Construction is complete on the James Webb Space Telescope’s primary mirror

by • February 3, 2016 • No Comments

NASA engineers have been working tirelessly over the last few months, painstakingly building the James Webb Telescope‘s massive major mirror. This week marks a worthwhile milestone in the project, with the the last of the 18 individual segments now in place.

We initially heard confirmation that the assembly of the major mirror had begun when the initially segment was put in place at the end of November 2015, in a clean room at NASA’s Goddard Space Flight Center in Maryland. Since and so, 17 extra
segments have been put in place via a robot arm, with the construction phase finally accomplished on February 3, with the successful placement of the last piece.

Each panel of hexagonal-shaped mirror meacertains slightly over 4.2 ft (1.3 m) across, and weighs a few 88 lb (40 kg). Once deployed, all 18 segments can operate as a single. 21.4-ft (6.5-m) mirror, at that point the Hubble successor can get to work studying the formation of solar processs with the future to assist life, the evolution of our own solar process, and much additional.

Whilst the major mirror is now achieve, there’s a lot additional to do preceding the telescope’s scheduled commence in 2018, which include the construction of the secondary mirror, and different types of acoustic and vibration tests.

“Now that the mirror is achieve, we appear forward to installing the other optics and conducting tests on all the components to manufacture certain the telescope can endure a rocket commence,” said project manager Bill Ochs. “This is a excellent way to begin 2016!”
