A little over a year ago (April 2016) I wrote my second post about building a spaceship to go to the Moon. I wanted to get back to this particular thread, in part, because I needed to re-create the graphic in OmniGraffle. The reason for that is my migration from Windows 10 to a Macbook Pro running macOS 10.12. I’d created the earlier drawings in Visio, but for whatever reason Microsoft doesn’t release a version of Visio for the Mac. Furthermore, my version of Visio for Windows, release 2013, won’t work with Office 2016, and Microsoft has decided it won’t upgrade my 2013 version to work with 2016 office. I paid full price for Visio 2013. OmniGraffle for the Mac is much less expensive, and just as powerful for what I need. And it looks a lot better. From this point forward this is the graphic I’ll use, when I need to use it.


The biggest problem with amateurs such as myself talking about personal space ships is forgetting budgeting and logistics. Budgeting means finding the means to pay for everything, from raw materials (which are expensive) to manufacturing to running it and ongoing refurbishment and repairs when needed. The closest examples to this is civilian aviation, in which a small aircraft capable of being licensed is expensive to purchase up front, and then has a constant cost due to operations and maintenance. And that maintenance is important due to being able to maintain air worthiness. Your aircraft must be airworthy in order to be authorized by the FAA to operate an aircraft in flight. You pay for that, and more significantly, you make sure you have the necessary budgeted monies to pay for that. Budgeting is more than just collecting a big pot of money and then spending it. Money has to be managed and fed, in proper amounts at the proper time, to multiple cost centers in order to get work done. Budgeting means you make sure you estimate (and then get) enough money to start with, then tightly control how it’s used over time. Because without a well-funded and well-run budget, nothing gets built nor launched if it is built. Part of the budget feeds a critical capability called logistics.


Logistics, with regards to spaceflight, is the detailed coordination of a complex operation involving many people, facilities, and supplies. Multiple companies involved in spaceflight (Boeing, Lockheed, SpaceX, Orbital Sciences, etc) have a large logistics component of their companies of almost mind-numbing complexity. They have to coordinate everything from gathering materials to building rockets to testing them, then matching them with paying costumers, to transport and setup through final launch. And with SpaceX, the landing and refurbishment of Falcon rockets (and subsequent re-use back into the launch process) is an added wrinkle to the whole logistical process. While doing all this everyone has rules and regulations that must be followed for proper safety and quality assurance, which adds more to the overall cost. And before the critics in the peanut gallery pipe up, you need those rules and regulations because of the harsh, unforgiving nature of space itself, let alone the act of launching a rocket with a payload.

And then there’s the logistics of the payload (satellite et. el.) manufacturers, who provide the primary reason for launching lots of rockets in the first place. They have their logistics systems, which must mesh with the rocket makers. And the rocket makers must mesh with NASA and the Air Force, who control the launch facilities through yet another complex logistics system which has been built up and tuned over decades of hard won knowledge and experience. Rockets just don’t go up on a whim. Launches are deeply planned events to minimize risk and maximize success. Poor planning often results in loss of expensive hardware, and sometimes, human lives. Rocketry boils down to the controlling of incredible energies to move material and humans off the surface of the Earth and into orbit. Science and engineering play vital roles in rocketry, but logistics and budgets are equally important. It might even be said that logistics plays the most important role of all.

the challenger accident

January 29, 2017


Shuttle Challenger, flying mission STS-51-L, with seven astronauts on board, exploded 73 seconds after liftoff on 28 January 1986. On board were

  • Francis R. Scobee, Commander
  • Michael J. Smith, Pilot
  • Ronald McNair, Mission Specialist
  • Ellison Onizuka, Mission Specialist
  • Judith Resnik, Mission Specialist
  • Gregory Jarvis, Payload Specialist
  • Christa McAuliffe, Payload Specialist, Educator

I was working directly for Martin Marietta (the future Lockheed Martin) at the east Orlando facility near Research Park and the University of Central Florida. MM had, and still has, a nice cafeteria facility with a large outdoor patio that allowed for great viewing of rockets lifting from Canaveral. I was watching because my wife was an English professor at Valencia College, and we were expecting our first child, a girl, in May. The launch had special meaning for me. I was there to cheer on, quietly in spirit, the women who were on that mission as well as the educator.

It was right before lunch, the day was cool, crisp, and clear out to the coast, and there were about two dozen of us standing and waiting on the patio. As Columbia’s launch plume cleared the tops of the trees we all started to talk excitedly. When the big bloom of smoke and the devil’s horns appeared about a minute after liftoff, the whole patio went silent. We knew. The patio cleared pretty quickly. Inside the facility all the TVs were tuned into the local news stations, and we all walked by constantly trying to hear the news. I went home that night numb.

Over the ensuing months we would learn what happened. It would come out formally in the Rogers Report. Nearly three years would pass before another shuttle launch. By then a lot had changed, and not for the better. One of the primary requirements drivers for the Shuttle, the Air Force, walked away from the Shuttle when they decided it too unreliable for their use and switched back to “dumb” rockets to loft their payloads. Belief in NASA’s invincibility was shaken, and drove an already slow internal bureaucracy to go even slower. This led to Shuttles continuing to fly, but failure after failure to find a substitute for the Shuttle. When all the Shuttles were retired in 2011 and mothballed to museums, the only way into space and specifically to the ISS was by buying expensive seats from the Russians on Soyuz.

Challenger has a special place in my heart and soul, for who and what we lost.
