Curiosity Mars Rover

Martian rock samples collected by NASA's Curiosity Mars rover show signs of key ingredients of life as we know it on Earth.

The Curiosity rover might be spotting signs of the Martian climate drying up in ancient times.

A long-running NASA rover imaged twisted Red Planet rock pillars.

The strange door-like feature discovered in a martian cliff earlier this month is perfectly natural but provides a "doorway into the past", said NASA.

NASA's Curiosity Mars rover unexpectedly changed its course up Mount Sharp to avoid hazardous "gator-back" terrain.

A new image taken by the Curiosity rover reveals a tiny, flower-like mineral deposit less than half an inch wide on the Martian surface.

The clouds were so faint that NASA employed special imaging techniques to spot them.

NASA's Curiosity rover has left plenty of marks on Mars over the past nine-plus years, and the Red Planet is returning the favor.

Daytime temperatures have climbed above freezing during more than half of Curiosity's days on Mars.

NASA's Curiosity rover has found some interesting organic compounds that may be signs of ancient Mars life, but much more work is needed to vet that hypothesis.
