Two astronauts who had been stranded on the International Space Station since last summer have finally returned to Earth after their initial week-long mission went awry. Sunita “Suni” Williams and Barry “Butch” Wilmore were stuck in space for nine months longer than their original mission.

Butch Wilmore and Suni Williams have nearly half a century of combined experience as astronauts. But this is just their third time in space. Ms. Williams was born in Ohio but grew up in Massachusetts. She was a test pilot in the U.S. Navy and has spent more than 3,000 hours flying 30 different aircraft. She was selected as a NASA astronaut in 1998.
