It's a far cry from the duration called for by most Mars mission architectures, but this is a large step forward. Astronaut Scott Kelly will set a new duration record for American astronauts, while cosmonaut Mikhail Kornienko will spend more time in space than any Russian since the deorbiting of Mir.
The third passenger on their Soyuz flight to the ISS, Gennady Padalka, has been practically forgotten by the media. Padalka will only spent the normal six months on orbit, but upon landing will emerge with the human time-in-space record.
Of course, it's not all butterflies and rainbows. Kelly and Kornienko will occupy slots that could have been assigned to other astronauts and cosmonauts, delaying when they get more flight assignments. Considering how much more science year-long missions will yield, it's entirely possible this is the new normal. However, the astronaut corps has shrunk significantly in the post-shuttle years, so I may be worrying about a non-issue.
Altogether, this is a very exciting time in our push to the planets. Let's hope for a nominal launch.
