The Awesome and the Tedious

Commentary by Mike Mackowski

There are some cool things going on in space exploration, and these are developments that involve true exploration. There are also a lot of things going on behind the scenes regarding how the National Space Society operates, and these can get rather tedious.

First, the awesome stuff. We are getting our first close look at two very interesting solar system bodies, Pluto and Ceres (not to mention Pluto’s several moons). Ceres, with its mysterious bright spots, get more and more intriguing as the images continue to get better. As the New Horizons spacecraft approaches Pluto, we are finally starting to see the dim planet’s personality take shape. The next couple of months will be fun and exciting.

There have also been some interesting developments in experimental space technology. The privately funded LightSail, a cubesat sponsored by the Planetary Society, successfully deployed a solar sail in low Earth orbit in early June. This technology has the potential for low cost, deep space missions with this new capability to move around the solar system. There are constraints, certainly (you don’t get anywhere fast, and it doesn’t work well in the darker deep reaches of space), but it is great progress. It is also refreshing to see success by a non-government sponsor of such technology.

Another technology demonstrator, NASA’s Low-Density Supersonic Decelerator (LDSD), did not fare so well. This inflatable heat shield and high speed aerobrake was tested again near Hawai’i, but the supersonic parachute disintegrated shortly after deployment. They had similar issues on a previous flight, and despite what might be considered a failure, this is how you learn. By observing a failure, you understand the limits of the design, and can now go back and fix it.

These demos are great examples of how we are advancing the technology that will expand humanity into the solar system. But on the policy level, I don’t think we are making as much progress. I think most people can agree on the goal of expanding mankind into space, but not on the path to get there. You have factions supporting SLS or commercial space, NewSpace versus traditional aerospace firms, etc. This week I was observing an email debate between lunar railguns versus lunar space elevators. In my view, that is a moot argument (especially for a forum on chapter issues), since neither one is going to happen any time soon. There was also a debate on how NSS should deal with the partisan bickering in Congress over NASA’s budget. I doubt that NSS has any influence over the eventual outcome, but we sure wasted a lot of energy arguing about it on teleconferences and emails.

From my perspective as the local leader of the Phoenix Chapter of NSS, I am looking for ideas and resources from my NSS national leadership on how to sponsor effective local events, how to recruit more members, etc. While lunar elevators versus railgun launchers may be an interesting academic discussion, that is not helping me figure our how to convert some new young space enthusiasts into future leaders of NSS at the local or national level. I fear that if these young candidate leaders are exposed to the constant internal bickering, pointless debates, and ineffective meeting management that is so typical of NSS, they will want nothing to do with the group on any level. As an organization, NSS needs to grow up and become more professional in how they set policy, support local chapters, and establish their public image. The Society’s tedious tendencies in these areas may be the very reason there are so few younger people willing or interested in becoming more active and involved.

General Atomics Blitzer Railgun

In 2007, building upon knowledge gained under an Office of Naval Research (ONR) Innovative Naval Prototype contract, GA initiated development of the Blitzer™ system using internal funds to accomplish two major objectives:

  • Demonstrate the technical maturity of tactically relevant railgun technologies in a proving-ground environment.
  • Generate interest in the viability of smaller Electromagnetic (EM) gun systems for use in a broader set of missions, including integrated air and missile defense (IAMD)

GA accomplished both of these objectives by demonstrating the launcher and power system technologies to full design levels in 2009 during testing with non-aerodynamic rounds, followed by testing of aerodynamic rounds during the fall of 2010.

The tests demonstrated the integration and capabilities of a tactically relevant EM Railgun launcher, pulsed power system, and projectile. The projectiles were launched by Blitzer at Mach 5 with acceleration levels exceeding 60,000 gee, and exhibited repeatable sabot separation and stable flight.

Changes at NSS

by Mike Mackowski

mjm

Over the past few days there have been some leadership changes in the National Space Society.  The executive director, Paul Damphousse, has resigned. He has only been in this position for about a year, and gave no specific reason for leaving.  On a more local note, our own Veronica Ann Zabala-Aliberto has resigned from her position as an at-large director as of this past weekend.

From my perspective, and while NSS does important things on a national scale, it is at the grass roots level that we can be most effective in promoting a strong American space program.  So no matter who serves in leadership roles, we really need active members at the chapter level to actually make things happen.  So thank you to the folks who came to last Saturday’s meeting, and we hope to see you and many others involved in future local activities.

I’d love to see your comments here with your thoughts on these changes and any other topics you’d care to discuss.

