FORMOSAT-2, the nation’s first locally developed ionospheric research and surface mapping satellite, has been decommissioned after 12 years in operation.
The satellite had remained operational eight years past its expected lifespan of five years, but a series of equipment failures finally forced the National Space Organization (NSPO) to pull the plug.
One of its four reaction wheels, which rotate and position the satellite, malfunctioned in 2013, and another one stopped working in June, which meant FORMOSAT-2 could no longer take pictures or make observations, the agency said.

After weeks of repair efforts, the NSPO determined that the problematic wheels could not be fixed and that FORMOSAT-2 had to be retired.
The agency made its last contact with FORMOSAT-2 during a decommissioning ceremony on Friday at its headquarters in Hsinchu, bringing an end to the nation’s most successful surveillance satellite program.
“With gratitude, we congratulate FORMOSAT-2 for the service it provided. It accompanied us over the past 12 years as we grew up. It is like an old friend, or more like a teacher,” NSPO Director Chang Guey-shin (張桂祥) said. “The satellite made an unparalleled contribution to the nation’s space development.”
The satellite, which cost NT$4.6 billion (US$145.5 million at current exchange rates) to build, was launched on May 21, 2004, from Vandenberg Air Force Base in California.
It circles the Earth once every 103 minutes and passes over Taiwan twice a day.
It was the nation’s only satellite with a daily revisit capability, meaning it could take pictures of a given location every day, and the only one that could photograph the polar regions.
The satellite took about 2.55 million pictures of the Earth’s surface.
The pictures brought in about NT$600 million in revenue, while images worth about NT$1.1 billion were provided to 191 government agencies and 176 academic institutions in Taiwan free of charge.
The satellite helped with scientific research, environmental monitoring, urban planning and natural disaster prevention and evaluation.
FORMOSAT-2 was used in 343 disaster response missions, providing authorities with immediate images of damaged areas during the Indian Ocean earthquake and tsunami in December 2004, Hurricane Katrina in the US in 2005, the Sichuan earthquake in China in 2008, Typhoon Morakot in Taiwan in 2009 and the Tohoku earthquake and tsunami in Japan in 2011.
For eight days after Morakot hit Taiwan, the satellite took detailed pictures of all areas damaged by the typhoon to help the government evaluate the situation and plan its emergency response.
FORMOSAT-2 was also the first satellite to observe the transient luminous event — an electrical-discharge phenomena well above the altitudes of normal lightning and storm clouds — and its observations have been cited in numerous academic research.

POLITICAL AGENDA: Beijing’s cross-strait Mid-Autumn Festival events are part of a ‘cultural united front’ aimed at promoting unification with Taiwan, academics said Local authorities in China have been inviting Taiwanese to participate in cross-strait Mid-Autumn Festival celebrations centered around ideals of “family and nation,” a move Taiwanese academics said politicizes the holiday to promote the idea of “one family” across the Taiwan Strait. Sources said that China’s Fujian Provincial Government is organizing about 20 cross-strait-themed events in cities including Quanzhou, Nanping, Sanming and Zhangzhou. In Zhangzhou, a festival scheduled for Wednesday is to showcase Minnan-language songs and budaixi (布袋戲) glove puppetry to highlight cultural similarities between Taiwan and the region. Elsewhere, Jiangsu Province is hosting more than 10 similar celebrations in Taizhou, Changzhou, Suzhou,
The Republic of China (ROC) is celebrating its 114th Double Ten National Day today, featuring military parades and a variety of performances and speeches in front of the Presidential Office in Taipei. The Taiwan Taiko Association opened the celebrations with a 100-drummer performance, including young percussionists. As per tradition, an air force Mirage 2000 fighter jet flew over the Presidential Office as a part of the performance. The Honor Guards of the ROC and its marching band also heralded in a military parade. Students from Taichung's Shin Min High School then followed with a colorful performance using floral imagery to represent Taiwan's alternate name
COGNITIVE WARFARE: Chinese fishing boats transmitting fake identification signals are meant to test Taiwan’s responses to different kinds of perceived incursions, a report said Chinese vessels are transmitting fake signals in Taiwan’s waters as a form of cognitive warfare, testing Taipei’s responses to various types of incursions, a report by the Institute for the Study of War said on Friday. Several Chinese fishing vessels transmitted fake automatic identification system (AIS) signals in Taiwan’s waters last month, with one mimicking a Russian warship and another impersonating a Chinese law enforcement vessel, the report said. Citing data from Starboard Maritime Intelligence, the report said that throughout August and last month, the Chinese fishing boat Minshiyu 06718 (閩獅漁06718) sailed through the Taiwan Strait while intermittently transmitting its own AIS
CHINESE INFILTRATION: Medical logistics is a lifeline during wartime and the reported CCP links of a major logistics company present a national security threat, an expert said The government would bolster its security check system to prevent China from infiltrating the nation’s medical cold chain, a national security official said yesterday. The official, who wished to stay anonymous, made the remarks after the Chinese-language magazine Mirror Media (鏡周刊) reported that Pharma Logistics (嘉里醫藥物流) is in charge of the medical logistics of about half of the nation’s major hospitals, including National Taiwan University Hospital and Taipei Veterans General Hospital. The company’s parent, Kerry TJ Logistics Co (嘉里大榮物流), is associated with the National Committee of the Chinese People’s Political Consultative Conference (CPPCC) and the Chinese People’s Liberation Army (PLA), the
