November 30, 2001 marked the first-ever transmission of an image by laser link from one satellite to another. Terminals on the European Space Agency's (ESA) Artemis spacecraft, operating 19,270 miles above Earth, and the French space agency's (CNES) SPOT 4 satellite, orbiting at 517 miles altitude, exchanged high-definition imagery data at 50 megabits per second. Images from SPOT 4 via Artemis were subsequently transmitted to the SPOT Image control center in Toulouse, France. Effective cooperation between several operations control centers ensured success. These included the CNES SPOT 4 control center and the SPOT Image data reception/processing facility in Toulouse, the ESA-Artemis mission control facility in Redu, Belgium, and the Artemis operations control center in Fucino, Italy. The main advantage offered by the optical data relay system is enhanced availability. When operated with SPOT 4, the link can be maintained for more than 50% of the orbit. This increases contact time dramatically and shortens the time interval between when images are recorded and when they are available to the customer. System potential also extends beyond Earth observation, promising to revolutionize satellite-to-satellite communications for constellations in low-earth orbit, geo-stationary satellites, and deep-space exploration probes.

By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
