Embedded below the fold in two parts. The second part starts off with my somewhat scathing look at the disaster that is SLS.

Embedded below the fold. The first segment is entirely devoted to my analysis of the GAO report that described the continuing and never-ending delays and cost overruns for most of NASA’s big projects, such as SLS, Orion, Webb, and WFIRST, to name just a few.

Embedded below in two parts. This podcast actually features science writer Joe Pappalardo talking about Orbital ATK’s effort to make solid rockets competitive in the commercial rocket industry. John Batchelor asked me to join him in asking some questions.

Embedded below the fold in two parts. The first part of this podcast is definitely worth listening to. I go after NASA for both SLS and Webb, which seem to be projects in a competition to see who can last the longest without accomplishing anything. Both are now creeping towards project length’s exceeding two decades, and neither is close to flying.

My two hour appearance with David Livingston on the Space Show last night is now available and can be downloaded as a podcast here.
This show was particularly interesting because of the high quality of questions from the callers. In fact, in many ways I think it might have been one of my most interesting Space Show appearances in a long time. Definitely worth a listen.
Embedded below the fold in two parts. The first segment I think provides a nice overview of the developing competition that I expect to see between big and small rockets in the coming decade.

Embedded below the fold. As I am in Israel and cannot do my regular podcasts with John Batchelor, he has dug up an appearance from April 11, 2013 and posted this today. He calls it “Classic Bob Zimmerman.” The topics included a description of the cracks that occurred in one of the early Orion test capsules, and where I expressed then my doubts of SLS/Orion. In the five years since the only thing that has changed is that they have had to delay its upcoming missions by several years.

Embedded below the fold. The second part is not yet up. This segment was a discussion of the Falcon Heavy launch yesterday. The second part, which I shall add when John makes it live, was a discussion of the big space projects of NASA and Russian, and a comparison of both with Falcon Heavy. The comparison is as always enlightening.
UPDATE: Second part now added!

Embedded below the fold. This podcast was taped just after the Ariane 5 launch yesterday but slightly before we had heard that the satellites had made orbit, so it is a little inaccurate, though the main point that Arianespace had had its first launch anomaly after 83 successfully launches remains true.
