Transcript

if you want to fly to Europe you contact a travel agent and they help you work out the logistics of how to get there or you do it yourself but it's really hard anyway if you want to fly to somewhere in the solar system then you contact the NASA equivalent and interplanetary travel agent and my guest today is one of these he's Dr Damon Landau he wor...
