[Satellite TODAY 05-10-13] The Radarsat-1 Earth observation satellite, built by Ball Aerospace & Technologies for the Canadian government, has concluded its mission after serving the organization for more than 17 years – 12 years longer than its mission life. Radarsat-1 was launched in 1995 for an expected five-year mission. It was Canada’s first and oldest Earth monitoring satellite and conducted the first complete radar survey of the Antarctic continental ice shelf that helped monitor the effects of global climate change.

Ball Aerospace built the spacecraft bus and a portion of the ground station for the advanced operational synthetic aperture for Spar Aerospace and the Canadian Space Agency. Ball also provided technical services to Spar (MacDonald Dettwiler), including system engineering and system integration planning.

This satellite represented several firsts for Ball Aerospace: first fixed price and commercial spacecraft bus, introducing a cost-effective solution for Earth observation and remote-sensing missions; first Ball Aerospace international spacecraft, which expanded the company’s profile into new markets; inaugural satellite bus for the company’s successful Ball Configurable Platform (BCP) line of spacecraft.

"Radarsat-1 set the bar high," said Cary Ludtke, vice president and general manager for Ball’s Operational Space business unit. "It was a great learning experience in principal areas of the company’s evolving business approach, particularly in developing the know-how to execute on commercial, fixed-price programs."

By circling the Earth once every 101 minutes, Radarsat-1 relayed images for use in resource management with details about the Earth’s geologic features, oceans, ice, weather and vegetation. The satellite’s synthetic aperture radar instrument acquired images of the Earth, day and night, in all weather and through cloud cover.
