I remember being in middle school and reading about how this thing was going to launch in 2008.

How do I launched Webb?

nekom: How do I launched Webb?


They need to do way instain congress> who kill thier webbys, becuse these webbys cant fright back? It was on the news this mroing a senator in dc who had kill nasa three projects, they are taking the three project back to floriduh to lady to rest. my pary are with the astronomers who lost their funidng ; i am truley sorry for your lots

Even Trump can't derail or fark this up, right?

It's called time dilation, duh. We may never know what happens beyond the James Webb space telescope event horizon.

I can't wrap my mind around the folding needed to fit into the rocket. The package in the Ariane rocket is 15 feet wide (and 53 feet long). Then it unfolds to this:

This is the one that will be looking for the black hole at the Milky Way's center, right?

During hurricane Harvey, a dedicated crew of NASA employees stayed on-site to continue the thermal-vacuum testing for the Webb and keep it on schedule as best they could. The integration testing is taking a bit longer but it is necessary. Unlike the Hubble, we can't fix the Webb once it is on-orbit.

I've actually done some work on space instruments, and watching the JWST deployment sequence gives me massive anxiety. There are...not a small number of steps to unfold the damn thing. JWST's is an amazing mission and I'm obviously rooting for NASA to pull it off, but if JWST fails, I suspect it will imperil NASA in a way we've never seen before.

I'm pretty sure I covered that earlier in the thread.

fark I'd just hyped myself up about it's 2018 launch date yesterday.

From Wikipedia: "In June 2011, it was reported that the Webb telescope would cost at least four times more than originally proposed, and launch at least seven years late..."

Some of my colleagues are astrophysicists who have some involvement in this project. They are unanimously furious at the original JWT team, who they accuse of deliberately low-balling both cost and construction time estimates and hoping that once they got the initial funding that the government wouldn't cancel it.

Remind your colleagues that the original JWT team did the right thing, because if they hadn't low-balled the cost and time estimates, the damn thing wouldn't have been approved in the first place.

"We need something better than Hubble."
"But Hubble can see forever. How much does better cost?"
"Um... a billion and a half?"
"OK, that's do-able. We were worried you were gonna say ten billion. That would have been way too much for a nerd telescope."

Seems to be a common thing with NASA project estimates

Uh...yeah, me too. However, just because it has been employed by an in-orbit astronaut doesn't mean you can label it a "space instrument".

But assuming you are American or a Brit, there is a decent chance you come to it more naturally than a Canadian.

That was extraordinary. Thanks.
