Fly-by-Wireless: A Less-Wire and Wireless Revolution for Aerospace Vehicle Architectures

By George Studor, NASA’s Johnson Space Center, Houston, TX

Every ounce of weight brought to the lunar surface costs 40 to 60 times that in fuel needed at liftoff from the Earth. Part of that weight penalty is due to wires, but ...

Compact, Highly Stable Ion Atomic Clock

NASA’s Jet Propulsion Laboratory

This high-precision clock is designed for navigation and radio science applications.

A mercury-ion clock now at the breadboard stage of development (see figure) has a stability comparable to that of a hydrogen-maser clock: In tests, the clock exhibited an Allan deviation of between 2 × 10^–13 ...

Microbial-Based Lawn-Care, Pond-Care, and Cleaning Technologies

Organica

Proprietary microbial systems use naturally occurring microbes in lieu of chemicals in fertilizers, microbial inoculants, cleaning products, and pond treatments. Products are based on incorporating beneficial micro-organisms with a variety of task-specific organic surfactants, microbial nutrients, fertilizers, cleaning agents, and bio-polymers. The micro-organisms produce enzymes that continue to work ...

Flexible Silicon Circuits Conform to Complex Shapes

Scientists at the University of Illinois Champaign-Urbana have developed a new form of stretchable silicon integrated circuit that can wrap around complex shapes such as spheres, body parts, and aircraft wings. The circuits can operate during stretching, compressing, folding, and other types of extreme mechanical deformations, without a reduction ...
