I have read in other discussions that the contractor has great confidence in the deployment of the sun shield because of their experience with similar systems on classified satellites. I think as long as the launch is successful there won’t be any problems with the mission.
- CydeWeys 7y agoI really hope this is true, but there must still be something different, because there's been years of delay caused by the solar shade not deploying properly.
- ttul 7y agoIndeed. The NRO - rumor has it - has been launching satellites to observe the earth in the infrared for years..
- petschge 7y agoSince you are looking at a warm planet you will never get your camera down to 7 K nor do you need to as all sources are close by and bright compared to the astronomical targets for JWST. So the shielding issue is somewhat different. Having Earth, Moon and Sun in the same direction so you can block all of them with a single heat shield is actually one of the reasons why JWST is going to the L2 Lagrange point.
- CyanBird 7y agoThis is a good take, I like it, the US has deployed tons of spy satellites, and if they think the sail/shield+Mirrors will deploy well because they have used it in spy satellites before then I'll believe it
