NASA to launch COSI telescope to search for antimatter in 2025

The launch of the COSI gamma-ray space telescope is scheduled for 2025.

Its task is to search for soft gamma rays with

intensity from 0.2 to 5 MeV (millionselectron-vol). Gamma-ray bursts with such energy appear during the annihilation of positrons and electrons, as well as during the synthesis of elements or nucleosynthesis and during the formation of heavy elements during supernova explosions.

NASA will send COSI to study these phenomena in the Galaxy in order to understand and study the physical processes in the Universe.

The cost of development COSI  is from $145 million.Scientists from the University of California at Berkeley will supervise the work. Previously, in 2016, employees of this university lifted a prototype telescope in a balloon into the stratosphere to test its operation. 

In 2025, the gamma-ray telescope will be launched into low Earth orbit, after which it will begin its work on data transmission.
