Like NASA rover, family switches over to Mars time

In this photo taken Tuesday, Aug. 14, 2012, Devyn Oh, 8, flips around a sign reading: "Flight Director Sleep on Mars Time, Come Back Later," posted on their front door for his father, David Oh, a flight director of NASA's latest Mars mission, at their home in La Canada Flintridge, Calif. The Oh family has been living on Mars time and following an odd schedule ever since the NASA rover Curiosity landed in an ancient Martian crater on Aug. 5. Ashlyn Oh and their mother Bryn look on.
