An unmanned U.S. rocket took off heading to the moon
United States, September 11, 2011
From Cape Canaveral in Florida reported that “An unmanned U.S. rocket blasted off on Saturday from the Air Force Station to carry two robotic probes to the moon to discover what is inside”.
As was reported by Reuters “the engine of 37.8 meters, took off from the coast at 13:08 GMT, arching over the Atlantic Ocean as it walked into the orbit”.
The Delta 2 rocket launch took place two days later than was planned because of the strong winds at the launch area and because they had to conduct a technical review of the rocket after the fuel tank was damaged after the failed launch on Thursday.
The twin satellites on board were directed to a point in space 1.5 million kilometers to balance out the gravity of the Sun and Earth.
From there, the satellites of the Interior and Recovery Laboratory of NASA’s Gravity (GRAIL) will approach slowly and extended to the moon, coming back between December 31 and January 1.
GRAIL twin probes are designed to precisely map the moon’s gravity so scientists could find out what lies beneath the lunar crust and if the core is solid, liquid, or a combination of both.
Combined with high-resolution images, current analysis of rock and soil samples taken by the Apollo missions from 1969 – 1972 and computer models, maps of gravity could provide the missing key to the mystery of how was formed and evolved the natural satellite of the Earth.
The ships are connected by radio waves, can detect changes in the strength of lunar gravity as small as one micron, ie, the width of a red blood cell.
