On Saturday (Aug. 24), NASA revealed its long-awaited strategy to bring astronauts Butch Wilmore and Sunita Williams home from the International Space Station (ISS) no earlier than February 2025– a minimum of 8 months longer than the preliminary eight-day journey they registered for.
The return flight– which will ditch the struggling Boeing Starliner spacecraft that the team rode to the ISS, in favor of a SpaceX car– has actually no validated date. In the best-case circumstance of an early-February return, the Starliner team’s time in area will amount to no less than 240 successive days considering that the spacecraft’s launch on June 5, 2024. A March departure might bump that number approximately almost 270 days.
8 straight months in area seems like a lot, however it’s far from a brand-new record. Astronauts usually invest approximately 6 months aboard the ISS, where they perform experiments and keep the spaceport station before going back to Earth, according to Live Science’s sibling website Space.comObjectives can extend numerous months longer, for a range of factors, consisting of long-duration experiments and unexpected occurrences.
Who has invested the longest time in area?
The record for the most successive days in area by an American goes to astronaut Frank Rubio, who invested 371 days aboard the ISS from September 2022 to September 2023.
Rubio was at first anticipated home in March 2023, however his remain in area more than doubled after a little meteoroid or piece of area scrap knocked into the Russian Soyuz spacecraft that was suggested to bring him home in December 2022, triggering irreversible damage. Rubio, together with Russian cosmonauts Sergey Prokopyev and Dmitri Petelin, needed to wait another 6 months in area before a replacement Soyuz pill got here to bring them home.

While Prokopyev and Petelin likewise clocked 371 successive days in area, they did not break any Russian records. Cosmonaut Valeri Polyakov– who holds the record for the most successive days invested in area by any human– worked aboard Russia’s now-defunct Mir spaceport station for 437 days, or more than 14 months, from January 1994 to March 1995. Polyakov offered for this objective as part of a research study of the results of long-lasting spaceflight on human health.
Other significant long-haul remain in area consist of American astronaut Christina Koch‘s 328 days aboard the ISS from March 2019 to February 2020– the longest single spaceflight by a lady– and American astronaut Scott Kelly’s 340 days in area from March 2015 to March 2016.
How does area impact the body?
Kelly’s prolonged spaceflight– which exceeded at the time however has actually now been gone beyond numerous times– became part of NASA’s groundbreaking twins research studywhich compared Kelly’s physical and psychological health pre- and post-spaceflight to the standard health of his twin sibling Mark Kelly, a retired astronaut and present Arizona senator who stayed in the world throughout his bro’s time in orbit.
The twin research study exposed that astronauts experience a variety of modifications throughout long remain in orbit, consisting of modifications in gene expression, body weight and gut microbiome structure. It contributed to a still-growing body of research study that reveals that astronauts who invest prolonged quantities of time in microgravity are likewise most likely to experience short-term health effects such as muscle and bone loss, vision issues, lower resistance, an increased threat of embolism and swelling, and DNA damage. The majority of these modifications go back to typical after 6 months back in the world, scientists have actually discovered. The research study of spaceflight on human health is still in its infancy.
While Williams and Wilmore invest the next 5 to 6 months in area, they might experience a few of these short-term modifications, in addition to modifications in psychological health related to seclusion and monotonyprevious research study recommends. Their extended stay in area is barely unmatched– and much more secure than sending out the set home on a spacecraft with unsettled technical concerns.
On its method to the ISS in June, Starliner sprung numerous helium leakages and revealed concerns with
numerous of its smaller sized thrusters
The craft docked securely with the spaceport station, however months of screening have actually been not able to solve the concerns with certainty. On Aug. 24, NASA authorities revealed that, in the interest of security, Starliner will undock from the ISS without a team in early September, sending it back to Earth empty while Williams and Wilmore await their trip home in 2025.
Editor’s note: This post was upgraded on Aug. 27 to fix a mistake mentioning that Starliner had a variety of hydrogen leakages. They remained in truth helium leakages.
