NASA’s LEO Microgravity Strategy effort aims to develop and document an objectives-based approach toward the next generation of human presence in low Earth orbit to advance microgravity science, technology, and exploration.NASA/Joel Kowsky As part of NASA’s effort to advance microgravity science, technology, and exploration in low Earth orbit (LEO), the agency conducted two stakeholder workshops in London and Washington to solicit feedback from the international community, including NASA’s international partners, American industry, and academia on Sept. 6 and Sept. 13, respectively.
The agency released a draft set of 42 objectives in late August, seeking input from U.S. industry, academia, international communities, NASA employees, and others to ensure its framework for the next generation of human presence in low Earth orbit, set to be finalized this winter, includes ideas and contributions from a range of stakeholders. The objectives span six categories: science, exploration-enabling research and technology development, commercial low Earth orbit infrastructure, operations, international cooperation, and workforce and engagement.
“As we chart the future of human exploration, it’s vital that we harness the insights and expertise of our diverse stakeholders,” said NASA Deputy Administrator Pam Melroy. “These workshops provide an invaluable platform for stakeholders to share their insights, helping us create a strategy that reflects our shared ambitions for the future of space exploration.”
Consultation is a fundamental aspect of NASA’s LEO Microgravity Strategy, emphasizing the importance of collaboration and the integration of diverse perspectives in advancing scientific research and technology development in low Earth orbit. By actively engaging with stakeholders –including scientists, industry partners, and educational institutions –NASA aims to gather valuable insights and align its objectives with the broader goals of the space community.
“Engaging with a wide array of voices allows us to tap into innovative ideas that will enhance our missions,” stated Robyn Gatens, director of the International Space Station and acting director of Commercial Spaceflight. “This collaborative approach not only strengthens our current initiatives but also lays the groundwork for future advancements in space exploration.”

“From the very beginning, NASA’s flagship human spaceflight programs have built upon each other, expanding our knowledge and experience of humans living and working in space,” said NASA Deputy Administrator Pam Melroy. “As commercial industry is constructing new human-enabled platforms for low Earth orbit, NASA must answer the question: what should our goals and objectives be to advance our future science and exploration missions?”
NASA published draft high-level goals and objectives outlining 42 key points in six main areas: science, exploration-enabling research and technology development, commercial low Earth orbit infrastructure, operations, international cooperation, and workforce and engagement.
“Feedback is essential for shaping our long-term microgravity research and development activities,” said Ken Bowersox, associate administrator, Space Operations Mission Directorate at NASA Headquarters in Washington. “We are committed to refining our objectives with input from both within NASA and external partners, ensuring alignment with industry and international goals. After reviewing feedback, we will finalize our strategy later this year.”
The agency will conduct two invite-only workshops in September to discuss feedback on the draft goals and objectives. The first workshop is with international partners, and the second will engage U.S. industry and academic representatives.
NASA employees also are invited to provide input through internal agency channels. This approach reflects NASA’s commitment to harnessing diverse perspectives to navigate the rapidly evolving low Earth orbit environment.
“Organizations are increasingly recognizing the transformative benefits of space, with both governments and commercial activities leveraging the International Space Station as a testbed,” said Robyn Gatens, International Space Station director and acting director of commercial spaceflight at NASA Headquarters. “By developing a comprehensive strategy, NASA is looking to the next chapter of U.S. human space exploration to help shape the agency’s future in microgravity for the benefit of all.”
Stakeholders may submit comments by close of business on Friday, Sept. 27 to:

On July 8, 1994, space shuttle Columbia took to the skies on its 17th trip into space, on the second International Microgravity Laboratory (IML-2) mission. Six space agencies sponsored 82 life and microgravity science experiments. The seven-person crew consisted of Commander Robert D. Cabana, Pilot James D. Halsell, Payload Commander Richard J. Hieb, Mission Specialists Carl E. Walz, Leroy Chiao, and Donald A. Thomas, and Payload Specialist Chiaki Mukai representing the National Space Development Agency (NASDA) of Japan, now the Japan Aerospace Exploration Agency. Jean-Jacques H. Favier of the French space agency CNES served as a backup payload specialist. During their then-record setting 15-day shuttle flight, the international team of astronauts successfully completed the science program. They returned to earth on July 23.

Halsell, Chiaki Mukai of Japan, and Carl E. Walz. Right: The payload patch for the International Microgravity Laboratory-2.
In August 1973, NASA and the European Space Research Organization, reorganized as the European Space Agency (ESA) in 1975, agreed to build a reusable laboratory called Spacelab to fly in the space shuttle’s cargo bay. As part of the agreement, ESA built two pressurized modules in addition to other supporting hardware. First flying on STS-9 in 1983, the 18-foot-long pressurized Spacelab module made its 10th flight on STS-65. In September 1992 NASA named Hieb as the IML-2 payload commander and Mukai and Favier as prime and backup payload specialists, respectively, adding Chiao and Thomas as mission specialists in October 1992, finally designating Cabana, Halsell, and Walz as the orbiter crew in August 1993. For Cabana and Hieb, both selected as astronauts in 1985, STS-65 marked their third spaceflight. NASA selected Halsell, Walz, Chiao, and Thomas in 1990, in the class nicknamed The Hairballs. Walz would make his second flight, with the other three making their first. NASDA selected Mukai in 1985 and she holds the distinction as the first Japanese woman in space. Chiao and Mukai as part of the STS-65 crew marked the first time that two Asians flew on the shuttle at the same time, and with Kazakh cosmonaut Talgat A. Musbayev aboard Mir, the first time that three people of Asian origins flew in space at the same time.

