Tim Peake spent 186 days in space during his Principia mission aboard the International Space Station.

Mission Timeline

Launched on December 15, 2015, via Soyuz TMA-19M from Baikonur Cosmodrome, Peake joined Expedition 46/47 with crewmates Tim Kopra and Yuri Malenchenko. He returned to Earth on June 18, 2016, landing in Kazakhstan after orbiting roughly 3,000 times and traveling 125 million kilometers. This marked him as the first British ESA astronaut on the ISS, a milestone that captivated the UK public nearly a decade ago.

Key Achievements

  • Conducted a spacewalk in January 2016 to repair the ISS power system.
  • Ran over 250 scientific experiments, including remote Mars rover control and spacecraft docking assistance.
  • "Raced" the London Marathon on the ISS treadmill, engaging 1.6 million European schoolchildren in outreach.

These feats highlighted his Army pilot background—over 3,000 flight hours—blending grit with innovation in microgravity.

Precise Duration

185 days, 22 hours, and 11 minutes total, per official logs, wrapping up a "huge privilege" as Peake later reflected post-landing.

TL;DR: Tim Peake's single spaceflight lasted 186 days (Dec 2015–Jun 2016), packed with experiments and a historic spacewalk.
