Getting off the rock which we’re gravitationally bound to is an expensive endeavor, so much so that doing it has well been out of the reach of anyone but the super-governments of the world for almost half a century. We’re in the middle of a space revolution with private companies popping up everywhere promising to reduce the cost of access to space with many of them delivering on their promises. Still even with so many revolutions happening in the private space industry the cost of doing so is still well out of the reach of the vast majority of people in the world, even though they’ve come down by an order of magnitude in the past decade.
Still there are people working on extremely novel solutions to this problem and they’re starting to show some very promising results. Late last year I wrote about Copenhagen Suborbitals a volunteer team that is working on a single person rocket using only donated funds. Back then they were gearing up to launch their first test rocket called HEAT from their sea launch platform that was propelled by a submarine that one of its creators built. Unfortunately they did not manage to launch as the cryogenic valve for the liquefied oxygen had frozen shut (thanks to the hair dryer they used as a heater draining the batteries on the sub) preventing the rocket from igniting. They were determined to launch it however and just recently they gave it another attempt.
The upgraded rocket, dubbed HEAT-1X, has a few improvements over its previous incarnation. The sea launch platform is now a fully enclosed unit, no longer requiring external propulsion from a submarine to get it into position. HEAT-1X now uses a polyurethane rubber mix instead of the previously used paraffin wax which was found to not vaporize completely which caused a reduction in the resulting amount of thrust. With these improvements in mind they attempted launching again back on the 3rd of June, and the results speak for themselves:
The launch, whilst undoubtedly a success for all involved, wasn’t without its share of problems. HEAT-1X did manage to achieve supersonic speed however it deviated from its direct vertical flight path considerably. Even though they were out in the ocean mission control decided to shut down the engine after 21 seconds of flight. The craft still managed to achieve a height of approximately 2.8KM in that time and covered over 8KM in ground distance. There was successful separation of the booster and craft stages however the parachute on the booster was torn free due to the high drag it experienced. The space craft’s parachutes didn’t unfurl properly either causing it to receive significant damage upon landing. Unfortunately the booster was lost to the Baltic Sea but the capsule was recovered successfully.
Despite those problems the HEAT-1X flight represents a tremendous step forward for the Copenhagen Suborbitals team and shows that they are quite capable of building a craft capable of delivering people into suborbital space. They’re still a long way from putting a person in one of their crafts (3~5 years is their estimate) but this launch validates much of the work they have done to this point. I really can’t wait to see them achieve their vision of getting someone into space on a shoestring budget and should they succeed they will make Denmark the fourth nation ever to launch a man into space (Russia, USA and China were ahead of them, if you were wondering). Considering that it will all be done with volunteer time and donations make the achievement even more incredible and I’m sure they’re inspiring many of their younger Danes to pursue a life in the sciences and engineering.
