Prerequisites: None
Levels: Newbie, Trainee, Dandy, Progidy.

In this challenge, your spuCraft is dropped into a deep hole. With the three thrusters, you are able to slow the vehicle down and even turn it around to head upward. The challenge is broken into two parts. The first part of the challenge is all about getting the feel for piloting the craft. Feel free to control it by hand. By default the thruster signal, is connected to the right thumbstick on the gamepad, vertical axis. Try to land safely. To progress to the next part of the challenge, though, you might need to make a stop on the way down. The second part of the challenge is where you are truely tested. To avoid touching deadly flowers, you are going to have to deploy a protective halo. But it’s harder than it looks. To match speeds properly requires super-human precision. This is an engineering problem that requires an understanding of Newton’s Second Law and position/velocity/acceleration kinematics, as well as some computational thinking.
