The blurry image appears to show 18 different blobs of starlight – though they are actually all the same star, shaken up because the pieces of mirror in the telescope are not yet properly aligned...Over the next month or so, Nasa's engineers will adjust the telescope so that those 18 dots merge
into one..."The entire Webb team is ecstatic at how well the first steps of taking images and aligning the telescope are proceeding." [Image posted in Comment #1]

HD 84406 is located in the constellation Ursa Major, which means "Big Bear" in Latin. The Big Dipper asterism (or star pattern) is actually part of this constellation, and it's the tail of this furry beast. The
star has a visual magnitude of about 6.9, which is too dim to see with the naked eye. To see the star, you'll need a telescope or high-power binoculars. Here's our guide for the best telescopes for 2022, and our guide for the best binoculars may help you find the right pair to hunt Webb's star. A bright point like HD 84406 provides...

NASA The James Webb Space Telescope has fired its thrusters and reached its orbital destination around a million miles (1.5 million kilometers) away from our planet, NASA said Monday, a key milestone on its mission to study cosmic history. At
around 2:00 pm Eastern Time (1900 GMT), the observatory fired its thrusters for 5 minutes in order to reach the so-called second Lagrange point, or L2, where it will have access to nearly half the sky at any given moment. "Webb, welcome home!" said NASA Administrator Bill Nelson in a statement. "We're one step closer to uncovering the mysteries...

At 11:30 AM (PST) - 62,500 miles from L2 - 836,000 miles from Earth - Current speed 555 mph - Speed will decline to about 325 mph before it enters L2 orbit in five days - Temperature of "hot" side has been stable since sun shield deployment, 133F and 50F - Cold
side shows modest cooling, minus 340F and minus 330F - When operational, the cold side will be minus 388F - Webb actually has heaters to keep temp loss very slow to protect equipment and to avoid ice forming from any Earth moisture - Currently, Webb is retracting pegs...

This week, we have started the process of moving the mirror segments (all primary plus secondary) out of their stowed launch positions...Each mirror now needs to be deployed out by 12.5 millimeters (about half an inch) to get the pegs clear from the sockets...Each of the mirrors can be moved with incredibly
fine precision, with adjustments as small as 10 nanometers...[Link also includes two helpful videos].

There is no transcript of this video. There
is a great interview with Dr. John Mather, who is the senior project scientist on the James Webb Space Telescope (JWST). The Youtube is very well done in explaining the JWST, what it is designed to do, how it is supposed to work, and how it will be deployed and emplaced over the next month.

Explanation: There's a big new telescope in space. This
one, the James Webb Space Telescope (JWST), not only has a mirror over five times larger than Hubble's in area, but can see better in infrared light. The featured picture shows JWST high above the Earth just after being released by the upper stage of an Ariane V rocket, launched yesterday from French Guiana. Over the next month, JWST will move out near the Sun-Earth L2 point where it will co-orbit the Sun with the Earth. During this time and for the next five months, JWST will unravel its segmented mirror...

NASA’s James Webb Space Telescope successfully launches. It’s a complicated mission for world’s most powerful telescope
|

Boston Globe ^
| 25 December 2021 | MARCIA DUNN (AP) via Boston Globe
The world’s largest and most powerful space telescope rocketed away Saturday on a high-stakes quest to behold light from the first stars and galaxies and scour the universe for hints of life. NASA's
James Webb Space Telescope soared from French Guiana on South America’s northeastern coast, riding a European Ariane rocket into the Christmas morning sky. The $10 billion observatory hurtled toward its destination 1 million miles (1.6 million kilometers) away, or more than four times beyond the moon. It will take a month to get there and another five months before its infrared eyes are ready to start scanning...

NASA and its international partners are counting down to a Christmas Day launch of the most expensive science probe ever built, a $10 billion telescope designed to capture starlight from the first galaxies born in the fiery crucible of the Big Bang. Billions over budget and years behind schedule, the James Webb
Space Telescope is targeted for blastoff from the European Space Agency's Kourou, French Guiana, launch site at 7:20 a.m. EST Saturday atop an Ariane 5 rocket, weather permitting. Equipped with two solid-fuel strap-on boosters, the workhorse rocket will propel Webb away from the northeast coast of South America...

| NOVEMBER 23, 2021 | By NASA
The launch readiness date for the James Webb Space Telescope is moving to no earlier than December 22 to allow for additional testing of the observatory, following a recent incident that occurred during Webb’s launch preparations. The
incident occurred during operations at the satellite preparation facility in Kourou, French Guiana, performed under Arianespace overall responsibility. Technicians were preparing to attach Webb to the launch vehicle adapter, which is used to integrate the observatory with the upper stage of the Ariane 5 rocket. A sudden, unplanned release of a clamp band – which secures Webb to the launch vehicle adapter –...

The massive space telescope, featuring a 21 foot mirror, and a tennis court-sized protective cage, is far too large to stick inside a plane. Instead,
NASA will have to ship the massive mirror right through the Panama Canal for its eventual launch in French Guiana — and NASA is worried that the journey could attract robbers. The shipping time and location will be hush-hush to ward off any extremely ambitious thieves. All we know is that it will sail off in late summer. It’s an especially harrowing sea passage for a project that has been going on for over two...
