The first model of the Formosat-8 satellite project, the FS-8A, is set to ship to the US next month and launch into orbit in October, the Taiwan Space Agency (TASA) said yesterday.
The FS-8A, Taiwan’s first remote-sensing satellite, completed all its functions tests, and could now be certified and prepared for launch, the agency said.
After passing a pre-shipment review and calibration early next month, it would be shipped to the US’ Vandenberg Space Force Base to be launched on a SpaceX Falcon 9 Transporter 15 ridesharing mission in October.

The Formosat-8 program is a priority mission in the third phase of the national space technology program. It involves launching eight remote-sensing satellites, with six of them having the ability to capture high-resolution images of objects 1m above ground from an altitude of 561km. The other two satellites allow it to capture images less than 1m above ground.
One satellite is to be launched annually until 2031, and deployed to orbit around the Earth at a 561km altitude.
TASA Director-General Wu Jong-shinn (吳宗信) said that the project has faced multiple delays, but those issues were overcome through the patience and hard work of the development team.
Compared with Formosat-5, Formosat-8 can provide resolutions of less than 1m, Wu added.
Once in orbit, the satellites would pass over Taiwan multiple times per day, significantly enhancing the nation’s national security and disaster response needs, he said.
Formosat-8 project manager Cynthia Liu (劉小菁) said that the satellite has gone through rigorous testing to ensure that it could withstand the launch and the harsh conditions in space.
Given that satellites cannot be repaired once they are in space, it is essential to find and fix all issues while still on the ground, Liu added.
For example, the team found that the satellite had an issue sending commands to its propulsion system, she said, adding that it was resolved in three days.
Ye Chia-ching (葉嘉靖), who is in charge of testing the FS-8A, said that assembly and testing took more than a year, although the team completed its most difficult thermal vacuum test in only half the time expected.
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.

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
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
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.
