3 Min Read NASA, Partners to Conduct Space Station Research During Expedition 73
NASA NASA astronauts are gearing up for a scientific mission aboard the International Space Station. Expedition 73 NASA astronauts Nichole Ayers and Anne McClain, JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi, and Roscosmos cosmonaut Kirill Peskov will launch in March as part of the agency’s SpaceX Crew-10 mission. NASA astronaut Jonny Kim will join the crew when he launches aboard the Roscosmos Soyuz MS-27 spacecraft in April alongside Roscosmos cosmonauts Sergey Ryzhikov and Alexey Zubritsky.
Read more about some of the microgravity research planned by NASA and its partners:
Subjects for human research
NASA Astronauts often serve as test subjects, submitting blood and other samples for research. NASA astronaut Anne McClain is pictured submitting a sample on a previous mission with assistance from CSA (Canadian Space Agency) astronaut David Saint-Jacques. McClain will participate in NASA’s Complement of Integrated Protocols for Human Exploration Research investigation, or CIPHER, a suite of integrated studies on physiological and psychological changes seen in space. Results could provide valuable insights for future deep space missions.
Testing lunar navigation
NASA When Expedition 73 astronauts engage with students worldwide via the ISS Ham Radio program, researchers will use the ham radio hardware to test software for the Navigation and Communication Testbed (NAVCOM) that could help shape future lunar navigation. Researchers from the investigation recently launched a related study to the Moon aboard Firefly’s Blue Ghost to help bridge existing Earth navigation with emerging lunar-specific solutions.
Advancing fire safety
NASA Expedition 73 is scheduled to conduct a Material Ignition and Suppression Test (SoFIE-MIST), testing material flammability in microgravity. This research could improve fire safety on future missions, contributing to models used to select materials for space facilities and helping to determine the best ways to extinguish fires in space.
Keeping blood flowing
Angelo Taibi/ASI Expedition 73 crew members will participate in Drain Brain 2.0, which examines how blood flows from the brain to the heart in microgravity using this plethysmograph, a device that can record the volume of blood drainage from the skull. Results could identify which processes in the body compensate for the lack of gravity, helping to ensure proper blood flow for astronauts on future missions and people with cardiovascular issues on Earth.
The International Space Station is a convergence of science, technology, and human innovation that enables research not possible on Earth. For more than 24 years, NASA has supported a continuous U.S. human presence aboard the orbiting laboratory, through which astronauts have learned to live and work in space for extended periods of time. The space station is a springboard for developing a low Earth economy and NASA’s next great leaps in exploration, including missions to the Moon under Artemis and, ultimately, human exploration of Mars.

NASA/JPL-Caltech/UCLA/MPS/DLR/IDA NASA’s Dawn spacecraft took this image of Ceres’ south polar region on May 17, 2017. Launched on Sept. 27, 2007, Dawn was NASA’s first truly interplanetary spaceship. The mission featured extended stays at two extraterrestrial bodies: giant asteroid Vesta and dwarf planet Ceres, both in the debris-strewn main asteroid belt between Mars and Jupiter.
The spacecraft’s name was meant to present a simple view of the mission’s purpose: to provide information on the dawn of the solar system. The three principal scientific drivers for the mission were to capture the earliest moments in the origin of the solar system, determine the nature of the building blocks from which the terrestrial planets formed, and contrast the formation and evolution of two small planets that followed very different evolutionary paths.
Dawn completed the first order exploration of the inner solar system, addressed NASA’s goal of understanding the origin and evolution of the solar system, and complemented investigations of Mercury, Earth, and Mars. Dawn’s mission ended on Nov. 1, 2018, after two extended missions.
Follow Dawn’s journey from Earth to deep space through the words of mission director and chief engineer, Dr. Marc Rayman.

NASA, ESA, CSA, M. Meyer (University of Michigan), A. Pagan (STScI) The Flame Nebula, located about 1,400 light-years away from Earth, is a hotbed of star formation less than 1 million years old. Within the Flame Nebula, there are objects so small that their cores will never be able to fuse hydrogen like full-fledged stars—brown dwarfs.
Brown dwarfs, often called “failed stars,” over time become very dim and much cooler than stars. These factors make observing brown dwarfs with most telescopes difficult, if not impossible, even at cosmically short distances from the Sun. When they are very young, however, they are still relatively warmer and brighter and therefore easier to observe despite the obscuring, dense dust and gas that comprises the Flame Nebula in this case.
