Formosat-5, the nation’s first domestically developed remote-sensing satellite, has taken more than 60,000 images since it was launched five years ago, the National Science and Technology Council said on the anniversary of its launch on Thursday.
The satellite was launched on Aug. 25, 2017, from Vandenberg Air Force Base in California by SpaceX’s Falcon 9 rocket, and began commercial operations on Sept. 21, 2018.
Since then, it has taken more than 60,000 images with a success rate of 94.87 percent, council data showed.

Formosat-5 not only established Taiwan as a capable developer of satellites and optical parts, but also helps with disaster response around the world, council Minister Wu Tsung-tsong (吳政忠) said.
In the past five years, it has provided images of areas affected by 19 domestic and 101 international disasters, council data showed.
These include major events such as the July 2019 Ridgecrest earthquakes in southern California, flooding in Kaohsiung on Aug. 6 last year and the Hunga Tonga-Hunga Ha’apai volcanic eruption in the South Pacific in January, the council said.
Through the images, countries could grasp a better understanding of the respective situation on the ground, it said.
Large-scale wind events, weather and other factors can affect the operation of reconnaissance aircraft, but satellite images can be taken immediately, the National Space Organization (NSPO) said.
The satellite also helps governments, industry and academics with ecological monitoring, Wu said.
For instance, Formosat-5 has helped countries in Central America fight Panama disease, which poses a serious threat to banana crops, the council said.
As the banana industry is crucial for diplomatic allies Guatemala, Honduras and Belize, they sought assistance from Taiwan to fight the fungus-caused disease, it said.
Researchers developed a program that can automatically identify affected areas through regular images taken by Formosat-5, enabling farmers to quickly remove threatened plants and stymie the spread, it added.
Formosat-5 set a milestone for Taiwanese space technology, the council said.
Third-party manufacturers involved in the satellite’s production have achieved the highest level of NASA’s nine-tiered technology readiness system, granting the industry a firm foothold in international markets, it added.
Formosat-5 is still in good condition, even though it has reached the end of its expected lifespan, the NSPO said.
For now, it is to remain in operation, with plans to experiment with other functions to gather data for future satellite design and maintenance, it added.
A preclearance service to facilitate entry for people traveling to select airports in Japan would be available from Thursday next week to Feb. 25 at Taiwan Taoyuan International Airport, Taoyuan International Airport Corp (TIAC) said on Tuesday. The service was first made available to Taiwanese travelers throughout the winter vacation of 2024 and during the Lunar New Year holiday. In addition to flights to the Japanese cities of Hakodate, Asahikawa, Akita, Sendai, Niigata, Okayama, Takamatsu, Kumamoto and Kagoshima, the service would be available to travelers to Kobe and Oita. The service can be accessed by passengers of 15 flight routes operated by
Chinese spouse and influencer Guan Guan’s (關關) residency permit has been revoked for repeatedly posting pro-China videos that threaten national security, the National Immigration Agency confirmed today. Guan Guan has said many controversial statements in her videos posted to Douyin (抖音), including “the red flag will soon be painted all over Taiwan” and “Taiwan is an inseparable part of China,” and expressing hope for expedited reunification. The agency last year received multiple reports alleging that Guan Guan had advocated for armed reunification. After verifying the reports, the agency last month issued a notice requiring her to appear and explain her actions. Guan
GIVE AND TAKE: Blood demand continues to rise each year, while fewer young donors are available due to the nation’s falling birthrate, a doctor said Blood donors can redeem points earned from donations to obtain limited edition Formosan black bear travel mugs, the Kaohsiung Blood Center said yesterday, as it announced a goal of stocking 20,000 units of blood prior to the Lunar New Year. The last month of the lunar year is National Blood Donation Month, when local centers seek to stockpile blood for use during the Lunar New Year holiday. The blood demand in southern Taiwan — including Tainan and Kaohsiung, as well as Chiayi, Pingtung, Penghu and Taitung counties — is about 2,000 units per day, the center said. The donation campaign aims to boost
The Central Weather Administration (CWA) said a magnitude 4.9 earthquake that struck off the coast of eastern Taiwan yesterday was an independent event and part of a stress-adjustment process. The earthquake occurred at 4:47pm, with its epicenter at sea about 45.4km south of Yilan County Hall at a depth of 5.9km, the CWA said. The quake's intensity, which gauges the actual effects of a temblor, was highest in several townships in Yilan and neighboring Hualien County, where it measured 4 on Taiwan's seven-tier intensity scale, the CWA said. Lin Po-yu (林柏佑), a division chief at the CWA's Seismological Center, told a news conference
