Structure
Structure of Hubble & James Webb Space Telescopes
Hubble operates in low Earth orbit with a 2.4-meter primary mirror and instruments spanning ultraviolet through near-infrared wavelengths. Webb uses a 6.5-meter segmented mirror, cryogenic near- and mid-infrared instruments, a large sunshield, and a halo orbit near the Sun-Earth L2 region.
