The 1.8-metre-long spacecraft will be transported to an altitude of 340 kilometres by a two-stage rocket. After leaving the atmosphere, the scramjet vehicle will separate from the rocket, and orient itself for the re-entry with small thrusters.

During the return flight, the vehicle will be accelerated by gravity to Mach 8 – about 8600 kilometres per hour.

The part of the experiment important to the scientists takes place at an altitude of between 27 and 32 kilometres. This is where the scramjet's hydrogen fuel will be injected, and a wide range of instruments will analyse the combustion and measure thrust
