We welcomed back Michael Listner to discuss recent issues arising with the competition of SpaceX and Blue Origin (Jeff Bezos and Elon Musk) regarding reusability, barge landings in the water, patents, RD180 engine development and more. As you will hear, Blue Origin was awarded a patent on a barge landing in water which SpaceX is protesting.  Also, Blue Origin entered into an agreement with ULA, Boeing & Lockheed for a replacement engine for the RD180 based upon the Blue BE4 engine that has been in development for a few years.  Michael discusses these issues with us on this edition of Hotel Mars.

Please post any comments/questions you might have on The Space Show blog. You can contact any of  us through me.

1. Kirk - September 27, 2014

In both this show and the 26 September Space Show (with guest Rod Pyle) the subject of the BE-4 engine replacement announcement for the RD-180 was raised, and in both cases David Livingston noted that it was strange considering the significantly lower projected thrust of the BE-4: 550,000 lbf vs. about 930,000 lbf (vac.) for the RD-180.

According to the 17 September SpaceNews coverage of the announcement: “Two BE-4 engines generating a combined 1.1 million pounds of thrust at sea level would power the new rocket’s first stage, Bruno said. The current Atlas 5 first stage is powered by a single RD-180 generating close to 1 million pounds of thrust.”
