Home Photography of the Week: The Curiosity Rover is One Salty Dog

NASA’s Curiosity rover touched down on Mars in August 2012, and it’s been cruising around, shooting lasers at rocks, drilling into the ground, and performing science experiments ever since.

NASA’s Curiosity rover touched down on Mars in August 2012, and it’s been cruising spherical, shooting lasers at rocks, drilling into the bottom, and performing science experiments ever since. Real closing week, recordsdata came out that Curiosity had found something salty. The rover is driving all over Gale Crater, an frail Martian lake bed that used to be as soon as stuffed with water, and has found sulfate salts.

Scientists mediate this is seemingly due to a extremely dry interval when water evaporated, leaving the salts within the wait on of. Our dangle Earth stays moist as a consequence of now we maintain an atmosphere and a magnetic field, which keeps our planet watery and healthy so we can very without problems continue to exist. However the narrative for Mars is a little bit extra complex. Billions of years ago, Mars had an atmosphere but it’s progressively had a moderately small magnetic field, so the represent voltaic winds from the Solar stripped the atmosphere away over time—leaving it the dry, arid planet now we maintain grown to admire.

This week we’re going to rove spherical on Mars alongside the finest, baddest, robotic on the red planet.

NASA tends to name the rocks that Curiosity finds alongside its plug. Now meet “Frail Soaker.” This slab is 3 feet prolonged and has positively viewed some things over the past 3.5 billion years. The crackling enact is as a consequence of of puddles pooling over this rock and drying out, and pooling as soon as more and drying out—a path of that repeated itself for aeons, leaving within the wait on of this textured witness.Photograph: NASA/JPL-Caltech/MSSS
This team of rocks is known as Squid Cove, and admire Frail Soaker, it has viewed a entire lot of moist and dry spells. Most of what has created these formations is sediment assemble up over billions of years, and Martian geologists explore to infer the water evaporation cycle from the patterns and materials they watch. Photograph: NASA/JPL-Caltech/MSSS
The Mars Reconnaissance Orbiter is a workhorse satellite that has taken some of one of the vital magnificent images of Mars ever. These rolling blue hills and dunes are the bottom of Gale Crater. In these HiRise digicam images, the blue represents the form of self-discipline fabric on the bottom, which in this case would possibly maybe be extremely beautiful sand. These false colors are created by the HiRise digicam processing—murky would possibly maybe thunder salty water, as an illustration.Photograph: NASA/JPL-Caltech/University of Arizona
