NASA and its international partners are sending scientific investigations to the International Space Station on Northrop Grumman’s 21st commercial resupply services mission. Flying aboard the company’s Cygnus spacecraft are tests of water recovery technology and a process to produce stem cells in microgravity, studies of the effects of spaceflight on microorganism DNA and liver tissue growth, and live science demonstrations for students. The mission is scheduled to launch from Cape Canaveral Space Force Station in Florida by early August.

Testing materials for packed systems
Packed bed reactors are systems that use materials such as pellets or beads “packed” inside a structure to increase contact between different phases of fluids, such as liquid and gas. These reactors are used for various applications including water recovery, thermal management, and fuel cells. Scientists previously tested the performance in space of glass beads, Teflon beads, a platinum catalyst, and other packing materials. Packed Bed Reactor Experiment: Water Recovery Series evaluates gravity’s effects on eight additional test articles.
Results could help optimize the design and operation of packed bed reactors for water filtration and other systems in microgravity and on the Moon and Mars. Insights from the investigation also could lead to improvements in this technology for applications on Earth such as water purification and heating and cooling systems.

STEMonstrations Screaming Balloon uses a balloon, a penny, and a hexagonal nut (the kind used to secure a bolt) for a NASA STEMonstration performed and recorded by astronauts on the space station. The penny and the nut are whirled separately inside an inflated balloon to compare the sounds they make. Each STEMonstration illustrates a different scientific concept, such as centripetal force, and includes resources to help teachers further explore the topics with their students.

In-Space Expansion of Hematopoietic Stem Cells for Clinical Application (InSPA-StemCellEX-H1) continues testing a technology to produce human hematopoietic stem cells (HSCs) in space. HSCs give rise to blood and immune cells and are used in therapies for patients with certain blood diseases, autoimmune disorders, and cancers.
The investigation uses a system called BioServe In-space Cell Expansion Platform, or BICEP, which is designed to expand HSCs three hundredfold without the need to change or add new growth media, according to Louis Stodieck, principal investigator at the University of Colorado Boulder. “BICEP affords a streamlined operation to harvest and cryopreserve cells for return to Earth and delivery to a designated medical provider and patient,” said Stodieck.
Someone in the United States is diagnosed with a blood cancer such as leukemia about every three minutes. Treating these patients with transplanted stem cells requires a donor-recipient match and long-term repopulation of transplanted stem cells. This investigation demonstrates whether expanding stem cells in microgravity could generate far more continuously renewing stem cells.
“Our work eventually could lead to large-scale production facilities, with donor cells launched into orbit and cellular therapies returned to Earth,” said Stodieck.
NASA astronaut Frank Rubio works on the first test of methods for expanding stem cells in space, StemCellEX-H Pathfinder. The InSPA-StemCellEX-H1 investigation continues this work.NASA DNA repair in space
Rotifer-B2, an ESA (European Space Agency) investigation, explores how spaceflight affects DNA repair mechanisms in a microscopic bdelloid rotifer, Adineta vaga. These tiny but complex organisms are known for their ability to withstand harsh conditions, including radiation doses 100 times higher than human cells can survive. The organisms are dried, exposed to high radiation levels on Earth, and rehydrated and cultured in an incubator on the station.
“Previous research indicates that rotifers repair their DNA in space with the same efficiency as on Earth, but that research provided only genetic data,” said Boris Hespeels, co-investigator, of Belgium’s Laboratory of Evolutionary Genetics and Ecology. “This experiment will provide the first visual proof of survival and reproduction during spaceflight,” said Hespeels
Results could provide insights into how spaceflight affects the rotifer’s ability to repair sections of damaged DNA in a microgravity environment, and could improve the general understanding of DNA damage and repair mechanisms for applications on Earth.

