A bit off-topic sorta here, but, IRT all those people complaining about human activities "killing the earth" and making animals and things go extinct. These people will go on about how "we need to take care of our planet instead of spending all of this money on space," as if it's some sort of zero-sum game where all 7 billion human beings must only concentrate on one thing and can't have different careers and fields of specialty. đHumans are fucking amazing, how cool is it that we can capture such an event and that we can now successfully change the orbit of an asteroid....
What a time to be alive....
But the ironic thing is, life on this planet is entirely finite. Life only has about a billion years or so at most. Advanced life less than that. The ONLY chance terrestrial (earth-based) life as we know it has ever had, and ever WILL have, IS humans. And even more ironically, the destruction we have wrought on this planet....the space program can and does fix with the development of newer and better technologies. Especially with advanced materials science, such as better insulating materials that increases cost savings on energy. Our satellites have gathered a TON of data on the albedo effect of the earth, and have come up with a very near-future solution to install highly reflective materials on the rooftops of city buildings, which would reduce the effects of sunlight absorption.
