We welcomed Dr. Andrew Rader to the show to discuss his aerospace engineering lectures and other material on his website, www.andrew-rader.com as well as his YouTube channel. You can access all his material, his YouTube channel and his book through his website. During our one segment one hour discussion, Andrew talked about his Mars cooking video regarding his eating bugs. We had quite the discussion about this. Crickets anyone? Next, we talked about going to Mars and he introduced us to his YouTube channel which has 74 videos and more on it. His aerospace engineering class lectures are there too and very popular with students, especially those wanting to see if aerospace engineering might be the path for their studies. Joe asked our first email question about the necessity for a flyby or human orbital mission of Mars prior to humans landing on Mars. We then discussed Mars, why a one way mission, and the Moon vs. Mars. Other topics included spacecraft and rockets in general, Apollo, robotic missions, and more about human spaceflight. At one point I asked Andrew how he stated the purpose for our going into space. Bethany asked Andrew to explain what was meant by the term ecliptic. In response, Andrew offered a short explanation using basic orbital mechanics. We talked about several specific videos on his YouTube channel including the Sagan Darkness video, the Ambien Space Music videos and the Star Trek and Darth Vader videos. I asked him what he liked best and he said it was systems engineering because he liked putting and seeing how everything works together. Human factors came up and he made an interesting statement to the effect that if we require 21st century medical care on our space missions, the technology itself may be an impediment to the mission. We talked about the multi-systems failure risk being the biggest risk in his opinion and the steps taken to mitigate this risk. I also asked about crew failure risks including medical and psychological issues. Andrew offered us interesting observations about crew risks and issues so don't miss what he said. As the show was drawing to a close, we talked about his introduction to spacecraft videos. Please post your comments/questions on TSS blog. You can reach Andrew through his website or me.
