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.
SHIPS, TRAINS AND AUTOMOBILES: The ministry has announced changes to varied transportation industries taking effect soon, with a number of effects for passengers Beginning next month, the post office is canceling signature upon delivery and written inquiry services for international registered small packets in accordance with the new policy of the Universal Postal Union, the Ministry of Transportation and Communications said yesterday. The new policy does not apply to packets that are to be delivered to China, the ministry said. Senders of international registered small packets would receive a NT$10 rebate on postage if the packets are sent from Jan. 1 to March 31, it added. The ministry said that three other policies are also scheduled to take effect next month. International cruise ship operators
NUMBERS IMBALANCE: More than 4 million Taiwanese have visited China this year, while only about half a million Chinese have visited here Beijing has yet to respond to Taiwan’s requests for negotiation over matters related to the recovery of cross-strait tourism, the Tourism Administration said yesterday. Taiwan’s tourism authority issued the statement after Chinese-language daily the China Times reported yesterday that the government’s policy of banning group tours to China does not stop Taiwanese from visiting the country. As of October, more than 4.2 million had traveled to China this year, exceeding last year. Beijing estimated the number of Taiwanese tourists in China could reach 4.5 million this year. By contrast, only 500,000 Chinese tourists are expected in Taiwan, the report said. The report
HORROR STORIES: One victim recounted not realizing they had been stabbed and seeing people bleeding, while another recalled breaking down in tears after fleeing A man on Friday died after he tried to fight the knife-wielding suspect who went on a stabbing spree near two of Taipei’s busiest metro stations, Taipei Mayor Chiang Wan-an (蔣萬安) said. The 57-year-old man, identified by his family name, Yu (余), encountered the suspect at Exit M7 of Taipei Main Station and immediately tried to stop him, but was fatally wounded and later died, Chiang said, calling the incident “heartbreaking.” Yu’s family would receive at least NT$5 million (US$158,584) in compensation through the Taipei Rapid Transit Corp’s (TRTC) insurance coverage, he said after convening an emergency security response meeting yesterday morning.

The Forestry and Nature Conservation Agency yesterday launched a gift box to market honey “certified by a Formosan black bear” in appreciation of a beekeeper’s amicable interaction with a honey-thieving bear. Beekeeper Chih Ming-chen (池明鎮) in January inspected his bee farm in Hualien County’s Jhuosi Township (卓溪) and found that more than 20 beehives had been destroyed and many hives were eaten, with bear droppings and paw prints near the destroyed hives, the agency said. Chih returned to the farm to move the remaining beehives away that evening when he encountered a Formosan black bear only 20m away, the agency said. The bear
