Rocket Tailor turns rocket staging into a puzzle
The site describes an iPhone puzzle where players move rocket-stage boundaries and choose propellants to see how much cargo could reach orbit.
- For
- iPhone users curious about rocket launches
- Worth noticing
- The model ignores reuse and counts boosters as a stage; the page warns its numbers are not engineering data.
Field notes
The page describes a deterministic rocket-equation model calibrated so each vehicle’s real stage split reproduces its published cargo on a reference orbit; it explicitly says the results are directional, not engineering data. Its mission set spans five “floors” and includes Diamant, Black Arrow, Saturn V, Ariane, and the James Webb Space Telescope. A launch-day challenge is described as closing before countdown and comparing a player’s staging choice with the flown design.
