The nation’s first domestically developed satellite, Formosat-5, has taken images at the resolution it was designed to deliver, but only “when weather conditions are good,” Ministry of Science and Technology (MOST) officials said yesterday, adding it has completed its mission of capturing satellite images of Taiwan.
The satellite was launched from Vandenberg Air Force Base in California on Aug. 25 last year, but the first images it transmitted back in September last year were fuzzy and marred by light spots.
Since then, the National Space Organization (NSPO) has been working to improve its image quality using image processing software and by adjusting the satellite’s altitude, angle and the temperature of its imaging device.

At a news conference in Taipei yesterday, project director Chang Ho-pen (張和本) said the satellite has achieved the resolution it was designed to produce — 2m for black-and-white images and 4m for color images — when the weather permits.
“For example, the satellite images taken from above China and from above California can be very different when the former has serious air pollution,” Chang said.
Yet, the NSPO has not quantified what weather conditions would allow the satellite to transmit images at its default resolution, he added.

The satellite’s images have already proven sufficient in supporting the nation’s disaster prevention missions, and would be available on the organization’s Web site from September, he said, adding that the US, Japan, Russia and Australia have expressed an interest in purchasing the images.
Asked if Formosat-5’s performance has achieved the ministry’s objectives, Chang said “yes,” while Minister of Science and Technology Chen Liang-gee (陳良基) gave a more reserved response.
The imaging capabilities of Formosate-5 have surpassed those of Formosat-2, which has a 2m resolution for monochromatic images and 8m for colored ones, Chen said.
However, when compared with the US Army’s stricter requirements, it only achieves a 3m resolution for black-and-white images and 5m for colored ones, he said.
As the NSPO is planning to launch one satellite per year in the following 10 years, it will pay more attention to the mechanical adjustment and microwave sensing capabilities of satellites, Chen said.
Meanwhile, Formosat-5, which passes over the same spot on Earth every two days, has finished taking remote images of Taiwan during its orbits between September and December last year, he said.
The ministry presented a complete satellite image of Taiwan to President Tsai Ing-wen (蔡英文) yesterday, with Tsai promising to support its space programs, Chen added.
Police have detained a Taoyuan couple suspected of over the past two months colluding with human trafficking rings and employment scammers in Southeast Asia to send nearly 100 Taiwanese jobseekers to Cambodia. At a media briefing in Taipei yesterday, the Criminal Investigation Bureau presented items seized from the couple, including alleged victims’ passports, forged COVID-19 vaccination records, mobile phones, bank documents, checks and cash. The man, surnamed Tsai (蔡), and his girlfriend, surnamed Tsan (詹), were taken into custody last month, after police at Taiwan Taoyuan International Airport stopped four jobseekers from boarding a flight to Phnom Penh, said Dustin Lee (李泱輯),
BILINGUAL PLAN: The 17 educators were recruited under a program that seeks to empower Taiwanese, the envoy to the Philippines said The Taipei Economic and Cultural Office in the Philippines on Thursday hosted a send-off event for the first group of English-language teachers from the country who were recruited for a Ministry of Education-initiated program to advance bilingual education in Taiwan. The 14 teachers and three teaching assistants are part of the Taiwan Foreign English Teacher Program, which aims to help find English-language instructors for Taiwan’s public elementary and junior-high schools, the office said. Seventy-seven teachers and 11 teaching assistants from the Philippines have been hired to teach in Taiwan in the coming school year, office data showed. Among the first group is 57-year-old
TRICKED INTO MOVING: Local governments in China do not offer any help, and Taiwanese there must compete with Chinese in an unfamiliar setting, a researcher said Beijing’s incentives for Taiwanese businesspeople to invest in China are only intended to lure them across the Taiwan Strait, after which they receive no real support, an expert said on Sunday. Over the past few years, Beijing has been offering a number of incentives that “benefit Taiwanese in name, while benefiting China in reality,” a cross-strait affairs expert said on condition of anonymity. Strategies such as the “31 incentives” are intended to lure Taiwanese talent, capital and technology to help address China’s economic issues while also furthering its “united front” efforts, they said. Local governments in China do not offer much practical
‘ORDINARY PEOPLE’: A man watching Taiwanese military drills said that there would be nothing anyone could do if the situation escalates in the Taiwan Strait Many people in Taiwan look upon China’s military exercises over the past week with calm resignation, doubting that war is imminent and if anything, feeling pride in their nation’s determination to defend itself. After a visit to Taiwan last week by US House of Representatives Speaker Nancy Pelosi, China has sent ships and aircraft across an unofficial buffer between Taiwan and China’s coast and missiles over Taipei and into waters surrounding the nation since Thursday last week. However, Rosa Chang, proudly watching her son take part in Taiwanese military exercises that included dozens of howitzers firing shells into the Taiwan Strait off
