A Nasa announced which this Thursday (6), around 10:48 am, carried out the implantation of a radiator of heat specialist, necessary for the Scientific instruments of the Webb Space Telescope to reach and maintain the low temperatures necessary for its operation.
THE Aft Deployable Instrument Radiator (ADIR), is a large, rectangular 1.2 by 2.4 meter panel consisting of high-purity aluminum sub-panels covered in painted honeycomb cells to create a ultra negra.

ADIR, which is installed on the back of the telescope, is hinged like a hinged trapdoor, and is connected to the instruments via flexible strips made of high-purity aluminum foil. The radiator takes heat from the instruments and dumps it into deep space.
The ADIR deployment took about 15 minutes. The final series of large deployments of Webb is planned to begin this Friday, January 7th, with the rotation of the first of the two wings of the primary mirror to its final position. The rotation of the second wing of the primary mirror, the last of the major operations in mounting the telescope, is planned for Saturday, January 8.

Launched by a rocket Ariane 5, by the European consortium Arianespace, on December 25, the James Webb is the most expensive project in NASA’s history, with a total cost estimated at more than BRL 56 billion.
Seen as a “successor” to the Hubble, it is equipped with a suite of advanced, and delicate, instruments capable of observing the universe in the infrared light spectrum and will be able to “see” events that happened 13.5 billion years ago. In addition, it is able to analyze and characterize the composition of the atmosphere of exoplanets, which is crucial for our search for life beyond Earth.
