To become Elite in Frontier: Elite 2

Buy a Mining laser. Buy a laser cooler. Go to Phobos or Deimos (the moons of
Mars, in the Sol system at [0,0]. You should see the moon as an asteroid-type
body. Point your mining laser at the rock, and keep firing. While doing that,
press SHIFT-F3 so time is 3x accelerated. Each time you hit the asteroid, it
counts as one kill. So, if you keep doing this you'll be Elite in a few minutes.
