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.

O’Hara is wearing a gray hooded sweatshirt and smiling at the camera, as she holds the miniature robot with both hands. The robot is narrow, about the size of an adult’s forearm, with a gray handle that has up and down arrow buttons and two bent “arms” on its end. One of the arms has a metal spatula and the other a set of clippers.

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.

Here’s looking at you, 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.

Tell-tale heart

In May 2024, BFF-Cardiac successfully bioprinted a three-dimensional human heart tissue sample using the Redwire BioFabrication Facility. Tissues bioprinted in the microgravity of the space station hold their shape without the use of artificial scaffolds. These bioprinted human heart tissues eventually could be used to create personalized patches for tissue damaged by events such as heart attacks. The tissue sample is undergoing further testing on Earth.

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.

The vest, closed by two buckle straps, is dark blue with a gray stripe from the bottom up to the shoulder, and small patches of the American and Israeli flags and StemRad and Lockheed Martin logos. The seven windows of the cupola are visible behind it and, through them, Earth below.

      Kennedy Space Center Director and charter members of the Florida University Space Research Consortium signed a memorandum of understanding on Jan. 8, 2025. From left: Jennifer Kunz, Associate Director, Technical, Kennedy Space Center; Kelvin Manning, Deputy Director, Kennedy Space Center; Dr. Kent Fuchs, Interim President, University of Florida; Janet Petro, Director, Kennedy Space Center; Jeanette Nuñez, Florida Lieutenant Governor; Dr. Alexander Cartwright, President, University of Central Florida; Dr. Barry Butler, President, Embry-Riddle Aeronautical University. NASA/Kim Shiflett The future of research and technology at NASA’s Kennedy Space Center in Florida is expanding Wednesday, as Kennedy’s center director and charter members in the Florida University Space Research Consortium signed a memorandum of understanding in research and development to assist with missions and contribute to NASA’s Moon to Mars exploration approach.
      Officials from the consortium – designated in 2024 as the state’s official space research entity – NASA leaders, and guests participated in the signing ceremony held at Kennedy, marking a critical milestone in a partnership to advance research, technology development, education, and communication between the spaceport and the state’s growing space industry.
      “Through this agreement, NASA will benefit in new and exciting ways from our longtime partnership with the universities that make Florida shine,” said NASA Administrator Bill Nelson. “As we move deeper into this golden era of space exploration, a new generation of thinkers and leaders will lead the way – thinkers and leaders like the researchers, faculty, and students of the Artemis Generation, whom we are pleased to work with through the consortium.”
      The creation of the consortium was the result of more than a year of effort by leaders at Kennedy, the University of Florida, the University of Central Florida, and Embry-Riddle Aeronautical University. The agreement highlights the partnership and serves as the official start to partnering activities, with Florida now the only state with a university consortium affiliated with one of NASA’s centers.
      Present at the event was Florida Governor Ron DeSantis. “It was great to visit the Space Coast Jan. 8 to announce the Florida University Space Research Consortium—our state’s official space research entity. Home to a thriving aerospace industry and world-class higher education institutions, Florida is the ideal place to launch this initiative. We are primed to lead the nation in developing a blueprint for state-space partnerships into the future.”
      The mission of the consortium is to foster a symbiotic relationship between NASA Kennedy and Florida’s universities to drive innovation in space exploration, research, and technology through academic collaboration, joint projects, and workforce development.
      “The launch of the Florida University Space Research Consortium is a significant milestone for our state’s aerospace sector, bringing together our world-class education system with cutting edge research and development,” said Lieutenant Governor Jeanette Nuñez. “This consortium will undoubtedly further strengthen and deepen Florida’s position as the leader in the global aerospace economy.”
      The memorandum of understanding marks the dawn of a new era of cooperation between the Florida spaceport and the state’s university system, starting with the three charter universities with plans to expand to other state universities interested in participating. The push to enhance research and technological collaboration with universities has been a priority at NASA for years and has seen success at other NASA centers across the country.
      While Kennedy becomes the first NASA center affiliated with a university consortium, recently NASA’s Ames Research Center in California’s Silicon Valley partnered with University of California, Berkeley, on development of the Berkeley Space Center at NASA Research Park, located at Ames. Still in development, the project is envisioned as a 36-acre discovery and innovation hub to include educational spaces, labs, offices, student housing, and a new conference center. More recently, NASA’s Johnson Space Center in Houston teamed up with Texas A&M University to break ground on a building that will become a testing laboratory for apparatuses in development for NASA’s Moon to Mars plans. In attendance for the groundbreaking was Kennedy Space Center Director Janet Petro, who was one of the signatories on the agreement.
      NASA’s Kennedy Space Center Director Janet Petro signs a memorandum of understanding between Kennedy Space Center and the Florida University Space Research Consortium on Jan. 8, 2025. NASA/Kim Shiflett “This agreement is a shining example of what it looks like when we link arms and create a space for the whole to be greater than all our parts,” said Petro. “This symbiotic partnership makes way for collaborative research opportunities and increased exposure to advanced technology, significantly enhancing NASA’s research output in fields such as aerospace engineering, materials science, robotics, and environmental science, all of which are necessary for long-term human exploration as we learn to live and work deeper into space than ever before.”

