James Webb Space Telescope Getting Closer to Being TestedMd Noman Siddique (Author) Published Date : Feb 08, 2016 21:15 IST
The test phase of the James Webb Space Telescope is inching closer to reality as the last gold clad mirror segment has been installed. The 18th and the last primary mirror segment finalized one more of the construction phases.
The largest space telescope anywhere in the world, therefore, is closer to its scheduled launch of October 2018 programmed by NASA.
The telescope is a project that by most is considered ambitious that is designed as being the successor to the world-famous Hubble Space Telescope.
While the Hubble has taken credit for an array of different discoveries, in just a few years, the new James Webb Space Telescope will take to the stage and be the new tool to see far into the universe.
Installing the 18th and last 88-pound gold-clad primary mirror segment was made easier by using a robotic arm.
The costs for the successor to the Hubble have now reached more than $8.8 billion. Nonetheless, the new telescope is the latest massive step forward for science.
The new telescope will be optimized completely to work at the infrared spectrum. In contrast, Hubble is only able to capture images in the visible light spectrum.
The mission of the two telescopes is all the same at the core of each: looking deep into the heart of the formation of the universe.
However, each of the instruments has a different route it takes to reach the same goal.
Gaining new knowledge each day on how the chemistry in the universe is switched from one heated, dense mass to the array of planets, starts, galaxies and systems has been the mission of humanity for millennia.
In comparison with the current tool the Hubble, the new James Webb telescope features a light collecting surface that is much larger. The primary mirror surface is 21.3 feet in width. The secondary optics gear will be installed soon as the test phase inches closer.
