Leveraging Common Technology and Programming for Amateur Spaceflight
summary
Copenhagen Suborbitals aims to put a human above the 100 km Kármán line using low-cost, common tech and iteration. Past flights include 2011 HEAT-1X and NEX rockets; one test shows a 10 cm crack that ejects 600 L fuel spill and destroys an engine, another cuts out at ~1.2 km from LOX pressure/mixture issues plus a parachute state-machine bug. Guidance moves from $20 MEMS to Analog Devices IMU units (~$3–5k), sea launches from ESD 139 sea launches, rebuilt fishing vessels, custom live video using snowX streaming stack. Upcoming NEX-class North Sea launch next summer.
