Amazing bit of engineering.  Have you seem where its at?

Welcome


James Webb Space Telescope deploys radiator to keep instruments cool

the telescope's Aft Deployable Instrument Radiator (ADIR)  is a 4 foot (1.2 meters) by 8 foot (2.4 m) panel

Today, the first of two primary mirror wings, or side panels, was deployed and latched successfully.
Now that the port side wing panel is locked in place, ground teams will prepare to deploy and latch the starboard panel tomorrow.

Upon completion, Webb will have concluded its major deployment sequence.

James Webb Completely and Successfully Unfolded

^ION:
The Hubble telescope was deployed from Space Shuttle Discovery on April 25, 1990, and has been in operation for more than 31 years.

That's all pretty amazing.  I sure hope we start getting some science from it soon.

NASA has begun a four month-long process of bringing the James Webb Space Telescope into focus so it can start taking pictures of the universe by May.

Wow. That's a long time to get something into focus. I think its utility for sports photography will be very limited.

QuoteWith the successful deployment & latching of our last mirror wing, that's:
50 major deployments, complete.
178 pins, released.
20+ years of work, realized.

Webb Mirror Segment Deployments Complete

"Today, the James Webb Space Telescope team completed the mirror segment deployments. As part of this effort, the motors made over a million revolutions this week, controlled through 20 cryogenic electronics boxes on the telescope. The mirror deployment team incrementally moved all 132 actuators located on the back of the primary mirror segments and secondary mirror. The primary mirror segments were driven 12.5 millimeters away from the telescope structure. Using six motors that deploy each segment approximately half the length of a paper clip, these actuators clear the mirrors from their launch restraints and give each segment enough space to later be adjusted in other directions to the optical starting position for the upcoming wavefront alignment process....

Next up in the wavefront process, we will be moving mirrors in the micron and nanometer ranges to reach the final optical positions for an aligned telescope. The process of telescope alignment will take approximately three months."

Webb space telescope nears its destination almost a million miles from Earth, ready for critical mirror alignment.

Once aligned and its instruments calibrated, Webb will be 100 times more powerful than Hubble, NASA says — so sensitive to infrared light that it could detect the faint heat of a bumble bee as far away as the moon.

January 24: after a 30-day journey into space, Webb arrives at its final destination.

Have you seen the new 3D version, it's pretty awesome

The mission operations team's next major step is to turn off instrument heaters. The heaters were necessary to keep critical optics warm to prevent the risk of water and ice condensation. As the instruments meet pre-defined criteria for overall temperatures, the team is shutting off these heaters to allow the instruments to restart the months-long process of cooling to final temperatures.

When NIRCam reaches 120 kelvins (approximately -244 degrees Fahrenheit, or -153 degrees Celsius), Webb's optics team will be ready to begin meticulously moving the 18 primary mirror segments to form a single mirror surface.

This week, the three-month process of aligning the telescope began - and over the last day, Webb team members saw the first photons of starlight that traveled through the entire telescope and were detected by the Near Infrared Camera (NIRCam) instrument. This milestone marks the first of many steps to capture images that are at first unfocused and use them to slowly fine-tune the telescope. This is the very beginning of the process, but so far the initial results match expectations and simulations.

We have the first (still cross-eyed) images from James Webb telescope.
