NASA's InSight spacecraft lands on Mars to explore planet's interior

A NASA spacecraft has landed on Mars to explore the planet's interior.

Flight controllers announced that the spacecraft InSight touched down Monday, after a perilous supersonic descent through the red Martian skies. Confirmation came via radio signals that took more than eight minutes to cross the nearly 100 million miles between Mars and Earth.

There was no immediate word on whether the lander was in good working order. NASA satellites around Mars will provide updates.

It is NASA's eighth successful Mars landing since the 1976 Vikings. The thee-legged, one-armed InSight will operate from the same spot for the next two years. It landed less than 400 miles from NASA's Curiosity rover, which until Monday was the youngest working robot in town.
