The James Webb telescope will replace the Hubble, in the same sense that the PS5 is replacing the Atari 2600. The leap is generational, not incremental. It "sees" in the infrared wavelength, which allows it to see much much further than the Hubble and pierce certain gas clouds. It will also operate at a much further orbit from earth (570km for Hubble vs 1,500,000km for James Webb) and will have a tennis court sized sun shield to keep the instruments at a brisk -394F. And you can see it launch live on Christmas morning! Or if you're reading this after it launched, you can watch the replay. https://www.nasa.gov/nasalive Because of its distance though, it won't be serviceable like the Hubble. Its projected lifespan is 5-10 years. Once the fuel is spent, James Webb won't be able to maintain its orbit and will drift off into space. edit:

25 years, $10,000,000,000 It's extraordinary. There are so many things that can go wrong. I can't imagine how nerve wracking the next 24 hours must be to be one of the engineers that basically dedicated their entire career to this one thing.

That's not a lot of time to work with and with how much money is being spent.

i'm watching First Man and i think i'm at the scene where the guys burn up on the launch tower? did that happen? anyway that should do me for the night, thanks for the intel about the telescope tho EDIT: ohhh boy it happened. tastefully done though, no crispy astronauts Mister Speaker fucked around with this message at 05:58 on Dec 25, 2021 |

i just spent like 2 hours researching this and i can't believe i didn't know about it until now. I saw news months ago about a controversy on the name but i didn't care and ignored it... this is some of the coolest poo poo NASA has done in a long long time i really wish I was going to be up to see it [edit] there are 300 points of failure after it travels 1.5m kilometers from earth into a crazy awesome orbit pattern.... it has to unfold most of the important bits in order for the camera to work and be controllable. It will only be able to stay in this orbit for 5-10 years before it runs out of fuel and flies off into space at a fairly random trajectory in its weird orbit.. time to seize beozo's money and put it into the successor and UBI Wendigee fucked around with this message at 07:23 on Dec 25, 2021 |

Absolute gamechanger. This thing is going to change what we know about outer space. The next 10 years are going to be so exciting. This will be like the Hubble Deep Field times a hundred. Just for fun, here's a remarkable YT documentary on alien life, released a couple weeks ago. https://www.youtube.com/watch?v=saWNMPL5ygk&t=1s

Robo Reagan posted:wait a government project was way over budget and way past due? A thing to know is that a small part of why it cost so much is because congress didn't give it enough funding. It went over budget, and then rather than increasing the funding -- as they'd do for something important like a fighter jet that catches on fire randomly -- they made cuts to NASA's budget instead. NASA has spent 10s of millions just on storage costs. Parts have needed to be replaced due to sitting around too long. Congress literally took lessons from the Zaurg School of Finance and made minimum payments on a layaway telescope.

Starting to think the "gently caress you got mine" body isn't very good at its supposed job.

The lifetime is limited by the amount of fuel used for maintaining the orbit, and by the possibility that Webb’s components will degrade over time in the harsh environment of space. The fuel part is so uncertain because 1) The place they're putting it is unstable and very hard to simulate, so long-term predictions of how much fuel it needs over time are difficult. 2) Different things that the JWST could be taking pictures of will change how quickly it uses fuel. Every new thing it points at represents a tiny amount of fuel used. Nearby things like exoplanets or proto-stars or whatever are faster pictures to take, while looking at the farthest oldest stars is a really long exposure. If we end up taking more pics of close stuff it'll use up the fuel faster, but we still get the same total number of pictures.
