Learn why scientists are cautiously optimistic about the potential biosignatures found in the Sapphire Canyon rock sample.

Curiosity is exploring Mars’ boxwork terrain, where ridges and hollows may have formed from cementation and erosion. The rover has been documenting rock textures and chemistry, comparing smoother ridge rocks with nodular hollow-edge rocks.

Imelda Muller, who graduated from Taconic Hills High School, is one of 10 people in NASA's latest astronaut class.

Rovers explore distant planets for decades, where humans can't yet go. NASA sends signals from Earth to update the rovers and keep them running.

NASA scientists say a rock sample collected by the Perseverance rover in Jezero Crater may contain the strongest signs yet of ancient microbial life on Mars, though more analysis is needed before drawing firm conclusions.

NASA has discovered signs of life on Mars in the form of organic carbon, sulfur, rust, and phosphorous in a canyon, and new research from the University of Texas at Austin suggests that an atmosphere may have formed billions of years ago,

NASA officials say its Mars-bound ESCAPADE spacecraft is back in Florida and is being prepped for its scheduled launch this fall.
