I'm very glad that the James Webb Space Telescope was one of the winners.

JPL: Two Cameras Offer View of JWST in Clean Room

Two Cameras Offer View of Webb Telescope in Clean Room
NASA JPL-Caltech | JWST | 2012 July 02

Members of the public can track the progress of the upcoming James Webb Space Telescope inside a NASA clean room, where the recently delivered Mid-Infrared Instrument (MIRI) will be integrated into the science instrument payload. Two cameras show the giant clean room at NASA's Goddard Space Flight Center in Greenbelt, Md. Online screen shots from the two clean-room cameras, affectionally dubbed "Webb-cams," are updated every minute.

Developed by a consortium of 10 European institutions and NASA's Jet Propulsion Laboratory, Pasadena, Calif., and delivered by the European Space Agency, MIRI is the first Webb telescope instrument to be completed.

The clean room is generally occupied Monday through Friday from 5 a.m. to 1:30 p.m. PDT (8 a.m. to 4:30 p.m. EDT).

The Webb-cams can be seen online at: http://jwst.nasa.gov/webcam.html .

Of the James Webb Space Telescope's four science instruments, only MIRI can see light in the mid-infrared region of the electromagnetic spectrum. This unique capability will allow the Webb telescope to study physical processes occurring in the cosmos that the other Webb instruments cannot see.

MIRI's sensitive detectors will allow it to make unique observations of many things, including the light of distant galaxies, newly forming stars within our own Milky Way, and the formation of planets around stars other than our own, as well as planets, comets and the outermost debris disk in our own solar system.

The Webb Telescope project, managed at Goddard, is the world's next-generation space observatory and successor to NASA's Hubble Space Telescope. It is a joint project of NASA, the European Space Agency and the Canadian Space Agency.

NASA Completes Webb Telescope Review

NASA Completes Webb Telescope Review,
Commits to Launch in Early 2021

NASA | JWST | 2018 Jun 27

The Independent Review Board (IRB) established by NASA to assess progress on its James Webb Space Telescope has unanimously recommended that development on the world’s premier science observatory should continue; NASA has established a new launch date for Webb of March 30, 2021.

A report issued by the review board addresses a range of factors influencing Webb’s schedule and performance, including the technical challenges and tasks remaining by primary contractor Northrop Grumman before launch.

Read the full report and NASA’s response at:

GSFC: JWST Has Been Assembled for the First Time

Post by bystander » Thu Aug 29, 2019 8:17 pm

JWST Has Been Assembled for the First Time
NASA | GSFC | JWST | 2019 Aug 28
Reaching a major milestone, engineers have successfully connected the two halves of NASA’s James Webb Space Telescope for the first time at Northrop Grumman’s facilities in Redondo Beach, California. Once it reaches space, NASA’s most powerful and complex space telescope will explore the cosmos using infrared light, from planets and moons within our solar system to the most ancient and distant galaxies.

To combine both halves of Webb, engineers carefully lifted the Webb telescope (which includes the mirrors and science instruments) above the already-combined sunshield and spacecraft using a crane. Team members slowly guided the telescope into place, ensuring that all primary points of contact were perfectly aligned and seated properly. The observatory has been mechanically connected; next steps will be to electrically connect the halves, and then test the electrical connections. ...

Next up for Webb testing, engineers will fully deploy the intricate five-layer sunshield, which is designed to keep Webb’s mirrors and scientific instruments cold by blocking infrared light from the Earth, Moon and Sun. The ability of the sunshield to deploy to its correct shape is critical to mission success. ...

This saga continues to unfold. May there be no unforeseen wrinkles.
Haste makes waste. Caution is the better part of Valor.
Launch the Greatest American shield ever made into space!
Greater even than Captain America's mighty shield!
Aliens will find Earth absolutely amazingly beautiful and fragile to behold. But if they get close enough, they'll see 7,000,000,000 of us and think "Uh oh, that's a lot for such a small planet. Wonder if we should help?"

Good to see your dormancy has ended mjimih. Nice to hear from you.

Thanks Bruce!
Been watching Anton Petrov's Youtube channel aka What Da Math. https://www.youtube.com/whatdamath/featured
he posts everyday something new, with his expert use of Universe Sandbox2 as his full screen backdrop.
He gives me my daily fix. And with so many new discoveries and new theories lately that he touches on & explains, i wanted to check in here again too and see what's up.

James Webb question; Which has a higher risk of failure :( the launch, or the unfolding of all the parts of the telescope?
And how do they prevent damage during launch. The vibrations and g force at launch must be enormous obstacles to overcome for such a delicate instrument.
