It will take an incredible mission conducted by NASA astronauts to ask her glasses and restore his sight. We are in 1993, and it is from this date that the facility will give the measure of his talent and surprise scientists. “Hubble is without doubt the greatest scientific instrument and acknowledged having received the greatest number of successful scientific history,” says Ed Weiler , a NASA officials.
A final servicing mission, in May 2009, allowed the telescope to provide two new instruments capable of up to 600 to 500 million years after the Big Bang “and take up the notes in 2013, with the infrared space telescopeJames Webb Space Telescope / JWST ” , more powerful, “which should reveal the time of the creation of the universe,” ignites AFP.
