SSTOs have long been a dream because they are fully reusable and are able to take off and land horizontally from a traditional runway and so make the cost of reaching orbit very much cheaper - estimated at better than a 20th of current levels.
That makes SSTOs a game-changer for taking astronauts into space, for deploying satellites and space probes, as well as for reducing time in conventional air travel.
This was the first SSTO mission for ILS Proton and it provided an additional 200 kg of performance for this mission.
