NASA’s Mars Rover Opportunity is working in an ancient valley on the edge of Endeavour Endeavour’s rim called “Perseverance Valley” examining rocks and driving around the area to carry out a survey of the place. According to plans, once these tasks are completed Opportunity will go down to the lower part of the valley but the maneuver will have to be even more cautious than expected due to a problem encountered in one of the wheels’ steering system.

An article published in the journal “Earth and Planetary Science Letters” describes a study of the first samples taken in the lower layers of Mount Sharp on Mars by NASA’s Mars Rover Curiosity. A team of scientists in the ARES Division at NASA’s Johnson Space Center compared the minerals found in the first samples analyzed, which show the different environmental conditions that existed over time.
An article published in the journal “Geophysical Research Letters” describes a research on silica halos discovered in the lower areas of the northern slopes of Aeolis Mons in the Gale Crater on Mars. A team of researchers led by Jens Frydenvang used the information gathered by NASA’s Mars Rover Curiosity to try to figure out for how long there was liquid water, concluding that the needed conditions lasted longer than expected.
NASA’s Mars Rover Opportunity has begun its scientific work in yet another Mars area to be explored during a mission that has been going on for over 13 Earth’s years. This mission was extended for the tenth time in 2016 and now its goal is to study “Perseverance Valley”, an ancient valley on the inner slope of the Endeavor crater’s rim to figure out how it formed.
An article published in the journal “Science” describes a research on the atmosphere of the planet Mars that indicates the Sun’s wind and radiation as the principal culprits of the fact that today that atmosphere is so thin. A team led by Bruce Jakosky, principal investigator of NASA’s MAVEN space probe’s mission, examined the measurements of the existing gases estimating for example that 65% of argon present origininally got lost in space. This research confirms the one published in November 2015.
