Twelve thrusters will slow InSight to the surface of Mars.

PASADENA, CALIFORNIA—A boring spot on Mars is about to get real interesting. Later today, at 11:54 a.m. PST, NASA’s $814 million InSight spacecraft will attempt to land on a flat lava plain near the martian equator. The mission will be NASA’s first landing on the Red Planet since the Curiosity rover in 2012.
