Radiation tolerant S-A2300 AI supercomputer completes LEO mission testing with successful results
Saturday, 01 November 2025 02:28
Aitech Systems has conducted radiation testing for the S-A2300 AI supercomputer to determine its suitability for low Earth orbit missions. On May 6, 2025, the S-A2300 underwent gamma irradiation using cobalt-60 at a specialized facility. The evaluation followed MIL-STD-883 guidelines, exposing the unit to dose rates of 2815 rad per minute at ambient temperature while powered and connected to tes ALMA achieves unprecedented cosmic microwave background temperature measurement at redshift 0.89
