NASA James Webb Space Telescope On Christmas morning the French Guiana departed from the ELA-3 launch complex at ArianSpace on a European spaceport. If you want to see the launch, watch the replay of the live stream Here. This Monday, about a month later, the web, as NASA often refers to it, Has reached its final orbit About 1.5 million kilometers (about 1 million miles) from Earth near the second Sun-Earth Lagrange Point, or L2.
Engineers and researchers have been working on incredible space telescopes since the 1990s. The $ 10B project has been around for decades, so its arrival in L2 is a really important occasion for everyone involved. This is a big issue for everyone else, as JWST will join the Hubble Space Telescope in our quest for more knowledge about our universe and its origins.

‘Web, welcome home!’ Says NASA Administrator Bill Nelson. ‘Congratulations to the team for their hard work in ensuring Webb’s safe arrival at L2 today. We are one step closer to unraveling the mysteries of the universe. And I can’t wait to see the first new view of the web universe this summer! ‘
Yeah Al that sounds pretty crap to me, Looks like BT aint for me either. The primary mirror segment and the secondary mirror have been deployed from their launch positions, so engineers are now in the process of three months to align the telescope’s state-of-the-art optics with ‘almost nanometer accuracy’.

Webb spent the last month working his way up the L2 while unveiling his Sunshield and other components. As of January 19, the web has completed the installation of 18 segments featuring the initial mirror.
The James Webb Space Telescope has four onboard cameras, including NIRCam, NIRSpec, NIRISS and MIRI. Telescope cameras can look across the past and across longer wavelengths than Hubble, so we need to look at more incredible photographs and learn a lot more about how the first galaxies were formed when the web started to be fully operational in a few months. If you want to know more about Space Telescope and its instruments, watch the video below for a long time DPreview Reader Dr. Kevin Heinline.
The web’s final orbit allows it to have a wide view of the universe ‘at any moment’ and ensures that the ship’s instruments are cool enough to perform ‘optimal science’. The web has been revising minor courses since its launch. Final course modifications added only 1.6 meters per second (3.6 miles per hour) to the web’s speed, slowly moving it into orbit around L2. The team has worked hard to save as much fuel as possible for the web’s lifetime use. Minor adjustments will be required over time to stay in JWST orbit. In order to cope with the effects of the solar radiation pressure on the telescope’s large sunshield, it has to be self-propelled from time to time.
Bill Oches, Web Project Manager at NASA’s Goddard Space Flight Center, said: “Last month, JWST achieved amazing success and paid tribute to all the people who have spent many years and even decades to ensure mission success.” “We are now on the threshold of mirror alignment, instrument activation and commissioning, and wonderful and amazing discoveries.”

| Arianespace’s Ariane 5 rocket launches onboard with NASA’s James Webb Space Telescope on Saturday, December 25, 2021, from the ELA-3 launch zone in the European spaceport at the Guyana Space Center in Caro, French Guiana. The James Web Space Telescope (sometimes called the JWST or Web) is a large infrared telescope with an initial mirror of 21.3 feet (6.5 m). The observatory will study every step of cosmic history – from within our solar system to the farthest observable galaxy in the universe. ‘

The basic assumption was that the web had a scientific life of five to ten years. However, Arian 5 did such a thing Excellent and precise work With the introduction of the web, NASA now believes that the web has a significantly longer lifespan than 10 years of science. We can’t wait to see what the team achieves.
