Thanks for posting the videos Flyaway. Highly interesting.

NASA says it is holding to a March 2021 launch date for the James Webb Space Telescope, but a new reportfrom the US Government Accountability Office suggests the mission probably will not happen then.

Because the space agency and the telescope's prime contractor, Northrop Grumman, continue to tackle serious technical problems, the report estimates that there is only a 12 percent chance that the large space telescope will launch in March 2021. It is due to lift off on board an Ariane 5 rocket from the European Space Agency's spaceport in Kourou, French Guiana.

Not so good news for the Webb space telescope. What happens next? A delay to the launch into 2022?

This is the GAO. NASA will probably write a reply which will give a better idea of where things stand. 70% confidence isn't exactly solid so March should be considered optimistic.

Actually that's a lot less folding than I thought. I had assumed with all of those separate mirrored faces that there would be more than two folds of the primary mirror. That said, Ican't imagine how they are possibly going to align those two pieces during deployment with the kinda of microscopic tolerances that will be required. The rest of the deployment looks fairly straight forward. But certainly the nature of its deployment is extremely high risk in such an expensive project.

Each mirror is attached to the frame by a set of actuators. Once the mirror is unfolded, the actuators will be used to finetune mirror positions.

Are they using this program as a front for another round of classified spy satellites?

Probably they are just fucking up. If you remember correctly, the Hubble went through a similar process...my dad has a paper weight dating to 1985 for that project. Hubble ultimately turned out to be worth it...here's hoping Web does too. It is a much more ambitious project with a lot more science to be learned if it works...but obviously, more expensive with no hope of repair if anything goes wrong.

Especially since it is going to be placed in orbit around the second Lagrange point, so they better make sure that everything is working okay before launch, or it will be an expensive mistake.

Nope, this latest, relatively minuscule slip is 100% motivated by Coronavirus’s impact on the work their doing. This article is pretty pointless and anemic (to be expected because of who wrote it) because NASA has yet to release a new post-COVID launch date; the language of relevant NASA officials suggests the delay could be as small as a month or two, as they’ve mentioned they could still hit the original March launch date, but not without rushing (which is something you really don’t wanna risk with JWST).

Actually I think that’s a bit of unjustified comment concerning the author as I usually find his stuff pretty good.
