Today I Learned: 1) ...how to mount a router to a wall, and how to staple cables around the edge of a room. 2) Elderberry juice is really tasty -- it's kind of like a slightly sour white grape juice, with similar rich, deep hints of grapiness, for lack of a better word. 3) A nuclear thermal rocket is a rocket design powered by gas (usually hydrogen) heated by a nuclear reactor. The rapid expansion of the gas fuel as it is heated causes it to shoot out the back, providing thrust. Nuclear thermal rockets haven't really been used in spacecraft, but they are predicted to be pretty expensive and generate less thrust than traditional rockets, but should also be lighter and much more fuel-efficient. Nuclear thermal rockets are not to be confused with nuclear pulse propulsion, which propels a rocket by exploding small nuclear warheads behind a blast-resistant shield.
