HEAT-2X

Hybrid Exo Atmospheric Transporter 2X

Mission Profile

The HEAT-2X (Hybrid Exo Atmospheric Transporter 2X) is a single-stage sounding rocket developed by Copenhagen Suborbitals, a Danish volunteer-run organization pursuing open-source crewed spaceflight on a shoestring budget. First flown in August 2014, it was designed as a propulsion and altitude testbed on the path toward a human-capable launch vehicle. The HEAT-2X represents the remarkable achievement of citizen engineers advancing rocket technology entirely outside traditional government or commercial frameworks.
