How Does This Board Feel About Robert Zubrin?

Recommended Posts

For those of you who are not familiar with him, Robert Zubrin is an American aerospace engineer and author of some note. He is probably best known for his advocacy of the 'Mars Direct' proposal, although he's also done quite a bit of work in the nuclear spacecraft propulsion field (he's the guy that came up with the NSWR). His wiki page says he's also written on other vaguely political topics, but I'm not familiar with them.



Personally, I find his work on spacecraft propulsion highly interesting, and it's good that we've got somebody putting forth cogent ideas for space exploration. However, I feel that some of his ideas are a bit too optimistic, especially in regards to his Mars Direct approach. I feel that it would be more optimal to gain more experience with long term off-planet living in a location such as the moon before proceeding to Mars, while also using that time to mature techniques such as nuclear rockets to actually get to Mars. On a related note, I showed his NSWR paper to a guy I know who has some not insignificant knowledge of nuclear physics, and he was a bit skeptical. Still, in my opinion, it's infinitely better to have somebody be a bit overoptimistic about how well their ideas will work, and keeps push them forward, then a bunch of limp wristed pessimists who are afraid to send anyone beyond LEO because it might cost a few million dollars.

My friends who are more inclined to delve into details of rocketry generally consider Zubrin to be insane, but I must admit greatly liking the idea of a propulsion system whose principle revolves around containing a nuclear explosion within a shielded vessel and spurting the resulting energized propellant out of the rocket's ass.

      There's a shitload of real estate in the solar system, and we don't know much about most of it. What unmanned probes would you like to see built to learn more about the planets and other objects?
      My first choice is an Enceladus orbiter/lander; it's one of the best candidates for extraterrestial life, has confirmed cryovolcanism, and organics have been found near it. Plus, any mission you send there can get some bonus science of Titan and other cool places in the Saturn system.
      I also like FOCAL, just for the sheer audacity of it.

      I propose a new topic to regroup information about French AFVs.
      Days after days, information is overwhelmed under the inflow of photos about anything and everything.
      It can be interesting to try to have dedicated topics to ease the quality of exchanges. 
      So, if you have already posted interesting photos, documentations and view about French AFVs, you can quote them here.

      Metal cooled reactors have several advantages over pressurized water reactors. For one, their power density is greater, additionally, the coolant is unpressurized, improving safety.
      However, there are some downsides. The Soviets' Project 705 class submarines were powered by liquid metal reactors utilizing a lead-bismuth alloy as coolant. This alloy had a freezing temperature of roughly 400K. As a result, the reactors had to be run constantly, even while the submarines were in port (there were facilities to provide superheated steam to the reactors while the subs were docked, but they broke down and were never repaired). This reduces the lifetime of the reactor. Another coolant choice which has been used operationally is NaK (Sodium-Potassium). This alloy is liquid at room temperature, but reacts violently with water or air. I'm not an expert, but this seems like a bad thing.
      It seems to me that if appropriate coolants could be found, it seems that liquid metal fast reactors could see more widespread acceptance. To my untrained eye, gallium looks like a good choice. Its melting point is relatively close to room temperature (~303K), and the boiling point is quite high (over 2600K). Also, gallium is less reactive than sodium or other alkali metals. It appears that there has been some research on this topic: http://www.sciencedirect.com/science/article/pii/S0149197000000640(unfortunately, the article is behind a paywall), and it looks quite promising.
      Anybody have any opinions on this, or suggestions for alternative coolants?
