Science in Space: February 2025

February was first proclaimed as American Heart Month in 1964. Since then, its 28 (or 29) days have served as an opportunity to encourage people to focus on their cardiovascular health.

The International Space Station serves as a platform for a variety of ongoing research on human health, including how different body systems adapt to weightlessness. This research includes assessing cardiovascular health in astronauts during and after spaceflight and other studies using models of the cardiovascular system, such as tissue cultures. The goal of this work is to help promote heart health for humans in space and everyone on Earth. For this Heart Month, here is a look at some of this spaceflight research

Building a better heart model

Microgravity exposure is known to cause changes in cardiovascular function. Engineered Heart Tissues assessed these changes using 3D cultured cardiac tissues that model the behavior of actual heart tissues better than traditional cell cultures. When exposed to weightlessness, these “heart-on-a-chip” cells behaved in a manner similar to aging on Earth. This finding suggests that these engineered tissues can be used to investigate the effects of space radiation and long-duration spaceflight on cardiac function. Engineered tissues also could support development of measures to help protect crew members during a mission to Mars. Advanced 3D culture methodology may inform development of strategies to prevent and treat cardiac diseases on Earth as well.

Private astronaut heart health

NASA

For decades, human research in space has focused on professional and government-agency astronauts, but commercial spaceflight opportunities now allow more people to participate in microgravity research. Cardioprotection Ax-1 analyzed cardiovascular and general health in private astronauts on the 17-day Axiom-1 mission.

The study found that 14 health biomarkers related to cardiac, liver, and kidney health remained within normal ranges during the mission, suggesting that spaceflight did not significantly affect the health of the astronaut subjects. This study paves the way for monitoring and studying the effects of spaceflight on private astronauts and developing health management plans for commercial space providers.

Better measurements for better health

Vascular Echo, an investigation from CSA (Canadian Space Agency), examined blood vessels and the heart using a variety of tools, including ultrasound. A published study suggests that 3D imaging technology might better measure cardiac and vascular anatomy than the 2D system routinely used on the space station. The research team also developed a probe for the ultrasound device that better directs the beam, making it possible for someone who is not an expert in sonography to take precise measurements. This technology could help astronauts monitor heart health and treat cardiovascular issues on a long-duration mission to the Moon or Mars. The technology also could help patients on Earth who live in remote locations, where an ultrasound operator may not always be available.

Long-term heart health in space

As part of exploring ways to keep astronauts healthy on missions to the Moon and Mars, NASA is conducting a suite of space station studies called CIPHER that looks at the effects of spaceflight lasting up to a year. One CIPHER study, Vascular Calcium, examines whether calcium lost from bone during spaceflight might deposit in the arteries, increasing vessel stiffness and contributing to increased risk of future cardiovascular disease. Astronaut volunteers provide blood and urine samples and undergo ultrasound and high-resolution scans of their bones and arteries for this investigation. Another CIPHER study, Coronary Responses, uses advanced imaging tests to measure heart and artery response to spaceflight.

These studies will help scientists determine whether spaceflight accelerates narrowing and stiffening of the arteries, known as atherosclerosis, or increases the risk of atrial fibrillation, a rapid and irregular heartbeat seen in middle-aged adults. This work also could help identify potential biomarkers and early warning indicators of cardiovascular disease.

Editor’s note: This release was updated on Jan. 31, 2025. Axiom Mission 4 will launch from Florida no earlier than spring 2025.

NASA and its international partners have approved the crew for Axiom Space’s fourth private astronaut mission to the International Space Station, launching from Florida no earlier than spring 2025.

Peggy Whitson, former NASA astronaut and director of human spaceflight at Axiom Space, will command the commercial mission, while ISRO (Indian Space Research Organization) astronaut Shubhanshu Shukla will serve as pilot. The two mission specialists are ESA (European Space Agency) project astronaut Sławosz Uznański-Wiśniewski of Poland and Tibor Kapu of Hungary.

