10-100 times cheaper. An LBT night is around $50k-100k, which over 10 years corresponds to $300 millions. JWST total budget is about $10 billions.
True, JWST can operate close to 24/7. On the other hand, land-based telescopes are under constant refurbishment and upgrades, and they become more powerful over time.
- shiroiushi 2y agoSure, but you're comparing apples and oranges. It's like comparing a sports car to a boat. A ground-based telescope can never do what the JWST can do, because of the atmosphere (namely, do IR photography).