Your Very Own Personal Space Program

Michael Mackowski, a member of the Phoenix chapter of the National Space Society, has given us another interesting essay:

Your Very Own Personal Space Program

There are many ways folks express their interest in the space program. Some space enthusiasts read everything they can find and often have a large book collection. Some people accumulate souvenirs and autographs. Photos, patches, and pins are popular collectibles. Scale models can be another way to bring the space program to life in your home or office.

I have been inspired by space exploration since I was a youngster. Prior to finishing school and entering a career in aerospace engineering, my participation in the space program was limited to building scale models of the vehicles that were leaving the planet. Actually, I have never stopped building models of spacecraft, even while I build them for a living as an engineer. Like engineering, I find that modeling is just another expression of one’s creativity.

Over the years I have been participating in a network of other hobbyists with similar interests. What I have found is that many of these people, while being hobbyists and craftsmen in terms of their model building, are also passionate about space. My situation is a bit unique in that space is both my hobby and career. Most people who are passionate about space have other, usually non-technical careers. So one way they can feel closer to space exploration is by building small replicas of the hardware that makes it possible.

Certainly this sort of passion is the root of many hobbies. Military history buffs build models of tanks and fighter jets. Auto racing enthusiasts build race car models. Would be sailors rig up miniature ships and sailboats. People collect or paint miniature horses because they cannot afford to own a real horse. Airplane fans who cannot afford lessons or a plane can have a shelf full of models. Frustrated astronaut candidates build Apollo lunar modules and space shuttles. It’s not the same, but for many people it may be as close as you will get. It’s your own personal space program.

Enthusiasts want a piece of the space program they can see up close, hold in their hand, and relate to three dimensionally. Books and videos and internet sites are flat and virtual. A model is real and fills space. And you built it yourself. That’s why model building is more fulfilling than just collecting or buying pre-built souvenir models. You are now a rocket scientist, only scaled down, and with simpler technology. You have combined art with technology. You feel more a part of the movement, a part of the collective that is moving out to space. Through model building, you are more than an observer. You have made a statement, that by building this miniature monument to space exploration, you are supporting it, and proclaiming it to whomever enters your hobby room or office or wherever you chose to display your work.

If you can’t be an astronaut or be an engineer in the space industry, you can have your own little private miniature space program, and thus pay homage to whatever past or future off-planet venture that inspires you.

In that way, maybe it will inspire someone else, and the movement grows by one more.

Arizona State Space Exploration Symposium – A Review

Michael Mackowski, a member of the Phoenix chapter of the National Space Society, attended the one day symposium titled “The Future of Humans in Space” on 26 October 2012. He sent us these observations:

Notes from ASU Space Exploration Symposium, 10/26/12

I attended a symposium at ASU on Friday, Oct. 26, 2012. The name of the event was “Future of Humans in Space: Re-Kindling the Dream. The day-long symposium was sponsored by ASU’s Beyond Center, the School of Earth and Space Exploration, and the Center for Science and the Imagination. Here are my random notes on each speaker.

Hugh Downs (former television news personality and current chairman of the board of governors of the NSS)
He reminisced about NASA’s “glory days” when a leader like von Braun could make design decisions on the spot. Downs claimed that Werner saw the original Saturn V design with four engines, and suggested they add a fifth. There were no trade studies, no review committees, no cost-benefits trades, just a brilliant engineer with the freedom to get things done. Downs also talked about the early days of the National Space Society including how George Whitesides helped get it going.

George Whitesides (CEO and president of Virgin Galactic)
He talked about how Virgin wants to put more people into space. While he acknowledged these are suborbital flights, he avoided noting (until asked) that it is only for two minutes. He tried to make a case that these are exciting times for space development right now, with SpaceX proving their new capabilities and Virgin close to proving out the market for tourist flights into space. Just how this fits in with the theme of the symposium (“Why are we stuck in low Earth orbit?”), when Virgin doesn’t even GET to orbit was a bit puzzling to me. I’m all for rich people wanting to take their joy rides, and maybe this advances cheaper access to space, but I don’t see how suborbital tourist rides gets us closer to settlements off the Earth. Perhaps it can establish a space tourist market that can evolve into a LEO business, thus driving down launch costs. Whitesides did mention that Virgin Galactic has plans for orbital vehicles but that is a long way off.

Ed Finn (Director, Center for Science and the Imagination)
This center (http://csi.asu.edu) was one of the co-sponsors of this event and they had a few minutes to introduce themselves. A simple statement of their charter is to connect science and the arts. One of their efforts is to bring together scientists and engineers with science fiction writers. It’s another example of ASU president Michael Crow’s adventures in collaborations across disciplines.

