Clays discovered in 2005 by the Mars Reconnaissance Orbiter probe in the southern hemisphere of Mars had been considered, until now, as proof that 4,000 million years ago the red planet harbored liquid water and had conditions suitable for life. But a study published in the journal Nature Geoscience reveals that these clays could have a volcanic origin and that the Martian environment of that time was by no means the most suitable for life.
The Curiosity rover, the most advanced rover that NASA has sent to Mars so far, has successfully completed its landing on the surface of the red planet, where it arrived at 05.31 GMT (07.31 Spanish time), that is, a little more late than planned. The journey has lasted 36 weeks, and has traveled a distance of 248 million kilometers.
ESA's Mars Express spacecraft celebrates eight years in space with a new vision of the ice in the south polar region of Mars during the spring of the red planet. The poles are closely linked to the Martian climate and constantly change with the seasons. Their study is an important scientific objective of the mission.
Last week, the Tinto riverbed, in the province of Huelva, in southern Spain, hosted a test campaign in which an ESA rover, a prototype spacesuit and a medical monitoring system similar to those were tested. those that will one day be used in manned exploration of Mars.
The Mars Odyssey probe this week broke the record for staying on Mars by overcoming more than 3,340 working days on the red planet, since it entered orbit on October 24, 2001. In this way Odyssey surpassed its predecessor Surveyor, which was in orbit from September 11, 1997 to November 2, 2006.
