Build it
Snap capsules, tanks, decouplers and engines together in a side-view builder. Every part has mass, fuel and thrust, and the numbers tell you whether it will make orbit.
A 2D space sim for Android
Build rockets from scrap. Fly real orbits.
Stack capsules, tanks and engines, light it up, and find out whether it holds together. Then reach orbit, put satellites to work, dock a station and land on the Moon.

Snap capsules, tanks, decouplers and engines together in a side-view builder. Every part has mass, fuel and thrust, and the numbers tell you whether it will make orbit.
Real orbital mechanics: gravity, apoapsis, periapsis and transfer windows, with time warp for the long coasts between burns.
Satellites and stations have jobs. Relays extend how far you can fly, and docked tanks become fuel depots in orbit.
Parachutes, heat shields and landing legs for the Moon and Mars, if you brought enough fuel to get back.
Every part is game art from the builder, drawn side-on so it stacks.

Landing legDuct Tape Rockets is in early development at Space Junk Industries. The orbital maths runs, the first parts are drawn, and the flight prototype comes next. A Google Play listing and test builds will follow.
