Today in 1969 Apollo 12 returned to earth after visiting the moon, and if the stories are true, it brought with it a tiny tile containing line drawings by six Earth artists. Plus: since most of us aren't likely to visit the art installation on the lunar surface, maybe we can visit this museum in the Florida Keys that goes below the surface of the water.
Of all the great breakthroughs we’ve made in outer space, there are none sweeter than this: last month, astronauts on the International Space Station baked chocolate chip cookies. But baking cookies in space is a little different than baking them on Earth. Plus: a new device called the Exolung can keep air flowing for virtually as long as a diver likes.
