Happy Birthday Chris!

Not that Chris will take time to look at global spin any time soon (how’s that for a useless link?), but I thought I’d just announce that our dear boy (and new dad!) is 30 today!

I bet he’s enjoying today immensely.

We love you, Chris! Happy birthday (and a big hi to the family, too)!

Basics of Space Flight

This is more a note to myself than anything, but you might find it interesting as well. JPL has put together an overview called the Basics of Space Flight, covering topics like orbital mechanics, experiments, and communication. It’s supposed to have a bent toward unmanned missions, but a lot of the principles are the same. I look forward to reading it.
