For SpaceX founder Elon Musk, it might as well be: if at first you don't succeed, try, try again and again ... and again.
In its fourth attempt and after months of delays, SpaceX's Falcon 9 rocket took off from Cape Canaveral, Florida, on its way to deliver six commercial satellites into orbit Monday.
The launch was at least halfway successful. It was partly meant to test whether SpaceX could reuse its rocket boosters, and that portion of the project didn't fair so well.
Musk tweeted that even though most of the systems worked, the boosters were destroyed at splashdown. Or, as he puts it: "aka kaboom."
