Earth orbit for £1,000? You must be joking
Amateur boffins vie for 'very nearly' impossible N-Prize
We're obliged to all those readers who sent in suggestions as to just what El Reg's new Special Projects Bureau  should be doing with its multi-billion pound budget and mountain fab bunker complex, and the first thing that caught our eye was the N-Prize  – "a challenge to launch an impossibly small satellite into orbit on a ludicrously small budget, for a pitifully small cash prize".
The N-Prize was launched by Cambridge biologist Paul Dear in 2008. It's aimed at "amateurs, enthusiasts, would-be boffins and foolhardy optimists" who can demonstrate "creativity, originality and inventiveness in the face of severe odds and impossible financial restrictions".
Here's the explanatory blurb:
The N-Prize offers two cash prizes, each of £9,999.99.
The prizes will be awarded to the first persons or groups to put into orbit around the Earth a satellite with a mass of between 9.99 and 19.99 grams, and to prove that it has completed at least nine orbits.
One prize (the "single-spend-to-orbit", or "SSO" Prize) will be awarded to the first entrant to complete the challenge using a non-reusable launch system. The other prize (the "reusable vehicle" or "RV" Prize) will be awarded to the first entrant to complete the challenge using a partially or wholly reusable launch system. Both prizes carry equal status.
The cost of the launch, but not ground facilities, must fall within a budget of £999.99. Entrants for the RV Prize may exceed this budget, but must demonstrate recovery of hardware such that the per-launch cost remains within £999.99.
Imaginative use of string and chewing gum is encouraged. Entrants are responsible for everything, organisers are responsible for nothing.
The N-Prize website describes the challenge as "very nearly" impossible, and we're inclined to agree.
Nonetheless, several teams  have taken up the gauntlet. A quick shufti at the competitors' projects shows a predictable penchant for purely rocket-based systems, although this band  of Discworld fans provocatively mention a rockoon concept, while NZ's Team Anahera Tere  delightfully suggests a "very large cannon" might be a viable first-stage launch system.
Co-incidentally, our own Paper Aircraft Released Into Space (PARIS ) project got us thinking about rockoons (rockets launched from high-altitude balloons), although a quick calculation on the back of a beer mat shows that the cost of a balloon, and the helium needed to lift a rocket would eat up a good percentage of the N-Prize maximum budget.
So, it remains to be seen if anyone succeeds in claiming the N-Prize before the deadline of 19:19:09 GMT on 19 September 2012. We're sure some of you garden-shed boffins have a few ideas as to how the impossible can be achieved. ®
