Another step closer to launch

ICON passes pre-environmental review

After passing its "Pre-Environmental Review” last week, the ICON spacecraft/observatory is now in environmental testing at Orbital ATK in Gilbert, AZ. We will run a number of tests over the following weeks  -- such as vibration and acoustical tests -- that will simulate the launch and space environments that ICON will be exposed to. All the instruments continue to check out well, and we’re getting a lot of time on the observatory. All this testing and reviewing shows us that ICON is in great shape and will be ready to go when launch day arrives this summer. It’s all coming together!
