NASA To Test New Atomic Clock

edesio writes "Many satellites and spacecraft require accurate timing signals to ensure the proper operation of scientific instruments. In the case of GPS satellites, accurate timing is essential, otherwise anything relying on GPS signals to navigate could be misdirected. The third technology demonstration planned by NASA's Jet Propulsion Laboratory is the Deep Space Atomic Clock. The DSAC team plans to develop a small, low-mass atomic clock based on mercury-ion trap technology and demonstrate it in space."

Atomic? That means radiation right?

I'm not so sure that I can support anything radioactive while the poor people in Japan are dealing with their atomic disaster and remember Chernobyl? people can't live there anymore. All because of atomic clocks
