The James Webb Telescope, heading to the destination of 15.00,000 kilometers away from the earth, reaching the main milestone because it crosses the height of the moon when the engineers do second burns. The correction of the middle correction was carried out 60 hours after the telescope was launched from the French Guiana lasting for 9 minutes and 27 seconds, placing the telescope precisely in the orbit around the second lagging point.
NASA said that the total three corrections of the Middle Course (MCC) maneuvered need to be carried out to harmonize the spacecraft for the intended purpose, with two finished, the third is set for 29 days after the launch will be optimal orbiting around L2. “It burns the Fine-Tunes webb track after launch. The duration of the burn will depend on the performance of Ariane 5 Launcher,” NASA said.
While both burns are finished, the telescope still has more than 27 days of traveling in front of himself to reach a distance of 15.00,000 kilometers from Earth. Many still need to occur with the accuracy of pinpoint to ensure the telescope starts its mission to view the birth of our universe.
What’s next for James Webb Telescope?
The scientific engineering and miracle of his time, mobilizing James Webb telescope in space will be one of the most challenging achievements that humans have done. Mike Menzel, Engineer Tin System Mission Webb said, “There is no second chance, we have 300 items of one point failure and they all have to work properly, when you are a million miles away from the earth, you cannot send someone to fix it. We never Put the telescope so far from us and everything must be true. “
With two course corrections, the next effort is to spread the sun on the telescope, which will protect the instruments from the heat produced by the sun, the moon and the earth. Placement began three days after being launched when scientists lowered the Sun-Shield and enhancing the main mirror and instrument from it. With solar wind pushing a spacecraft, the turn tab will be deployed to remain stable.
Sunshield is far more complicated, consisting of five shields about three tennis courts from Kapton material which is very thin about one to two thousand with thick inches. That alone includes 140 release mechanisms, 70 assembly hinges, eight motorbike deployments, bearings, springs, gears, 400 pull, and a total cable of 1312 feet. All must work perfectly.
The engineer will send an order to release the restraint that protects the telescope during the launch, then the cover in the core area is deleted. All 107 Sunshield release mechanisms need to shoot on a signal for shields to be fully open. That’s 107.
Open the Origami mirror
When scientists first conceptualize the telescope, the biggest challenge is precisely in the biggest rocket vortex which is only 5.4 meters wide. The mirror in the telescope must be folded like Origami for it even launched in the first place. Now in space, the mirror will begin to be used by day 10 with an open secondary mirror. This will be followed up by the main mirror that appears on the 12th day since it was launched.
However, after all this and almost 27 days slid through open space, Webb will still be ready to do science. While the instrument cools, the motor control behind each of the 18 webb mirror segments, secondary mirror and the steering mirror located inside the primary mirror must align to form a perfect mirror on the 29th day.
