The James Webb Space Telescope is halfway through its instrument checks

The James Webb Space Telescope is halfway through verifying its instrument modes for science operations, which are expected to begin in mid-July.

The James Webb Space Telescope is equipped with four state-of-the-art instruments, which will allow the $10 billion observatory to see the most distant and oldest galaxies, which formed in the early universe a few hundred million only years after the Big Bang, and to study their chemical composition. These instruments have 17 science modes between them, and each science mode must be tested before the telescope can begin science operations in mid-July.
