An explosive volcanic eruption on Mars created this rare mineral!

In 2016, the Curiosity rover found a mineral called tridymite in sediments observed inside the Gale crater in which it landed exactly 10 years ago. According to some researchers, this mineral was formed by fractional crystallization in a magmatic reservoir, before being thrown into the air during an explosive eruption to finally fall and sediment …

Mars: we are now certain, the basic ingredients of life were on its surface

Since 2012, the rover Curiosity is conducting investigations on the surface of Mars with the aim of better constraining the climate evolution of the Red Planet and the presence of water liquid in its past, but also to determine whether or not Mars was ever able to support life. If we now know that many …

Curiosity takes inventory of a key ingredient for life on Mars

Mission teams from the Curiosity rover have measured levels of total organic carbon (a key component of molecules of life) in Martian sedimentary rocks for the first time. These samples were taken from the Gale crater which once housed a huge body of water. Organic carbon If the surface of Mars is today inhospitable for …

"Mars will remain uninhabitable, and the Earth, even degraded, will be infinitely more habitable"

“Mars will remain uninhabitable, and the Earth, even degraded, will be infinitely more habitable”

Astrophysicist Sylvia Ekström was invited Thursday in La Matinale to discuss the 250th anniversary of the Geneva Observatory. The researcher notably mentioned the fantasy of man going to live on the planet Mars, an “impossible” scenario, according to her. In 1950 on the ancestor of the RTS – radio Sottens -, when asked whether beings …