NASA’s James Webb Space Telescope can pierce this dense, dusty region and see the faint infrared glow from young brown dwarfs. A team of astronomers used this capability to explore the lowest mass limit of brown dwarfs within the Flame Nebula. The result, they found, were free-floating objects roughly two to three times the mass of Jupiter, although they were sensitive down to 0.5 times the mass of Jupiter.
“The goal of this project was to explore the fundamental low-mass limit of the star and brown dwarf formation process. With Webb, we’re able to probe the faintest and lowest mass objects,” said lead study author Matthew De Furio of the University of Texas at Austin.
Image A: Flame Nebula: Hubble and Webb Observations
This collage of images from the Flame Nebula shows a near-infrared light view from NASA’s Hubble Space Telescope on the left, while the two insets at the right show the near-infrared view taken by NASA’s James Webb Space Telescope. Much of the dark, dense gas and dust, as well as the surrounding white clouds within the Hubble image, have been cleared in the Webb images, giving us a view into a more translucent cloud pierced by the infrared-producing objects within that are young stars and brown dwarfs. Astronomers used Webb to take a census of the lowest-mass objects within this star-forming region.
The Hubble image on the left represents light at wavelengths of 1.05 microns (filter F105W) as blue, 1.3 microns (F130N) as green, and 1.39 microns (F129M) as red. The two Webb images on the right represent light at wavelengths of 1.15 microns and 1.4 microns (filters F115W and F140M) as blue, 1.82 microns (F182M) as green, 3.6 microns (F360M) as orange, and 4.3 microns (F430M) as red. NASA, ESA, CSA, M. Meyer (University of Michigan), A. Pagan (STScI) Smaller Fragments
The low-mass limit the team sought is set by a process called fragmentation. In this process large molecular clouds, from which both stars and brown dwarfs are born, break apart into smaller and smaller units, or fragments.
Fragmentation is highly dependent on several factors with the balance between temperature, thermal pressure, and gravity being among the most important. More specifically, as fragments contract under the force of gravity, their cores heat up. If a core is massive enough, it will begin to fuse hydrogen. The outward pressure created by that fusion counteracts gravity, stopping collapse and stabilizing the object (then known as a star). However, fragments whose cores are not compact and hot enough to burn hydrogen continue to contract as long as they radiate away their internal heat.
“The cooling of these clouds is important because if you have enough internal energy, it will fight that gravity,” says Michael Meyer of the University of Michigan. “If the clouds cool efficiently, they collapse and break apart.”
Fragmentation stops when a fragment becomes opaque enough to reabsorb its own radiation, thereby stopping the cooling and preventing further collapse. Theories placed the lower limit of these fragments anywhere between one and ten Jupiter masses. This study significantly shrinks that range as Webb’s census counted up fragments of different masses within the nebula.
“As found in many previous studies, as you go to lower masses, you actually get more objects up to about ten times the mass of Jupiter. In our study with the James Webb Space Telescope, we are sensitive down to 0.5 times the mass of Jupiter, and we are finding significantly fewer and fewer things as you go below ten times the mass of Jupiter,” De Furio explained. “We find fewer five-Jupiter-mass objects than ten-Jupiter-mass objects, and we find way fewer three-Jupiter-mass objects than five-Jupiter-mass objects. We don’t really find any objects below two or three Jupiter masses, and we expect to see them if they are there, so we are hypothesizing that this could be the limit itself.”
Meyer added, “Webb, for the first time, has been able to probe up to and beyond that limit. If that limit is real, there really shouldn’t be any one-Jupiter-mass objects free-floating out in our Milky Way galaxy, unless they were formed as planets and then ejected out of a planetary system.”
Image B: Low Mass Objects within the Flame Nebula in Infrared Light
This near-infrared image of a portion of the Flame Nebula from NASA’s James Webb Space Telescope highlights three low-mass objects, seen in the insets to the right. These objects, which are much colder than protostars, require the sensitivity of Webb’s instruments to detect them. These objects were studied as part of an effort to explore the lowest mass limit of brown dwarfs within the Flame Nebula.
