index-tech-science-James Webb's eyes are beginning to open

NASA engineers started on Christmas The focus of the James Webb Space Telescope (JWST) was launched, Later Successfully opened the space telescope on their main. It would take months to align the elements of the eighteen-segment, rugged mirror into a single large telescope, the space agency said.

As a first step, the engineers activated 126 small actuators (mini-actuators) with which they wanted to adjust the primary mirror, and then activated six more pieces for the secondary mirror. The latter will now be responsible for verifying that the primary work sequence is complete and will subsequently collect the reflected light from the primary mirror, thus contributing to the observatory’s planned operation. During the process, members of the control team also observed the actuators operating at minus 240 °C to control the JWST steering mirror, which would play a role in the image stabilization process at a later date.

NASA is waiting Goddard Orkozpontjaban The ground control is that it will take ten days for the mirrors to turn from the starting direction. Currently, the eighteen hexagonal segments that make up the mirror are still on the fasteners that held them in place at startup. They need to move a centimeter before they come together into a single, monolithic light-collecting surface. Guardianneck Lee Feinberg, director of battery management at JWST’s optical telescope, expects to complete the work in three months with “five-thousandths of the thickness of a human hair.”

The Webb Space Telescope is still at the L2 Lagrange point, one and a half million kilometers from Earth, which will be its parking lot and workplace. The next step will take place on 23 January, with the spacecraft’s engines due to start arriving at L2. Once on the track, the L2 point will be circled in about a year and a half.

The JWST mirror is 6.5 meters in diameter and has a brightness of F/ 20.2 and the focal length is 131.4 m. It detects the orange, red to mid-infrared range visible to the human eye, collecting photons in the range of 600 nanometers to 28.3 micrometers. During the planned life of the observatory for ten years they hope, it manages to revolutionize astronomy and astrophysics on the same level as the Hubble Space Telescope in the 1990s.
