United States and a high-speed collision detector destruct month

???? WASHINGTON, April 18 (Reporter Lin Xiaochun) NASA ground controllers on the 18th said that due to fuel exhaustion, the United States' Environmental lunar atmosphere and dust detector (LADEE) "according to plan high-speed impact of the back of the moon, but no person or detector to capture its final journey.

???? According to NASA news release, the vending machine the size of the lunar probe between the U.S. Eastern Time at 0:30 on the 18th to 1:22 Cheap Cardinals Jerseys (Beijing time 12:30 to between 13:22) in the fall and the collapse of the lunar surface, many parts due to Cheap Jets Jerseys the high temperatures generated when the impact vaporized.

project scientist Rick Cheap Bengals Jerseys Yifei Ke said: "'lunar atmosphere and dust environment detectors' impact speed of 3,600 miles per hour (about 5800 km), which is the high-energy rifle bullets flying speed about three times this speed bump, nothing 'soft' at all. problem is just that it is caused by a pothole on the Cheap Colts Jerseys hillside, or a flat piece of wreckage scattered over the lunar surface. "

???? "lunar atmosphere and dust environment probe" was launched last September, and a month after entering lunar Cheap Saints Jerseys orbit. The mission of flying: a test between the Earth and the Moon broadband communication systems; analysis lunar thin atmosphere; investigate the causes of the mysterious radiance "Apollo" spacecraft on the moon before sunrise horizon astronauts saw.

???? main task of the detector at the end of March this year, due to the amount of fuel needed to keep it flying depleted, plus it can not return to Earth, NASA consciously make this probe hit back to the moon. Away from the impact site, where all previous on Earth can not be observed.

???? 4 May 11, ground controllers were the last track detector control, but because of the lunar gravitational field is very uneven, NASA estimated time of impact was 21 or 21 this month some point prior.

NASA says the next few months, ground controllers will use another detector America - "Lunar Reconnaissance Orbiter," looking for "lunar atmosphere and dust environment probe" of the impact site, to determine the specific impact time.
