Why we should(n't) go to space -- Kim Stanley Robinson

Here's Kim Stanley Robinson, author of the stupendous Red Mars books, in the Washington Post explaining why we shouldn't go to space -- and why we should.

The creation of a cosmic diaspora is just one argument for putting humans in space -- a bad one. But now, as human-made climate change has thrust us into the role of stewards of the global biosphere, new reasons, good ones, have emerged. Indeed, keeping our space ambitions relatively local -- within our own solar system -- can help us find solutions for the climate crisis.

It has been said that space science is an Earth science, and that is no paradox. Our climate crisis is very much a matter of interactions between our planet and our sun. That being the case, our understanding is vastly enhanced by going into space and looking down at the Earth, learning things we cannot learn when we stay on the ground.

Studying other planets helps as well. The two closest planets have very different histories, with a runaway greenhouse effect on Venus and the freezing of an atmosphere on Mars. Beyond them spin planets and moons of various kinds, including several that might harbor life. Comparative planetology is useful in our role as Earth's stewards; we discovered the holes in our ozone layer by studying similar chemical interactions in the atmosphere of Venus. This kind of unexpected insight could easily happen again.
