Following separation, the Falcon 9's first stage is hopefully going to return and land on SpaceX's pad at Cape Canaveral. As we pointed out yesterday, the land-based return is fairly unique and means that we'll get high-quality video of the event that isn't normally possible with drone ship landings. It's also another milestone on the road to Elon Musk being able to boast of saving a small fortune on space travel with his reusable rockets.

Update: Success! The first stage has successfully landed back in Cape Canaveral.
