After a long absence, we welcomed Dr. Jeff Bell back to the show for a nearly 2.5 hour critique of NewSpace as well as traditional aerospace. In the first segment of our very long program, Dr. Bell started off talking about the SpaceShip2 accident and the NTSB report, then he went into a lengthy discussion about hybrid rocket motors. Later in the segment, he turned his attention to first stage recovery efforts regarding the Falcon 9, testing procedures, ground testing, and more. Jeff had much to say about these & other topics which covered the first hour of the program.

 

In the second longer segment, Jeff from Tucson was the first caller. He started off by talking about a book Dr. Bell had recommended on a previous Space Show program “Ignition.” Per our discussion, it is a free download book at http://web.gccaz.edu/~wkehowsk/ignition.pdf. Other topics in this segment included the Ranger Program, lots on cubesats as Dr. Bell questioned the usefulness of very small satellites. Later on, Dr. Bell recommended another book, this one by George Sutton, “History of Liquid Propellant Rocket Engines.” Another topic Jeff seemed to go after was what he referred to as, “NewSpace Patent Wars. He particularly zeroed in on the Blue Origin-Space X patent dispute over landing first stage rockets on a barge to achieve reusable first stages. Jeff then told how patent wars had been used over the years and he cited many different examples, including going back to Robert Goddard. Later in the segment, he suggested many of these influences were a result of the influence Silicon Valley has had on the space industry, particularly NewSpace. He then talked about booster recovery in general. Doug sent in a note asking Jeff which he preferred, the SpaceX’s propulsive recovery or ULA’s airborne recovery of just the engines. Before the segment ended, Jeff addressed Antares and the use of Russian rocket motors. More was said about cubesats, then Jeff took off on government subsidized programs. His last topic or target one might say was suborbital tourism. Don’t miss what he had to say about this part of the industry.

Welcome to our Open Lines show.  During our first segment of this 2 hour 20 minute program, we mostly talked about both the recent Antares rocket explosion a few seconds after launch and the Virgin Galactic SS2 accident resulting in the loss of one crew member.  After my opening statement about not engaging in accident speculation and my reading an op-ed by Dennis Wing on the accident titled “Thoughts on the SS2 Crash” (http://denniswingo.wordpress.com), we opened the lines for callers. Dr. Jurist called first to strongly urge against speculation.  Michael Listner called & updated us regarding the Air Force-SpaceX litigation, then Michael talked about the SS2 accident & to guard against speculation.  He did give us the relevant parts of the commercial space law pertaining to the Dept. of Transportation and FAA having regulatory oversight of the suborbital industry.  He cited 51 U.S.C. § 50903(c) & pointed out this paragraph:  “(c) SAFETY.-In carrying out the responsibilities under subsection (b), the Secretary shall encourage, facilitate, and promote the continuous improvement of the safety of launch vehicles designed to carry humans, and the Secretary may, consistent with this chapter, promulgate regulations to carry out this subsection.”  Dr. Rowe called and talked about cardiovascular risks for longer spaceflights as well as the problems associated with using pharmaceuticals in space.  Bill also addressed some space tourism issues.  During this segment, I read an anti-space tourism article from Wired.com which you will see on the Dennis Wingo Blog as Dennis commented on the Wired article.

In the second segment, Kirk called from Trinidad.  He mentioned the SR71 flight breakup with Bill Weaver and the loss of the other pilot, plus I asked questions about the interest in space in Trinidad.  Dr. Dwayne Day called next to resist speculation on the SS2 accident, plus he shared some of his experiences in accident investigation and how things progress as he was part of the Columbia investigation team.  We then talked about really bad network and cable news reporting on both the Antares rocket failure and the SS2 coverage.   Dwayne recently did a tour of SpaceX and ULA so he told us about each one and highlighted some of the differences that he saw regarding each company.  I think you will find this discussion very interesting.  Dwayne mentioned early commercial spaceflight history, problems, and setbacks as points of reference for us.  Tim called from Huntsville about the SS2 crash and the Russian engine used by Antares.  He wondered if the British Skylon space tourism vehicle would be an alternative.  SLS John was our final caller who again urged against speculation on the cause of the accident.  He mentioned risks to the space tourism industry and concluded saying what others have said and that is that rockets are a risky business no matter what.
