The launch, on June 16th, 2010, of Soyuz flight TMA-19, was the 100th mission to count as part of the International Space Station project (it was also the 106th Soyuz launch).
The crew of TMA-19 were Russian commander Fyodor Yurchikhin, and American flight engineers Shannon Walker and Douglas Wheelock. These three formed half of the ISS Expedition 24 crew, and between them they have an impressive record of time spent in space. Early astronauts, even those who’ve been to the Moon and back, spent very little time beyond the atmosphere. Neil Armstrong managed 8 days 14 hours, and Buzz Aldrin 12 days. But the days of Space Station missions mean astronauts can end up spending years off the planet. For the crew of TMA-19 the figures are: 672 days for Yurchikhin, 178 days for Wheelock and 163 days for Walker.