“I am excited to see continued interest and dedication for the private astronaut missions aboard the International Space Station,” said Dana Weigel, manager of NASA’s International Space Station Program at the agency’s Johnson Space Center in Houston. “As NASA looks toward the future of low Earth orbit, private astronaut missions help pave the way and expand access to the unique microgravity environment.”

The Axiom Mission 4, or Ax-4, crew will launch aboard a SpaceX Dragon spacecraft and travel to the space station. Once docked, the private astronauts plan to spend up to 14 days aboard the orbiting laboratory, conducting a mission comprised of science, outreach, and commercial activities. The mission will send the first ISRO astronaut to the station as part of a joint effort between NASA and the Indian space agency. The private mission also carries the first astronauts from Poland and Hungary to stay aboard the space station.

“Working with the talented and diverse Ax-4 crew has been a deeply rewarding experience,” said Whitson. “Witnessing their selfless dedication and commitment to expanding horizons and creating opportunities for their nations in space exploration is truly remarkable. Each crew member brings unique strengths and perspectives, making our mission not just a scientific endeavor, but a testament to human ingenuity and teamwork. The importance of our mission is about pushing the limits of what we can achieve together and inspiring future generations to dream bigger and reach farther.”

The first private astronaut mission to the station, Axiom Mission 1, lifted off in April 2022 for a 17-day mission aboard the orbiting laboratory. The second private astronaut mission to the station, Axiom Mission 2, also was commanded by Whitson and launched in May 2023 with four private astronauts who spent eight days in orbit. The most recent private astronaut mission, Axiom Mission 3, launched in January 2024; the crew spent 18 days docked to the space station.

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 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. NASA’s goal is to achieve a strong economy in low Earth orbit where the agency can purchase services as one of many customers to meet its science and research objectives in microgravity. NASA’s commercial strategy for low Earth orbit will provide the government with reliable and safe services at a lower cost, enabling 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.

NICER Status Update

Jan. 24, 2025

NASA’s NICER Continues Science Operations Post Repair

NASA crew aboard the International Space Station installed patches to the agency’s NICER (Neutron star Interior Composition Explorer) mission during a spacewalk on Jan. 16. NICER, an X-ray telescope perched near the station’s starboard solar array, resumed science operations later the same day.

The patches cover areas of NICER’s thermal shields where damage was discovered in May 2023. These thin filters block sunlight while allowing X-rays to pass through. After the discovery, the NICER team restricted their observations during the station’s daytime to avoid overwhelming the mission’s sensitive detectors. Nighttime observations were unaffected, and the team was able to continue collecting data for the science community to make groundbreaking measurements using the instrument’s full capabilities.

The repair went according to plan. Data since collected shows the detectors behind the patched areas are performing better than before during station night, and the overall level of sunlight inside NICER during the daytime is reduced substantially.

While NICER experiences less interference from sunlight than before, after analyzing initial data, the team has determined the telescope still experiences more interference than expected. The installed patches cover areas of known damage identified using astronomical observations and from photos taken by both external robotic cameras and astronauts inside the space station. Measurements collected since the repair and close-up, high-resolution photos obtained during the spacewalk are providing new information that may point the way toward further daytime data collection.

In the meantime, NICER continues operations with its full measurement capabilities during orbit night to enable further trailblazing discoveries in time domain and multimessenger astrophysics.

Sunlight ‘Leak’ Impacting NASA’s NICER Telescope, Science Continues

On Tuesday, May 22, NASA’s NICER (Neutron Star Interior Composition Explorer), an X-ray telescope on the International Space Station, developed a “light leak,” in which unwanted sunlight enters the instrument. While analyzing incoming data since then, the team identified an impact to daytime observations. Nighttime observations seem to be unaffected.

The team suspects that at least one of the thin thermal shields on NICER’s 56 X-ray Concentrators has been damaged, allowing sunlight to reach its sensitive detectors.

