The James Webb Area Telescope launched to nice fanfare on Christmas Day, with the highly effective piece of package promising nice issues through the course of its mission to discover deep house.
Many watching the livestream of Saturday’s launch could have been holding their breath through the countdown, although there was no want to fret. Arianespace’s trusty Ariane 5 rocket did the job, lifting the James Webb Area Telescope to house in an ideal begin to the multi-year mission.
However for the Webb crew — comprising personnel from NASA, the European Area Company, and the Canadian Area Company — the strain gained’t recede till the telescope has absolutely deployed in order that it start its work to discover the universe. And that deployment is much from simple.
The satellite tv for pc’s monumental dimension meant that its myriad of elements needed to be folded right into a compact form in order that it might match contained in the rocket’s fairing for launch.
Over the approaching weeks, because the telescope travels by means of house, every of those elements will routinely transfer into place in a fancy course of that has by no means been tried earlier than. And if any one in every of these deployments goes mistaken, it might properly be curtains for the $10 billion venture.
The excellent news is that the preliminary deployments have gone to plan. They embody the photo voltaic array, which launched and deployed about half-hour after launch, and the gimbaled antenna meeting, which efficiently deployed on December 26.
“Our crew simply deployed the gimbaled antenna meeting, which incorporates Webb’s high-data-rate dish antenna,” NASA mentioned in a tweet. “This antenna will likely be used to ship a minimum of 28.6GB of information down from the observatory, twice a day.”
📞 Howdy Webb? It's us, Earth!

On Tuesday, December 28, some of the difficult deployment phases will start. It entails the large sunshield, described as the scale of a tennis courtroom and requiring a slew of motors to push it into place. It should take 5 days for the sunshield to completely unfurl, and no, we doubt the Webb crew will likely be getting a lot sleep throughout this important course of.
Assuming the sunshield efficiently unfurls, Webb will then be ready to deploy the secondary mirror and the instrument radiator in early January.
13 days after launch comes one other step that’s possible to present crew members and Webb followers a couple of extra sleepless nights — the deployment of the 21-foot-wide golden mirror that’s central to its mission.
The process entails the locking into place of two wings of mirrors, every one holding three of your complete mirror’s 18 segments. Profitable completion of this stage will mark the telescope’s full deployment.
Webb will then spend a pair extra weeks touring to its vacation spot orbit at a degree generally known as L2, about 4 occasions the space between Earth and the moon. Over the next 5 months the mirror’s alignment will likely be fine-tuned and the telescope’s devices calibrated.
After which the enjoyable begins.
