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

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

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,

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

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 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.

On 1992, Nasa launched the Mars Observer, aiming to unlock the mysteries of the Red Planet, while in 1977, the first Chicago Marathon was held, ushering in a new era of long-distance running in the Un

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.