To mitigate the effects on measurements, the NICER team has limited daytime observations to objects far away from the Sun’s position in the sky. The team has also updated commands to NICER that automatically lower its sensitivity during the orbital day to reduce the effects from sunlight contamination. The team is evaluating these changes and assessing additional measures to reduce the impact on science observations.

To date, more than 300 scientific papers have used NICER observations, and the team is confident that NICER will continue to produce world-class science.

Insights into metal alloy solidification

Researchers report details of phase and structure in the solidification of metal alloys on the International Space Station, including formation of microstructures. Because these microstructures determine a material’s mechanical properties, this work could support improvements in techniques for producing coatings and additive manufacturing or 3D printing processes.

METCOMP, an ESA (European Space Agency) investigation, studied solidification in microgravity using transparent organic mixtures as stand-ins for metal alloys. Conducting the research in microgravity removed the influence of convection and other effects of gravity. Results help scientists better understand and validate models of solidification mechanisms, enabling better forecasting of microstructures and improving manufacturing processes.

The image shows a monochromatic scene with a gradient of brightness transitioning from dark to light. A textured surface appears in the central region.

Measuring the height of upper-atmospheric electrical discharges

Researchers determined the height of a blue discharge from a thundercloud using ground-based electric field measurements and space-based optical measurements from Atmosphere-Space Interactions Monitor (ASIM). This finding helps scientists better understand how these high-altitude lightning-related events affect atmospheric chemistry and could help improve atmospheric models and climate and weather predictions.

ESA’s ASIM is an Earth observation facility that studies severe thunderstorms and upper-atmospheric lighting events and their role in the Earth’s atmosphere and climate. Upper-atmospheric lightning, also known as transient luminous events, occurs well above the altitudes of normal lightning and storm clouds. The data collected by ASIM could support research on the statistical properties of many upper atmosphere lightning events, such as comparison of peak intensities of blue and red pulses with reports from lightning detection networks.

Modeling a complex neutron star

Scientists report that they can use modeling of neutron star PSRJ1231−1411’s X-ray pulses to infer its mass and radius and narrow the possible behaviors of the dense matter at its core. This finding provides a better understanding of the composition and structure of these celestial objects, improving models that help answer questions about conditions in the universe.

The Neutron star Interior Composition Explorer provides high-precision measurements of pulses of X-ray radiation from neutron stars. This particular neutron star presented challenges in finding a fit between models and data, possibly due to fundamental issues with its pulse profile. The authors recommend a program of simulations using synthetic data to determine whether there are fundamental issues with this type of pulse profile that could prevent efforts to obtain tighter and more robust constraints.

Peak Performance in Microgravity

Science in Space January 2025

At the start of a new year, many people think about making positive changes in their lives, such as improving physical fitness or learning a particular skill. Astronauts on the International Space Station work all year to maintain a high level of performance while adapting to changes in their physical fitness, cognitive ability, sensory perception, and other functions during spaceflight.

Research on the space station looks at how these qualities change in space, the ways those changes affect daily performance, and countermeasures to keep astronauts at their peak.

A current CSA (Canadian Space Agency) investigation, Space Health, assesses the effects of spaceflight on cardiovascular deconditioning. The investigation uses Bio-Monitor, wearable sensors that collect data such as pulse rate, blood pressure, breathing rate, skin temperature, and physical activity levels. Results could support development of an autonomous system to monitor cardiovascular health on future space missions. Similar technology could be used to monitor heart health in people on Earth.

Maintaining muscle fitness

During spaceflight, astronauts lose muscle mass and stiffness, an indication of strength. Astronauts exercise daily to counteract these effects, but monitoring the effectiveness of exercise had been limited to before and after flight due to the lack of technologies appropriate for use in space. The ESA (European Space Agency) Myotones investigation demonstrated that a small, non-invasive device accurately measured muscle stiffness and showed that current countermeasures seem to be effective for most muscle groups. Accurate inflight assessment could help scientists target certain muscles to optimize the effectiveness of exercise programs on future missions. The measuring device also could benefit patients in places on Earth without other means for monitoring.