Maturation of Vascularized Liver Tissue Construct studies the development in space of bioprinted liver tissue constructs that contain blood vessels. Constructs are tissue samples grown outside the body using bioengineering techniques. Scientists expect the microgravity environment to allow improved cellular distribution throughout tissue constructs.
“We are especially keen on accelerating the development of vascular networks,” said James Yoo, principal investigator, at the Wake Forest Institute of Regenerative Medicine. “The experimental data from microgravity will provide valuable insights that could enhance the biomanufacturing of vascularized tissues to serve as building blocks to engineer functional organs for transplantation.”

This mission also delivers plants for the APEX-09 investigation, which examines plant responses to stressful environments and could inform the design of bio-regenerative support systems on future space missions.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
By Wayne Smith
Investigators at NASA’s Marshall Space Flight Center in Huntsville, Alabama, will use observations from a recently-launched sounding rocket mission to provide a clearer image of how and why the Sun’s corona grows so much hotter than the visible surface of Earth’s parent star. The MaGIXS-2 mission – short for the second flight of the Marshall Grazing Incidence X-ray Spectrometer – launched from White Sands Missile Range in New Mexico on Tuesday, July 16.
NASA’s MaGIXS-2 sounding rocket mission successfully launched from White Sands Missile Range in New Mexico on July 16. United States Navy The mission’s goal is to determine the heating mechanisms in active regions on the Sun by making critical observations using X-ray spectroscopy.
The Sun’s surface temperature is around 10,000 degrees Fahrenheit – but the corona routinely measures more than 1.8 million degrees, with active regions measuring up to 5 million degrees.
Amy Winebarger, Marshall heliophysicist and principal investigator for the MaGIXS missions, said studying the X-rays from the Sun sheds light on what’s happening in the solar atmosphere – which, in turn, directly impacts Earth and the entire solar system.
X-ray spectroscopy provides unique capabilities for answering fundamental questions in solar physics and for potentially predicting the onset of energetic eruptions on the Sun like solar flares or coronal mass ejections. These violent outbursts can interfere with communications satellites and electronic systems, even causing physical drag on satellites as Earth’s atmosphere expands to absorb the added solar energy.
“Learning more about these solar events and being able to predict them are the kind of things we need to do to better live in this solar system with our Sun,” Winebarger said.
The NASA team retrieved the payload immediately after the flight and has begun processing datasets.
“We have these active regions on the Sun, and these areas are very hot, much hotter than even the rest of the corona,” said Patrick Champey, deputy principal investigator at Marshall for the mission. “There’s been a big question – how are these regions heated? We previously determined it could relate to how often energy is released. The X-rays are particularly sensitive to this frequency number, and so we built an instrument to look at the X-ray spectra and disentangle the data.”
The MaGIXS-2 sounding rocket team stand on the launchpad in White Sands, New Mexico prior to launch on July 16, 2024. United States Navy Following a successful July 2021 launch of the first MaGIXS mission, Marshall and its partners refined instrumentation for MaGIXS-2 to provide a broader view for observing the Sun’s X-rays. Marshall engineers developed and fabricated the telescope and spectrometer mirrors, and the camera. The integrated instrument was exhaustively tested in Marshall’s state-of-the-art X-ray & Cryogenic Facility. For MaGIXS-2, the team refined the same mirrors used on the first flight, with a much larger aperture and completed the testing at Marshall’s Stray Light Test Facility.
A Marshall project from inception, technology developments for MaGIXS include the low-noise CCD camera, high-resolution X-ray optics, calibration methods, and more.
Winebarger and Champey said MaGIXS many of the team members started their NASA careers with the project, learning to take on lead roles and benefitting from mentorship.
“I think that’s probably the most critical thing, aside from the technology, for being successful,” Winebarger said. “It’s very rare that you get from concept to flight in a few years. A young engineer can go all the way to flight, come to White Sands to watch it launch, and retrieve it.”
NASA routinely uses sounding rockets for brief, focused science missions. They’re often smaller, more affordable, and faster to design and build than large-scale satellite missions, Winebarger said. Sounding rockets carry scientific instruments into space along a parabolic trajectory. Their overall time in space is brief, typically five minutes, and at lower vehicle speeds for a well-placed scientific experiment.
The MaGIXS mission was developed at Marshall in partnership with the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts. The Sounding Rockets Program Office, located at NASA Goddard Space Flight Center’s Wallops Flight Facility, provides suborbital launch vehicles, payload development, and field operations support to NASA and other government agencies.

