During each mission to Mars, NASA scientists on the mission follow "Mars time" for the first three months. (On Mars, each day lasts about 40 minutes longer than a day on Earth.)
David Oh, Lead Flight Director for the Mars Science Laboratory Rover Curiosity, took his wife, Bryn, and kids -- 13-year-old Braden, 10-year-old Ashlyn and 8-year-old Devyn -- on the journey into "Mars time". Each day, they pushed their schedule forward by 40 minutes, eventually waking up in the evening and sleeping during the day. Here, David and his family share their picks for around-the-clock family fun in Los Angeles.