Kip Hodges (Director, ASU School of Earth and Space Exploration)
He talked about collaboration between humans and robots in future space exploration from the perspective of a field geologist. His main point was that robots are unlikely to ever be as good as humans for exploration. Human cognition will always be superior to autonomous machines, but there is plenty of room for working together. The problem is latency, or the time it takes to communicate with a teleprescence on another world. Until we figure that out, robotic exploration will be slow and inefficient.

Panel Discussion: How to Leverage Our Investment in Space
This panel included Kip Hodges, Lawrence Krauss (physics professor), astronaut Andrew Thomas, and Paul Davies. I don’t think the discussion ever talked about leveraging our past investments, but the topic veered into how will we ever manage to get a manned Mars mission. All of the classic debate topics came up:
– Destinations versus Capabilities
– Moon versus Mars
– Robots versus People
– Science versus Adventure
– Settlement versus Political Prestige
– Government versus Entrepreneur
There was a consensus that the ultimate goal is human settlement on other worlds. But the path to get there is not at all clear. Astronaut Andy Thomas had a lucid view of the situation, in that space exploration is not a national imperative. Our indecisiveness is a social issue, not technical, not even political. It is still too expensive for private entities to bankroll, and the American taxpayer is in no mood to pay for more than we are doing now. Public interest is just too shallow. It won’t be performed by “commercial” firms because there is no business case for going to the Moon or Mars. The problem of radiation exposure was debated, and clearly more research is required here. Some of the panelists supported the concept of a one-way mission to Mars. These would not be suicide missions but the beginnings of permanent settlements. Others, however, said that eliminating the problems of a return to Earth stage is replaced with other, equally challenging problems of long duration survival.

Robert Zubrin (author of The Case for Mars)
Zubrin kicked off his presentation with the audacious claim that the most important issue is the world today is going to Mars. In 500 years, the first mission to Mars will be remembered more than who wins the election or how we manage our health care system. There’s some truth to that, but most people have to pay their bills first. He gave his classic talk on how to get to Mars in ten years. It is a very well thought out mission plan, and a lot of it makes sense. On the down side, Robert seems to be using the same charts and graphics from when he first came up with this concept twenty years ago. (He had grainy images from Viking to make a point about landing sites. How hard would it be to use some images from, say, the 1990s?) When it comes to destination-vs-capabilities, Zubrin is of the mind that missions drive the technology, so he wants to see a challenging mission declared. Unfortunately, this runs in the face of Andy Thomas’s observation that today’s American public is in no mood for expensive space spectaculars.

Kim Stanley Robinson (science fiction author)
Robinson’s take on space exploration was a bit more philosophical than the other speakers, as he is a writer and not a technologist. He claims that “the space project” will naturally occur as the outcome of a healthy planet and a healthy human civilization. Looking around the world right now, we’re not there. Thinking of space as a planet will help us deal with climate change. He’s not enamored with so-called “commercial” space. Space is a commons, not a playground for the rich. We need to take care of our own planet, as only Earth matters. We also have to acknowledge that we, as a species, are not “destined” for space. We are products of the Earth’s biosphere. We can attempt to take it with us, but the inter-relationships among human beings and microbiotic life (for example) is not fully understood. If we take a sterile environment with us on deep space missions, what crucial microbes will we forget?

Panel Discussion: Wilder ideas, one-way missions, warp drives, starships, etc.
This panel consisted of Sarah Walker (an astrobiologist), Ed Finn (from the Center for Science and the Imagination), Paul Davies, Kim Stanley Robinson, and Robert Zubrin. It was an entertaining discussion on such speculative topics as nuclear propulsion, space elevators, controlled fusion, magnetic monopoles, generation ships, modified human biology, etc.

Summary
There was no real conclusion or summary statement planned, but I thoroughly enjoyed the day. I spoke with Prof. Paul Davies prior to the meeting and he kindly gave me a few minutes on stage to promote local chapters of the National Space Society and the American Institute of Aeronautics and Astronautics. Some good contacts were made and I think there will be opportunities for collaboration between ASU and groups like NSS, the Moon Society, and AIAA.

As for the prospects for invigorating the space program, I believe the key word is patience. Government-run space exploration will only accomplish what citizens are demanding, and right now, not enough citizens are demanding a base on the moon or Mars. Privately sponsored space exploration might happen eventually, but it would have to be from a purely altruistic motivation, as there is no business case for exploration any time soon. We will need to wait for the technology to allow either of these paths to become affordable before we will make much progress towards establishing a true space faring civilization. That is the sad reality.
