NASA's UARS satellite, which began to fall uncontrollably a few days ago, reached Earth this morning between 5.23 and 7.09 Spanish peninsular time over the Pacific Ocean, as confirmed by NASA, although there is still no data on its exact location.

This morning the UARS satellite (Upper Atmosphere Satellite), which NASA launched in 1991, is scheduled to re-enter the atmosphere, five years after completing its scientific mission. The big question everyone asks is: where will it fall?

NASA's Johannes Kepler satellite has discovered a planet like Luke Skywalker's hometown in the Stars Wars movie, Tatooine. Baptized as 16-b, it has the same characteristics as the film: cold temperature, gaseous atmosphere and desert climate. It is also circumbinary, that is, it revolves around two stars.

The Lunar Reconnaissance Orbiter (LRO) probe has obtained the most accurate images seen to date from space of the places where the Apollo 12, Apollo 14 and Apollo 17 spacecraft landed. The photographs show the footprints left by the astronauts on their walks of exploration, as well as the makes of the moon cars they used.

ESA's Mars Express probe has sent new images of a crater called Eberswalde that show what may have been the bed of a large lake at the time when water flowed across the surface of the neighboring red planet, the agency announced. space.

The first nuclear power plant to produce electricity on the Moon, Mars and other planets is now ready to fly. The device uses an innovative fission technology different from that used by land-based nuclear power plants. The new reactor, developed by NASA and the US Department of Energy, will be the size of a suitcase and will not require cooling towers.

Comet Elenin, the last to visit our inner solar system, will pass 35 million kilometers from Earth - that is, more than 90 times the distance that separates us from the Moon - during its closest approach to our planet on October 16. of 2011, so it will not pose any threat.

The Moon may not be as old as previously thought. Scientists at the Lawrence Livermore National Laboratory in California calculated a new age for Earth's only satellite: 4.36 billion years, that is, approximately 200 million less than the figure managed so far.
