 How cool is this: SpaceX have launched a spaceship into Earth orbit and successfully brought it back! Wow, that's amazing; a clear precursor to manned flight into Earth orbit. Congratulations to them, and most especially to my onetime colleague and friend Elon Musk, who founded SpaceX in 2002 and has invested a ton of his own money in its success.
 You might think SpaceX must be doing things similar to NASA and the ESA, in order to get these results. And of course the science is the same. But they are a little different too; these launches cost less than 1/10th of a comparable mission sponsored by a government agency. And for this particular mission the payload was ... a large round of cheese :)
