CAPE CANAVERAL, Fla. -- After a weeklong trip turned into a nine-month stay aboard the International Space Station, NASA astronauts Suni Williams and Butch Wilmore are finally coming home. The pair may leave the station as early as Sunday, weather permitting, and if their replacements arrive as scheduled. Crew-10, composed of Spokane's Anne McClain, fellow NASA astronaut Nichole Ayers, Roscosmos cosmonaut Kirill Peskov and Japanese astronaut Takuya Onishi, will relieve the pair of their duties.
