Summary

The ONEWEB-0191 satellite, also known as OneWeb SL0191, was launched on April 25, 2021, from the Vostochny Cosmodrome Launch Pad PU1S using a Soyuz-2-1B launch vehicle. It belongs to the UK-based Oneweb constellation and is part of the ARROW bus series manufactured by ONEWUS. The satellite measures 1.3 meters in length with a diameter of 1 meter and a span of 5 meters, carrying a Ku-Band payload for communication purposes. Its dry mass is 140 kg, and it was launched with a total mass of 148 kg. It uses solar arrays and batteries for power and employs SPT-50 or BHT-350 Hall effect thrusters as its propulsion system. The mission lifetime is projected to be around seven years.

The Satellite That Found 22 Photons and Changed Astronomy

On April 27, 1961, a Scout rocket lifted a 37-kilogram NASA satellite into orbit from Wallops Island carrying the first serious instrument for detecting cosmic gamma rays.

In that time it registered 22 gamma-ray photons - a pitiful number by modern standards, but enough to launch an entire branch of astronomy.
