Rules in brief
TThe N-Prize offers two cash Prizes, each of £9,999.99 (nine thousand, nine hundred and ninety-nine pounds and ninety-nine pence, sterling).
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 9 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.
