So for the last few months the main item of procrastination within the department has been to form The University of East Anglia’s space program. This is a collaboration project of UEA PhD students and faculty members who have formed an organisation codenamed BLEAT, the Balloon Launch Exploration and Analysis Team, and also known as ARSE, Andrew Rushby’s Space Explorers (our website). Since Commander Rushby (see his blog to see just how much he really loves space) first proposed the idea of establishing Norfolk’s long overdue position in the race to commercialise spaceflight back in March we have been putting a lot of time into making this dream a reality. This is unlikely to aid anybody’s actual work, we’re just doing it for an excuse to do some exciting science in space, because we can and basically (to paraphrase Mallory before he attempted the first ascent of Everest) because it [space] is there.

The first mission, with launch scheduled for 10:00 hours GMT tomorrow (01/12/2012) is a preliminary mission to send cameras and a GPS tracking system attached to a weather balloon up 30km to the edge of space. As well as hopefully getting some cool photos this should allow us to test our methods of launch and recovery so future missions can have a more advanced payload – there’s talk of developing an ‘air-core’ unit to sample the air column at varying heights and also to maybe send some single-celled organisms up as Norfolk’s very first astronauts.

As Chief Engineer, it’s been my primarily my job to develop the launch vehicle and make it space worthy. This has mostly involved scrounging materials from the labs and building the ‘Spacebox’ the (hopefully) space-proof capsule that will contain and protect our payload from the hostile environment of near-space. At ≈33km up (the maximum our balloon can reach before exploding as it expands to 20 times its launch diameter) It will have to survive low pressures that would make your blood boil and tissues explode and temperatures down to -80oC, and then survive the ride back to Earth attached to a rather small parachute, so it’s been heavily insulated and securely duct-taped to perfection (although it has to still be able to vent excess pressure so is not completely air-tight).

The top-secret launch site – a field in Burton-on-Trent – has been carefully selected by our team of resident Meteorologists led by Tactical Officer Surl. Using computer simulations (developed at Cambridge University) to predict the balloon’s path as it is strongly influenced by the weather conditions and changes in the jet stream this is the closest location to Norwich we can launch from if we want any hope of our payload still landing in East Anglia. Just in case, attached to the capsule are multi-lingual instructions for its return in English, French and Dutch, kindly translated by members of our international team, although if it does not land before reaching the coast it is likely it will end up on the bottom of the North Sea.
Today the final preparations have been put in place, after we finally got CAA approval yesterday, first thing this morning we tested whether it would be possible to transport the balloon fully inflated – to get around regulations on transporting pressurised gasses – but unfortunately it was too big to fit it Captain Mill’s balloon transport vehicle (BLV aka camper van). Luckily however Admiral Professor von Glasgow is fully trained in pressurised cylinder transport and has kindly volunteered to separately drive the helium up for us while we follow in the BLV.
Once launched we will track the balloon’s progress using the GPS system and, orchestrated by Science Officer Chylik running ground control out of UEA and predicting the flight path, the chase team led by Captain Gooch will fearlessly race across East Anglia to recover the payload, or to hopelessly watch it crash (possibly in flames) into the sea.
None of this project would have been possible without the time and dedication by many more people than it has been possible to name above nor the money kindly donated by the UEA (with surprisingly little begging involved. A further mention needs to go to the journalist Michael Brown who has been following us for the last few weeks to put together press coverage for Concrete (UEA’s student newspaper) and has also been instrumental in securing extra funding from the Student Union.

An update on the outcome of the launch will be posted next week, although you can follow our Twitter feed for exciting live updates, but I thought I should write this pre-launch just in case it all goes wrong while we’re still relatively optimistic and nothing has yet crashed and burned. However, whatever we do, it's never going to be as cool as this by some students from Harvard:
