Expedition 64 – Space Station

NASA Completes Analysis of Recovered Space Object

In March 2021, NASA ground controllers used the International Space Station’s robotic arm to release a cargo pallet containing aging nickel hydride batteries from the space station following the delivery and installation of new lithium-ion batteries as part of power upgrades on the orbital outpost. The total mass of the hardware released from space station was about 5,800 pounds.

The hardware was expected to fully burn up during entry through Earth’s atmosphere on March 8, 2024. However, a piece of hardware survived re-entry and impacted a home in Naples, Florida. NASA collected the item in cooperation with the homeowner and analyzed the object at the agency’s Kennedy Space Center in Florida.

Recovered stanchion from the NASA flight support equipment used to mount International Space Station batteries on a cargo pallet. The stanchion survived re-entry through Earth’s atmosphere on March 8, 2024, and impacted a home in Naples, Florida

As part of the analysis, NASA completed an assessment of the object’s dimensions and features compared to the released hardware and performed a materials analysis. Based on the examination, the agency determined the debris to be a stanchion from the NASA flight support equipment used to mount the batteries on the cargo pallet. The object is made of the metal alloy Inconel, weighs 1.6 pounds, is 4 inches in height and 1.6 inches in diameter.

The International Space Station will perform a detailed investigation of the jettison and re-entry analysis to determine the cause of the debris survival and to update modeling and analysis, as needed. NASA specialists use engineering models to estimate how objects heat up and break apart during atmospheric re-entry. These models require detailed input parameters and are regularly updated when debris is found to have survived atmospheric re-entry to the ground.

NASA remains committed to responsibly operating in low Earth orbit, and mitigating as much risk as possible to protect people on Earth when space hardware must be released.

NASA astronaut Kate Rubins and cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov of Roscosmos landed on Earth at 12:55 a.m. EDT Saturday, April 17 in Kazakhstan. The trio departed the International Space Station in their Soyuz MS-17 spacecraft at 9:34 p.m.

After post-landing medical checks, the crew will split up with Rubins returning to her home in Houston, while the cosmonauts fly back to their training base in Star City, Russia.

Remaining aboard the station is the seven-person crew of Expedition 65, with new station commander Shannon Walker of NASA, NASA astronauts Victor Glover, Michael Hopkins, and Mark Vande Hei, Japan Aerospace Exploration Agency (JAXA) astronaut Soichi Noguchi, and cosmonauts Oleg Novitskiy and Pyotr Dubrov.

Later this month, NASA’s SpaceX Crew-2 members – NASA astronauts Shane Kimbrough and Megan McArthur, JAXA astronaut Akihiko Hoshide, and ESA (European Space Agency) astronaut Thomas Pesquet – will join the Expedition 65 members aboard the station. Crew-2 will be the second long-duration mission to fly as part of NASA’s Commercial Crew Program, continuing to provide the capability of regularly launching humans from American soil.

In November 2020, the International Space Station surpassed a 20-year milestone of continuous human presence, providing opportunities for unique technological demonstrations and research that help prepare for long-duration missions to the Moon and Mars while also improving life on Earth. To date, 243 people from 19 countries have visited the orbiting laboratory that has hosted nearly 3,000 research investigations from researchers in 108 countries and areas.

NASA Television and the agency’s website are now broadcasting live coverage of the return to Earth of NASA astronaut Kate Rubins and cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov of the Russian space agency Roscosmos. The Soyuz MS-17 spacecraft carrying the trio will make its deorbit burn to set the spaceship on its re-entry through Earth’s atmosphere for a landing in Kazakhstan at 12:56 a.m. (10:56 a.m. Kazakhstan time) Saturday, April 17.

During the 185-day mission, Rubins spent hundreds of hours working on new space station experiments, building on investigations she conducted during her first mission, including heart research and multiple microbiology studies. She advanced her work in DNA sequencing, which could allow astronauts to diagnose an illness in space or identify microbes growing at the space station. Rubins collected hundreds of microbial samples at different locations within the space station for the 3DMM study to construct a 3D map of bacteria and bacterial products throughout the station. By advancing understanding of the orbiting laboratory’s microbiome, this work helps identify potential risks and supports developing countermeasures to mitigate those risks.

Rubins also worked on the Cardinal Heart experiment, which studies how changes in gravity affect cardiovascular cells at the cellular and tissue levels. Results could provide new understanding of heart problems on Earth, help identify new treatments, and support development of screening measures to predict cardiovascular risk prior to spaceflight.
