It will be a long time before we have flight that run【C7】______ to human colonies on the moon or on one of the planets.

Great problems must be solved【C10】______ we could send colonies out into place. The distances that must be【C11】______ and the length of time it takes to do that can hardly be【C12】______ .

Finally, on the most practical【C18】______ , there has to be enormous expense【C19】______ in space exploration.