ESA’s (European Space Agency) Ariane 6 rocket launches NASA’s CURIE CubeSat from Europe’s Spacesport, the Guiana Space Center in Kourou, French Guiana on Tuesday, July 9, 2024. Photo credit: ESA/S. Corvaja NASA launched CURIE (CubeSat Radio Interferometry Experiment) as a rideshare payload on the inaugural flight of ESA’s (European Space Agency) Ariane 6 rocket, which launched at 4 p.m. GFT on July 9 from Europe’s Spaceport, the Guiana Space Center in Kourou, in French Guiana.
Designed by a team from the University of California, Berkeley, CURIE will use radio interferometry to study the primary drivers of space weather.
CubeSats are built using standardized units, with one unit, or 1U, measuring about 10 centimeters in length, width, and height. The two-satellite CURIE mission launched as a 6U before separating into two separate spacecraft, each a 3U. The spacecraft will provide two separate vantage points to measure the same radio waves coming from the Sun and other sources in the sky.
NASA’s CubeSat Launch Initiative selected CURIE in 2020 during the initiative’s 11th round of applications. NASA’s Launch Services Program, in collaboration with ESA, designated CURIE as one of eleven payloads supplied by space agencies, commercial companies, and universities for the first flight of ESA’s Ariane 6 rocket.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
An aerial view of Palmyra Atoll, where animal tracking data now being studied by NASA’s Internet of Animals project was collected using wildlife tags by partners at The Nature Conservancy, the U.S. Geological Survey, the National Oceanic and Atmospheric Administration, and several universities.The Nature Conservancy/Kydd Pollock Anchoring the boat in a sandbar, research scientist Morgan Gilmour steps into the shallows and is immediately surrounded by sharks. The warm waters around the tropical island act as a reef shark nursery, and these baby biters are curious about the newcomer. They zoom close and veer away at the last minute, as Gilmour slowly makes her way toward the kaleidoscope of green sprouting from the island ahead.
Gilmour, a scientist at NASA’s Ames Research Center in California’s Silicon Valley, conducts marine ecology and conservation studies using data collected by the U.S. Geological Survey (USGS) from animals equipped with wildlife tags. Palmyra Atoll, a United States marine protected area, provides the perfect venue for this work.
A juvenile blacktip reef shark swims toward researchers in the shallow waters around Palmyra Atoll.The Nature Conservancy/Kydd Pollock A collection of roughly 50 small islands in the tropical heart of the Pacific Ocean, the atoll is bursting with life of all kinds, from the reef sharks and manta rays circling the shoreline to the coconut crabs climbing palm branches and the thousands of seabirds swooping overhead. By analyzing the movements of dolphins, tuna, and other creatures, Gilmour and her collaborators can help assess whether the boundaries of the marine protected area surrounding the atoll actually protect the species they intend to, or if its limits need to shift.
Launched in 2020 by The Nature Conservancy and its partners – USGS, NOAA (National Oceanic and Atmospheric Administration), and several universities – the project team deployed wildlife tags at Palmyra in 2022, when Gilmour was a scientist with USGS.
Now with NASA, she is leveraging the data for a study under the agency’s Internet of Animals project. By combining information transmitted from wildlife tags with information about the planet collected by satellites – such as NASA’s Aqua, NOAA’s GOES (Geostationary Operational Environmental Satellite) satellites, and the U.S.-European Jason-3 – scientists can work with partners to draw conclusions that inform ecological management.
The Palmyra Atoll is a haven for biodiversity, boasting thriving coral reef systems, shallow waters that act as a shark nursery, and rich vegetation for various land animals and seabirds. In the Landsat image above, a small white square marks the research station, where scientists from all over the world come to study the many species that call the atoll home.NASA/Earth Observatory Team “Internet of Animals is more than just an individual collection of movements or individual studies; it’s a way to understand the Earth at large,” said Ryan Pavlick, then Internet of Animals project scientist at NASA’s Jet Propulsion Laboratory in Southern California, during the project’s kickoff event.
