Mercury is in retrograde—this is evident based on pretty much everything that's happened over the last few weeks. But on Sunday, Mercury will go direct, just as Mars moves directly opposite the sun—which I'm sure means a whole bunch of gobbledygook in Horiscopese, but also means we're getting a pretty swell view of the Red Planet this weekend.

According to the American Museum of Natural History, Saturday May 21st is perfect for Mars-watching, which is closer to us now than it's been in a decade. We're lucky enough to get a blue moon and a red planet on the same night, since we're getting an extra full moon this weekend—AMNH suggests, though, that you try to block out the light from the moon with your hand so Mars isn't overshadowed by all the flashlight-bearing moon men, which is a thing, I am sure.
Anyway, here are some more thoughts on Mars.
