The new measurement is consistent with the idea that gas escaped from the top of the For example, Curiosity's onboard weather station, known as REMS (for Rover Environmental Monitoring Station) has shown that humidity varies from place to place along the robot's route inside Mars' huge Gale Crater. Solar wind and radiation are responsible for stripping the Martian atmosphere, transforming Mars from a planet that could have supported life billions of years ago into a frigid desert world, according to new results from NASA's MAVEN spacecraft. NY 10036. The results show the water vapor consists of more deuterium than that of Earth's water, i.e.
Released on November 5, 2013. Bobak Ferdowsi, Curiosity flight director, shares a special message with students on building robots. Mastcam 34: Shorter Focal-Length Eye of Mast Camera Pair for Mars Rover
MAVEN: Mars Atmospheric Loss. Embed this resource by pasting the following code into your website: "We found arguably the clearest and most robust signature of atmospheric loss on Curiosity used its Sample Analysis at Mars (SAM) instrument to sniff a sample of Martian air and measured the ratio of two different argon isotopes, which are varieties of an element that have different numbers of neutrons in their atomic nuclei. The instrument found that the lighter argon-36 is about four times as common as the heavier argon-38. The first drill holes on Mars by NASA's Curiosity rover are seen in this image taken by the rover on March 29, 2013 at the John Klein rock in the Yellowknife Bay area of Mars' Gale Crater.

NASA's Curiosity Mars rover used the camera on its arm on July 12, 2014, to catch the first images of sparks produced by the rover's laser being shot at a rock on Mars. Deuterium is a heavier version of the hydrogen atom. This self-portrait of NASA's Curiosity Mars rover shows the vehicle at the "Mojave" site, where its drill collected the mission's second taste of Mount Sharp. This map of Mars shows all of the more than 60 landing sites proposed for the Mars Science Laboratory (red dots) and the four final candidate sites (blue dots). NASA engineers take the Curiosity test rover to California's Mojave desert to learn how to drive on Martian sand dunes. The left image is from befo... Mars, which has less gravity than Earth and lacks a strong enough magnetic field to shield its atmosphere from the sun, is slowly losing its atmosphere.

NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has sent back instrument data from the thin upper atmosphere of Mars, which scientists say shows atmospheric loss …

NASA's Mars rover Curiosity drove 6.2 feet (1.9 meters) during the 100th Martian day, or sol, of the mission (Nov. 16, 2012). Mars, which has less gravity than Earth and lacks a strong enough magnetic field to shield its atmosphere from the sun, is slowly losing its atmosphere. As this process occurs, the lighter hydrogen atoms are preferentially lost compared to the heavier deuterium ones. "Curiosity landed inside Gale Crater on the night of Aug. 5, kicking off a two-year surface mission to determine if the area could ever have supported microbial life.Rover scientists have already achieved this goal, announcing last month that an area called Yellowknife Bay was a wet, habitable environment billions of years ago.
