We welcomed Robert Walker back to the program for a stimulating 2 hour 15 minute discussion on lots of topics. We started out with an active back and forth verbal exchange on commercial spaceflight participant FAA rules as Robert believes that there should be regulations to control or prevent what was later deemed to be reckless rather than risky launch activity. Don't miss this nearly 30 minute back and forth with Robert and myself. This discussion came about because we were featuring Robert's recent article on not wanting to fly to the Moon on a Dragon if one paid him a billion dollars. The article is referenced in the newsletters plus you can find it on Robert's science20.cm website. We also talked other topics with lots of callers and those sending in emails. For a full summary of this program, make sure you read the review posted at www.thespaceshow.com for this date, Monday, April 24, 2017. Please note that Robert has posted important links relevant to our discussion on the blog so don't miss them.
