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.

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

The candidates have to do two years of training before they're eligible for flight assignments supporting future missions to low Earth orbit, the Moon, and Mars.

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,

A swarm of spherical rovers, blown by the wind like tumbleweeds, could enable large-scale and low-cost exploration of the Martian surface, according to results presented at the Joint Meeting of the Europlanet Science Congress and the Division for Planetary Sciences (EPSC-DPS) 2025.

But the claim that NASA announced found life on Mars was false. NASA announced it found promising evidence of potential ancient life on the planet, but more research was needed before scientists could comfortably declare it was definitive evidence of life.

NASA's Mars Reconnaissance Orbiter (MRO) has captured several images of the Insight lander on the Red Planet between 2018 and 2024. See a time-lapse of the imagery here. Credit: NASA/JPL-Caltech/Unive
