BEACON TRANSCRIPT – It would seem that the Hubble Space Telescope will soon be replaced by yet another example of fine engineering. In a recent statement, NASA declared that the James Webb Space Telescope received its last mirror, meaning that the device is only steps away from being ready.
In a recent press statement, the North American Space agency announced that the technician working on the James Webb Telescope project have finished assembling the primary mirror of the gigantic telescope. According to the NASA, the James Webb telescope is by far the biggest telescope devised by mankind, and that it will be used to gaze ever farther into space.
According to the space agency, the technicians finished the job of putting together the telescope’s primary mirror on Wednesday afternoon. Making use of a state-of-the-art robotic arm, the technicians managed to fit in the last section of the telescope’s primary mirror.
The telescope’s primary mirror encompasses no less than 18 segments, each of them being roughly the size of a coffee table. Also, these segments have a hexagonal shape and weight approximately 80 pounds. With the hexagonal segment in place, the soon-to-be-launched space gazer measures approximately 21 feet in diameter.
If all tests show green, the massive telescope, which is roughly the size of a football field, will be deployed in October 2018.
The football field-sized telescope will be employed to study high-redshift galaxies and to conduct further research on dusk disks. Basically, all the investigations will be conducted using Webb’s onboard near-infrared spectrometer, a device used to analyze radiation emitted from various celestial objects. It would seem that most of these radiations are emitted at an infrared wavelength.
The James Webb Space Telescope received its last mirror on Wednesday, and all tests conducted on the massive star gazer showed green. As stated, the telescope’s gargantuan mirror measures no less than 6.5 meters in diameter. Moreover, the primary mirror is made from beryllium coated in gold.
Furthermore, in order to be capable of making precise observations, the primary body of the telescope must be shielded from high temperatures. The scientists working on the project stated that the telescope’s chassis must be kept quite cold, outside hull temperature must be under -220 degrees Celsius all the time. If the temperature goes up, the infrared radiation emitted from the telescope will overwhelm the instruments found inside.
For this purpose, the engineers designed a special sunshield which will be able to cool down the telescope and also prevent outside radiation from tampering with its instruments.