      A Rover Retrospective: Turning Trials to Triumphs in 2024
      A look back at a few Mars 2020 mission highlights of 2024  
      Perseverance’s past year operating on the surface of Mars was filled with some of the mission’s highest highs, but also some of its greatest challenges. True to its name and its reputation as a mission that overcomes challenges, Perseverance and its team of scientists and engineers turned trials to triumphs in yet another outstanding year for the mission. There’s a lot to celebrate about Perseverance’s past year on Mars, but here are three of my top mission moments this year, in the order in which they happened. 
      1. SHERLOC’s cover opens 
      NASA’s Mars Perseverance rover captured this image of its SHERLOC instrument (Scanning Habitable Environments with Raman & Luminescence for Organics and Chemicals), showing the cover mechanism of SHERLOC’s Autofocus and Context Imager camera (ACI) in a nearly open configuration. The rover acquired this image using its Left Mastcam-Z camera — one of a pair of cameras located high on the rover’s mast — on March 3, 2024 (sol 1079, or Martian day 1,079 of the Mars 2020 mission), at the local mean solar time of 12:18:41. NASA/JPL-Caltech/ASU In early January the SHERLOC instrument’s cover mechanism stopped responding during a routine attempt to acquire data on a rock outcrop in the Margin unit. After six weeks of team diagnostics, the SHERLOC instrument was declared offline and many of us feared that the instrument had met its end. In early March, the team made significant progress in driving the cover to a more open position. Then, to everyone’s surprise, the SHERLOC cover moved unexpectedly to a nearly completely open position during a movement of the arm on sol 1077. I remember staring in wonder at the image of the cover (taken on sol 1079), feeling real optimism for the first time that SHERLOC could be recovered. The team spent the next few months developing a new plan for operating SHERLOC with its cover open, and the instrument was declared back online at the end of June.  
      2. A potential biosignature at Cheyava Falls  
      NASA’s Perseverance Mars rover captured this image of “leopard spots” on a rock nicknamed “Cheyava Falls” on July 18, 2024 — sol 1212. or the 1,212th Martian day of the mission. Running the length of the rock are large white calcium sulfate veins. Between those veins are bands of material whose reddish color suggests the presence of hematite, one of the minerals that gives Mars its distinctive rusty hue. Scientists are particularly interested in the millimeter-size, irregularly shaped light patches on the central reddish band (from lower left to upper right of the image) that resemble leopard spots. Perseverance captured the image using a camera called WATSON (Wide Angle Topographic Sensor for Operations and eNgineering), part of the SHERLOC (Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals) instrument suite located on the end of Perseverance’s robotic arm. NASA/JPL-Caltech/MSSS No top list would be complete without Perseverance’s discovery in July 2024 of a potential biosignature in the form of sub-millimeter-scale “leopard spots” at an outcrop called Cheyava Falls. These features, which formed during chemical reactions within the rock, have dark rims and light cores and occur together with organic carbon. On Earth, these chemical reactions are often driven by or associated with microbes. Although we can’t say for sure that microbes were involved in the formation of the leopard spots at Cheyava Falls, this question can be answered when Perseverance’s samples are returned to Earth. In the meantime, this rock remains one of the most compelling rocks discovered on Mars.  
      3. Arrival at Witch Hazel Hill 
      NASA’s Mars Perseverance rover acquired this image at the top of Witch Hazel Hill, of the South Arm and Minnie Hill outcrops. Perseverance used its Left Navigation Camera (Navcam) — which also aids in driving — located high on the rover’s mast. The rover captured the image on Dec. 16, 2024 (sol 1359, or Martian day 1,359 of the Mars 2020 mission), at the local mean solar time of 13:26:38. NASA/JPL-Caltech Closing out 2024 on a high note, in mid-December Perseverance arrived at the top of a sequence of rock exposed on the western edge of the Jezero crater rim called Witch Hazel Hill. These rocks pre-date the formation of Jezero crater and could be amongst the oldest rocks exposed on the surface of Mars. These rocks have the potential to tell us about a period of solar system history not well-preserved on our own planet Earth, and they may record important clues about the early history and habitability of Mars. Witch Hazel Hill first caught my attention during landing site selection several years ago, when we were debating the merits of landing Perseverance in Jezero versus sites outside the crater. At the time, this area seemed just out of reach for a Jezero-focused mission, so I’m thrilled that the rover is now exploring this site!   
