As many of the Events listed below will be flown at IRW as entries for them are presented.

Scale Contest.

Scale Contest. Theme: Centenary Mars

On 23rd August 1924 - that is, exactly 100 years before IRW 2024 Friday - Mars made its closest approach to Earth since the 10th century. To mark this event, the theme for the 2024 IRW scale contest is "Centenary Mars". Any Mars-themed rocket is allowed. A safe flight is still required, so although a "War of the Worlds" Martian cylinder would be permitted, a realistic landing would not! - under the "no penetrators rule". (Bonus points will be scored if it deploys a tripod as in the book by H.G Wells, or a flying machine as in the 1953 George Pal film of the same title.) Fictitious (SF) vehicles either coming from Mars or going there are permitted. Real vehicles going to Mars are also permitted. Real vehicles coming from Mars are permitted if you can provide evidence of their origin.
