JWST Development Hurdles
- The James Webb Space Telescope (JWST) project faced significant challenges, including Congressional cancellation and technological limitations.
- The team persevered, inventing 10 new technologies and securing renewed funding to bring the project to fruition.
JWST's Strategic Location
- The JWST's location a million miles away at the second Lagrange point allows continuous observation and keeps it cold for infrared astronomy.
- The efficient launch and orbit insertion give the telescope an expected operational lifespan of over 20 years.
JWST's Origami Deployment
- Unlike Hubble, the JWST launched folded like origami and underwent a complex two-week deployment process in space.
- The deployment involved 300 single-point failures, highlighting the mission's engineering complexity and risk.
