What is SpaceX Dragon's secret cargo?
SpaceX has hinted that the Dragon cargoship that's due to blast off to the International Space Station on May 19 to make history as the first commercial craft to dock with the ISS could be carrying a secret payload. The last time a Dragon had a secret cargo, it was a round of cheese in homage to Monty Python.
So what do we reckon it is this time? A can of Spam? Two halves of a coconut? Something not Python-related?
