Video Wall Improves Collaboration

The renovated Payload Operations Integration Center, part of the Huntsville, AL-based Marshall Space Flight Center, features a new video wall. The wall includes a 2 × 12 array of monitors that uses RGB Spectrum’s OmniWall 32 Display Processor to route and display up to 32 input signals. The processor expands the ability of operators to share information in real time, such as live video feeds, diagrams, photographs, results of experiments, and information on power usage.

Solar Sail Will Demonstrate “Propellant-less Propulsion”

The Sunjammer Mission team — including NASA, lead contractor L’Garde, Space Services Holdings (SSHI), and Micro Aerospace Solutions — is preparing to launch Sunjammer, the largest solar sail ever deployed, named in honor of legendary science fiction author Sir Arthur C. Clarke. In a 1963 novella, Clarke christened a solar sailing ship “Sunjammer,” powered only by the pressure created by photons from the Sun.

Using CVD Diamond to Cool Hot Devices

Increasing power densities and decreasing transistor dimensions are hallmarks of many of today’s semiconductor devices, including high-voltage power transistors, laser diodes, and RF power amplifiers. GaN devices, such as power converters for photovoltaic cells and cellular base-station power amplifiers, are further enabling higher power densities in smaller die sizes. Both trends are significantly increasing the thermal management challenge within the chip and surrounding package or module.
