Hasta La Gadget!

Curiosity may have spent a while limbering up for the mission ahead, but now it’s found evidence of an ancient streambed on Mars that once had “vigorous” water flow. Photos of two rock outcroppings taken by the rover’s mast camera between the north rim of Gale Crater and the foot of Mount Sharp reveal gravel embedded into a layer of conglomerate rock. The shape of the small stones indicate to NASA JPL scientists that they were previously moved, and their size (think from grains of sand to golf balls) are a telltale sign that water did the work instead of wind. Evidence of H2O on Mars has been spotted before, but this is the first direct look at the composition of riverbeds NASA has observed from above.

According to Curiosity science co-investigator William Dietrich, it’s estimated that water flowed at the site anywhere from thousands to millions of years ago, moved at a clip of roughly 3 feet per second and was somewhere between ankle and hip deep. “A long-flowing stream can be a habitable environment,” Mars Science Laboratory Project Scientist John Grotzinger said. “It is not our top choice as an environment for preservation of organics, though. We’re still going to Mount Sharp, but this is insurance that we have already found our first potentially habitable environment.”

Now that Curiosity has survived its thrill-a-minute landing and passed an upgrade and physical with (nearly) flying colors, the rover is off to earn its $2 billion keep. The buggy got off to a good start, driving 52 feet towards its first science site “beautifully, just as our rover planners designed it,” according to NASA. The destination, Glenelg, is 1,500 feet away from the now-familiar Bradbury Landing where it first set down, which is pretty far for a rover that treks along at about a tenth of a mile per hour. On top of that, its minders have some stops in mind to test instruments — meaning it’ll arrive there in about two weeks. Once at Glenelg, Curiousity will scope the unusual geology of the region, though its principal destination for science is Mount Sharp, a relatively vast six miles away. Don’t worry about it running out of gas, though — it’s nuclear power supply will last a full Martian year, or 687 earth days.

This isn’t even a joke! Serious musician Will.i.am is premiering a new song tomorrow. On Mars. Broadcast through the Curiosity rover. And the name of said song, which also just for the record is not actually a joke, is “Reach for the Stars.” More »

The surface of Mars? Psh… been there. With the Curiosity stage well under way, our exploration of the Red Planet is about to take a dive beneath the dust. Interior Exploration using Seismic Investigations, Geodesy and Heat Transport — InSight, for short — was just confirmed as a new NASA mission, with the space agency set to launch in March of 2016. Based on the Phoenix lander, the craft is tasked with giving us a peek beneath the planet’s surface, armed with tools that include a geodetic instrument from the Jet Propulsion Laboratory, which will be used to calculate Mars’ rotation axis, a seismic wave sensor and a subsurface heat probe, to measure the planet’s internal temperature. The program has a $425 million budget — a bit shy of the $2.5 billion allocated for Curiosity — not including the costly launch vehicle. NASA Administrator Charles Bolden said that InSight will help pave the way for future human missions to Mars, and represents just one of the related projects to come. Hit up the source link below for a closer look at JPL’s latest endeavor.

Intrepid 6-wheeler Curiosity perhaps protested too much when it tweeted “Yes, I’ve got a laser beam attached to my head. I’m not ill tempered; I zapped a rock for science.” NASA turned the rover‘s high-powered laser loose with 30 pulses of a million watts each, reducing a thin layer of the chosen stone, dubbed N165 “Coronation,” to plasma. The resulting spectrum was then analyzed by the on-board “ChemCam” to determine its composition, and the US/French team who developed the system said it’s working even better on Mars than it did on terra firma. The results are now being studied, but if we had a laser beam on another planet, we’d be firing it all over the place — in the name of “science,” of course.
