What's up with these weird blue patches on Mars? The red planet seems like it's turning blue. A European probe in orbit around Mars just photographed 2 deep blue patches on the Martian surface, but while they might look like lakes to the untrained eye, don't be deceived. The spots are actually layers of dark, volcanic rock that appear blue in the photo taken by the European Space Agency's Mars Express spacecraft. Winds on Mars blew dark sediment to the areas of the planet. The blue coloring…

What's up with these weird blue patches on Mars?

A spacecraft orbiting Mars photographed two blue patches on the red planet. These lagoon-looking structures are actually just dark sediments.

Here's another one. Martian dark, jagged dunes. Image credit: NASA.

The Syrtis Major Volcanic Province. Acquired by the High Resolution Stereo Camera on ESA’s Mars Express Satellite, this image depicts a detailed region of the Martian Nili Fossae Graben system. This system is an area of great interest to geologists due to the variety of its landscape. The graben system contains numerous troughs, plateaus, impact craters and depressions.

Reull Vallis, the river-like structure, is believed to have formed when running water flowed in the distant martian past, cutting a steep-sided channel through the Promethei Terra Highlands before running on towards the floor of the vast Hellas basin.

This image of a circular depression on the surface of Mars was acquired on Jan. 5, 2015 by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter (MRO). The spacecraft has been orbiting Mars since March 2006 and completed its 40,000th orbit around Mars on Feb. 7, 2015.

The Mars Express orbiter captured this striking view of rugged Martian landscapes extending from a mist-filled Coprates Chasma in the south, to Juventae Chasma and the outflow channels of Maja Valles in the north. Juventae Chasma, the box canyon near the center of the image, is about 100 km wide.

Martian Crater Rich in Opal- The CRISM imaging spectrometer on board the Mars Reconnaissance Orbiter identified the minerals present in this crater south of Baldet Crater. Among them: a form of hydrated silica better known as the gemstone opal. The colors of the landscape don't appear as they would to the human eye, because instead of the usual red, green, and blue components of photographs, this image comes from infrared, red, and blue/green sensors.

The Dotted Dunes of Mars. As spring dawns on the Northern Hemisphere of Mars, dunes of sand near the poles begin to defrost. Thinner regions of ice typically thaw first revealing sand whose darkness soaks in sunlight and accelerates the thaw. The process might involve sandy jets exploding through the thinning ice. By summer, the spots expand to encompass the entire dunes that are then completely thawed and dark. The carbon dioxide and water ice sublime in the thin atmosphere directly to gas.

A NASA spacecraft has discovered glass on the surface of Mars for the first time, a finding that could help in the hunt for past Martian life.

NASA finds glass on Mars, which could help the hunt for alien life

NASA craft finds impact glass on mars that may hold evidence of past life. Jun 2015 NASA's Mars Reconnaissance Orbiter has detected the presence of impact glass in some of the planet's most ancient craters.
