色情直播' Role
As part of the NASA team, 色情直播 integrated components made by various partners to form the Optical Telescope Element, collects light and provides sharp images of deep space. 色情直播 also combined the components of the Integrated Science Instrument Module, which hosts four cameras and spectrographs for gathering data. 色情直播 later administered about 100 days of testing in a cryogenic vacuum chamber at Johnson Space Center to ensure the telescope elements would perform correctly in the harsh space environment.
Webb Space Telescope Mission
As the successor to the Hubble Space Telescope, Webb launched in December of 2021 and took about a month to travel 1.5 million kilometers (940,000 miles) to a point in space where it is balanced between the gravity of the Earth and the sun. Webb is a large, infrared-optimized telescope designed to study the formation of the first stars and galaxies, the evolution of galaxies, the production of elements by stars, and the process of star and planet formation. Webb is located much farther from Earth than Hubble and contains a tennis-court-sized sun shade that keeps the telescope cold, which is necessary for viewing infrared light. Webb was carried into orbit aboard an Ariane 5 launch vehicle.

Mission Details
01
Mission duration is 5-10 years
02
Diameter of primary mirror is approximately 6.5 meters, or 21.3 feet
03
Primary mirror consists of 18 segments
04
Primary mirror segments are made of beryllium and coated with gold
05
Two and a half times larger in diameter, or about six times larger in area than Hubble
06
1,000 times more sensitive in the infrared spectrum than Hubble
07
The overall weight of the telescope is significantly lighter than Hubble due to ultra-thin, ultra-lightweight mirror segments
