NASA's Perseverance Mars rover just dropped its 10th sample tube, completing a backup depot of material for future return to Earth.

A broken hill, an ancient crater and the human tendency to find faces everywhere may explain the teddy bear on Mars.

This futuristic engine could save lots of propellant on interplanetary journeys, perhaps allowing NASA to explore the solar system more efficiently.

The moon will eclipse Mars on Monday (Jan. 30), and you can watch the event from the comfort of your own home thanks to a livestream from the Griffith Observatory.

The weather station on NASA's Perseverance rover has chronicled the meteorology above Jezero Crater.
