Philae Lander Runs Out Of Battery And Enters Deep Sleep | IFLScience

Philae Lander Runs Out Of Battery And Enters Deep Sleep | IFLScience.

“It’s been a tense week for space exploration, to say the least. But after a nail biting few days that kept millions around the world on the edge of their seats, with fingers and toes tightly crossed, the ESA has announced that the Philae lander has gone to sleep.

The drama began to unfold shortly after cheers were exchanged as Philae made its momentous arrival onto comet 67P/Churyumov-Gerasimenko on Wednesday. The probe’s anchoring harpoons failed to deploy as it made contact with the surface, and because the gravity on the comet is very weak, Philae rebounded. It took two hours for the robot to finally settle, but unfortunately it ended up stuck along the edge of a crater which blocked the sun’s rays from reaching its solar panels.”

NASA’s Hubble Space Telescope Spots Mars-Bound Comet Sprout Multiple Jets

“NASA released Thursday an image of a comet that, on Oct. 19, will pass within 84,000 miles of Mars — less than half the distance between Earth and our moon.

The image on the left, captured  March 11 by NASA’s Hubble Space Telescope, shows comet C/2013 A1, also called Siding Spring, at a distance of 353 million miles from Earth. Hubble can’t see Siding Spring’s icy nucleus because of its diminutive size. The nucleus is surrounded by a glowing dust cloud, or COMA, that measures roughly 12,000 miles across.”

NASA Mars Rover’s Next Stop Has Sandstone Variations


Sandstone layers with varying resistance to erosion are evident in this Martian scene recorded by the Mast Camera on NASA’s Curiosity Mars rover on Feb. 25, 2014, about one-quarter mile (about 400 meters) from a planned waypoint called “the Kimberley.” Image Credit: NASA/JPL-Caltech/MSSS

“Variations in the stuff that cements grains together in sandstone have shaped the landscape surrounding NASA’s Curiosity Mars rover and could be a study topic at the mission’s next science waypoint.
On a journey with many months yet to go toward prime destinations on the lower slope of Mount Sharp, Curiosity is approaching a site called “the Kimberley.” Scientists on the team picked this location last year as a likely place to pause for investigation. Its informal name comes from a northwestern Australia region known as the Kimberley. The Martian site’s geological appeal, based on images taken from orbit, is that four types of terrain with different rock textures intersect there.”
