Space Exploration & Technology
📋 What it is
Rockets, probes, rovers and crewed missions let us reach places too far or harsh for people to visit easily.
🗣️ Coach says
We explore space with purpose-built machines. Rockets escape Earth’s gravity, robotic probes fly past distant planets, rovers drive across Mars, and crewed missions push human reach. Each tool is matched to a place too far, too hot, or too airless for us to just go.
🧠 Memory hook
Rockets launch · probes fly-by · rovers drive · crews push the frontier.

Why was Venus so hot-headed?
Because it has a runaway greenhouse effect!
😲 Whoa!
It takes radio signals from a Mars rover 5–20 minutes to reach Earth — so drivers can’t "steer" live; the rover must think for itself.
✅ Quick check: Why can’t engineers drive a Mars rover live with a joystick?
Say your answer out loud first — then reveal.
Radio signals take minutes each way, so the rover must follow pre-planned commands and handle hazards on its own.
Light-speed delay makes real-time control impossible.
🧪 Try it! (2 minutes)
Design a "rover" for a place you can’t go (deep sea? volcano?). What sensors would it need?
