NASA’s Webb Space Telescope’s latest test photo exposure, will officially begin space missions in July

Reporter Archer Sun / Comprehensive Report

NASA recently stated on its official blog that the Webb Space Telescope, which has spent more than $10 billion, has completed the proofreading of the Mid-Infrared Instrument (MIRI). Compared with the Spitzer Space Telescope, the Webb Space Telescope is significantly clearer, and the space mission is expected to begin in mid-July this year.

Webb Space Telescope takes test images with 7.7-micron MIRI, and it works pretty well

From the Webb Space Telescope and the retired Spitzer Space Telescope, after comparing the images of the same Large Magellanic Cloud satellite galaxy, it was found that there is a significant difference in image quality, because the former uses 7.7-micron MIRI, and the latter uses 7.7 micron MIRI. Because of 8.0 microns, NASA used the Large Magellanic Cloud as a test because it has a fairly dense star field for easy identification of shooting effects.

A careful analysis of the test images taken by the Webb Space Telescope reveals the polycyclic aromatic hydrocarbons (Polycyclic aromatic hydrocarbons), which are aromatic hydrocarbons that contain known or potential carcinogens from sources like It is industrial pollution from incinerators and other incomplete combustion or thermal cracking. In addition, the emission of carbon and hydrogen molecules can also be found in the image, which play an important role in thermal balance and chemical reactions, and these data help astronomers to better understand how protoplanets and star systems are born.

NASA scientists and engineers will continue to calibrate the Webb Space Telescope’s four scientific instruments (including 18 hexagonal telescope lenses) in the next two months to collect different test images and apertures to verify 17 different Operation mode, a total of more than 1200 tests have now been completed about 1000 items, each instrument has at least 4 to 5 modes to be tested, very complex.
