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.
Twenty-four Republican members of the US House of Representatives yesterday introduced a concurrent resolution calling on the US government to abolish the “one China” policy and restore formal diplomatic relations with Taiwan. Led by US representatives Tom Tiffany and Scott Perry, the resolution calls for not only re-establishing formal relations, but also urges the US Trade Representative to negotiate a free-trade agreement (FTA) with Taiwan and for US officials to advocate for Taiwan’s full membership in the UN and other international organizations. In a news release announcing the resolution, Tiffany, who represents a Wisconsin district, called the “one China” policy “outdated, counterproductive
Actress Barbie Hsu (徐熙媛) has “returned home” to Taiwan, and there are no plans to hold a funeral for the TV star who died in Japan from influenza- induced pneumonia, her family said in a statement Wednesday night. The statement was released after local media outlets reported that Barbie Hsu’s ashes were brought back Taiwan on board a private jet, which arrived at Taipei Songshan Airport around 3 p.m. on Wednesday. To the reporters waiting at the airport, the statement issued by the family read “[we] appreciate friends working in the media for waiting in the cold weather.” “She has safely returned home.
ON PAROLE: The 73-year-old suspect has a criminal record of rape committed when he was serving in the military, as well as robbery and theft, police said The Kaohsiung District Court yesterday approved the detention of a 73-year-old man for allegedly murdering three women. The suspect, surnamed Chang (張), was arrested on Wednesday evening in connection with the death of a 71-year-old woman surnamed Chao (趙). The Kaohsiung City Police Department yesterday also unveiled the identities of two other possible victims in the serial killing case, a 75-year-old woman surnamed Huang (黃), the suspect’s sister-in-law, and a 75-year-old woman surnamed Chang (張), who is not related to the suspect.

TRUMP ERA: The change has sparked speculation on whether it was related to the new US president’s plan to dismiss more than 1,000 Joe Biden-era appointees The US government has declined to comment on a post that indicated the departure of Laura Rosenberger as chair of the American Institute in Taiwan (AIT). Neither the US Department of State nor the AIT has responded to the Central News Agency’s questions on the matter, after Rosenberger was listed as a former chair on the AIT’s official Web site, with her tenure marked as 2023 to this year. US officials have said previously that they usually do not comment on personnel changes within the government. Rosenberger was appointed head of the AIT in 2023, during the administration of former US president Joe
