It seems like everyone's pretty stressed out about VCE/Uni at the moment, and what we all really need is some video game therapy! I was talking to Cthulhu on IRC lately and that reminded me to get you guys into it!
Kerbal Space Program
What is KSP?Basically, Kerbal Space Program is a game where you can design and launch rockets.
You're given a plethora of parts, a capable crew of three (know as Kerbals), and a basic staging process that allows you to launch parts when they need to be
What are the objectives or goals in the game?There's no real defined goals, so it's great if you can make your own.
For instance my goals have been
- Getting a ship into space (DONE!

)
- Getting a ship to stay in a non-decaying Orbit (DONE!

)
- Getting a ship to the moon (not done, I came close but I missed the moon ): )
Where can I get it/is it free?The demo is free (and isn't too different than the paid version) and can be downloaded from the link below.

You should be able to show to your parents the calculations you use to find Planetary Phase Angles (the angle two planets should have to each other, maintaining the angle from one planet with the sun as a vertex)
Which can be given by,

Additionally, even some parts of VCE Physics comes into it (don't tell pi) namely, Keplers Third Law! Which we should know will allow you to calculate the mass of Kerblin without knowing much else.
Do I have to do the math?It's up to you, I'm personally not doing the Maths and taking a more trial and error approach (many Kerbalers were harmed)
