Gamma Ray Laser and the Million MPH Spacecraft
I have 2 min on this computer, but:
Gamma Ray laser research can relate to the Million MPH Spacecraft http://www.thefreelibrary.com/Pumpin...aser-a04539152 http://www.ucsusa.org/nuclear_weapon...weapons-a.html **************** http://1mmph.yolasite.com/ |

The idea of a spacecraft that travels at an average speed of one million mph would be a boon to solar system exploration. But sources I see propose you need a specific impulse of a million seconds and that while this is possible, it does not come from sources that might have been expected to produce such thrust. Solid. liguid and even geseous core, nuclear fission rockets aren't expected to produce Specific Thrust (I'll use the term Isp) of more than several thousand seconds. Even plasma-fusion rockets would get only to 200,000 seconds according to sources. It begins to look like a job for antimatter and/or induced gammray emission (IGE)/gamma ray lasers. http://www.hafniumisomer.org/cqeseg3.htm Exhaust velocity of the particles leaving the exit nozzle is important and if that velocity is the speed of light because the exhaust particles are gamm rays, then a low ratio of fuel to payload weight is available. Other antimatter schemes might be workable but the electron/ anti-electron (positron) annhilation produces said gamma rays. Redirecting them to the rear of the craft is a problem; possibly that's where the gamma ray laser comes in. |

Obliteration of dust and micrometeorites that could otherwise cause trouble to a million mph spacecraft. |
