Plammox writes: Last year, non-profit, voluntary-based Copenhagen Suborbitals failed at launching what they call the world's largest amateur rocket, because of a frozen LOX-valve. This year, the sea launch platform "Sputnik" has become self-propelled, eliminating the need for their home-built submarine(!). Sputnik is on its way into the Baltic Sea right now and a launch attempt is expected on Friday. However, one of the founders warns that even if ignition should occur, it might very well look like this.
