How large is GALEX?
GALEX weighs only 280 kilograms (a little over 617 pounds). It is 2 meters (6 feet 6 inches) tall and, with its solar panels unfurled, it is 2.8 meters (9 feet) wide. It was designed to fit into the nose cone of the Pegasus launch vehicle and so began its journey with its solar panels wrapped around the spacecraft. So until it reached orbit around the Earth it was only 1.1 meters (3 feet 8 inches) wide.
