Today, at 2:00 pm Eastern Standard Time, Webb fired the onboard thruster for about 5 minutes (297 seconds), completing the final post-launch. Course correction In the orbit of Webb.This midway modified combustion inserted the web towards the final orbit around it. Second Sun-Earth Lagrange Point, or L2Almost a million miles away from Earth.
Burning during the final course added about 3.6 mph (1.6 m / s) (just a walking pace) to Webb’s speed. This was all that was needed to send it into the preferred “halo” orbit around the L2 point.
“Welcome back, web!” NASA Administrator Bill Nelson. “Congratulations to all the teams that helped Webb reach L2 safely today. We are one step closer to unraveling the mysteries of the universe. And this summer, the first of Webb. I can’t wait to see a new view of the universe! “
Webb’s orbit allows for a wide field of view of the universe at any time, giving the telescope’s optics and scientific instruments the opportunity to cool enough to perform optimal science. While moving to the area of L2, Webb uses as little propellant as possible for course modification and leaves as much propellant as possible for normal operation of Webb: Stationkeeping (for Webb). (Small adjustments to keep it in orbit)) and momentum unloading (to counteract the effects of solar radiation pressure on huge awnings).
Bill Ox, Webb Project Manager at NASA’s Goddard Space Flight Center, said: “We are now approaching the beginning of mirror adjustments, equipment launches and test runs, and astounding and amazing discoveries.”
Now the Webb’s primary mirror segment and secondary mirror are Deployed From the launch position, engineers begin an advanced three-month process that adjusts the telescope’s optical system to near nanometer accuracy.
