Mini Space Plan

Take on contracts, drag engines, fuel tanks, fairings and payloads onto the bench, watch mass, thrust-to-weight and reliability live, and stage by hand at launch.

Start from this prompt

Run a pocket space center: take contracts to earn budget, research and assemble engines, fuel tanks, fairings and payloads, then pick a window to launch satellites. After ignition, handle stage separation and payload release by hand, and keep improving the rocket based on orbital deviation.

Run the Lunar Resupply

Change the missions into a lunar resupply program: complete a low-Earth test, a lunar transfer and a landing resupply in sequence on a shared budget and inventory, with each result shaping the next launch.

Build a web management game called "Mini Space Plan": the player runs a pocket space center, earning budget from contracts to research parts, assemble rockets, schedule launch windows and put satellites into their target orbits; failed launches cost parts, but research progress carries over for the next iteration. On the assembly screen, drag engines, fuel tanks, fairings and payloads into place while mass, thrust-to-weight ratio and reliability update live; during launch, use clicks or the spacebar for ignition, stage separation and payload release, with constant feedback on budget, fuel, altitude, velocity, orbital deviation and mission rating, plus pause and redesign options.The art uses cardboard-model low-poly rockets, deep-blue star charts and bright mission badges, with a trajectory line and mission-control cheers when orbit is reached; on phone portrait screens, the assembly area becomes step-by-step cards, the launch button stays pinned to the bottom, and precise dragging is never the only way to play.
Make It a Science Handbook

Restyle it as a bright children's science handbook with crayon planets, cutaway rockets and sticker badges for the numbers, plus fold-out mini-experiments on thrust, orbits and staging.

Add Emergency Control

Add emergency-control challenges: after liftoff, engine overheating, communication blackouts or attitude drift can strike, and players sequence a limited set of commands to stabilize the flight before failures cascade.
