The twin spacecraft NASA has sent Grail. To explore the moon. For mapping the internal structure. The star of the family, this is the first video. And is expected to arrive at the end of the year ...
Foreign news agencies reported on 11 September that the administration division of the National Air and Space or NASA spacecraft reveal that the emission twins 'Grail' to the rocket, called 'Delta E' from The launch of the Air Force. Cape Cana West Central Florida at 9:08 pm Saturday (local time) by sending them a survey and mapping of the inner core of the moon for the first time.
The George Miller of NASA analysts expected. The two spacecraft will take a trip to the Moon for about 3 months and will travel to the poles of the Moon during the New Year's Day. And when arrived. The two spacecraft will drift away from the surface of the moon, about 55 km and a distance of approximately 60-225 km and takes about 40-day mission.
This is the plan. The two spacecraft will use gravity. Surveying and mapping the interior of the moon. And will know what is inside the moon. The scientific world has very little knowledge in this area. And may lead to a more remote areas, or 'dark side' of the moon has never been explored before. This may answer these questions, scientists have said. Once the world has two moons. But I have been together as a nation and the moon or not.
Mr. Bobby Miguel Four NASA scientists said the mission's twin spacecraft Grail. It is the first mission. An exploration of the moon's internal structure seriously.
Scientists have always believed that The moon are caused by an asteroid crashed into Earth in size, equivalent to the formation of new capacity. The thin parts of the world that continues to spill out to cool. And form a moon. But this theory can not explain. Why the moon is still hot. Why is the sea, and LAVA. Which later hardens into crystals. The mission of exploring the moon. To test for an explanation of all this.
The NASA budget to U.S. $ 500 million, or about 1.5 billion baht to build interest in both vehicles. And in November. NASA will send a spacecraft to Mars is expected to take approximately two years.
