Subdeacon Joe Posted January 1, 2018 Share Posted January 1, 2018 Amazing stuff.https://www.digitaltrends.com/photography/best-space-photos/?utm_source=f1&utm_medium=cpc&utm_campaign=spacephotos3&utm_content=v%23%2F1#/1 Alien terrain Earlier this year, the Mars Reconnaissance Orbiter captured this image of a portion of the Hellas Planitia -- the largest visible impact basin in our solar system. The formation is more than 1,200 miles in diameter and deeper than the Grand Canyon along certain stretches. However, what is truly mesmerizing about this particular expansive dune field depicted above are the strange, extensive network of winding clefts and the cause of these seemingly meandering markings is still largely unknown. During the Martian winter, higher latitude surfaces are covered with frost and NASA postulates that these "linear gullies" are formed as this dry ice breaks apart and slowly sift downward along these warm slopes. The space agency is currently testing a prototype "igloo" habitat that could utilize subsurface water ice to insulate humans from the harsh Martian environment. Spanish photographer Dani Caxete snapped this photo of the International Space Station passing in front of the moon earlier in 2017. The image was captured during one of the space station's 15 daily orbits at a speed of more than 17,000 miles per hour or about 5 miles per second. Nearly the size of a football field, the space station can be seen with the naked eye as it passes overhead. Individuals so inclined can sign up to receive text alerts from NASA as the orbiting laboratory approaches their neck of the woods. Link to comment Share on other sites More sharing options...
