Update:

James Webb Space Telescope's Golden Mirror

Inside the clean room at NASA's Goddard Space Flight Center, the golden James Webb Space Telescope is viewed from overhead with its secondary mirror booms stowed. This is the position the secondary mirror will be in during launch. In the next few months, engineers will install other key elements, and take additional measurements to ensure the telescope is ready for space.

Science Instruments of NASA’s James Webb Space Telescope Successfully Installed

With surgical precision, two dozen engineers and technicians successfully installed the package of science instruments of the James Webb Space Telescope into the telescope structure. The package is the collection of cameras and spectrographs that will record the light collected by Webb’s giant golden mirror.

“Designing and building something of this magnitude and complexity, with this amount of new technology, is far from routine,” said Dunn. “While every project has their share of ups and downs, the JWST team has had to work through a lot over the life of this project. The character and dedication of this team is extraordinary, they’ve always recovered brilliantly, and they’ve made many personal sacrifices to get us to this point.”

Update:

How Cold Can You Go? Cooler Tested for NASA Telescope

A first-of-its-kind cooler for NASA's James Webb Space Telescope, scheduled to launch in 2018, has completed testing at NASA's Jet Propulsion Laboratory in Pasadena, California.

About the size of a household fridge, this cooler has a far more important role than chilling sodas and snacks. It is key to catching faint whispers of light from the very first stars born in our universe billions of years ago. The cooler will chill one of the Webb telescope's four instruments, called the Mid-Infrared Instrument, or MIRI, which will also study other stars, exoplanets and galaxies.

Update:

The Complex Material Engineering of NASA's Webb Telescope Sunshield

NASA and its industry partners developed a lightweight, robust way to protect the telescope and mirrors from the sun’s infrared radiation in the material that makes up the sunshield. Some of the things that make the sunshield unique are its strong yet ultra-thin material, special kite-like shape, and the special role of its layers.

Update:

NASA Seeks Picometer Accuracy

With NASA funding, a team of scientists at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, has begun working with an Arizona-based company to develop a highly sophisticated laboratory tool — a high-speed interferometer — capable of assuring picometer-level stability, a feat not yet accomplished.

Once it launches in October 2018. From its orbit 930,000 miles from Earth, it will study every phase in the history of our universe, from the first luminous glows after the Big Bang to the evolution of our own solar system. Among many other firsts, Webb will carry a 21-foot primary mirror made of 18 separate ultra-lightweight beryllium segments that unfold and adjust to shape after launch.

Update on JWST website concerning Proxima b:

"This is really a game-changer in our field," said Olivier Guyon, a planet-hunting affiliate at NASA's Jet Propulsion Laboratory, Pasadena, California, and associate professor at the University of Arizona, Tucson. "The closest star to us has a possible rocky planet in the habitable zone. That's a huge deal. It also boosts the already existing, mounting body of evidence that such planets are near, and that several of them are probably sitting quite close to us. This is extremely exciting."

Updates:

A Mechanical Harmony to NASA's Webb Telescope Sunshield

Like a car, many mechanical pieces in the Webb telescope's sunshield will work together to open it from its stored folded position in the rocket that will carry it into space.

The sunshield support structure contains well over 7,000 flight parts, including springs, bearings, pulleys, magnets, etc. In addition, the sunshield has hundreds of custom fabricated pieces. Most mechanical pieces were developed exclusively for the sunshield, with a few from existing designs.


Testing the James Webb Space Telescope Pathfinder

The James Webb Space Telescope Pathfinder structure has been configured for the Thermal Pathfinder Test at NASA Johnson Space Center's giant thermal vacuum chamber, called Chamber A. The Pathfinder is a test version of the structure that supports the telescope. This is where end-to-end testing of the actual telescope will occur in 2017.

I think today they have officially declared assembly of the telescope as complete, and are now off to the testing and fine-tuning phase. There's a 40 minute news conference on the NASA YouTube channel.

The JWST has ended its 100 days stay in the cryogenic chamber A at Houston and will be transferred to Grumman-Northrop in California for final assembly on the launch vector. So far everything seems OK.

So how much of it will be disassembled for the final journey to the launch pad? How many shipping containers/airplanes will be necessary? Then, once reassembled, I suppose it'll be in a compacted state until it reaches wherever it's desired location is in outer space, and then it'll unfurl like a really wild origami puzzle, I imagine.
