The name of Mary Jackson, NASA's first African American female engineer and one of the barrier-breaking inspirations for the book "Hidden Figures," will officially adorn the space agency's Washington, DC, headquarters Friday.

The Perseverance rover has had a chance to settle in on Mars since landing last Thursday, so it's doing what every new resident does these days -- sending back photos of its new home.

The NASA Perseverance rover safely landed on Mars after its 292.5 million-mile journey from Earth, the agency confirmed at 3:55 p.m. ET Thursday. The rover landed itself flawlessly, according to the mission's team.