Keeping a sharp mind

Research suggests that the effects of spaceflight on cognitive performance likely are due to the influence of stressors such as radiation and sleep disruption. Longer missions that increase the exposure to these hazards may change how they affect individuals.

Manual Control used a battery of tests to examine how spaceflight affects cognitive, sensory, and motor function right after landing. The day they return from spaceflight, astronauts demonstrate significant impairments in fine motor control and ability to multitask in simulated flying and driving challenges. Researchers attribute this to subtle physiological changes during spaceflight. Performance recovered once individuals were exposed to a task, suggesting that having crew members conduct simulated tasks right before actual ones could be beneficial. This work helps scientists ensure that crew members can safely land and conduct early operations on the Moon and Mars.

Standard Measures collects a set of physical and mental measurements related to human spaceflight risks, including a cognition test battery, from astronauts before, during, and after missions. Using these data, researchers found that astronauts on 6-month missions demonstrated generally stable cognitive performance with mild changes in certain areas, including processing speed, working memory, attention, and willingness to take risks. The finding provides baseline data that could help identify cognitive changes on future missions and support development of appropriate countermeasures. This research includes the largest sample of professional astronauts published to date.

Evaluating perception

Another function that can be affected by spaceflight is sensory perception, such as the ability to interpret motion, orientation, and distance. We use our visual perception of the height and width of objects around us, for example, to complete tasks such as reaching for an object and deciding whether we can fit through an opening. VECTION, a CSA investigation, found that microgravity had no immediate effect on the ability to perceive the height of an object, indicating that astronauts can safely perform tasks that rely on this judgment soon after they arrive in space. Researchers concluded there is no need for countermeasures but did suggest that space travelers be made aware of late-emerging and potentially long-lasting changes in the ability to perceive object height.

Measurements from space support wildfire risk predictions

Researchers demonstrated that data from the International Space Station’s ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) instrument played a significant role in the ability of machine learning algorithms to predict wildfire susceptibility. This result could help support development of effective strategies for predicting, preventing, monitoring, and managing wildfires.

As the frequency and severity of wildfires increases worldwide, experts need reliable models of fire susceptibility to protect public safety and support natural resource planning and risk management. ECOSTRESS measures evapotranspiration, water use efficiency, and other plant-water dynamics on Earth. Researchers report that its water use efficiency data consistently emerged as the leading factor in predicting wildfires, with evaporative stress and topographic slope data also significant.

Combining instruments provides better emissions data

Scientists found that averaging data from the International Space Station’s OCO‐3 and EMIT external instruments can accurately measure the rate of carbon dioxide emissions from power plants. This work could improve emissions monitoring and help communities respond to climate change.

Carbon dioxide emissions from fossil fuel combustion make up nearly a third of human-caused emissions and are a major contributor to climate change. In many places, though, scientists do not know exactly how much carbon dioxide these sources emit. The Orbiting Carbon Observatory-3 or OCO-3 can quantify emissions over large areas and Earth Surface Mineral Dust Source Investigation data can help determine emissions from individual facilities. The researchers suggest future work continue to investigate the effect of wind conditions on measurements.

Thunderstorm phenomena observed from space

Observations by the International Space Station’s Atmosphere-Space Interactions Monitor (ASIM) instrument during a tropical cyclone in 2019 provide insight into the formation and nature of blue corona discharges often observed at the tops of thunderclouds. A better understanding of such processes in Earth’s upper atmosphere could improve atmospheric models and weather and climate predictions.

Scientists do not fully understand the conditions that lead to formation of blue corona discharges, bursts of electrical streamers, which are precursors to lightning. Observations from the ground are affected by scattering and absorption in the clouds. ASIM, a facility from ESA (European Space Agency), provides a unique opportunity for observing these high-atmosphere events from space.

