John Batchelor and I welcomed back Bill Harwood of CBS Space News to discuss the four spacewalks needed to repair the cosmic ray detector (Alpha Magnetic Spectrometer) on the ISS.  We discussed the science being done by this instrument, how it has lasted far longer than expected, what the repairs are for and what they mean for this type of science on the ISS and for the study of cosmic rays, dark energy, dark matter and more. Bill then discussed serious concerns about commercial crew given the last Soyuz ride for NASA astronauts is in early 2020, what it will mean if either the CST 100 or the Crew Dragon is not ready by then, what a reduced crew on the ISS will mean, and more.  Budget issues were talked about as well.  Don't miss this information packed one segment Hotel Mars program.
