UK Science Minister Amanda Solloway remembers Peake's Dec. 15, 2015 mission to the ISS as a turning point for British space exploration.

How long was Tim Peake on the ISS?

Tim finished his 186-day Principia mission working on the International Space Station for Expedition 46/47 when he landed back on Earth 18 June 2016.

Who was on the ISS for the longest?

Before Vande Hei's long stay in space, the longest spaceflight by an American was held by Scott Kelly, who spent 340 days at the ISS in 2015–16. However. Russian cosmonaut Valeri Polyakov spent 437 days on the Mir space station from 1994 and 1995 still holds the record for the longest time a person has stayed in space.
