Three astronauts return to Earth after 168 days in space
After spending 168 days aboard the International Space Station, NASA astronauts Joe Acaba and Mark Vande Hei landed in Kazakhstan along with Russian cosmonaut Alexander Misurkin. Vande Hei ventured outside ISS on four spacewalks while Acaba and Misurkin conducted one spacewalk apiece. Misurkin's spacewalk, lasting 8 hours and 13 minutes to fix an antenna, was the longest for any Russian.
