The actual rocket development resulted in numerous successful tests of the solid fuel epoxy and the liquid oxidizer nitrous oxide, which was used in their hybrid rocket HATV (Hybrid Atmospheric Test Vehicle).
The HATV rocket was only 1/3 size of the final rocket, HEAT.
This HEAT rocket (Hybrid Exo Atmospheric Transporter) with liquid oxygen and polyurethane, would carry the MSC (the micro-spacecraft) above the 100 km boundary and into space.
The MSC was named after Tycho Brahe, and the combination was known as the HEAT-1X TYCHO BRAHE.

Gravity would then pull the MSC back to the atmosphere, where the MSC landed on water using parachutes.

The first HATV rocket was tested in a test stand on 8 March 2009.

Originally HEAT was to have been fueled with paraffin wax but a ground test 28 February 2010 revealed that some of the paraffin wax only partially melted, instead of evaporating.
The result was that HEAT-1X had less power than expected.
A ground test firing of HEAT-1X-P (P for polyurethane) was conducted 16 May 2010.

Stabilization of the rocket was by rollerons, a rather simple mechanism also used by missiles.
