![]() ![]() ![]() It will also need to propel itself occasionally to counteract the effects of solar radiation pressure on the telescope's large sunshield. The JWST will need minor adjustments over time to remain in orbit. The team worked hard to preserve as much fuel as possible for use over the lifetime of Webb. The final course corrections added only about 1.6 meters per second (3.6 miles per hour) to Webb's pace, slowly moving it into orbit around L2. Webb's final orbit allows it an expansive view of the cosmos 'at any given moment' and ensures the onboard instruments stay cold enough to perform 'optimal science.' Webb has been making minor course corrections since its launch. If you'd like to learn more about the space telescope and its instruments, check out the video below from longtime DPReview reader Dr. The telescope's cameras can see further into the past and across more wavelengths than Hubble, so we should see even more incredible photographs and learn much more about how the first galaxies formed when Webb commences its full operations in a few months. The James Webb Space Telescope includes four onboard cameras, including the NIRCam, NIRSpec, NIRISS and MIRI. On January 19, Webb finished deploying the 18 segments that comprise its primary mirror. Webb has spent the past month working its way to L2 while unfolding its sunshield and other components. The primary mirror segments and secondary mirror have been deployed from their launch positions, so engineers are now amidst a three-month process of aligning the telescope's sophisticated optics to 'nearly nanometer precision.' Yes, unfortunately, 'this summer' hints at the fact that Webb has more work to do before it can start capturing and beaming images back to Earth. And I can't wait to see Webb's first new views of the universe this summer!' We're one step closer to uncovering the mysteries of the universe. 'Congratulations to the team for all of their hard work ensuring Webb's safe arrival at L2 today. 'Webb, welcome home!' said NASA Administrator Bill Nelson. James Webb Space Telescope trajectory map. It's also a big deal for everyone else, as JWST will join the Hubble Space Telescope in our pursuit for more knowledge about our universe and its origins. The $10B project has been decades in the making, so its arrival at L2 is a truly momentous occasion for all involved. This Monday, nearly a month later, Webb, as NASA often refers to it, reached its final orbit around the second Sun-Earth Lagrange point, or L2, about 1.5 million kilometers (nearly 1 million miles) from Earth.Įngineers and researchers have been working on the incredible space telescope since the 1990s. If you want to see the launch, watch a replay of the live stream here. NASA's James Webb Space Telescope lifted off on Christmas morning from Arianespace's ELA-3 launch complex at Europe's Spaceport in French Guiana.