The Internet of Animals at Palmyra
“Our work at Palmyra was remarkably comprehensive,” said Gilmour. “We tracked the movements of eight species at once, plus their environmental conditions, and we integrated climate projections to understand how their habitat may change. Where studies may typically track two or three types of birds, we added fish and marine mammals, plus air and water column data, for a 3D picture of the marine protected area.”
Tagged Yellowfin Tuna, Grey Reef Sharks, and Great Frigatebirds move in and out of a marine protected area (blue square), which surrounds the Palmyra Atoll (blue circle) in the tropical heart of the Pacific. These species are three of many that rely on the atoll and its surrounding reefs for food and for nesting.NASA/Lauren Dauphin Now, the NASA team has put that data into a species distribution model, which combines the wildlife tracking information with environmental data from satellites, including sea surface temperature, chlorophyll concentration, and ocean current speed. The model can help researchers understand how animal populations use their habitats and how that might shift as the climate changes.
Preliminary results from Internet of Animals team show that the animals tracked are moving beyond the confines of the Palmyra marine protected area. The model identified suitable habitats both in and around the protected zone – now and under predicted climate change scenarios – other researchers and decisionmakers can utilize that knowledge to inform marine policy and conservation.
Research scientist Morgan Gilmour checks on a young great frigatebird in its nest. The marine protected area around Palmyra Atoll protects these birds’ breeding grounds.UC Santa Barbara/Devyn Orr Following a 2023 presidential memorandum, NOAA began studying and gathering input on whether to expand the protected areas around Palmyra and other parts of the Pacific Remote Islands Marine National Monument. Analysis from NASA’s Internet of Animals could inform that and similar decisions, such as whether to create protected “corridors” in the ocean to allow for seasonal migrations of wildlife. The findings and models from the team’s habitat analysis at Palmyra also could help inform conservation at similar latitudes across the planet.
Beyond the Sea: Other Internet of Animals Studies
Research at Palmyra Atoll is just one example of work by Internet of Animals scientists.
Claire Teitelbaum, a researcher with the Bay Area Environmental Research Institute based at NASA Ames, studies avian flu in wild waterfowl, investigating how their movement may contribute to transmission of the virus to poultry and other domestic livestock.
Teams at Ames and JPL are also working with USGS to create next-generation wildlife tags and sensors. Low-power radar tags in development at JPL would be lightweight enough to track small birds. Ames researchers plan to develop long-range radio tags capable of maximizing coverage and transmission of data from high-flying birds. This could help researchers take measurements in hard-to-reach layers of the atmosphere.
With the technology brought together by the Internet of Animals, even wildlife can take an active role in the study of Earth’s interacting systems, helping human experts learn more about our planet and how best to confront the challenges facing the natural world.

The Internet of Animals project is funded by NASA and managed at NASA’s Jet Propulsion Laboratory in Southern California. The team at NASA’s Ames Research Center in California’s Silicon Valley is part of the NASA Earth Exchange, a Big Data initiative providing unique insights into Earth’s systems using the agency’s supercomputers at the center. Partners on the project include the U.S. Geological Survey, The Nature Conservancy, the National Oceanic and Atmospheric Administration, the Yale Center for Biodiversity and Global Change, Stanford University, University of Hawaii, University of California Santa Barbara, San Jose State University, University of Washington, and the Max Planck Institute for Animal Behavior.
