I woke up late after getting home from my meeting late, got my coffee late, and now have a caffeine headache. So you’ll forgive me, I hope, if I simply point you to my friend Emily Lakdawalla’s blog about new images from Mars. These are pretty cool. She asks you to look at the images and try to see what’s funny about them before she actually tells you. I’m proud to note that I saw what was going on right away, but I didn’t know the cause. Without my headache I might have figured it out in time, of course. Coffee jonesing can ruin the scientific process.
