LA CANADA FLINTRIDGE, Calif. (AP) - One California family of five is learning what it's like to live on "Mars time" this summer.
NASA flight engineer David Oh had to switch to Martian time after the rover Curiosity landed on Mars earlier this month. His wife and three children decided to tag along to see what it is like.
A day on Mars is about 40 minutes longer than an Earth day, so they've been waking up, sleeping and eating at odd hours. One day last week breakfast was at 3 p.m.
Every mission to Mars, hundreds of NASA scientists and engineers at the Jet Propulsion Laboratory make the time change for three months. But it's unusual for an entire family to join in. The kids will be on Mars time for about a month.
