Mars rover Perseverance finds interesting rock that may have harbored microbial life billions of years ago
Analysis by instruments on board the rover shows that the rock has qualities that meet the definition of a possible indicator of ancient life. The rock contains chemical signatures and structures that could have been formed by life billions of years ago, when there was flowing water in the area the rover was exploring. The science team is considering other explanations for the observed features, and further research will be needed to determine whether ancient life is a valid explanation.
A whole field of sulfur rocks, the latest discoveries on Mars and amazing photos
As the rover ascends, it moves along the Martian timeline, allowing scientists to study how Mars evolved from a planet that was more like Earth in the distant past, with a warmer climate and abundant water, to the icy desert it is today. The amount of frost on Mars’ equatorial volcanoes represents about 150,000 tons of water exchanged between the surface and the atmosphere every day during the cold season, equivalent to about 60 Olympic swimming pools. NASA’s Curiosity rover has discovered crystals of pure sulfur on Mars.
NASA’s Perseverance rover confirms the presence of an ancient dry lake on Mars
NASA’s Perseverance rover has confirmed the presence of an ancient lake on Mars that could hold the key to ancient life. Evidence of ancient lacustrine sediments at the base of Jezero Crater on Mars offers new hope for detecting traces of life in samples collected by NASA’s Perseverance rover.
The historic journey of Ingenuity, the first Earth-based helicopter on Mars, has come to an end
Originally designed as a technology demonstration to perform up to five experimental test flights over 30 days, the first off-planet vehicle operated on Mars for nearly three years, completed 72 flights, and flew more than 14 times farther than planned while recording more than two hours total flight time.
Researchers are studying layers of water ice on Mars
Mars appears to be a dry world now, but there are plenty of signs on the planet’s surface that there was once plenty of water, including dry river beds, ancient ocean and lake beds, and valleys carved by water. Significant reserves of water ice have also been discovered on Mars, such as huge polar ice caps, buried glaciers closer to the equator, and near-surface ice permeated by the Martian soil.
Mars has its own aurora
A Mars probe has discovered that the Red Planet’s atmosphere glows green at night. Scientists have observed the night glow of Mars in the visible light spectrum for the first time, the European Space Agency reports.
Mars exploration: China gains insights from its first rover
The team of China’s first Mars rover, Zhurong, published the results of an analysis of data collected on Utopia Planitia in the journal Nature Geoscience.
