Spaceling — Moons, Gravity & Exploration Moon Crater Ridge

Hi!

I'm Spaceling.

Welcome to Moon Crater Ridge!

Will you help me investigate moons, gravity & exploration?

The Grumblies have mixed up our clues.

Let's check the evidence!

Moons are natural satellites of planets or other bodies.

Gravity affects their motion;

different worlds have different surface gravity.

What is a natural satellite?

  • A. Every telescope
  • B. Every artificial spacecraft
  • C. A moon

The answer is C: A moon

Moons are natural satellites of planets or other bodies.

Gravity affects their motion;

different worlds have different surface gravity.

That clue helps us make sense of this place.

Many craters form when objects strike a surface.

Images and measurements from probes help scientists investigate places people

cannot simply visit.

What commonly forms an impact crater?

  • A. Ordinary sunlight alone
  • B. A collision with a space object
  • C. A shadow crossing the ground

The answer is B: A collision with a space object

Many craters form when objects strike a surface.

Images and measurements from probes help scientists investigate places people

cannot simply visit.

Hmm...

how does that connect to our first clue?

Our question asks how wide a crater is.

A calibrated image with a scale helps answer that;

an unscaled picture can show shape but not establish the exact width.

Which record helps measure crater width?

  • A. An image with a known scale
  • B. An unscaled picture alone
  • C. A drawing with no measurements

The answer is A: An image with a known scale

Our question asks how wide a crater is.

A calibrated image with a scale helps answer that;

an unscaled picture can show shape but not establish the exact width.

Nice investigating!
