Rockets and Astronauts

Rockets, astronauts, the Moon landing, satellites and telescopes

Getting to space is not primarily about going up. It is about going sideways fast enough to keep missing the Earth, and almost all of a rocket's fuel is spent on that.

The unit covers how rockets work, what astronauts actually do and what living in orbit involves, satellites and their uses, telescopes, and the Moon landings.

This unit breaks down into 21 short steps and 120 questions, starting at difficulty 1 and building to 2. Below you can see exactly what it covers, how the path is structured, and worked examples with explanations.

What this unit covers

  • Satellites
  • The Moon Landing
  • Telescopes
  • How Rockets Fly
  • Astronauts in Space

Where this fits

Accessible early. Space Missions covers the same programmes in more historical detail.

Where people slip

Orbit is not the absence of gravity. It is continuous free fall, which is why things float inside a station that is very much being pulled towards Earth.

How the unit is structured

Rockets and Astronauts runs as 21 short steps that unlock in order. 15 are practice rounds and 6 are challenge rounds that pull together everything before them. Questions start at difficulty 1 and climb to 2 as you progress.

  • Fact or fibLevel 2

    11. A rocket carries its own fuel and air to burn, even in space.

    Answer: True

    There is no air in space, so a rocket must carry its own oxygen to burn its fuel.

  • Odd one outLevel 2

    12. Which of these is NOT needed to launch a rocket?

    • A swimming poolcorrect
    • Fuel
    • A launch pad

Where these questions come from. Each unit starts as a plan of the concepts it should cover and the difficulty it should span. Questions are written against that plan with AI assistance, then checked by a validator that rejects anything without a single defensible answer, an explanation, or plausible wrong options. How we write questions sets out the whole process, and corrections are fixed in the bank and reach the site and the app the same day.
