Rules in brief

The N-Prize is a cash prize of £9, 999.99 (nine thousand, nine hundred and ninety-nine pounds and ninety-nine pence, sterling), which will be awarded to the first person or group 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. The cost of the launch (but not ground facilities) must fall within a budget of £999.99. Imaginative use of string and chewing gum is encouraged. Entrants are responsible for everything, organisers are responsible for nothing.
