For those not up on the project, what are some of the earliest novel types of information we expect to receive from it?

It will take another 6 months before JWST will go into operation it seems. This page has a list of approved programs.

“Images of the first galaxies, the first black holes” iirc from Smarter Everyday’s interview with John Mather, sorry don’t have a time code for you

One of the big numbers that been thrown around is that JWST has 344 single points of failure in its mission. Now that deployment has been completed, is there somewhere that lists how many of those points we have passed?

Earlier quoted context omitted.

Huge. This is the first large telescope observing in far infrared. Some things: - very early galaxies (so far that they are redshifted to far IR). Hence the “looking into the start of the Universe” talk). We know they are there, and that they are unusual and super-interesting, but just can’t see them. I think this is high on the agenda so I’m guessing some PR shots of ancient galaxies are due. - cold objects nearby;…

Even earlier than galaxies, we'll be able to see some of the first stars that existed before galaxies formed. IIRC the telescope will be able to see "back" into 98% of the observable universe.

Yup! If the universe's age were a single year, we're looking back to January 6th. Truly remarkable. :)

Not sure about the points of failure, but according to [1] only four deployment stages remain. So the large majority of point of failure should have been passed already.

>344 single points of failure

How can a system have more that one single point of failure?

If you're in a car being held above the ground by a chain, every single link is a potential single-point of failure.

Word on corners of the interwebz has it that this is gonna prove the existence of aliens (or at least gov. are gonna frame JW as the indicator of alien life)

The sequential deployment process had many possible individual points of failure along the way - if any step went wrong then the full deployment failed.
