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

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

Has NASA's Perseverance rover at long last found evidence that life did indeed once exist on Mars? Here's what we know.

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.

On Monday, the space agency announced the 10 people chosen for its 2025 astronaut candidate class, selected from over 8,000 applicants across the U.S. That’s an acceptance rate of about 0.125%, making the odds far more daunting than Harvard’s 4% admission rate.

Potential signs of microbial life were found in a rock sample collected by the rover in 2024 from an ancient dry riverbed on Mars' Jezero Crater -- an area of rocky outcrops on the edges the Neretva Vallis, a river valley carved by water rushing to the canyon billions of years ago, NASA officials announced in a press conference on Wednesday.

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.
