The January 1986 Challenger accident not only halted shuttle flights for 31 months but also canceled the Centaur as an upper stage for the orbiter. Remanifested onto the less powerful IUS, Galileo would require gravity assist maneuvers at Venus and twice at Earth to reach its destination, extending the transit time to six years. Galileo’s launch window extended from Oct. 12 to Nov. 21, 1989, dictated by planetary alignments required for the gravity assists. During the transit, Galileo had the opportunity to pass by two main belt asteroids, providing the first closeup study of this class of objects. Upon arrival at Jupiter, Galileo would release its probe to return data as it descended through Jupiter’s atmosphere while the main spacecraft would enter an elliptical orbit around the planet, from which it would conduct in depth studies for a minimum of 22 months.

The Galileo atmospheric probe arrived at KSC on April 17 and the main spacecraft on May 16, following which workers joined the two together for preflight testing. Meanwhile, Atlantis returned to KSC on May 15, following the STS-30 mission that deployed the Magellan spacecraft to Venus. The next day workers towed it into the Orbiter Processing Facility to prepare it for STS-34. In KSC’s Vehicle Assembly Building (VAB), workers began stacking the Solid Rocket Boosters (SRB) on June 15, completing the activity on July 22, and then adding the External Tank (ET) on July 30. Atlantis rolled over to the VAB on Aug. 22 for mating with the ET and SRBs. Galileo, now mated to its IUS, transferred to Launch Pad 39B on Aug. 25, awaiting Atlantis’ arrival four days later.
The next day, workers placed Galileo into Atlantis’ payload bay and began preparations for the Oct. 12 launch. The Terminal Countdown Demonstration Test took place on Sept. 14-15, with the astronauts participating in the final few hours as on launch day. A faulty computer aboard the IUS threatened to delay the mission, but workers replaced it without impacting the planned launch date. The five-member astronaut crew arrived at KSC Oct. 9 for final preparations for the flight and teams began the countdown for launch. A main engine controller problem halted the countdown at T minus 19 hours. The work required to replace it pushed the launch date back to Oct. 17. On that day, the weather at the pad supported a launch, but clouds and rain at the Shuttle Landing Facility several miles away, and later rain at a Transatlantic (TAL) abort site, violated launch constraints, so managers called a 24-hour scrub. The next day, the weather cooperated at all sites, and other than a brief hold to reconfigure Atlantis’ computers from one TAL site to another, the countdown proceeded smoothly.

Atlantis lifted off Launch Pad 39B at 12:53 p.m. EDT on Oct. 18. As soon as the shuttle cleared the launch tower, control shifted to the Mission Control Center at NASA’s Johnson Space Center in Houston, where Ascent Flight Director Ronald D. Dittemore and his team of controllers, including astronaut Frank L. Culbertson serving as the capsule communicator, or capcom, monitored all aspects of the launch. Following main engine cutoff, Atlantis and its crew had achieved orbit. Forty minutes later, a firing of the two Orbital Maneuvering System (OMS) engines circularized the orbit at 185 miles. The astronauts removed their bulky Launch and Entry Suits (LES) and prepared Atlantis for orbital operations, including opening the payload bay doors.

Preparations for Galileo’s deployment began shortly thereafter. In Mission Control, Flight Director J. Milton Heflin and his team, including capcom Michael A. Baker, took over to assist the crew with deployment operations. The astronauts activated Galileo and the IUS, and ground teams began checking out their systems, with the first TV from the mission showing the spacecraft and its upper stage in the payload bay. Lucid raised Galileo’s tilt table first to 29 degrees, McCulley oriented Atlantis to the deployment attitude, then Lucid raised the tilt table to the deploy position of 58 degrees. With all systems operating normally, Mission Control gave the go for deploy.
Six hours and 20 minutes into the mission, Lucid deployed the Jupiter-bound spacecraft and its upper stage, weighing a combined 38,483 pounds. “Galileo is on its way to another world,” Williams called down. The combination glided over the shuttle’s crew compartment. Williams and McCulley fired the two OMS engines to move Atlantis a safe distance away from the IUS burn that took place one hour after deployment, sending Galileo on its circuitous journey through the inner solar system before finally heading to Jupiter. The primary task of the mission accomplished, the astronauts prepared for their first night’s sleep in space.

