Launch to Space.

Use what you learned about thrust, weight, fuel, and staging to deliver a satellite to space.

Remember: thrust must beat weight to climb. Empty stages are dead weight, so rockets drop them.

More thrust uses fuel faster.

Your mission: deliver the satellite

  1. 1Launch: move Engine Thrust high enough that thrust is greater than weight.
  2. 2Stage: when Stage 1 empties, quickly press DROP EMPTY STAGE. A lighter rocket climbs more easily.
  3. 3Space: once the debris challenge begins, fuel no longer matters. Use ← / → to survive 20 seconds of fast-moving debris.

Raise thrust until it is greater than weight.

You can also use the ← and → arrow keys. Keep using thrust while you dodge.
