Today I Learned:
1) Many Chinese dishes are named after a story or metaphor. For example, there's a Sichuan noodle dish called "ants climbing up a tree" because it kind of looks like that.
2) NASA plans for any manned missions to Mars to run on a vegan diet. Why? Because animal products go bad too quickly, and animals are too inefficient to cultivate on-ship.
3) Speaking of NASA, NASA is planning a mission to capture an asteroid and move it to the moon. The idea is to park it in lunar orbit until around 2020, when a manned mission can go retrieve samples and bring them back. This mission will also test some key technologies for removing dangerous asteroids in the future, in case NASA or an equivalent agency ever gets the money to be able to detect city-destroying asteroids in time to launch a mission to stop it. (Right now we can probably detect extinction-event-level asteroids, but not city-busting ones)
