Activity Transition

• Previously, we considered getting to the moon.
  Now we will consider landing on the moon, and
  what we do once we get there.
• Build Lunar Rover Transport
• Build a Landing Pod for Rover
• Launch the Rover in the Landing Pod

Challenge 5

• Carry people and cargo while on the moon.
• Carry one plastic egg snugly. The egg may NOT be
  taped or glued into place.
• Have room for two plastic people. (The people do
  not land with the rover. They will get in the
  rover on the Moon and drive it around.)
• Roll on its own down a ramp for an average
  distance of 50 cm or more.
• Be strong enough to hold approximately 5 grams of
  cargo weight, represented by two Tootsie Roll or
  other candies inside the egg. Survive the
  landing. This means it should be able to roll
  down the ramp after the landing, and the plastic
  egg should not have popped open.

CEV Launch.

• Launch the CEV.
• Accuracy (hit the target on the floor).
• Control Adapt Launch to Improve Results.
• Be reusable. Doesnt Break
• Be Repeatable
• Three launches should have similar/identical
  results.
• Changes in force or direction should be
  predictable and controlable.
