Tiny Satellites could be "Stars Stars" for great Mass Teles



Long-term NASA space telescopic plans, in fact, recurrent crop are very large.

There are more than 3,900 valid planets outside our solar system. To find out more about these planets, since there are oxygen, water or other signs of their life, we need more sophisticated cucumber with very similar devices and mirrors that are as big as those in sights on the Earth.

Such chocolates are today's challenges such as maintaining their parts enough to look good at foreign things. A new survey was published this week Journal of Journalism Describing a system that would using a second satellite for example laser light to help lock large telescopes to distant objects.

Laser Light Display

NASA is already planning future space telescopia. The telescope James Webb was discharged with a 6.5-meter diameter and 18 segment mirror sections. Telegopics in the future may be as big as 15 meters, with more than 100 specimens. Maintaining this mirror, which is shared at the same target, is one of the key challenges for a mirror telegopy by section. The fastest movement in any part would be enough to throw it off completely.

Now, MIT engines have been using a second satellite in the shoe box to be a "guiding star" by pressing it. Provides a clear light to use a telescope as a reference point. By placing the light in a range of telescope views, the telescope would be better able to locate any movement in its instruments and keep more secure at the target. Such a system is already capable of modern technology and would determine the need for integrity in mirror co-ordination, and & # 39; save time, money, and which could prevent delays such as those who are in a position; affecting Telescope James Webb.

Looking forward

The idea is to use artificial light as a comment point; Encouraging the way in which scientists on the ground have been using real star for the same reason for more than a hundred years. This is the first time that a small CubeSat could be used to display the process in space.

"The reason why this is now NASA needs to make a decision in the next couple of years is that the big speeds we have will be a priority in the coming years," said Ewan Douglas, main author of her document. "That decision is currently happening, just as the conclusions for Teileascop Space Hubble were pulled in the 1960s, but it did not start until the 1990s."
