Summary
The ONEWEB-0210 satellite, also known as OneWeb SL0210, is a communication satellite built by ONEWUS and operated by ONEWEBN for the UK. It was launched on May 28, 2021, from the Vostochny Cosmodrome using a Soyuz-2-1B launch vehicle. The satellite has an Arrow bus configuration with dimensions of 1.3 meters in length, 1 meter in diameter, and a span of 5 meters when deployed. It weighs approximately 140 kilograms dry and had a launch mass of 148 kilograms. Equipped with a Ku-Band payload for communication purposes, the satellite is powered by solar arrays and batteries. The propulsion system uses either SPT-50 or BHT-350 Hall effect thrusters to maintain its orbit. This satellite has an expected operational lifetime of about seven years.
