The International Space Station welcomed three new guests on Saturday, with NASA astronaut Scott Kelly and Russian cosmonauts Gennady Padalka and Mikhail Kornienko making the six-hour flight from Kazakhstan to the ISS. NASA released a 15-minute video of the three men boarding the ISS and being greeted by the crew already onboard.
Kelly, Padalk and Kornienko are part of Expedition 43, a significant expedition that will see Kelly and Kornienko remain on the ISS for a full year to conduct extensive research on the effects of long-term space travel on the human body. Most astronauts spend just six months on the ISS during their expeditions. The research will help NASA and other space agencies better understand the effects of space travel for manned missions to Mars.
The three new astronauts will join station Commander Terry Virts of NASA and flight engineers Anton Shkaplerov of Roscosmos and Samantha Cristoforetti of the European Space Agency, who will serve as their crewmates for the next several months. Check out the video above, which shows the new crew greeting the old and some touching footage of the crew members talking with their families back home.