      The Mars 2020 mission had its ups and downs and a fair share of surprises during 2024, but we are looking ahead to 2025 with excitement, as Perseverance continues to explore and sample the Jezero crater rim.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      The Radiation Tolerant Computer, or RadPC, payload undergoes final checkout at Montana State University in Bozeman, which leads the payload project. RadPC is one of 10 NASA payloads set to fly aboard the next delivery for NASA’s CLPS (Commercial Lunar Payload Services) initiative in 2025. RadPC prototypes previously were tested aboard the International Space Station and Earth-orbiting satellites, but the technology demonstrator will undergo its biggest trial in transit to the Moon – passing through the Earth’s Van Allen radiation belts – and during its roughly two-week mission on the lunar surface. Photo courtesy Firefly Aerospace Onboard computers are critical to space exploration, aiding nearly every spacecraft function from propulsion and navigation systems to life support technology, science data retrieval and analysis, communications, and reentry.
      But computers in space are susceptible to ionizing solar and cosmic radiation. Just one high-energy particle can trigger a so-called “single event effect,” causing minor data errors that lead to cascading malfunctions, system crashes, and permanent damage. NASA has long sought cost-effective solutions to mitigate radiation effects on computers to ensure mission safety and success.
      Enter the Radiation Tolerant Computer (RadPC) technology demonstration, one of 10 NASA payloads set to fly aboard the next lunar delivery for the agency’s CLPS (Commercial Lunar Payload Services) initiative. RadPC will be carried to the Moon’s surface by Firefly Aerospace’s Blue Ghost 1 lunar lander.
      Developed by researchers at Montana State University in Bozeman, RadPC aims to demonstrate computer recovery from faults caused by single event effects of ionizing radiation. The computer is designed to gauge its own real-time state of health by employing redundant processors implemented on off-the-shelf integrated circuits called field programmable gate arrays. These tile-like logic blocks are capable of being easily replaced following a confirmed ionizing particle strike. In the event of a radiation strike, RadPC’s patented recovery procedures can identify the location of the fault and repair the issue in the background.
      As an added science benefit, RadPC carries three dosimeters to measure varying levels of radiation in the lunar environment with each tuned to different sensitivity levels. These dosimeters will continuously measure the interaction between Earth’s magnetosphere and the solar wind during its journey to the Moon. It will also provide detailed radiation information about Blue Ghost’s lunar landing site at Mare Crisium, which could help to safeguard future Artemis astronauts.
      “This is RadPC’s first mission out into the wild, so to speak,” said Dennis Harris, who manages the payload for the CLPS initiative at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “The RadPC CLPS payload is an exciting opportunity to verify a radiation-tolerant computer option that could make future Moon to Mars missions safer and more cost-effective.”
      Under the CLPS model, NASA is investing in commercial delivery services to the Moon to enable industry growth and support long-term lunar exploration. As a primary customer for CLPS deliveries, NASA aims to be one of many customers on future flights. Marshall manages the development of seven of the 10 CLPS payloads carried on Firefly’s Blue Ghost lunar lander.

      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. 
      NASA astronaut Nick Hague holds a patch for NICER (Neutron star Interior Composition Explorer) at the end of a T-handle tool during a training exercise on May 16, 2024, in the NBL (Neutral Buoyancy Laboratory) at NASA’s Johnson Space Center in Houston. NASA/NBL Dive Team Astronaut Nick Hague removes a patch from the caddy using a T-handle tool during a training exercise in the NBL at NASA Johnson on May 16, 2024. The booklet on his wrist has a schematic of the NICER telescope and where the patches will go.NASA/NBL Dive Team “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. 
      UAE (United Arab Emirates) astronaut Sultan Alneyadi captured this view of NICER from a window in the space station’s Poisk Mini-Research Module 2 in July 2023. Photos like this one helped the NICER team map the damage to the telescope’s thermal shields.NASA/Sultan Alneyadi Some of NICER’s damaged thermal shields (circled) are visible in this photograph.NASA/Sultan Alneyadi 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.

      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.
