Balloon flight success for budget von Brauns

The balloon was launched last Saturday from Churchill College, Cambridge. It contained enough helium to lift the payload and deliver 600g of excess lift. It rose at around five metres per second until reaching its peak altitude two hours after release. At this point, the balloon burst and the payload fell at a maximum velocity of 45m/s (100mph) before thicker atmosphere coupled to deployment of a 45cm parachute slowed it to a terminal velocity of 5.5m/s (12mph). Two hours and 46 minutes after taking to the skies, Nova 1 touched down a field near Great Livermore, north of Bury St Edmunds in Suffolk.

The team had been tracking the flight while giving chase in a car. Despite the loss of the data radio signal, "believed to be due to low temperature affecting the frequency of the crystal oscillator" and the failure of the antenna connection on the morse code receiver, the proto-von Brauns were able to eventually recover the payload after a post-touchdown text message from the onboard mobile phone revealed its precise location.

Project founder Carl Morland said: "This marks the first step in a series of flights to prove our tracking and telemetry systems. Once we can take a larger payload stably up to 30km, we will be in a position to launch a rocket from the balloon that will reach the 100 kilometre boundary of space for a tiny fraction of the present cost."

Next up for the Spaceflight team is analysis of the flight data and more work on lightening the payload. Carl Morland told El Reg that future launches would carry school science projects in the hope that direct involvement in the project would "catch them while they're young", as he put it. Infant schools would be invited to put together something the size of, for example, a film cannister, while secondary schools might want to try something on a larger scale*.

As for the budget rocket, Moreland said they hoped to go for a test launch is summer 2007. Reassuringly, he told us it would never be used in anger against Oxford University. ®

*While we were on the phone, Carl rather agreeably offered The Register some payload space on a future flight. Accordingly, we've decided to throw this one over to you, our beloved readers. More details here.
