ROCSAT 2 (Republic of China Satellite 2) is the second high-resolution Earth observation satellite for the Taiwanese National Space Program Office (NSPO) whose mission is regional remote sensing – to collect data to be used for natural disaster evaluation, agricultural applications, urban planning strategy, environmental monitoring, and ocean surveillance. In addition, the satellite's payload will include an auroral observation instrument.
ROCSAT 2 was lifted into orbit during the mission ‘Taurus 3210 | Formosat-2’, on board a Minotaur-C 3210 space rocket.
The launch took place on May 20, 2004, 5:47 p.m. from Space Launch Complex 576E.
