Scheduled for launch in 2027, the Nancy Grace Roman Telescope is slowly being readied for operation. This week, NASA announced that they have started to joined the mission’s telescope, instrument carrier and instruments onto the spacecraft. Having completed the construction, they will now move to the testing phase where the instrument will be subjected to more tests. These will include exposure to electromagnetic radiation expected during launch along with vibration and thermal changes too. If it passes these tests, the new space telescope will be on the home straight.
