FORMOSAT-2 made successful contact with Taiwan Ground Station

新聞出處:NSPO 2004/05/21

At 1:47 A.M. of May 21, 2004 (Taipei time), when people in Taiwan and the United States began the countdown simultaneously, FORMOSAT-2, the high resolution remote sensing satellite developed with the participation of Taiwan's scientists, was launched from Taurus Rocket at Vandenberg Air Force Base in California and placed o nto orbit successfully. According to the data sent back from the launch vehicle, FORMOSAT-2 was separated from the rocket 15 minutes after the launch, and went into temporary orbit at 73 7 kilometers (4 60 miles) above ground. An hour and 14 minutes after the launch, FORMOSAT-2 completed its first telemetry feedback to the supporting ground station in Kiruna, Sweden. After the launch, Orbital Sciences Corporation, the company in charge of the launch mission, relinquished control to Taiwan's mission control center.

One minute before the launch, when the commander at the mission control declared the initiation of the countdown, the audiences in both Taiwan and the United States watched through live broadcast as the counter went down to zero. Then, at the exact moment the counter went to zero, the engine of the Taurus rocket was ignited and was launched successfully, and crowds at both places burst into cheers. At NSPO's ground control center in Hsin-chu, Taiwan, Former NSC Chair Dr. Wei , accompanied by Dr. Lee, Director of the National Space Organization (NS PO ) and hundreds of distinguished guests, watched as the rocket carrying FORMOSAT-2 went into the sky. Meanwhile, at the launch site in Vandenberg Air Force Base, Deputy Minister Ching-jyh Shieh of NSC observed the launch with members of an official delegation from Taiwan, hundreds of overseas Taiwanese , and people representing businesses involved in the FORMOSAT-2 project.

FORMOSAT-2 was developed through four years of hard work. Once in orbit, the satellite passes over Taiwan twice a day. After launch, Early Orbital Operation, a four-phase process that is expected to last a month, was initiated. F or the first phase, the condition of the satellite is closely monitored, and adjustments will be made if necessary. In the second phase, adjustments to the secondary sub systems in the satellite will be made so that it could be ready for orbit transfer. T he third phase, orbital adjustment is commenced as the satellite transfer from temporary orbit to operational orbit. F or the fourth (and final) phase, FORMOSAT-2 will unlock its remote sensing camera and upper atmospheric lightning imager and prepare those instruments for designated mission . All function tests of the satellite are expected to be completed within a month, and then FORMOSAT-2 will begin its nominal operation: 5-years o bservation through remote sensing and investigation of upper atmospheric lightning.
