Optical Design of an Optical Communications Terminal

This airborne system would keep itself aimed at a ground station. An optical communications terminal (OCT) is being developed to enable transmission of data at a rate as high as 2.5 Gb/s, from an aircraft or spacecraft to a ground station. In addition to transmitting high data rates, OCT will also be capable of bidirectional communications. The OCT is meant to incorporate all of the design features of a prior apparatus denoted the Optical Communications Demonstrator (OCD), plus some improvements.

NASA Technology Lets You Cook Dinner From the Office

By combining remote-control technology with the capability to cook and refrigerate food, the Connect Io Intelligent Oven lets you have dinner ready when you get home.David Mansbery used to be president of a natural gas supply company, and NASA’s Glenn Research Center in Cleveland was one of his biggest customers. With a busy schedule, Mansbery rarely had time to cook meals for his family. His idea was to create an oven that would let him cook dinner from the road. He pitched the idea of a hot-and-cold, remotely controlled oven to NASA, which supplied him with its Embedded Web Technology software.
