After a long career as a politician from Florida, former astronaut Bill Nelson has served as NASA's administrator for the last three and a half years. He intends to resign from this position in about two weeks when President Joe Biden ends his term in the White House. Several significant events have happened under Nelson's watch at NASA, including the long-delayed but ultimately successful launch of the James Webb Space Telescope, the flight of the first Artemis mission, and the momentous decision to fly Boeing's Starliner spacecraft back to Earth without crew aboard.
