Webb29 aug. 2024 · 12. The JWST is not enclosed in a tube because it would be too big for launch otherwise. The primary mirror is too large for existing launch vehicles, so the mirror is composed of 18 hexagonal segments, which will unfold after the telescope is launched. If the primary mirror is too large for launch, the enclosing tube would be too large also.
