US to study Moon’s gravity field

US to study Moon’s gravity field
The Earth’s closest planet the Moon is still a misery to many. Innumerous probes about the Moon are still hovering around. Twelve American Astronauts walked on to the moon and brought soil and rocks from there. During the week end a twin space craft look like washing machine are set to enter the latest Lunar orbit. The space crafts will gauge the gravity field and find out the things under the core. The project manager David Lehman of NASA Jet Propulsion Lab confirmed that one of the grail probes short for recovery of gravity and the internal lab will slow down the engine. The following day next craft will do the same. The cosmic ray can also prevent the engine ignition which in turn affects the boosting in to the right orbit.
