We welcomed back Robert Walker from the UK to discuss artificial gravity with us given our recent Space Show programs on the subject. There was an audio issue with this program so listen carefully so you don't miss anything. During the first segment of our 90 minute program, Robert went over some of the basics such as the Coriolis effect, the gravity gradient, tethers, centrifuges, the vestibular effect, and more. He also went over linear acceleration, spin rates, Russian experiments, issues facing space tourists, and spinning a Dragon capsule. Robert has written many articles on artificial gravity which can be found at One such article was discussed yesterday. See Also, check out; & In our second segment, Robert talked about both Inspiration Mars and Mars One as it relates to spinning to create artificial gravity, the number of revolutions per minute, simulate programs, and his favorite, a 2-3 year precursor mission at Earth L2. He wants the mission designed to be a comprehensive test bed for artificial gravity. Later in the segment while discussing Mars, he suggested we orbit Mars and not land on the planet. Listen to his reasoning for this type of human Mars mission. For one thing, he said its much safer to be in orbit. We then focused on the possibility of microbial life on Mars, we talked about the Viking Labeled Release experiments. Robert was asked a question about the sleeping centrifuge (you sleep horizontal as one does on Earth). Partial gravity was discussed as well. Robert said many times that we must find out what is going on with Mars. He mentioned the Phoenix mission which Mars One is planning to copy to some degree with its robotic mission to Mars in 2018.
