  1. Personally, I believe that application of nuclear power in space would be very much in our interest. Not only do nuclear thermal rockets offer a major improvement over existing propulsion technologies, but the use of nuclear reactors as power sources for satellites, space probes, and the like could allow for much greater scientific return or utility. However, I realize that nuclear power does have associated risks, and there are others who may feel different. Whether you are for or against the usage of nuclear power in space, I am curious to hear your opinions. For reference, here's an int

  3. 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. https://en.wikipedia.org/wik
  4. The Soviets did a lot of good things with their space program. The R-7 was the first and still is one of the best satellite launchers, the Venera probes were cool and got us a lot of data, the RD-180 gets high performance through weird metallurgic sorcery, etc. Unfortunately, a lot of the stuff they did was also crap. Stuff like the N-1 comes immediately to mind, but there were others. Let's take a look at Vostok, the first manned spacecraft. It is commonly compared to the American Mercury spacecraft. Both had similar purposes; to get a man into space, keep him there for a short time, and

  6. 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. How
  7. First, there was the Antares rocket explosion, and now SpaceShipTwo has crashed, killing 1 pilot. It seems the craft exploded after lighting the engine. Test flights are always a risk. Growing up as the brat of a test pilot, this has always been on my mind during these sorts of things. Post more details here as they become available.
