The discovery supports the notion that ancient Mars may have been hospitable for life. [99] [100] [101] It is suspected that all nitrate on Mars is a relic, with no modern contribution. [102] Nitrate abundance ranges from non-detection to 681 ± 304 mg/kg in the samples examined until late 2017. [102]
A mineral grain from a meteorite preserved evidence that water was present on Mars 4.45 billion years ago, and it may have created hot springs habitable for life.
Researchers have uncovered what may be the oldest direct evidence of hot water activity on Mars, suggesting the red planet could have supported life billions of years ago.. Scientists at Australia ...
“Is there life on Mars” is a question that has vexed astrobiologists and David Bowie alike. While the latter imagined some macabre collection of arachnids on the Red Planet, NASA scientists ...
These springs may be good places to look for evidence of past life because hot springs can preserve evidence of life forms for a long time. Location is Oxia Palus quadrangle. The Mars Reconnaissance Orbiter's HiRISE instrument has taken many images that strongly suggest that Mars has had a rich history of water-related processes. Many features ...
On March 2, 2004, NASA announced that "Opportunity has landed in an area of Mars where liquid water once drenched the surface". Associate administrator Ed Weiler told reporters that the area "would have been good habitable environment", although no traces of life have been found. Larger grains suggest the presence of fluid.
This is the "best evidence yet" that Mars still has liquid water in addition to frozen water at its poles, according to the University of California, San Diego's Scripps Institution of ...
In January 2004, the NASA twin Mars Exploration Rovers named Spirit (MER-A) and Opportunity (MER-B) landed on the surface of Mars. Both have met and exceeded all their science objectives. Among the most significant scientific returns has been conclusive evidence that liquid water existed at some time in the past at both landing sites.
