NASA's Curiosity rover successfully drilled a 2-inch-deep hole in a target called "Duluth" on May 20. It was the first rock sample captured by the drill since October 2016. This image was taken by ...

Aaron Yazzie and others explain how, by scooping dirt and drilling rocks, rovers are digging deeper into the mysteries of Mars.

This sinuous raised ridge is thought to be an inverted stream channel.  These are formerly low-lying streambeds that became elevated because the original depression is filled with materials (such a...

A close-up of the rock, nicknamed “Rochette,” that the Perseverance science team will examine in order to determine whether to take a rock core sample from it.

This stereo view from NASA's Mars Exploration Rover Opportunity shows "Lunokhod 2 Crater," which lies south of "Solander Point" on the west rim of Endeavour Crater. Lunokhod 2 Crater is approximate...

The Earth "rings" whenever earthquakes strike, just as vibrations moving through a bell creates a ringing sound. The InSight mission will see if tremors cause Mars to chime in with its own planetar...

This is an artist's model of an early Mars - billions of years ago - which may have had oceans and a thicker atmosphere.

Missions to outer space have come a long way since the days of Cold War competition. Farah Alibay finds that building relationships is a big part of building spacecraft.
