Classes 6–12 · about 7 minutes · free, no sign-up
What you will learn
Explain that lift-off needs thrust greater than weight, that orbit means moving fast enough sideways to keep falling around the Earth, and why rockets use stages.
How to play
- Choose the payload, the fuel and the number of engines.
- Check the thrust-to-weight number, then launch and watch the flight.
- Try one stage with lots of fuel, then try two stages.
- Finish three challenges, ending with putting a satellite in orbit with as little fuel as you can.
