Astronauts Butch Wilmore and Suni Williams are conducting a spacewalk outside the International Space Station to remove degraded hardware and swab for microorganisms.

Starliner co-pilot Sunita Williams is now the world's most experienced female spacewalker, moving up to No. 4 overall.

President Donald Trump took to social media this week to announce he had directed SpaceX CEO Elon Musk to “go get” two NASA astronauts who have been on a protracted stay at the International Space Station after their Boeing Starliner mission, which launched in June and was expected to last about eight days, ran into multiple technical issues.

NASA astronauts Suni Williams and Butch Wilmore completed a spacewalk Thursday while awaiting their delayed return to Earth. Williams set a new spacewalking record for female astronauts during the mission.

President Donald Trump said Tuesday night he had asked Elon Musk's SpaceX to return two NASA astronauts from the International Space Station, who were already scheduled to fly back on a SpaceX capsule in March.
