We welcomed Wayne Eleazer to the show to discuss the history and why of rocket launch failures per the many articles he has written over the years on these subjects for The Space Review.  In the first segment of our 1 hour 58 minute discussion, Wayne started us off responding to my question about the most dramatic launch failure he has seen or studied.  He talked about a spectacular Titan failure so don’t miss his story.  Michael Listner called and talked about many topics including Air Force mishap reports.  What Wayne had to say about the mishap reports and the Air Force candor regarding launch failures was very interesting and informative.  Wayne introduced us to the Oops Factor regarding failures, a concept he used in an earlier Space Review article.  This refers to one thing causing the launch failure but the people down the line with oversight responsibility all miss it or “oops!”  SpaceX and the Falcon 9 problems came up many times but here Wayne talked about the needed culture in a company to deal with launch failures, learn from them, and work to keep them from happening again.  He thought SpaceX was doing all of that.  He also talked about Orbital ATK and the Antares and their culture, then I asked him about the SpaceShip2 failure/accident.  Near the end of the first segment, Jay asked Wayne if military rockets had similar launch failure problems.  Wayne’s response about the military rocket motor, its reliability, testing, and costs was most illuminating.  As we learned, the military rocket motor stands alone in quality.

In the second segment, Wayne was asked if he could spot trends that cause launch failures over and over again.  He said no but listen to his complete answer.  He called this the “Predictables” and is completing a new Space Review article on this subject.  He listed several examples including his use of the Challenger loss as well as Delta and Atlas failures.  I asked him if on the military side, there were consequences for military personnel with responsibility and oversight duties, maybe a demotion, court martial, anything.  You might be surprised by his answer to this question.  We talked more about the Falcon 9 and EELVs in this segment, plus the old Thor and the Atlas.  Barry asked Wayne about Russian launch failures.  Wayne talked about the Russian culture and problems.  Near the end, he said EELV reliability was improving.  He made some additional Atlas and Falcon 9 comparisons, then I asked if there was an expected failure rate for these rockets.  Wayne suggested if a company survives ten launches, their odds for survival improve greatly.  Doug asked about fairing issues. Wayne talked about the ways that a fairing can open up and we talked about the recent Taurus failures due to fairing problems.  Doug followed up his question asking about the reliability for the Falcon Heavy.  Wayne had much to say about reliability and strap on rockets &the odds of a failure by strapping rockets together.  You might be surprised by what he said.  I asked him about modular all purpose, all mission rockets, complexity vs. simplicity, small start-up launch operations and the SLS.  In concluding the show, he talked about the value in understanding launch failures.  He talked about education on launch failures and why it has been so hard for people to be open minded and learn from rocket failures.  At one point, he mentioned an older German rocket company building an ugly pipe rocket, OTRAG.

We welcomed Ben Haldeman of Planet Labs to the show.  During the first segment of our 87 minute show, Ben introduced us to Planet Labs, told us about the company history, goals, and Dove satellite imaging program wherein they want to image the entire Earth every day.  You can find out more about this at their website, www.planet.com.  Ben described the size and nature of their satellite fleet, how they can cover the entire planet once a day, their agnostic launch  policy, and their cubesat manufacturing process for their 10cm x10cm x by30cm finished product.  He explained the company’s iterative approach, the company employee growth, and their recent payload losses on the Antares and the Falcon 9.  We talked at length about the ISS process of getting the Dove satellites, launching them from the ISS, and the astronaut training needed to carry out the Planet Labs mission.  Also discussed was the orbital decay profile for their satellites at the end of their life, altitudes for their Dove satellites, and plans to use the preferred sun synchronous orbit given the ISS may have a limited remaining life expectancy.  Ground stations were described as was the satellite pointing process.  Listeners asked many email questions including the use of off the shelf GPS and  the range of optical spectrum/wavelengths for the cameras/sensors being able to detect images.  Listeners also wanted to know if Planet Labs had plans to make satellites via 3D printing and if any radiation hardening was being used with their onboard electronics.

 

In the shorter second segment, we talked about Planet Labs hiring and their internship program.  The company mostly hires engineers but about 25% of their hires are from different disciplines.  They also hire a person a day so if you are interested, be sure to check it out.  They are located in a truly exciting and creative part of San Francisco, known as SOMA (South of Market) and this is the area to be in if you like technology, want to be on the leading edge of the cutting edge, and be surrounded by peers that redefine the meaning of the word.  You can find out more about their hiring and intern program by checking their website.  Adrian asked another question about solar sails and CCD cameras.  I asked Ben the question Debra was asked by a Mom on the Friday show regarding her child studying engineering but preferring Apple Computer for example over a space company.  I asked Ben to respond to that Mom’s question.  Don’t miss what he had to say about it as our discussion involved Silicon Valley, being located in the San Francisco Bay Area which is a highly evolved tech market place, including the Bay Area universities, and more.  Ben ad some very interesting observations about this and was able to address what is happening in other parts of the country that are not as tech dominated as Northern California.  Before the show ended, Ben was asked about the future financial plans for the company, plans to work with Bigelow private space stations, and polar launches from Vandenberg.  Don’t miss his concluding comments as he told us what excited him about his work.  Remember, while he liked space, he did not come to Planet Labs from college as a space geek or advocate, thus his perspectives were most interesting and we thanked him for sharing this information with us.
