... and, if you believe Elon Musk, anyone else who may be interested in the long-term survivability of the human race.
SpaceX is about to send a bunch (11!) of satellites into orbit, which you can watch live here: http://www.spacex.com/webcast/.
This is the first launch since their last rocket blew up, so it's important that this one, how do you say, not blow up. But even more important than that, if all goes well they're going to try to land the first stage back on the ground, standing up. This would be the first time this has been done, it's super hard, and would be a Big Deal for the FUTURE.
Anyway, it's super exciting for people like me. If you're a people like me, check it out, right now.
