There’s a new NASA chief in town. Today (May 3), former U.S. senator Bill Nelson (D-Fla.), 78, was sworn in as the agency’s 14th administrator. 

Vice President Kamala Harris, who was recently confirmed as the chair of the National Space Council (as is tradition with vice presidents), swore Nelson in this morning in a ceremony that took place at the Eisenhower Executive Office Building near the White House in Washington, D.C.. Nelson is taking over the NASA leader role from former administrator Jim Bridenstine, who stepped down from the post in January. Steve Jurczyk has temporarily filled the role of NASA’s acting administrator in the time since.
