Summary
[edit]| Description |
To observe objects in the distant cosmos, and to do science that’s never been done before, technicians and engineers needed to rethink space telescope design. The James Webb Space Telescope is the first of its kind “open” style telescope that relies on innovative space shielding to block unwanted light from reaching its sensitive instruments. NASA’s James Webb Space Telescope's scientific instruments need to be cooled down to a temperature so cold, it would freeze the oxygen in Earth’s atmosphere solid. Intentionally chilling the telescope mirrors and instruments with innovative technologies and intelligent spacecraft design allows them to be far more sensitive to faint infrared light. Infrared can be described simply as heat, and if Webb’s components are cool, they are far more capable at observing faint heat signatures from the distant universe. Shown here: Northrop Grumman technician Ricardo Pantoja performs a routine inspection of NASA Webb’s innovative blanketing along the connection point of its deployable primary mirror segments.
