Mars lander on course for Monday touchdown
After a six-month voyage from Earth, NASA’s InSight Mars lander, streaking through space at at some 12,300 mph, will slam into the thin martian atmosphere Monday afternoon to begin a nail-biting six-and-a-half-minute descent to the surface, kicking off a billion-dollar mission to probe the red planet’s hidden interior.
