Super exiting. - JWST costs ̃$8.8B USD, about the same as aircraft carrier, or Large Hadron Collider and it goes into a rocket! - JWST has 344 single-point-of-failures, 80% of them related to deployment. Mars landers have significantly less If I remember correctly. If each single-point failure has 0.0001 failure probability, the mission fails with 3.4% probability. If each single-point failure has 0.0002 failure probability, the mission fails with 6.6% probability.
