The 100-day countdown begins today for ESA astronaut Andreas Mogensen’s visit to the International Space Station.

The 100-day countdown begins today for ESA astronaut Andreas Mogensen’s visit to the International Space Station. Following launch on 1 September, he will test new technologies and deliver a fresh spacecraft for the long-stay crew already aboard the orbital complex.
Most Station astronauts stay for up to six months, but NASA’s Scott Kelly and Russia’s Mikhail Korniyenko are spending almost a year in space to research the effects of living in weightlessness for a long time.
All occupants arrive in a Russian Soyuz spacecraft that is certified for six months, so Scott and Mikhail need a new vehicle to fly home when their mission ends next year.

 Andreas and his crewmates will fly to the Station in Soyuz TMA-18M but return to Earth aboard Soyuz TMA-16M, which delivered Mikhail and Scott to the weightless research laboratory.