Columbia returned to NASA’s Kennedy Space Center (KSC) in Florida following its previous flight, STS-62, in March 1994. Technicians in KSC’s Orbiter Processing Facility (OPF) serviced the orbiter, removed the previous payload, and installed the Spacelab module in the payload bay. Following a successful leak check of the Spacelab module, rollover of Columbia from the OPF to the Vehicle Assembly Building (VAB) took place on June 8, where workers mated it with an external tank (ET) and two solid rocket boosters (SRBs). Following integrated testing, the stack rolled out to Launch Pad 39A seven days later. The crew participated in the Terminal Countdown Demonstration Test on June 22.
Liftoff of space shuttle Columbia on STS-65 carrying the second International Microgravity Laboratory.
On July 8, 1994, precisely on time, Columbia thundered off KSC’s Launch Pad 39A to begin the STS-65 mission. For the first time in shuttle history, a video camera recorded the liftoff from the orbiter’s flight deck, showing the vibrations during the first two minutes while the SRBs fired, smoothing out once the shuttle main engines took over. Mounted inside Columbia’s payload bay, the Spacelab 18-foot-long module provided a shirt-sleeve environment for the astronauts to conduct the scientific experiments. As during many Spacelab missions, the STS-65 crew carried out science operations 24-hours a day, divided into two teams – the red shift comprised Cabana, Halsell, Hieb, and Mukai, while Chiao, Thomas, and Walz made up the blue shift.

After reaching orbit, the crew opened the payload bay doors and deployed the shuttle’s radiators, and removed their bulky launch and entry suits, stowing them for the remainder of the flight. Shortly after, Hieb opened the hatch to the transfer tunnel and translated through it to enter the Spacelab module for the first time. He and Mukai activated the module and turned on the first experiments. For the next 14 days, the astronauts worked round the clock, with Cabana, Halsell, and Walz managing the shuttle’s systems while Hieb, Chiao, Thomas, and Mukai conducted the bulk of the research. The astronauts commemorated the 25th anniversary of the Apollo 11 launch on July 16 and the Moon landing four days later, recalling that their spacecraft and the Command Module shared the name Columbia.

