While the news of very large organic molecules Found on the planet Mars still sounds, the Rover Perseverance of NASA has just made a discovery, this March 11, 2025, which leaves the scientific teams to say the least perplexed.

In the Jezero crater he has been walking since 2021, the big robot of the United States space agency did not come across a bone-we would have loved as a sign of fossilized life! -, but on a rock with truly atypical characteristics which denotes on the ground. This big pebble was baptized St Pauls Bay and Perseverance identified it after two weeks spent on the slopes of the Witch Haze Hill, as we can see in this image:

There are two possible explanations for this geological oddity of about 20 cm containing hundreds of spherules, these small characteristic rounded formations, some of which are pierced as by a pin bite. The first explanation involves groundwater infiltrated into the rock and leading to these concretions.

The second is more explosive: these spherules also resemble the rapid cooling of rock droplets after a volcanic eruption or a meteoritic impact. Besides, the Jezero site is an impact crater dated approximately 3.7 billion years.

“Each of these training mechanisms would have very different implications for the evolution of these rocks, so that the team works hard to determine their context and their origin”said the mission team in the press release according to this strange discovery.

Last July, it was A “leopard” rock Who had caused a sensation, this one still being at present the best index of a possible life spent on the red planet …
