Christmas Crackers Sheila Derges - "A visit to CERN" Sue Dipple - "The Thirty Metre Telescope" Dr Steve Barrett - "The Science of Santa"

Rocket science is thought to be hard because the maths of orbital mechanics gets in the way. This talk skips over the maths and looks at orbits, how spacecraft travel between planets and how they can park at Lagrange points.
