Former U.S. senator Bill Nelson (D-Fla.) was officially and unanimously confirmed by the Senate to be the agency’s new administrator Thursday (April 29). 

President Joe Biden nominated Nelson for the role of new NASA administrator last month. Nelson takes the reins from acting NASA Administrator Steve Jurczyk, who had been leading the agency following the departure of previous administrator Jim Bridenstine. Bridenstine stepped down as NASA chief at the end of the Trump presidency in January 2021.