At the end of 13 days, the astronauts finished the last of the experiments and deactivated the Spacelab module. Managers waved off the planned landing on July 22 due to cloudy weather at KSC. On July 23, the astronauts closed the hatch to the Spacelab module for the final time, closed Columbia’s payload bay doors, donned their launch and entry suits, and strapped themselves into their seats for entry and landing. Cabana piloted Columbia to a smooth landing on KSC’s Shuttle Landing Facility, completing 236 orbits around the Earth in 14 days, 17 hours, and 55 minutes, at the time the longest shuttle flight. Mukai set a then-record for the longest single flight by a woman. In October 1994, Columbia returned to its manufacturer, Rockwell International in Palmdale, California, for scheduled modification and refurbishment before its next mission, STS-73, in October 1995.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Despite some years with significant snowfalls, long-term drought conditions in the Great Basin region of Nevada, California, Arizona, and Utah, along with increasing water demands, have strained water reserves in the western U.S. As a result, inland bodies of water, including the Great Salt Lake pictured here, have shrunk dramatically, exposing lakebeds that may release toxic dust when dried.Dorothy Hall/University of Maryland Record snowfall in recent years has not been enough to offset long-term drying conditions and increasing groundwater demands in the U.S. Southwest, according to a new analysis of NASA satellite data.
Declining water levels in the Great Salt Lake and Lake Mead have been testaments to a megadrought afflicting western North America since 2000. But surface water only accounts for a fraction of the Great Basin watershed that covers most of Nevada and large portions of California, Utah, and Oregon. Far more of the region’s water is underground. That has historically made it difficult to track the impact of droughts on the overall water content of the Great Basin.
A new look at 20 years of data from the Gravity Recovery and Climate Experiment (GRACE) series of satellites shows that the decline in groundwater in the Great Basin far exceeds stark surface water losses. Over about the past two decades, the underground water supply in the basin has fallen by 16.5 cubic miles (68.7 cubic kilometers). That’s roughly two-thirds as much water as the entire state of California uses in a year and about six times the total volume of water that was left in Lake Mead, the nation’s largest reservoir, at the end of 2023.
While new maps show a seasonal rise in water each spring due to melting snow from higher elevations, University of Maryland earth scientist Dorothy Hall said occasional snowy winters are unlikely to stop the dramatic water level decline that’s been underway in the U.S. Southwest.
The finding came about as Hall and colleagues studied the contribution of annual snowmelt to Great Basin water levels. “In years like the 2022-23 winter, I expected that the record amount of snowfall would really help to replenish the groundwater supply,” Hall said. “But overall, the decline continued.” The research was published in March 2024 in the journal Geophysical Research Letters.
“A major reason for the decline is the upstream water diversion for agriculture and households,” Hall said. Populations in the states that rely on Great Basin water supplies have grown by 6% to 18% since 2010, according to the U.S. Census Bureau. “As the population increases, so does water use.”
Runoff, increased evaporation, and water needs of plants suffering hot, dry conditions in the region are amplifying the problem. “With the ongoing threat of drought,” Hall said, “farmers downstream often can’t get enough water.”
Gravity measurements from the GRACE series of satellites show that the decline in water levels in the Great Basin region from April 2002 to September 2023 has most severely affected portions of southern California (indicated in red).D.K. Hall et al./Geophysical Research Letters 2024 While measurements of the water table in the Great Basin — including the depths required to connect wells to depleted aquifers — have hinted at declining groundwater, data from the joint German DLR-NASA GRACE missions provide a clearer picture of the total loss of water supply in the region. The original GRACE satellites, which flew from March 2002 to October 2017, and the successor GRACE–Follow On (GRACE–FO) satellites, which launched in May 2018 and are still active, track changes in Earth’s gravity due primarily to shifting water mass.
GRACE-based maps of fluctuating water levels have improved recently as the team has learned to parse more and finer details from the dataset. “Improved spatial resolution helped in this study to distinguish the location of the mass trends in the Western U.S. roughly ten times better than prior analyses,” said Bryant Loomis, who leads GRACE data analysis at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
The diminishing water supplies of the U.S. Southwest could have consequences for both humans and wildlife, Hall said. In addition to affecting municipal water supplies and limiting agricultural irrigation, “It exposes the lake beds, which often harbor toxic minerals from agricultural runoff, waste, and anything else that ends up in the lakes.”
In Utah, a century of industrial chemicals accumulated in the Great Salt Lake, along with airborne pollutants from present-day mining and oil refinement, have settled in the water. The result is a hazardous muck that is uncovered and dried as the lake shrinks. Dust blown from dry lake beds, in turn, exacerbates air pollution in the region. Meanwhile, shrinking lakes are putting a strain on bird populations that rely on the lakes as stopovers during migration.
According to the new findings, Hall said, “The ultimate solution will have to include wiser water management.”

A visitor operates the new exhibit at the NASA Glenn Visitor Center that features motion sensors, touch screens, and videos.Credit: NASA/Christopher Hartenstine The Fluids and Combustion Facility, or FCF, on the International Space Station was designed and built at NASA’s Glenn Research Center in Cleveland and has been supporting microgravity research for over a decade. A new exhibit at the NASA Glenn Visitor Center, located in the Great Lakes Science Center, brings that research down to Earth in a fun and user-friendly way.
The exhibit replicates the FCF, which houses two research facilities—the Combustion Integrated Rack, or CIR, and the Fluids Integrated Rack, or FIR. Both were developed at NASA Glenn with prime contractor ZIN Technologies and are operated remotely from Glenn’s ISS Payloads Operation Center. The FCF supports physical and biological experiments to advance technology development while bringing many benefits back here to Earth.
“Gravity on Earth affects everything from flames to fluids,” said Kelly Bailey, Physical Sciences Research Program manager at NASA Glenn. “Because gravity can mask other forces in play on Earth, it’s important to conduct science on the space station and remove gravity as a variable.”
A new interactive exhibit at the NASA Glenn Visitor Center replicates the Fluids and Combustion Facility on the International Space Station, enabling users to see how microgravity experiments operate.Credit: NASA/Christopher Hartenstine Bailey worked with a design team to create an interactive educational tool for the new exhibit that features motion sensors, touch screens, and videos. Colorful graphic characters depicting fire and water guide users through many Glenn-developed experiments successfully operated within the FCF. Each rack on the exhibit contains an introduction along with two to three experiments for visitors to learn about.
The CIR rack focuses on combustion (fire) research. Users can pick from Flames in Space (Flame Extinguishment Experiment) and Cool Flames (Advanced Combustion via Microgravity Experiments) modules.
The FIR focuses on fluids research and highlights the Light Microscopy Module, or LMM, a light imaging microscope facility that provides researchers with powerful diagnostic hardware and software. Within the FIR rack, users receive an introduction to LMM and can choose from Plants in Space (Advanced Plant Experiment), Bubbles in Space (Constrained Vapor Bubble), and Particles in Space (Advanced Colloids Experiments) modules.
“People may not realize the volume of science performed daily in space, and the importance of that research truly impacts their lives,” Bailey said. “This interactive exhibit offers an immersive experience into the world of microgravity science research and the important work happening at NASA.”
