...rockets look. Most scientific judgments about them have been pessimistic. Rocket motors develop their thrust by burning fuel with an oxidizer and expelling the products of combustion at high speed through a tail pipe. The energy of combustion is necessary to make the gases move fast, but the mass (weight) of the gases is also necessary. No mass, no thrust...
There are ways of getting around this failing of nuclear rockets. The most obvious is to take along a stock of material that can be gasified by the nuclear heat and shot out the tail at great speed. The trouble with this solution, of course, is that the weight of the material may make the nuclear rocket hardly more efficient than a chemically fueled one. In addition, a heavy shield must be carried to protect the crew from nuclear radiation...
...light of God's grace as the permanent futurity of God which is always there before man arrives, wherever it be, even in the darkness of death. Paul can certainly speak of a glory which is ready to be revealed for us, of the eternal 'weight of glory' which awaits us. But at the same time he speaks of faith, hope and love as things which will not cease . . . In other words . . . the openness of Christian existence is never-ending...
Another use will be in "Big Brother" reconnaissance satellites now in the planning stage. If they get electricity for working their television transmitters from small nuclear reactors, as has been proposed, they will need radiation-resistant tubes. Every gram of weight counts on a satellite. Big Brother will have no grams to spare for heavy shielding...