Astronaut Set to Patch NASA’s X-ray Telescope Aboard Space Station

Astronaut Set to Patch NASA’s X-ray Telescope Aboard Space Station

NASA astronaut Nick Hague will install patches to the agency’s NICER (Neutron star Interior Composition Explorer) X-ray telescope on the International Space Station as part of a spacewalk scheduled for Jan. 16. Hague, along with astronaut Suni Williams, will also complete other tasks during the outing.

NICER will be the first NASA observatory repaired on-orbit since the last servicing mission for the Hubble Space Telescope in 2009.

Hague and other astronauts, including Don Pettit, who is also currently on the space station, rehearsed the NICER patch procedures in the NBL (Neutral Buoyancy Laboratory), a 6.2-million-gallon indoor pool at NASA’s Johnson Space Center in Houston, in 2024.

“We use the NBL to mimic, as much as possible, the conditions astronauts will experience while preforming a task during a spacewalk,” said Lucas Widner, a flight controller at KBR and NASA Johnson who ran the NICER NBL sessions. “Most projects outside the station focus on maintenance and upgrades to components like solar panels. It’s been exciting for all of us to be part of getting a science mission back to normal operations.”

From its perch near the space station’s starboard solar array, NICER studies the X-ray sky, including erupting galaxies, black holes, superdense stellar remnants called neutron stars, and even comets in our solar system. 

But in May 2023, NICER developed a “light leak.” Sunlight began entering the telescope through several small, damaged areas in the telescope’s thin thermal shields. During the station’s daytime, the light reaches the X-ray detectors, saturating sensors and interfering with NICER’s measurements of cosmic objects. The mission team altered their daytime observing strategy to mitigate the effect.

The team also developed a plan to cover the largest areas of damage using wedge-shaped patches. Hague will slide the patches into the telescope’s sunshades and lock them into place. 

“We designed the patches so they could be installed either robotically or by an astronaut,” said Steve Kenyon, NICER’s mechanical engineering lead at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “They’re installed using a tool called a T-handle that the astronauts are already familiar with.”

The NBL contains life-size mockups of sections of the space station. Under the supervision of a swarm of scuba divers, a pair of astronauts rehearse exiting and returning through an airlock, traversing the outside of the station, and completing tasks. 

For the NICER repair, the NBL team created a full-scale model of NICER and its surroundings near the starboard solar array. Hague, Pettit, and other astronauts practiced taking the patches out of their caddy, inserting them into the sunshades, locking them into place, and verifying they were secure. 

The task took just under an hour each time, which included the time astronauts needed to travel to NICER, set up their tools, survey the telescope for previously undetected damage, complete the repair, and clean up their tools. 

Practice runs also provided opportunities for the astronauts to troubleshoot how to position themselves so they could reach NICER without touching it too often and for flight controllers to identify safety concerns around the repair.

Being fully submerged in a pool is not the same as being in space, of course, so some issues that arose were “pool-isms.” For example, astronauts sometimes drifted upward while preparing to install the patches in a way unlikely to happen in space. 

Members of the NICER team, including Kenyon and the mission’s principal investigator, Keith Gendreau at NASA Goddard, supported the NBL practice runs. They helped answer questions about the physical aspects of the telescope, as well as science questions from the astronauts and flight controllers. NICER is the leading source of science results on the space station. 

“It was awesome to watch the training sessions and be able to debrief with the astronauts afterward,” Gendreau said. “There isn’t usually a lot of crossover between astrophysics science missions and human spaceflight. NICER will be the first X-ray telescope serviced by astronauts. It’s been an exciting experience, and we’re all looking forward to the spacewalk where it will all come together.”

The NICER telescope is an Astrophysics Mission of Opportunity within NASA’s Explorers Program, which provides frequent flight opportunities for world-class scientific investigations from space utilizing innovative, streamlined, and efficient management approaches within the heliophysics and astrophysics science areas. NASA’s Space Technology Mission Directorate supported the SEXTANT component of the mission, demonstrating pulsar-based spacecraft navigation.

