A SpaceX capsule has arrived at the International Space Station, delivering the replacements for NASA's two stuck astronauts.

Reaching orbit from NASA’s Kennedy Space Center, the newest crew includes NASA’s Anne McClain and Nichole Ayers, both military pilots; and Japan’s Takuya Onishi and Russia’s Kirill Peskov, both former airline pilots. They will spend the next six months at the space station, considered the normal stint, after springing Wilmore and Williams free.

During a second attempt, SpaceX successfully launched a mission on March 14 to replace two NASA astronauts who have been stuck on the International Space Station for nine months.