For the next three days, the STS-34 astronauts focused their attention on the middeck and payload bay experiments, as well as taking photographs of the Earth. Located in the payload bay, the Shuttle Solar Backscatter Ultraviolet experiment, managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland, measured ozone in the Earth’s atmosphere and compared the results with data obtained by weather satellites at the same locations. The comparisons served to calibrate the weather satellite instruments. Baker conducted the Growth Hormone Concentrations and Distributions in Plants experiment, that investigated the effect of the hormone Auxin in corn shoot tissue. Three days into the mission, she placed plant canisters into a freezer to arrest plant growth and for postflight analysis. Chang-Díaz and Lucid had prime responsibility for the Polymer Morphology experiment, developed by the 3M Company. They used a laptop to control experiment parameters as the hardware melted different samples to see the effects of weightlessness. Baker conducted several medical investigations, including studying blood vessels in the retina, changes in leg volume due to fluid shifts, and carotid blood flow.

On Oct. 23, the astronauts awakened for their final day in space. Because of high winds expected at the primary landing site at Edwards Air Force Base (AFB), managers moved the landing up by two revolutions. In preparation for reentry, the astronauts donned their orange LESs and closed the payload bay doors. Williams and McCulley oriented Atlantis into the deorbit attitude, with the OMS engines facing in the direction of travel. Over the Indian Ocean, they fired the two engines for 2 minutes 48 seconds to bring the spacecraft out of orbit. They reoriented the orbiter to fly with its heat shield exposed to the direction of flight as it encountered Earth’s atmosphere at 419,000 feet. The buildup of ionized gases caused by the heat of reentry prevented communications for about 15 minutes but provided the astronauts a great light show. The entry profile differed slightly from the planned one because Atlantis needed to make up 500 miles of cross range since it returned two orbits early. After completing the Heading Alignment Circle turn, Williams aligned Atlantis with the runway, and McCulley lowered the landing gear. Atlantis touched down and rolled to a stop, ending a 4-day 23-hour 39-minute flight, having completed 79 orbits of the Earth. Following postlanding inspections, workers placed Atlantis atop a Shuttle Carrier Aircraft, a modified Boeing-747, and the combination left Edwards on Oct. 28. Following refueling stops at Biggs Army Airfield in Texas and Columbus AFB in Mississippi, Atlantis and the SCA arrived back at KSC on Oct. 29. Workers began to prepare it for its next flight, STS-36 in February 1990.

One hour after deployment from Atlantis, the IUS ignited to send Galileo on its six-year journey to Jupiter, with the spacecraft flying free of the rocket stage 47 minutes later. The spacecraft’s circuitous path took it first to Venus on Feb. 10, 1990, back to Earth on Dec. 8, 1990, and again on Dec. 8, 1992, each time picking up velocity from the gravity assist to send it on to the giant planet. Along the way, Galileo also passed by and imaged the main belt asteroids Gaspra and Ida and observed the crash of Comet Shoemaker-Levy 9 onto Jupiter. On Dec. 7, 1995, the probe plummeted through Jupiter’s dense atmosphere, returning data along the way, until it succumbed to extreme pressures and temperatures. Meanwhile, Galileo entered orbit around Jupiter and far exceeded its 22-month primary mission, finally plunging into the giant planet on Sept. 21, 2003, 14 years after leaving Earth. During its 35 orbits around Jupiter, it studied not only the planet but made close observations of many of its moons, especially its four largest ones, Ganymede, Callisto, Europa, and Io.
Left: Galileo image of could formations on Jupiter. Right: Closeup image of terrain on Europa.
Of particular interest to many scientists, Galileo made 11 close encounters with icy Europa, coming as close as 125 miles, revealing incredible details about its surface. Based on Galileo data, scientists now believe a vast ocean lies beneath Europa’s icy crust, and heating from inside the moon may produce conditions favorable for supporting life. NASA’s Europa Clipper, launched on Oct. 14, 2024, hopes to expand on Galileo’s observations when it reaches Jupiter in April 2030.

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

“Right now, many different communities are all recognizing that we can partner to identify the best path forward,” Shuman said. “We have an opportunity to use everyone’s strengths and unique perspectives. It can be a devastating thing for a community and an ecosystem when a fire happens. Everyone is interested in using all this collective knowledge to do more, together.”
