How the James Webb Space Telescope Works HowStuffWorks

+

09/10/2014· A highgain antenna adorns the Webb''s exterior, as do a set of star trackers that work with the fine guidance sensor to keep everything pointed in the right direction. Finally, at one end of the sunshield, and perpendicular to it, is a momentum trim tab that offsets the pressure that photons exert on the ship, much like a trim flap does on a sailing ship.

+

02/11/2021· Re: NASA James Webb Space Telescope Discussion and Updates Thread 2. Ignoring the fact that webb won''t be in earth orbit, it''s unrefuelable. The maneuvering thrusters of an approaching craft would destroy the sunshield. These are real problems, but not insurmountable. Refueling is already designed to work in GEO.

James Webb Space Telescope Thermal Pathfinder Test Results TDL

+

The James Webb Space Telescope (JWST), scheduled for launch in 2018, includes a 6m primary mirror passively cooled below 55 Kelvin. The observatory cannot be optically or thermally tested as a system at flight temperatures due to its large sunshield, so the telescope portion along with its instrument complement will be tested as a single unit. This test is scheduled for 2017, …
