In the "we want to build these in the future" part of the pipeline, so way the hell out. They know they're not competitive any more, but don't have anything being built as a reusable alternative to SpaceX yet.

Thanks Russia

I had thought the US, Russia and China as well had use missile strikes to decommissioned satellites plenty of times before?
From articles I was reading the other tests were done in a much more controlled manner that ensured less debris going into orbit and becoming an issue for space travel. Previous tests were also announced with various space agencies so they could be done safely. This one was done without warning, done on a satellite higher up in orbit and created lots of sizeable debris that needs to be tracked and posed a threat to the ISS.

NASA x SpaceX to launch a rocket to smash into an asteroid to prevent a future collision with Earth.
Scheduled launch is 1:20 AM ET.Elon Musk’s SpaceX is set to launch a first-of-its-kind planetary defense mission for NASA in the early hours of Wednesday morning, sending the spacecraft on its way to intentionally crash into an asteroid.
“We’re smashing into an asteroid,” NASA’s Launch Services Program senior launch director Omar Baez said during a press conference. “I can’t believe we’re doing that”
Known as the Double Asteroid Redirection Test (or DART) mission, the space agency is trying to learn “how to deflect a threat that would come” toward Earth, NASA associate administrator of the science mission directorate Thomas Zurbuchen said.
“Rest assured, that rock right now is not a threat,” he said.
Right now is the key.
Inb4 they hit the rock and the impact redirects it to earth.
Not possible. The asteroid they will try to hit is orbiting a much larger one and the kinetic energy should only alter the orbit of the small one by a fraction of a percent. Not enough to make it break away from it's parent body. The spacecraft isn't even as big as a car.
JWST Dec 22 at 7:20 EST.
Fucking stoked, worked on the project a bit and it's been a long ass fucking time coming to launch this shit. Hopefully everything goes to plan and it actually unfolds properly and we don't have an issue like after Hubble launched.

Seems important.

Launch delayed until Dec 24th. Got an email today directing public to visit https://go.nasa.gov/WebbSTEAMDay

It has been delayed again. The new launch window is on Christmas day beginning at 7:20am EST.
Ya know, I saw the thread update notification, and I thought "it couldn't possibly be delayed again, please no."
Thanks Obama.
Pretty typical, thunderstorms and crazy weather down there and mornings are the only good windows but its fairly usual for major missions to delay a bunch on launches and such. At least the thing is all there and ready to go and actually put together! That was the hard part lol
If there is an error they can't go out and fix it like they did with Hubble. Speaking of which, wasn't Hubble's issue that they decided to skip testing the mirror's curvature to save time and money and it ended up being misaligned by the width of a hair screwing up the focal length? I've ran into this before when trying to build my own telescope where I didn't grind the glass enough and when I did a Foucoult test my focal length was way off. I wanted an 8 inch F/6 but end up with an 8 inch F/24.
