The James Webb Space Telescope to erfüllen.Das Science Friday video.
A full model that James Webb Space is the proposed successor to Hubble, telescope on the Rennstrecke--performances at science conferences and festivals.Science Friday met with the Observatory and spoke to its handler in New York City's battery Park.

Are from NPR SCIENCE Friday, listen. I am Ira Flatow.
Time now for flora - Hi, flora.
FLORA LICHTMAN: Hello.
FLATOW: Flora Lichtman's video pick of the week.It is great with our video Pick.Another here is one.
LICHTMAN: Thanks, IRA.
FLATOW: have you what for us this week?
LICHTMAN: It's a little meet - and - successor to the Hubble greets with a telescope that you may be unfamiliar with noch.Der is the James Webb Space Telescope, and it has not yet started was. It is due until 2014.
FLATOW: Mm-hmm.
LICHTMAN: But as part of its kind coming out party, I think, was parading NASA art to this full scale model around the world. It was after Munich and Dublin, Seattle...
FLATOW: It has this little has sticker on it from all these different places.
(Soundbite laugh)
LICHTMAN: Yes, there are tons of images of people, nature, how to give a hug this huge Centre.
FLATOW: Right.
LICHTMAN: How he came to New York and we met with him and spoke with some his handler, what the James Webb, to do.
FLATOW: It is quite large.I think you've got a good place for you, not to have?
LICHTMAN: Yes, it was Battery Park, the city centre.It takes a large area, because it is the size of a tennis court.
FLATOW: Wow.
LICHTMAN: On - so you think that's the amazing thing about the way that see it, is something the size of a tennis court a million miles away, is up in the room, where it is as received?
And what was clean was hearing on the engineering of this device.So basically, you have it folds up like a know how a flower which then, once will unfold it gets to its destination.But as you can imagine, there are a lot of tricky engineering...
FLATOW: Yes.
LICHTMAN:... in.
FLATOW: Yes.So if you go to our website at sciencefriday.com, you can see flora's video, an interview with the people there, and see, how to do this - almost magically to unfold.It's amazing how.
LICHTMAN: It's pretty amazing.And I think the other - one of the other tricky things about building we learned was, that this huge mirror haben.Und that are mirror like - it's James Webb as eight out of Hubble's Optics - Optics passen.So much larger reden.Und that James Webb, by the way, is an infrared Observatory and Hubble is we sichtbar.Und what this should allow us to do further back in time to see.
But part of this builds these huge mirrors.And you said that you actually to get atoms shave at have...
FLATOW: It is so precise, you've got it to shave the atom.
LICHTMAN: That's right, thats right get only to prescription unglaublich.Ich my so you focus the light in the other mirrors, which then collects and...
FLATOW: Are to not use a ShamWow to clean up.
LICHTMAN: No, in fact.
(Soundbite laugh)
LICHTMAN: No, and it is from beryllium, also, because the other thing I had not thought, is it pretty cold in the room, it turns out...
FLATOW: Yes.
LICHTMAN:... like so you have to make negative 400 degrees Celsius.Und sounds like this is this special Materialien.Es part - it's part of the challenge only find, what material you make on a mirror or mirror this - can work these conditions.
FLATOW: Ja.Und I think - and, of course, its shape is, has to keep because it to a mirror set you're going to make a certain form, it must be - that is why you use the material.
LICHTMAN: Right.Und test it here on the Erde.Sie have kind of make it in a recipe that at room temperature, another form is know as there in colder temperatures it so a quantity, kind, tricky Engineering.Und fact, it took my 20 Jahre.Ich, the plans for this telescope began this - happens before Hubble went.
FLATOW: Wow.Hoffen we, you don't have this pair of glasses on this one to put.
(Soundbite laugh)
FLATOW: I mean fix while it here in the ground.
LICHTMAN: I think it will be difficult, because there the Lagrange point number two, so headed...
FLATOW: This is far out.
LICHTMAN: This is quite far.
FLATOW: Ja.Gut - and you can see that this James Webb telescope it most - flora went out there with a camera and interviewed people in Battery Park here in New York.Und on our website at sciencefriday.com, pick of the week there on the left, click on it, click on a larger portion of it and watch it and share with your friends to go.
LICHTMAN: please.
FLATOW: Thank Dank.Danke, flora.
LICHTMAN: Thanks, IRA.
FLATOW: Have a great weekend.
