Space Review comment: A Nuclear Thermal Rocket, for fantastic expense, roughly doubles the Isp of chemical rockets…using a source of energy literally one million times more powerful. Stan Ulam, who is sometimes credited with being the real father of the hydrogen bomb, considered this problem and realized it is difficult just keeping a chemical rocketContinue reading “A Nuclear Free Earth”

The shiny starship is certainly a cultural symbol of neoliberal ideology now. It reflects the idea that these John Galt/Howard Roark/Tony Stark entrepreneurs can make a better world. A world like a science fiction novel or comic book. Like the Saturn V showing the rest of humankind the power of American capitalism by defeating theContinue reading “SpaceX”

A “true” Space Station provides a Near Sea Level Radiation 1 Gravity (NSLR1G) environment for long duration missions Beyond Low Earth Orbit (BLEO). DosingContinue reading “Last Comments…maybe”

The video spokesperson said they are a decade away but in reality, this was available a half a century ago. Star Wars directed energy research likely increased the efficiency greatly, but that data is of course, classified. Helicity knows this and the fusion reactor stuff is all fundraising when it is actually going to beContinue reading “Helicity”
