RPR Episode 3 – Thomas Myers (Physics of SpaceX Blog)

Podcast host John King, interviews Tom Myers, physicist and blogger at The Physics of SpaceX.

We delve into Mars colonisation logistics and future potential technologies. See below for detailed breakdown of discussion.

Subjects discussed, in approximate chronological order:

  • 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 (Tom explains extrapolating from the rocket equation + other calculations the infeasibility of second stage re-use)
  • What SpaceX Mars colonisation logistics may look like (BFR + MCT). How the MCT could re-fuel in space.
  • How “breaking” when arrive at Mars works (high level) using aerobreaking + retropropulsion
  • Using SpaceX Mars logistics for other organisations (universities, governments) to put things on Mars.
  • Tom’s background in rocketry – competing in solid fuel rocket building competitions against the USA + French
  • 21m – The complexity (?) of an engineering leap from kerosene based fuels to methane
  • Fuel options on Mars (Methane or Hydrogen) + tradeoffs between the two
  • Who might be the first people to go to Mars? SpaceX Engineers / NASA astronauts
  • Mars collaboration going forward? ESA, JSA, China
  • Will others be able to copy/compete with SpaceX?
  • Discussion of Skylon’s single stage to orbit liquid hydrogen concept, how it could bring down the cost of transporting payloads into orbit (in the future), and how extra ‘players’ will increase redundance capacity (should something happen with a BFR etc)
  • Ion engines and “going the long way around” to Mars, to reach it outside of transfer windows
  • 38m – How ion engines work (vs liquid propellant) (loosely explained)
  • If ion engines can go 10x faster, how do they break at the other end? Force of air resistance scales with square of speed
  • 42m – Why ion engines won’t work within the Earth’s gravity
  • SpaceX plans for creating a satellite network to share internet across the world. How it will benefit the world + SpaceX. Including creating communication between Earth + Mars
  • 51m – In situ-resource utilisation. Why we want to go to Mars vs building something in empty space.
  • Resources available on Mars
  • Why asteroid mining from Mars is more appealing than from Earth
  • Feasibility of living underground on Mars – including the speculated empty lava tubes
  • 1hr – Future Mars governance & future independence
  • Self driving cars on Mars
  • 1hr 10m – How Mars will help drive new innovation – through necessity
  • 1hr 18m – Virtual Reality utilisation on Mars – helping the colony to handle reduced space and movement options.
  • 1hr 23m – Gravity on Mars
  • 1m 28m – Various rationales for going to Mars
  • 1hr 31m – Comparing the discovery of the Americas to Mars exploration

RPR Episode 1 – Dr. Robert Zubrin

doctor-robert-zubrinThis episode features and interview with Dr. Robert Zubrin, Founder and President of the Mars Society, an American aerospace engineer and author of The Case for Mars, best known for his advocacy of the manned exploration of Mars. Today’s host is Bill Hargenrader, bestselling author of Mars Journey, and Founder of the popular I Love Mars Media

Dr. Zubrin was the driving force behind Mars Direct, a proposal intended to produce significant reductions in the cost and complexity of such a mission. The key idea was to use the Martian atmosphere to produce oxygen, water, and rocket propellant for the surface stay and return journey. He is the President of the Mars Society and Pioneer Astronautics and Pioneer Energy. He has developed a number of concepts for space propulsion and exploration, and is the author of over 200 technical and non-technical papers and five books.
