    NASA NASA's crazy mars idea!

    It is much easier to build the station over there, after we have an areoestrial base. Sending a station from Earth-orbit to Mars-orbit is pretty damned expensive, fuel-wise and economically. The gravity well of Mars is much less steep than ours, meaning less fuel (and less cash!) is needed to...

    Does anyone have any liquid fuel rocket plans?

    I would advise you to take -extreme- caution when building liquid-fuel rockets. When, not if, something goes wrong, you'd best be behind sturdy concrete. John Carmack is and he has plenty of information regarding the construction of rockets...

    New Shuttle concepts from Europe

    Funny, I always thought that the main cause of trouble has been the shuttle-orbiter. It is mostly useless, dead weight. Get rid of the orbiter, you get rid of a whole series of problems. This is a very interesting consideration. If the boosters exploding is your concern, notice that the...

    Solid Rocket Fuel

    I dabbled a little in solid-fuel rocketry. I managed to make a compressed form of potassium-nitrate from TreeStump Remover(™) and confectioners sugar, but I opted for a simplistic uncompressed mixture of both chemicals in the end. The flexibility of nitrous oxide as an oxidizer is stunning...

    Space Shuttle moon orbit

    This looks promising. Indeed, the elimination of the orbiter vehicle itself seems to be quite an advantage. With the SRBs you have a nice Apollo-esque man-rated launcher, not to mention heavy lift capability that rivals the Saturn V. Is it just me or did Luna and Mars just get closer...

    RTG Plans needed.

    Pursue it? Hah! I'd need to have access to nuclear facilities, not to mention ludicrous amounts of money. I started this topic more than a year ago, in a time when I was naive and didn't understand how complicated such a device was. I'm surprised this topic is still going strong, despite my long...

    Giant nuclear powered combustion engine

    You could consider Project ORION a nuclear-piston engine, without the engine-proper. :tongue:

    What would cause a black hole to explode?

    If I recall correctly, the only thing that can make a black hole explode is another black hole. I am unsure of the parameters, or the variables involved, but I'd guess they would have to be around the same size. Hmm. I'm wondering if 1-dimensional singularities (cosmic string) will do the...

    Waves in Space

    Space is space. Mechanical/acoustic waves cannot travel through a lack of material medium. I'll avoid an obvious cliche.

    Voyagers - - you're fired?

    Cheer up! Vacuum is great for long-term storage, and I sure hope that by the end of this century someone will catch up to the Voyagers and Pioneers and give them each a swift relativistic kick in the rear.

    Heat Death

    If there is Zero-Point-Energy, no. I need to check that up myself.

    Heat Death

    I've been reading some of Stephen Baxter's Manifold and Xeelee Sequence stories, and quite a few of them deal with the "upcoming" Heat Death. What a depressing future. Personally, I've always felt a bit skeptical about the Heat Death. Although the surviving particles are still rather far...

    Need help to propulse a small bolid

    What exactly is a bolid? Is it some sort of vehicle? If so, then read the following text. If not, ignore everything I said. A small CO2 cannister will work, though I'd recommend you have someone qualified to supervise your integration of the can into your bolid. Mind that CO2 cans should...

    Space Shuttle moon orbit

    Sounds a lot like Moonseed, by Stephen Baxter. His novel has a desperate trip to the Moon in only a matter of weeks, using current-market rockets and equipment. I'd suggest giving it a read. I would also recommend looking into nuclear pulsed propulsion. There is a book by George Dyson (son of...

    Non-defense Aerospace jobs?

    Burt Rutan of Scaled Composites runs a civilian aerospace firm out in the Mojave, and he just recently won the X-Prize. I am unsure if he is hiring, but it might do you well to take a look into it. In fact, I think most of the former X-Prize competitors are worth looking into: Non-military...

    Nuclear Thermal Rocket Engines

    Wrong. What I know is that the H2 is propellant. There is a difference between fuel and something one propels. The modern chemical rockets and theoretical antimatter drives are the only propulsion systems that utilize chemicals as both fuel and reaction-mass. Once again, H2 is not the...

    Nuclear Thermal Rocket Engines

    Who says that chemicals are used as fuels? Show me a source where it says that nuclear fission and/or fusion use liquid hydrogen as fuel. Antimatter propulsion is excluded in this case, due to the fact that some varients of the design require ice or hydrogen. Furthermore, there is a NERVA...

    Scientist Sees Space Elevator in 15 Years

    Um, no. The US has made multiple spacecraft capable of circling the Earth. The Shuttle has been our most recent one, and the ISS follows an orbit that passes over the North American continent as well as Eurasia. Both complexes can go around the entire planet in the time it takes to watch a...

    Casimir Effect and Inertia

    Generally, a Casimir-engine is a device for the production of exotic matter/negative energy, which can lower the inertial mass of an object, through the utilization of the Casimir Effect. Now, should the negative energy seek the inertially weak center of a centrifuge, or should it cause some...

    Casimir Effect and Inertia

    A theoretical question on a known effect: Suppose one were to make a Casimir-engine for the production of negative energy. If one placed said engine in a spinning centrifuge on the International Space Station, would the negative energy repel the centrifugal effect, and rise to the weightless...

    Questions for a Robotic Engineer

    Is A Nuclear Reactor A

    Fission reactions work by the process of neutrons stimulating atomic nuclei. An RTG gives power by "dying" isotopes, which are already unstable. The isotopes' short lives generate a low amount of power, which is good for passive space probes in areas of low solar intensity. In either type of...

    Is A Nuclear Reactor A

    As far as I know, controlled fission reactors are completely legal in space. The Partial and Outer Space Test Ban Treaties stated that no nuclear weapons or explosions were permitted from the upper atmosphere and the heavens themselves. It sickens me to see so many "treaties" hampering human...

    I think I have an idea

    By Jove, what's happened here? Esran, I was merely providing a sense of comedy and common sense. It was rude of me at the time, but I DID tell you I knew of that. I was an ass to you, but I was kidding around. I don't want any further conflict between myself and your own cyber-psyche...

    New Ideas for shelding:manned deep space Missions

    I believe an electro-static "aegis" would be perfect for protection against cosmic rays and solar flares. We're quite advanced enough in electrostatics to start a new engineering feat that could benefit highly for the space-faring homo sap. How could it work? You could charge up an...
