When it comes to emerging industries like extraterrestrial resource mining, customary international law can seem like attempting to herd cats in zero gravity. Pinning down what is “fair” and “customary” in areas where no man has gone before can seem daunting but it also presents the unique opportunity to shape international custom by establishing them.

On May 22, the Space-X Falcon rocket with its cargo capsule on top launched from Cape Canaveral and reached orbit ready to dock with the International Space Station. So far everything is going perfectly. It’s a huge step. Congratulations to Space-X, Elon Musk and his team.

The upcoming rare transit of Venus is one step in a long dance among Earth, Venus and the Sun. Transits of Venus follow a peculiar pattern—two transits 8 years apart, then 105.5 years with no transits, then two transits 8 years apart, then 121.5 years with no transits, for a total cycle of 243 years—and thereby hangs a tale.

Cassini obtained its first high-resolution images of Methone on May 20, 2012. Methone is one of the smallest regular moons of Saturn, having a diameter of only about 3 kilometers. It was the first moon that Cassini discovered, very early in Cassini's mission at Saturn, in 2004.
