The sound in Saturn's rings

October 16, 2012 4:41 pm | by EurekAlert! | News | Comments

Due to their special properties, dust acoustic waves can propagate inside these plasmas like sound waves in air, and can be studied with the naked eye or with standard video cameras. Physicists have published a model with which they describe how large amplitude dust acoustic waves in dusty plasmas behave.

What to look for in relays for space applications

October 11, 2012 9:34 am | by Karl Kitts, Engineering Director, High Performance Relays, TE Connectivity | Articles | Comments

When NASA’s Curiosity rover made a perfect landing in Gale Crater of Mars, it was 150 million miles from the nearest repairman. Every component has to operate reliably to support the vehicle’s expected operation life of 98 weeks—or one Martian year. Specifying a relay for space obviously involves finding a compact, lightweight device that meets electrical needs.
