Unfurling a Big Antenna in Space

The ICO G1, launched last month, is referred to as the "world’s largest" by manufacturer Space Systems/Loral:

ICO G1 is a Loral-designed spacecraft that incorporates a 12-meter antenna reflector designed and built by Harris Corporation. The reflector utilizes a gold-plated mesh reflective surface and a unique new Harris design that allows a very large antenna reflector to stow safely and easily on the Loral 1300 satellite platform. The reflector size enables the increased performance typically required for mobile interactive media services.

ICO G1 is the largest commercial satellite launched to date, weighing nearly 15,000 pounds at liftoff, and measuring more than 27 feet high and over 100 feet wide, following solar array deployment.
