Doctors fear that the only drug approved to prevent preterm birth, the nation's leading cause of infant mortality and disability, will no longer be available to expectant mothers.

As thousands of anti-abortion rights activists prepared to march in Washington, D.C., on Friday, President Trump was there to rally his base.

At six years old, Jerry Morrison is already shooting for the stars.

"I want to live on another planet," Jerry told his uncle, Joey Jefferson, at StoryCorps in November. "There's so much sights to see: nebulas, hot Jupiters and supernova remnants. They look so beautiful."

Jefferson, 29, also fell in love with space at an early age. It started with a wind-up space shuttle toy his mother gave him when he was a kid. Today he's a mission operations engineer at NASA's Jet Propulsion Lab, where he commanded the Spitzer Space Telescope and the Cassini spacecraft to Saturn.
