Ashwing Vasavada from NASA, Jet Propulsion Laboratory in California and a CALTECH / UCLA star, has been involved with the Mars Rover Curiosity for over eight years now and has virtually spent that time living on Mars through the Curiosity mission. If anyone knows the conditions on Mars, then it is Ashwin and in this episode he discusses in detail, the history of NASA's space missions as well as how they were conceptualized, designed and deployed. He also gives a first hand account on the various missions like Viking, Voyager, Hope & Spirit, Perseverance and talks about NASA's Mars 2020 missions and what could be expected moving forward.
