MarsNASA has small $18.8 million nuclear thermal rocket research project

No Comments
Last year, NASA partnered with BWXT Nuclear Energy Inc. for an $18.8 million contract to design a reactor and develop fuel for use in a nuclear-thermal propulsion engine for deep-space travel. “Significant advances in material research and technology development have …

astronomyPlasma Magnet Sails to get manned missions to Mars in 1 week

No Comments
The plasma magnet sail engine is little more than 2 pairs of charged rotating coils and is therefore extremely simple and inexpensive. A fully powered plasma magnet sail using a small nuclear power source could accelerate at 0.5G and reach …
