Associated space launch
ARGOS (Advanced Research & Global Observation Satellite) is a testbed and demonstration program for advanced remote sensing technologies for the US Air Force's Space Test Program (STP). ARGOS's primary objective is to fly and operate advanced payloads that include two technology demonstrations and seven experiment payloads for global and celestial observation. ARGOS also has a goal of three years of on orbit operations to demonstrate and collect science data for the Earth's global environment and top priority military space programs.
SUNSAT was lifted into orbit during the mission ‘Delta II | ARGOS’, on board a Delta II space rocket.
The launch took place on Feb. 23, 1999, 10:29 a.m. from Space Launch Complex 2W.
