I finally got around to watching The Martian. My husband rented it for me, since he saw it in the theater with our son, while I stayed home and babysat our dogs.
What a cool movie! That must've taken years of research, alone, to figure out how to do the calculations for some of those things.
If you haven't seen it, go rent it right now. Don't sit there and read this, go rent that movie and watch it. You'll be glad you did!
Have a great week!
