Hopefully it all goes right. >> a lot of work. we're watching the animation of the origami unfolding. it's going to be a delicate process. at what point do you think we'll start seeing the images and data sent back from this telescope? >> it's going to take about six months because it's going about a million miles away from earth. and because it's so far, it's going to be 100 times more powerful than the hubble space telescope but also means that if something goes wrong, astronauts are not going to be able to fly out and fix it like they did for the hubble space telescope. so really is a very ...
Hopefully some day perhaps answer that question we've been trying to get answered for so, so long which is, are we alone in the universe. but so many of the scientists that have worked on the webb space telescope tell me the thing they believe that will be the greatest accomplishment is to answer some of the questions that have not even been asked yet. that we don't even know to ask. and so just imagine, some of these scientists and engineers, they have been working on this telescope for more than 20 years and how it all comes down to tomorrow morning, 7:20 in the morning, eastern time on chri...
But the instruments are so powerful, the telescope is so powerful, almost anywhere we want, we are going to be breaking new ground in a huge way. the telescope is so big, to get into space, it had to be folded up like origami. it has been busy unfurling, first its sun shield, which is the size of a tennis court, but now a vital stage of the process is beginning. the mirror is the most important part of the telescope. its two folded sides open up and lock into place. at 6.5 metres wide, it is so wide that it consists of 18 separate hexagonal segments. they are made from beryllium, a stiff and l...
