Dellingr (GTOSat similar) [NASA]

GTOSat (Geostationary Transfer Orbit Satellite) is a 6U CubeSat mission developed by NASA's Goddard Space Flight Center to serve as a pathfinder for new radiation-tolerant technologies that could enable the deployment a constellation of small satellites beyond low-Earth orbit to gather simultaneous, multi-point measurements of Earth's ever-changing magnetosphere.

GTOSat will be the first CubeSat to operate in geostationary transfer orbit and the first to use the latest, more robust version of the NASA-developed Dellingr spacecraft bus called the Dellingr-X.

Launch is planned for early 2021, the USD 4.5-million GTOSat will gather measurements from a highly elliptical Earth orbit that is a standard transfer orbit for communications satellites operating in geostationary orbit about 38000 km from Earth. From that location, GTOSat will use its two onboard instruments to measure high-energy particles that likely originate from solar wind and cosmic rays.
