Mars methane surge spotted from space

The methane spike was first measured by Nasa's Curiosity rover on the surface; now it has been confirmed by the Mars Express orbiter. The nature and extent of methane in the Martian atmosphere is intensely debated. The gas is of interest because terrestrial methane can be made by life forms, as well as geological processes. Methane is only supposed to have a very short lifetime in the Martian atmosphere, so detecting it there means it must have been released very recently. *****Martian eclipse by Phobos: If you take the 9 frames roughly in the middle and animate them - you get this.... the bit of each file name before EDR is the time in seconds - so these are about 8 seconds apart....80 or so seconds in this gif.

Fun space fact: There is a volcano on #Mars, called Olympus Mons, that is the size of #France. It's the largest known volcano in the Solar System. Source. Ancient Mars could have supported sub-surface biosphere. It’s now accepted that Mars once was a warmer, wetter world, with organic compounds and liquid water on its surface.

Ancient Mars could have supported sub-surface biosphere

New research shows the red planet also could have supported microorganisms below the surface for hundreds of millions of years. “We showed, based on basic physics and chemistry calculations, that the ancient Martian subsurface likely had enough dissolved hydrogen to power a global subsurface biosphere,” said Jesse Tarnas, a Brown University graduate student and lead author of a study in Earth and Planetary Science Letters. “Conditions in this habitable zone would have been similar to places on Earth where underground life exists.” On Earth, microorganisms in subsurface lithotrophic microbial ecosystems – SLiMEs – can thrive in the absence of sunlight by stripping electrons off dissolved molecular hydrogen. “The question then becomes: What was the nature of that subsurface life, if it existed, and where did it get its energy?” *****360 interactive of Mars: Curiosity Surveys a Mystery Under Dusty Skies.

Put simply, nobody would have been surprised if the planet had always been an arid dead world, small and far from the Sun. But it once had rivers and seas, possibly. Giovanni Schiaparelli was the first to map Mars in detail. He wrote about the planet's 'canali,' which was misleadingly translated into English as "channels" (rather than "canals. Can you guess what planet this globe depicts? @AGSLib… Theconversation. The search for life on Mars has taken a step forward with the NASA Curiosity rover’s discovery of organic matter on the bottom of what was once a lake.

It may once have been part of an alien life form or it might have a non-biological origin – either way this carbon would have provided a food source for any organic living thing in the vicinity. The discovery adds extra intrigue to NASA’s search for extra-terrestrial life forms themselves. When hunting remotely with one car-sized machine, the question is where best to focus your efforts. It makes sense to look for the same types of places we expect to find fossilised microorganisms on Earth. This is complicated by the fact that these fossils are measured in microns – mere millionths of a metre. The Curiosity rover looks for certain sedimentary rocks deposited near water, as it did for the latest discovery. Mono Lake Before our visit, geologists were essentially divided about these chimneys. We went to Mono Lake to find out who was right. In 1949, the rocket pioneer Wernher von Braun wrote a novel about a manned mission to Mars, in which the leader of the Martian government is called ‘Elon’.

Earth is the bright point of light a little left of the image’s center and our moon can be seen just below Earth. Curiosity, which landed on the red planet on August 6, 2013, is the largest and most advanced rover ever sent to Mars. It studies the geology of its surroundings and has found evidence of a past environment well-suited to support microbial life. Researchers used the left-eye camera of Curiosity's Mast Camera (Mastcam) to capture this scene about 80 minutes after sunset on the 529th Martian day, or sol, of the rover's work on Mars (January 31, 2014). The image has been processed to remove cosmic-ray effects. This picture adds to our collection of photos of planet Earth from afar, giving a unique perspective to our place in the cosmos.

This major health risk is stopping us travelling to Mars

China has said it hopes to send people there between 2020 and 2030, and even Russia is floating plans to put boots on the red planet. Meanwhile, SpaceX founder Elon Musk is trying to cut the cost of spaceflight enough to start establishing a permanent Martian colony of 1 million people as soon as possible. But if a study of radiation exposure in mice has any bearing on humans, going to Mars may be much more dangerous than anyone expected. The root problem is cosmic rays, as detailed in a May 2017 Nature study and highlighted by a recent Business Insider video. The Danger of Cosmic Rays Cosmic rays are high-energy atomic and subatomic particles that get blasted out from exploding stars, black holes, and other powerful sources in space. Researchers know that astronauts receive much higher radiation exposure than those of us who remain on Earth, since the planet’s atmosphere absorbs a lot of that harmful energy.
