Summary
The ONEWEB-0143 satellite, also known as OneWeb SL0144, is a communication satellite built by ONEWUS for the UK-based company OneWeb. Launched on December 18, 2020, from VOSTO using a Soyuz-2-1B launch vehicle, it employs an Arrow bus configuration with dimensions of 1.3 meters in length and 1 meter in diameter, extending to a span of 5 meters when deployed. The satellite has a dry mass of 140 kg and a total launch mass of 148 kg. It is equipped with a Ku-Band payload for communication purposes and uses solar arrays and batteries for power generation. Its propulsion system consists of SPT-50 or BHT-350 Hall effect thrusters, while its shape resembles a trapezoid with two panels. The satellite's expected operational lifetime is 7 years.
