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.
Chinese Nationalist Party (KMT) Chairman Eric Chu (朱立倫), spokeswoman Yang Chih-yu (楊智伃) and Legislator Hsieh Lung-chieh (謝龍介) would be summoned by police for questioning for leading an illegal assembly on Thursday evening last week, Minister of the Interior Liu Shyh-fang (劉世芳) said today. The three KMT officials led an assembly outside the Taipei City Prosecutors’ Office, a restricted area where public assembly is not allowed, protesting the questioning of several KMT staff and searches of KMT headquarters and offices in a recall petition forgery case. Chu, Yang and Hsieh are all suspected of contravening the Assembly and Parade Act (集會遊行法) by holding
PRAISE: Japanese visitor Takashi Kubota said the Taiwanese temple architecture images showcased in the AI Art Gallery were the most impressive displays he saw Taiwan does not have an official pavilion at the World Expo in Osaka, Japan, because of its diplomatic predicament, but the government-backed Tech World pavilion is drawing interest with its unique recreations of works by Taiwanese artists. The pavilion features an artificial intelligence (AI)-based art gallery showcasing works of famous Taiwanese artists from the Japanese colonial period using innovative technologies. Among its main simulated displays are Eastern gouache paintings by Chen Chin (陳進), Lin Yu-shan (林玉山) and Kuo Hsueh-hu (郭雪湖), who were the three young Taiwanese painters selected for the East Asian Painting exhibition in 1927. Gouache is a water-based
Taiwan would welcome the return of Honduras as a diplomatic ally if its next president decides to make such a move, Minister of Foreign Affairs Lin Chia-lung (林佳龍) said yesterday. “Of course, we would welcome Honduras if they want to restore diplomatic ties with Taiwan after their elections,” Lin said at a meeting of the legislature’s Foreign Affairs and National Defense Committee, when asked to comment on statements made by two of the three Honduran presidential candidates during the presidential campaign in the Central American country. Taiwan is paying close attention to the region as a whole in the wake of a
OFF-TARGET: More than 30,000 participants were expected to take part in the Games next month, but only 6,550 foreign and 19,400 Taiwanese athletes have registered Taipei city councilors yesterday blasted the organizers of next month’s World Masters Games over sudden timetable and venue changes, which they said have caused thousands of participants to back out of the international sporting event, among other organizational issues. They also cited visa delays and political interference by China as reasons many foreign athletes are requesting refunds for the event, to be held from May 17 to 30. Jointly organized by the Taipei and New Taipei City governments, the games have been rocked by numerous controversies since preparations began in 2020. Taipei City Councilor Lin Yen-feng (林延鳳) said yesterday that new measures by
