Did 40-year-old Viking experiment discover life on Mars?

(Phys.org)—In 1976, two Viking landers became the first US spacecraft from Earth to touch down on Mars. They took the first high-resolution images of the planet, surveyed the planet's geographical features, and analyzed ...

Europe, Russia embark on search for life on Mars

Europe and Russia are set to launch an unmanned spacecraft Monday to smell Mars' atmosphere for gassy evidence that life once existed on the Red Planet, or may do so still.

Viking landers did detect organics on Mars

(PhysOrg.com) -- In 1976 the NASA Viking landers took samples of soil on Mars and tested them for signs of organic carbon. A reinterpretation of the results now suggests the samples did contain organic compounds, but the ...

Solar eclipse measured on Mars, affects interior

NASA's InSight mission provides data from the surface of Mars. Its seismometer, equipped with electronics built at ETH Zurich, not only records marsquakes, but unexpectedly reacts to solar eclipses as well. When the Martian ...

NASA's InSight detects two sizable quakes on Mars

NASA's InSight lander has detected two strong, clear quakes originating in a location of Mars called Cerberus Fossae—the same place where two strong quakes were seen earlier in the mission. The new quakes have magnitudes ...

NASA's next Mars rover progresses toward 2020 launch

After an extensive review process and passing a major development milestone, NASA is ready to proceed with final design and construction of its next Mars rover, currently targeted to launch in summer of 2020 and arrive on ...

Liquid saltwater is likely present on Mars, new analysis shows

(PhysOrg.com) -- Salty, liquid water has been detected on a leg of the Mars Phoenix Lander and therefore could be present at other locations on the planet, according to analysis by a group of mission scientists led by a University ...

Search for life on Mars could get water-enhanced boost

A new experiment designed to detect amino acids on Mars, in spite of the reactive perchlorate in the Martian soil that typically breaks organic compounds down, could fly on a future mission to Mars to help in the search for ...

New views show old NASA Mars landers

(PhysOrg.com) -- The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter recorded a scene on Jan. 29, 2012, that includes the first color image from orbit showing the three-petal ...