The Webb images represent light at wavelengths of 1.15 microns and 1.4 microns (filters F115W and F140M) as blue, 1.82 microns (F182M) as green, 3.6 microns (F360M) as orange, and 4.3 microns (F430M) as red. NASA, ESA, CSA, STScI, M. Meyer (University of Michigan) Building on Hubble’s Legacy
Brown dwarfs, given the difficulty of finding them, have a wealth of information to provide, particularly in star formation and planetary research given their similarities to both stars and planets. NASA’s Hubble Space Telescope has been on the hunt for these brown dwarfs for decades.
Even though Hubble can’t observe the brown dwarfs in the Flame Nebula to as low a mass as Webb can, it was crucial in identifying candidates for further study. This study is an example of how Webb took the baton—decades of Hubble data from the Orion Molecular Cloud Complex—and enabled in-depth research.
“It’s really difficult to do this work, looking at brown dwarfs down to even ten Jupiter masses, from the ground, especially in regions like this. And having existing Hubble data over the last 30 years or so allowed us to know that this is a really useful star-forming region to target. We needed to have Webb to be able to study this particular science topic,” said De Furio.
“It’s a quantum leap in our capabilities between understanding what was going on from Hubble. Webb is really opening an entirely new realm of possibilities, understanding these objects,” explained astronomer Massimo Robberto of the Space Telescope Science Institute.
This team is continuing to study the Flame Nebula, using Webb’s spectroscopic tools to further characterize the different objects within its dusty cocoon.
“There’s a big overlap between the things that could be planets and the things that are very, very low mass brown dwarfs,” Meyer stated. “And that’s our job in the next five years: to figure out which is which and why.”
These results are accepted for publication in The Astrophysical Journal Letters.
Image C (Animated): Flame Nebula (Hubble and Webb Comparison)
This animated image alternates between a Hubble Space Telescope and a James Webb Space Telescope observation of the Flame Nebula, a nearby star-forming nebula less than 1 million years old. In this comparison, three low-mass objects are highlighted. In Hubble’s observation, the low-mass objects are hidden by the region’s dense dust and gas. However, the objects are brought out in the Webb observation due to Webb’s sensitivity to faint infrared light. NASA, ESA, CSA, Alyssa Pagan (STScI) The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

Will you design the zero gravity indicator (ZGI) that accompanies the Artemis II mission around the Moon? If your design is one of the most compelling and resonates with the global community and the Artemis II astronauts, your design might fly into space aboard the Orion spacecraft and you could win US$1225. Zero gravity indicators are small items carried aboard spacecraft that provide a visual indicator for when a spacecraft has reached the weightlessness of microgravity. A plush Snoopy doll was the ZGI for the Artemis I mission. For that uncrewed mission, Snoopy floated around, tethered inside the vehicle to indicate when the Orion spacecraft had reached space. For this Challenge, we’re asking creatives from all over the world to design a new ZGI to be fabricated by NASA’s Thermal Blanket Lab and launched into space aboard the Artemis II mission.
Award: $23,275 in total prizes

Challenges to measuring space-induced brain changes
CSA (Canadian Space Agency) astronaut David Saint-Jacques undergoes an MRI for Wayfinding. CSA Researchers found that an upward shift in the brain during spaceflight makes it hard to distinguish different types of tissue, causing errors in determining changes in brain volume. Previous studies have interpreted these changes as evidence of adaptation to space. This finding suggests that unique methods are needed to analyze astronaut brain structure.
Wayfinding, a CSA (Canadian Space Agency) investigation, looked at how the brain adapts to space and readapts after return to normal gravity using a variety of assessments, including neuroimaging. The researchers propose that previous data could be reanalyzed based on the errors identified by this paper.
Catching micrometeoroids
JAXA’s (Japan Aerospace Exploration Agency) Tanpopo panels were mounted on the Exposed Experiment Handrail Attachment Mechanism (ExHAM) at top center of this image. JAXA/Takuya Onishi An impact track made by a micrometeoroid on a panel outside the International Space Station contained iron and orthopyroxene crystals. This finding, along with previous studies, suggests that micrometeoroids containing these elements are abundant in low Earth orbit and more measurements are needed to determine their origins and potential for carrying life.
At least 90% of meteoroids at one astronomical unit or AU (93 million miles or the distance between Earth and the Sun) do not reach Earth’s surface, so investigating those in low Earth orbit is key to understanding their nature. The JAXA (Japan Aerospace Exploration Agency) Tanpopo experiment placed blocks of a special gel outside the station to capture solid microparticles to test the theory that they could transport life among celestial bodies. Most meteoroids at one AU may have originated from Jupiter family comets.
