Nagin Cox's speech, called 'What time is it on Mars?' talks about the unlikely effects of working to expand human colonies outside of the planet Earth.
Cox is a spacecraft engineer at NASA's Jet Propulsion Laboratory, who has worked on three of the four rovers that have been sent to Mars – she is described as a "first-generation Martian" as a result. Rather than discuss the details of her job, Cox talks about its unlikely effects – namely the effects that is has on people's schedules. A day on Mars is called a 'sol' and is 24 hours and 40 minutes long – making it so that people who control the Mars rover on the night shift (from Earth) have to wake up 40 minutes later than the day before, each day, in order to keep up with the night schedule of the rover on Mars.
This unusual scheduling has some unique consequences that are both positive and negative, as Cox explains in her quirky keynote.
