H2Sat (Heinrich Hertz) to fly on Ariane 5 – while Arianespace looks ahead to a different propellant combination

by | Dec 15, 2017 | commercial launch services, Launches, Satellites

The German Aerospace Centre DLR has formally selected the Arianespace Ariane 5 launch vehicle to launch its experimental communications satellite H2Sat (Heinrich Hertz) – also known as the Heinrich Hertzsat – in 2021 or 2022.

In a separate development Arianespace owner ArianeGroup has ordered the development of the Prometheus engine which uses the oxygen (LOx) and methane propellant combination. This is a precursor to a new series of low cost engines which would replace the liquid Hydrogen/LOx engine and solid rocket technologies currently used by the Ariane 5.
