NASA scientists were baffled after uncovering a rock on Mars that didn’t belong there — with a composition pointing to potentially interstellar origins. “This rock was identified as a target of interest,” the space agency wrote in a recent blog post detailing the potentially intergalactic gravelstone.

NASA's Perseverance Mars Rover strikes gold, discovers a trove of ancient rocks on Jezero Crater

A memo sent by the Smithsonian said transporting Discovery could swell in price and result in irreparable damage to the space shuttle.

NASA's Perseverance rover found a peculiar rock on Mars. Its composition suggests it may have originated from beyond our solar system. The rock, named Phippsaksla, stands out due to its unique shape and high iron and nickel content.

NASA’s Perseverance Mars rover has made another strange discovery. While investigating the Vernodden area of Jezero Crater – the crater where the rover first landed on the Red Planet in February 2021 – it found an unusually shaped rock that is not meant to be Where it may have come from is anyone’s guess,

It's been five years since NASA's Perseverance rover touched down on Mars, sending back images and data that have revealed some of the red planet’s oddest and most peculiar features. Now, the rover has stumbled across an unusually shaped rock about 80 centimetres across (about 31 inches) called "Phippsaksla.

Not yet proof, but potential proof of biosignature of life on Mars, this is the closest NASA has been to discovering a real trace of life so far on Mars said Nicky Fox, deputy administrator of NASA's Science Mission Directorate.

Lettuce grown in space loses calcium, raising concerns about critical nutritional risks for future missions to Mars.

A rock that is described as "unusually shaped" and "not meant to be on the surface of Mars" has nevertheless made its way to the planet.

"Over time, the rays will darken to the shade of the surrounding regolith as the material is exposed to space weathering," the LROC statement reads. It's also notably small, as the team refers to it as a "freckle" on the moon.
