Captain Kirk starts Discovery's last voyage

The shuttle Discovery has left the ISS to come home for the last time.
Today's wakeup music for the crew was the theme from Star Trek, with William Shatner intoning:
"Space, the final frontier. These have been the voyages of the space shuttle Discovery. Her 30 year mission: To seek out new science. To build new outposts. To bring nations together on the final frontier. To boldly go, and do, what no spacecraft has done before."

A fitting farewell.
