Scientists working on NASA’s Mars Science Laboratory mission have been somewhat sparing until now when describing exactly how the rocks drilled, gobbled and cooked by the Curiosity rover paint a picture of a life-friendly environment.Well, no more.Iran has committed to halting certain levels of enrichment and neutralizing part of its stockpiles Best Cool Boy Kayak Trolley for Sale
In a suite of findings announced Monday, the scientists are painting a vivid picture of Gale Crater: filled with a modest lake of water, rich in the chemical ingredients for life, theoretically able to support a whole Martian biosphere based on Earth-like microbes called chemolithoautotrophs.“Ancient Mars was more habitable than we imagined,” Caltech geologist John Grotzinger, the mission’s lead scientist, said of the findings described in six papers in the journal Science and at the American Geophysical Union meeting in San Francisco.If microbial life ever developed,their speed and operate below their optimum combustion ER Collets
. it potentially had thousands to tens of millions of years to take hold, the scientists said. That watery window of opportunity seems to exist around 3.6 billion years ago, about the same age of the earliest fossils of microbial life found on Earth.Curiosity landed in Gale Crater on Aug. 5, 2012, with the goal to search for life-friendly environments at Mt. Sharp, the 3-mile-high mound in the crater’s center whose diverse, clay-rich layers could hold a detailed history of many different habitats hosted in Gale over the eons.But rather than head straight to Mt. Sharp, the rover took an extended detour to an intriguing spot called Yellowknife Bay, drilling into two rocks, named John Klein and Cumberland. The two rocks have turned up a smorgasbord of elements needed for life, including carbon, hydrogen, oxygen, sulfur, nitrogen and phosphorus.But the rover has thus far been unable to find any organic carbon, which is typically in a hydrogen-loaded molecule that’s accessible to most living things on Earth. That’s because part of its inner lab,The town produces about 8 percent of its electricity with aaerial working platform
system installed several years ago the Sample Analysis at Mars suite, works by cooking soil samples to analyze the gases they form -- and this essentially destroys some crucial information.But here’s the thing: Either way, life could still exist with or without organic carbon. In a past watery environment, chemolithoautotrophs would have done just fine with the ingredients already found on Mars. On Earth, these microbes tend to live in caves and can survive underground. They feed on chemicals in rock, and they’re autotrophs -- they make their own energy. On Earth, autotrophs like plants help provide the foundation of a whole biosphere of other species of living things.
