From that video it appears the unfolding sequence is set to occur prior to the insertion burn into L2.
If the JWST will in fact spend almost a month in earth's orbit, does someone have an educated estimate on the magnitude of risk posed by space junk to nominal deployment?
Looking at those solar shields I imagine that they could be destroyed entirely by even the smallest of debris fragments. Same with the mirrors.
Edit: I'm wrong here (thanks @thethirdone). The burn set to occur after deployment is the L2 insertion burn and not the transfer insertion burn. Most of deployment will occur in the transfer orbit en route to L2, far away from earth-orbiting debris.
- 0x0nyandesu 5y agoBasically none cause it's outside the typical orbit
- ProjectArcturis 5y agoIt will orbit and deploy at the point where the Earth's and sun's gravity cancel out, which is far beyond most anything else, especially space junk.
- thethirdone 5y agoI interpreted "orbital insertion burn" to mean the stabilization into L2 burn. With that interpretation the unfolding occurs during its travel to L2 where there is little space debris.
