NASA SpaceX Crew-12 Returns After 237 Days: Mission Facts for Exams

NASA's SpaceX Crew-12 mission ended on 8 October 2026, when the Crew Dragon capsule Freedom splashed down in the Pacific Ocean off the California coast. The crew had launched on 13 February 2026 for the International Space Station (ISS). As of 10 October 2026 the mission is completed. The return is a useful current-affairs item on human spaceflight, ISS research and space terminology.

What happened and when

The return was reported in two sources. NASA's mission page lists the landing at 11:34 a.m. on 8 October 2026, and a NASA blog headline gives the time as EDT. GKToday gives 8:34 a.m. Pacific Daylight Time. These are the same moment in different time zones. Converted to Indian Standard Time, that is about 9:04 p.m. on 8 October (our conversion, not a figure from either source).

The dates to keep apart are these:

• Launch: 13 February 2026 (NASA's page lists 5:15 a.m.; it does not state the time zone).
• Docking: the following day, per GKToday.
• Undocking: NASA's blog is dated 7 October 2026.
• Splashdown: 8 October 2026.
• GKToday article date: 10 October 2026, two days after the event.

NASA's mission page was last updated on 8 October 2026.

Crew-12 at a glance

The 237-day figure matches the count of days from 13 February to 8 October. GKToday describes it as time aboard the ISS, while NASA's page gives only the launch and landing times. Treat it as the overall mission duration.

Who flew before

According to GKToday, Meir and Fedyaev had already been to space. Hathaway and Adenot were on their first missions.

Research carried out in microgravity

GKToday lists several investigations from the mission:

• producing stem cells in space;
• technology to make intravenous fluids on demand;
• how pneumonia-causing bacteria may contribute to heart damage;
• nutrition and factors affecting blood flow during spaceflight.

The on-demand IV fluid work matters for long missions far from Earth, where resupply is limited. The article says the research is relevant to planned crewed exploration of the Moon and Mars. The sources give no results or findings from these studies, so this post does not report any.

Spacewalks and the term EVA

A spacewalk, formally called extravehicular activity (EVA), is work done outside a spacecraft or station by an astronaut in a spacesuit. According to GKToday:

• Meir completed four spacewalks on this mission, bringing her career total to seven. The article ranks her third among NASA women for career spacewalks, after Peggy Whitson and Suni Williams.
• Adenot completed three spacewalks and became the first French woman to conduct a spacewalk outside the ISS.

These records come from GKToday alone. The NASA page supplied here does not confirm them.

Exam-relevant context

Questions on this kind of news usually test the concept and the terminology rather than the minute-by-minute timeline. The sources support the following points. Nothing here suggests that any question will appear in a particular exam.

• The ISS is a permanently crewed research laboratory in low Earth orbit.
• Microgravity research lets scientists study biological and physical processes under conditions different from those on Earth.
• EVA is the formal term for work outside a spacecraft or station.
• The European Space Agency (ESA) is an intergovernmental organisation for space activities.
• NASA's Johnson Space Center is in Houston, Texas. After splashdown the crew underwent medical evaluations before travelling there, per GKToday.
• The crew was international: two NASA astronauts, one from ESA and one Roscosmos cosmonaut.

What the evidence does not cover

• Neither source mentions any Indian astronaut or Indian experiment on Crew-12, so this post draws no India-specific link.
• No sources describe the crew's health or condition after the medical checks. Whether they have reached Houston is not confirmed.
• The orbit count, distance travelled and spacewalk rankings rest on a single secondary source.
• NASA's page labels the splashdown release link with the words "Crew-11", although the link itself is for Crew-12. This looks like a labelling slip on the page, and the dates and crew names used here are consistent with Crew-12.

FAQ

When did Crew-12 return to Earth?

The capsule splashed down on 8 October 2026 at 11:34 a.m. EDT (8:34 a.m. PDT). The mission was complete as of 10 October 2026.

Who were the Crew-12 astronauts?

The crew was NASA's Jessica Meir and Jack Hathaway, ESA's Sophie Adenot and Roscosmos cosmonaut Andrey Fedyaev. NASA lists Meir as commander and Hathaway as pilot.

Why does the 237-day figure matter?

It shows the length of a long-duration ISS mission, which is the kind of flight that produces microgravity health research relevant to future Moon and Mars exploration, as GKToday notes.
