The world’s leading space laboratory has successfully completed several important steps to refurbish its 18 gold glass parts. The telescope team, which checked this milestone from Webb’s list, expects the lab to exceed its targets.
On March 11, Webb completed the “Fine Facing”, an important step in ensuring that Webb’s optical capabilities work. During the experiments, the team encountered no problems and determined that the web could monitor light from distant objects and provide that light to scientific instruments in the laboratory.
For testing, the web focused on the star 2MASS J17554042 + 6551277. A red filter was used to show contrast. Webb’s observation capabilities are very sensitive, with individual galaxies and stars being seen behind the star in the image.
Marshall Perrin, a web-based telescope scientist at the Space Telescope Science Institute in Baltimore, said: “The laws of physics focus images together as much as they can.” The galaxies could not be seen. “
Although the first high-resolution images collected by the Web at the Cosmos were not expected until the end of June, new experimental images released by NASA on Wednesday show that the Web can use individual parts of its glass as a giant 21-foot, 4. -Catch light from an inch (6.5-meter) glass and a star.
“The engineering images we see today are as sharp and crisp as those taken by Hubble, but they are at a wavelength of light that is completely invisible to humans, so it makes the invisible universe a very sharp focal point.” Said scientist Jane Rigby.
“Twenty years ago, the Web team began to build the most powerful telescope anyone could ever have in space and came up with a bold optical design to achieve the scientific goals they sought,” said Thomas Jurbusen, co – executive of NASA’s science movement. Directorate in Washington. “Today we can say that the design is going to deliver.”
While the process is ongoing, the team is encouraged to see the web perform better than expected. Now that the elegant phase is over, the near-infrared camera, which acts as the telescope’s primary imager, has been aligned with the glass.
Webb also focused on capturing images of real glass areas using a new “selfie” lens. The selfie shows the alignment of the glass parts while holding the starlight uniformly.
Having completed the elegant phase and all the important steps that preceded it, the team breathes a sigh of relief.
“The sleepless nights I experienced and all the worries I experienced, they are all behind us now,” Surbusen said. “There is still a mountain to climb, but we are climbing that mountain now.”
For the next two months, the team will complete the final steps of the alignment process and ensure that all scientific instruments are calibrated.
“We are at the point where we thought we would be at this point three months after loading, and that completes the rest of the commissioning within six months of its launch and sets us on the path to a transition to science starting this summer,” Berin said.
Once the web is fully operational, it will “move into the most demanding year of scientific activity,” Rigby said.
