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.

O’Hara, wearing a dark blue sleeveless t-shirt, smiles at the camera. Her right hand is touching the front of a large silver box built into a wall, with lights above it and a clear panel that reveals part of a circular sample holder that resembles an old film reel. There is a panel of switches below her hand and several large cameras on the wall behind her.

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.

Record participation in Fifth Robo-Pro Challenge

A record 661 teams and 2,788 applicants from thirteen countries, regions, and organizations participated in the fifth Kibo Robo-Pro Challenge, which wrapped its final round in September. This educational program from JAXA (Japan Aerospace Exploration Agency) has students solve various problems by programming free-flying Astrobee robots aboard the space station. Participants gain hands-on experience with space robot technology and software programming and interact with others from around the world.

      By NASA
      NASA astronaut Christopher Williams poses for a portrait at NASA’s Johnson Space Center in Houston, Texas.Credit: NASA NASA astronaut Chris Williams will embark on his first mission to the International Space Station, serving as a flight engineer and Expedition 74 crew member.
      Williams will launch aboard the Roscosmos Soyuz MS-28 spacecraft in November, accompanied by Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev. After launching from the Baikonur Cosmodrome in Kazakhstan, the trio will spend approximately eight months aboard the orbiting laboratory.
      During his expedition, Williams will conduct scientific investigations and technology demonstrations that help prepare humans for future space missions and benefit humanity.
      Selected as a NASA astronaut in 2021, Williams graduated with the 23rd astronaut class in 2024. He began training for his first space station flight assignment immediately after completing initial astronaut candidate training.
      Williams was born in New York City, and considers Potomac, Maryland, his hometown. He holds a bachelor’s degree in Physics from Stanford University in California and a doctorate in Physics from the Massachusetts Institute of Technology in Cambridge, where his research focused on astrophysics. Williams completed Medical Physics Residency training at Harvard Medical School in Boston. He was working as a clinical physicist and researcher at the Brigham and Women’s Hospital in Boston when he was selected as an astronaut.
      For more than two decades, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and making research breakthroughs not possible on Earth. The station is a critical testbed for NASA to understand and overcome the challenges of long-duration spaceflight and to expand commercial opportunities in low Earth orbit. As commercial companies focus on providing human space transportation services and destinations as part of a robust low Earth orbit economy, NASA is able to more fully focus its resources on deep space missions to the Moon and Mars.

      What Are the Dangers of Going to Space? We Asked a NASA Expert: Episode 55
      By NASA
      2 min read
      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      What are the dangers of going to space?

      For human spaceflight, the first thing I think about is the astronauts actually strapping themselves to a rocket. And if that isn’t dangerous enough, once they launch and they’re out into space in deep exploration, we have to worry about radiation.

      Radiation is coming at them from all directions. From the Sun, we have solar particles. We have galactic cosmic rays that are all over in the universe. And those cause damage to DNA. On Earth here, we use sunscreen to protect us from DNA damage. Our astronauts are protected from the shielding that’s around them in the space vehicles.

      We also have to worry about microgravity. So what happens there? We see a lot of bone and muscle loss in our astronauts. And so to prevent this, we actually have the astronauts exercising for hours every day. And of course we don’t want to run out of food on a space exploration mission. So we want to make sure that we have everything that the astronauts need to take with them to make sure that we can sustain them.

      There are many risks associated with human space exploration. NASA has been planning for these missions to make our astronauts return home safely.