For more than 24 years, NASA has supported a continuous U.S. human presence aboard the International Space Station, advancing scientific knowledge and making research breakthroughs not possible on Earth for the benefit of humanity. The space station is a springboard to NASA’s next great leaps in exploration, including future missions to the Moon under Artemis, and ultimately, human exploration of Mars.

Read more about the groundbreaking work conducted in 2024 aboard the station:

Robot performs remote simulated surgery

On long-duration missions, crew members may need surgical procedures, whether simple stitches or an emergency appendectomy. A small robot successfully performed simulated surgical procedures on the space station in early February 2024 for the Robotic Surgery Tech Demo, using two “hands” to grasp and cut rubber bands simulating tissue. Researchers compare the procedures conducted aboard the station and on Earth to evaluate the effects of microgravity and communication delays between space and ground.

3D metal print in space

On May 30,2024, the ESA (European Space Agency) Metal 3D Printer investigation created a small stainless steel s-curve, the first metal 3D print in space. Crew members on future missions could print metal parts for equipment maintenance, eliminating the need to pack spare parts and tools at launch. This technology also has the potential to improve additive manufacturing on Earth.

The space station orbits roughly 250 miles above and passes over 90 percent of Earth’s population, providing a unique perspective for photographing the planet. Astronauts have taken more than 5.3 million images of Earth to monitor the planet’s changing landscape. The Expedition 71 crew took over 630,000 images, well above the average of roughly 105,000 for a single mission. This year, images included the April solar eclipse and auroras produced as the Sun’s 11-year activity cycle peaks. Others supported response to over 14 disaster events including hurricanes. In addition, 80,000 images were geolocated using machine learning, improving public search capabilities.

Miles of flawless fibers

From mid-February to mid-March of 2024, the Flawless Space Fibers-1 system produced more than seven miles of optical fiber in space. One draw of more than a half mile of fiber surpassed the prior record of 82 feet for the longest fiber manufactured in space, demonstrating that commercial lengths of fiber can be produced in orbit. Fibers produced in microgravity can be superior to those produced in Earth’s gravity. These fibers are made from ZBLAN, a glass alloy with the potential to provide more than 10 times the transmission capacity of traditional silica-based fibers.

Station-tested radiation technology flown on Artemis I

The Orion spacecraft carried 5,600 passive and 34 active radiation detectors on its Artemis I uncrewed mission around the Moon in November 2022. Some of these devices previously were tested on the space station: HERA (Hybrid Electronic Radiation Assessor), which detects radiation events such as solar flares; the ESA (European Space Agency) Active Dosimeters, a wearable device collecting real-time data on individual radiation doses; and the AstroRad Vest, a garment to protect radiation-sensitive organs and tissues. In 2024, researchers released evaluation of data collected in 2022 by these tools that indicate the Orion spacecraft can protect astronauts on lunar missions from potentially hazardous radiation. The orbiting laboratory remains a valuable platform for testing technology for missions beyond Earth’s orbit.

In December 2024, five CubeSats deployed into Earth’s orbit from the International Space Station. Among them was LignoSat, a wooden satellite from JAXA (Japanese Aerospace Exploration Agency) that investigates the use of wood in space. Findings could offer a more sustainable alternative to conventional satellites.

A previous experiment aboard station exposed three species of wood to the space environment to help researchers determine the best option for LignoSat. The final design used 10 cm long honoki magnolia wood panels assembled with a Japanese wood-joinery method.

Researchers will use sensors to evaluate strain on the wood and measure its responses to temperature and radiation in space. Geomagnetic levels will also be monitored to determine whether the geomagnetic field can penetrate the body of the wooden satellite and interfere with its technological capabilities. Investigating uses for wood in space could lead to innovative solutions in the future.

An open box is made of four wooden panels. One additional panel is to the side. The edge of the additional panel matches up with the open box, like a jigsaw puzzle.
A traditional Japanese wooden joining method, the Blind Miter Dovetail Joint, is used for LignoSat to connect two wooden panels without using glue or nails.
