Ten tips for smart battery implementation

August 7, 2012 4:47 pm | by Adam Hickerson, Raveon Technologies, | Blogs | Comments

Smart battery design starts with knowing the details of the system that is using the battery power. A battery does not make a system battery-powered. For operational lifetimes measured in days, weeks or years, power must be a design consideration from the ground up.

The Golden Touch: Behind the Webb Telescope

August 7, 2012 4:06 pm | by HubbleSiteChannel | Videos | Comments

The Webb Telescope's mirrors are coated in an extremely thin film of gold. This gold layer, only a few millionths of an inch thick, enables the mirrors to best reflect the infrared light the telescope seeks. The thinner the layer, the better off the telescope will be -- every bit of weight counts when a telescope as big as Webb is being lifted into space by a rocket. Join us at Quantum Coating in New Jersey, where engineers are vaporizing gold to apply a thin, even layer to the telescope's mirrors. - HubbleSiteChannel
