John Batchelor and I welcomed Dr. Jeff Foust for the first ten minutes of our special edition Hotel Mars program. Our second guest was Doug Messier for the second half of the program. During the first segment with Dr. Foust, we talked about the latest news on the recent Orbital Sciences Antares rocket failure. It seems that Orbital Sciences is going to phase out the AJ26 rocket motor, replace it with a yet unidentified motor, and possibly do some short term launches of cargo to the ISS on an alternative rocket. In the second segment, Doug Messier of www.parabolicarc.com was our guest to discuss the latest news regarding the SpaceShipTwo accident. Doug talked about the NTSB investigation and disclosure about the on-off switch for the vehicles feather system, we talked about Virgin Galactic safety and the type of data that was collected which will assist the NTSB in the investigation. Please post any comments/questions you might have on The Space Show blog. You can contact any of us through me.
