Copenhagen Suborbitals dixit:
“…we will show you some of the preparations during March. You will see:
– the development of our pressure regulator for pressurizing tanks.
– the electronics group at work.
– a parachute test from the 100-meter high gantry crane at Odense Steel shipyard.
– the latest development of the spaceship Tycho Deep Space, now with buoyacy balloons.
– ablative coating casting in the second stage of the two-stage rocket Smaragd.
– the moving of our MVAB, so we may continue our work to make the floating launch pad Sputnik ready to sail.
– the renovation of the submarine Nautilus.
And then Peter Madsen was at the Planetarium in Copenhagen to live blog with those of our support members who dropped by. However, first a little about our large liquid engine TM65.”
