NASA Mars Rover's Weather Data Bolster Case for Brine


Martian weather and soil conditions that NASA's Curiosity rover has measured, together with a type of salt found in Martian soil, could put liquid brine in the soil at night.

Perchlorate identified in Martian soil by the Curiosity mission, and previously by NASA's Phoenix Mars Lander mission, has properties of absorbing water vapor from the atmosphere and lowering the freezing temperature of water. This has been proposed for years as a mechanism for possible existence of transient liquid brines at higher latitudes on modern Mars, despite the Red Planet's cold and dry conditions.

Mars Rover's Laser-Zapping Instrument Gets Sharper Vision

Tests on Mars have confirmed success of a repair to the autonomous focusing capability of the Chemistry and Camera (ChemCam) instrument on NASA's Curiosity Mars rover.

This instrument provides information about the chemical composition of targets by zapping them with laser pulses and taking spectrometer readings of the induced sparks. It also takes detailed images through a telescope.

Work by the instrument's team members at Los Alamos National Laboratory in New Mexico and in France has yielded an alternative auto-focus method following loss of use of a small laser that served for focusing the instrument during Curiosity's first two years on Mars.

This May 15, 2015, image from the Chemistry and Camera (ChemCam) instrument on NASA's Curiosity Mars rover shows detailed texture of a rock target called "Yellowjacket" on Mars' Mount Sharp. This was the first rock target for ChemCam after checkout of restored capability for autonomous focusing.

Mars Rover Finds Rocks Suggesting Red Planet Had Continental Crust

Some unusually light-colored rocks on Mars discovered by NASA's Curiosity rover are surprisingly similar to granitic continental crust rocks of Earth, the first evidence of a potential "continental crust" on Mars, scientists say.

Mars has been thought of as mostly a basaltic planet, covered with dark, relatively dense igneous rocks like those making up the Earth's crust below our oceans.


A geologic find by the Curiosity rover suggests Mars in its distant past may have been much more like the Earth, researchers say. Early Mars may have had tectonic plates that formed continents, they suggest.

Might be, 'cause of the lack of magnetic field...so the solar winds blown off all the atmosphere from Mars... :/

We won't know...until we make a time-trip!
