Printing outposts on the Moon is all the rage for mission planners. And if they succeed, we will all feel the benefits here on Earth.

A passive, cramped fly-by of Mars just to say we did it is a terrible, no good, very bad idea.

Tracking the speed of an event horizon can tell us what a black hole ate, give us a clue as to how it was formed, and whether it survived a major collision.
