Exploring Mars

๐ŸงชLab Brief #14

Exploring Mars.

๐ŸŽฏ Your mission

Run the experiment. Find out what really happens.

โšก The twist

Gravity is invisible โ€” but it shapes everything.

๐Ÿคฏ

Mind = Blown

๐ŸŒŸ The light from the closest star (after the sun) takes 4 years to reach you.

๐Ÿ”ฎ

Before you check: which is closer?

What You'll Learn

Mars is called the Red Planet because iron oxide (rust) covers its surface. Scientists send rovers to Mars to search for evidence of past water and possible microbial life.
