Timekeeping beyond Earth: Nasa wants to come up with a new clock for the moon

Nasa wants to come up with an out-of-this-world way to keep track of time, putting the moon on its own souped-up clock. (Photo/Agencies)

It's not quite a time zone like those on Earth, but an entire frame of time reference for the moon. Because there's less gravity on the moon, time there moves a tad quicker — 58.7 microseconds every day — compared to Earth. (Photo/Agencies)

So the White House Tuesday instructed Nasa and other US agencies to work with international agencies to come up with a new moon-centric time reference system. (Photo/Agencies)

“An atomic clock on the moon will tick at a different rate than a clock on Earth,” said Kevin Coggins, Nasa's top communications and navigation official. “It makes sense that when you go to another body, like the moon or Mars that each one gets its own heartbeat.” (Photo/Agencies)

The last time NASA sent astronauts to the moon they wore watches, but timing wasn't as precise and critical as it now with GPS, satellites and intricate computer and communications systems. Those microseconds matter when high tech systems interact. (Photo/Agencies)

Last year, the European Space Agency said Earth needs to come up with a unified time for the moon, where a day lasts 29.5 Earth days. (Photo/Agencies)

The International Space Station, being in low Earth orbit, will continue to use coordinated universal time or UTC. But just where the new space time kicks in is something that Nasa has to figure out. Even Earth's time speeds up and slows down, requiring leap seconds. (Photo/Agencies)
