He runs a website The Physics of SpaceX (http://thephysicsofspacex.wordpress.com), dedicated to breaking down various SpaceX topics, specifically:

- Explaining the infeasibility of second stage re-use - Comparing first stage rocket engines - Comparing upper stage rocket engines

The cool thing is that he does so from a first principles standpoint.

In the interview we cover a bunch of different topic areas related to SpaceX and mars colonisation.

The interview can be listened to online: http://radio2.marssociety.org/2016/09/18/rpr-episode-3-thomas-myers-physics-of-spacex-blog/

Content includes:

- Intro to Tom and how he came to start his blog “The Physics of SpaceX” - Why SpaceX only reuses the first stage of the Falcon 9 - What SpaceX Mars colonisation logistics may look like (BFR + MCT). How the MCT could re-fuel in space - How “breaking” when arriving at Mars works - Fuel options on Mars (Methane or Hydrogen) - Who might be the first people to go to Mars? - Discussion of Skylon’s single stage to orbit liquid hydrogen concept - Ion engines and “going the long way around” to Mars - 38m – How ion engines work (vs liquid propellant) (loosely explained) - SpaceX plans for creating an internet satellite network - 51m – In situ-resource utilisation. Why we want to go to Mars vs building something in empty space. - Asteroid Mining - Feasibility of living underground on Mars - 1hr – Future Mars governance & future independence - Self driving cars on Mars - 1hr 18m – Virtual Reality utilisation on Mars - 1m 28m – Various rationales for going to Mars - 1hr 31m – Comparing the discovery of the Americas to Mars exploration
