Mars rover team coming off ‘Mars time’ UPI

Researchers operating NASA’s Mars rover Curiosity, after three months of living on “Mars time,” have switched to more regular hours, the space agency says.
The Curiosity team at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., has been working on a schedule based on martian day, called sols, which are about 40 minutes longer than Earth days.
That’s meant the start time of their work day has been moving a few hours later each week, often resulting in the team working overnight hours on Pacific Time.
