The longest organic molecules identified to date on Mars have recently been detected by scientists from the CNRS, together with their colleagues from France, the U.S., Mexico, and Spain. These long carbon chains, containing up to 12 consecutive carbon atoms, could exhibit features similar to the fatty acids produced on Earth by biological activity.

The lack of geological activity and the cold, arid climate on Mars have helped preserve this invaluable organic matter in a clay-rich sample for the past 3.7 billion years. It therefore dates from the period during which life first emerged on Earth. These findings are due to be published on March 24, 2025, in the Proceedings of the National Academy of Sciences.

The discovery was made using SAM, one of the inst...

ESA’s ExoMars Trace Gas Orbiter has detected glowing green oxygen in Mars’ atmosphere—the first time that this emission has been seen around a planet other than Earth.

On Earth, glowing oxygen is produced during polar auroras when energetic electrons from interplanetary space hit the upper atmosphere. This oxygen-driven emission of light gives polar auroras their beautiful and characteristic green hue.

The aurora, however, is just one way...

European-Russian spacecraft were on course for Mars Monday after crucial deep-space manoeuvres in preparation for a daring mission to find evidence of life on the Red Planet. The Trace Gas Orbiter (TGO) mothership despatched the tiny Mars lander called Schiaparelli Sunday on a 3-day trek to the Martian surface in a key phase of the joint ExoMars project. There were nervous moments for ground controllers when TGO, designed to enter Mars’ orbit to analyse its atmosphere for life, stopped sending status updates for about an hour before coming back online.

In the early hours of Monday, the TGO successfully complet...
