U.S. President Joe Biden gave NASA’s acting administrator warm congratulations for the successful landing of the life-seeking Perseverance rover on Mars Thursday (Feb. 18).

“Hey Steve, congratulations man,” said Biden in a call from the Oval Office in Washington, D.C., backdropped by numerous pictures and a statue of American labor leader César Chávez. His call was posted on the White House YouTube channel Saturday (Feb. 20).
