The thing about telescopes is that bigger is always better, and bigger is always more expensive. 10 small telescopes will do less useful science than one large telescope. The optical capabilities of a telescope are a function of the mirror diameter.
- cedilla 5y agoThat isn't always true, for longer wavelength in particular it's very feasible to use many smaller telescopes with interferometry to reach effective aperture sizes we could never reach with a single telescope. However in regards to JWT I expect that a lot of its missions will collect miniscule amounts of light, making interferometry infeasible.
