Why would it take large thrust. Low thrust over more time should do as
well.

I wonder if they considered deploying the sun shield in low Earth
orbit, where it could be repaired and then boosting off to the
Lagrange-2 point?

Two weeks from Wednesday the long delayed 10 billion dollar James
Webb telescope will finally be launched that could revolutionize
our understanding of the universe; because native Hawaiian
barbarians destroyed the 30 meter telescope which should've
become operational several years ago but now never will, Web will
be the first of a new generation of huge super sophisticated
observatories. But I've got my fingers crossed, and the terror
won't stop with a successful launch but will continue for the
next 29 days. I'm especially worried about the delicate 5 layered
70 foot by 47 foot sunshield required to keep the telescope cold
so it can detect the infrared light it was designed to find.
Something that big obviously can't fit into the nosecone of a
rocket so it must be tightly folded up origami style and be
unfurled in space, but to do that 8 motors, 140 actuators, 150
latches, and 400 pulleys must behave exactly as they were
designed to and do so in precise synchronization or the sunshield
will tear and the entire project will fail. And, because it will
not be in low earth orbit but at the Lagrange-2 point more than
900,000 miles from Earth, there is no possibility of an astronaut
repair mission as happened with the Hubble telescope if something
goes wrong. After 29 days the major dangers will be behind us but
it will still take another 5 months for the telescope to cool
down and be properly aligned before it can start doing any science.
