Solar/Infrared Aerobots for Exploring Several Planets

A report discusses a class of balloon-borne robotic instrumentation systems that have been proposed for use in exploring Venus, Jupiter, Saturn, Uranus, and Neptune. The balloons would be of the Montgolfier type; that is, buoyancy would be achieved through heating of atmospheric gases...

Solar-Powered Aerobots With Power-Surge Capabilities

Advanced aerobots that would be powered by solar photovoltaic batteries and that would be capable of storing energy for occasional operation during short intervals at power levels far beyond those of the photovoltaic batteries have been proposed. Aerobots are robotic balloon-buoyed airborne...

Briefs: Photonics/Optics

The figure illustrates aspects of a lightweight, relatively inexpensive solar photovoltaic module suitable for use on Earth or in outer space in conjunction with at least a...

Modulated (as opposed to steady) light can be used in the optical transmission of power to remotely located sensor circuitry in a system like that described in the preceding...

Briefs: Photonics/Optics

The figure schematically illustrates a prototype general-purpose, microprocessor-based sensor and control system in which power, data, and control signals are transmitted via...
