The National Space Organization (NSPO) yesterday signed memorandums of agreement with Linkou Chang Gung Memorial Hospital and Chang Gung University to boost the nation’s capabilities in radiation testing of satellite components and space industry development.
The documents were signed by NSPO Director-General Lin Chun-liang (林俊良), the hospital’s Proton and Radiation Therapy Center convener Hung Ji-hong (洪志宏) and the university’s Institute for Radiological Research dean Tung Chuan-jong (董傳中).
Electronic components used in satellites have to be resistant to space radiation, which can disrupt electronic signals or cause systems to work incorrectly or even break down, the NSPO said.

The hospital in November 2015 set a milestone in cancer treatment by putting four proton radiotherapy devices — the world’s most advanced — into clinical service, the organization said.
The hospital also set up a particle physics and beam delivery core laboratory for research purposes, such as electronic component testing, the NSPO said.
Radiation testing of satellite components in simulated space conditions include total radiation dose testing and proton radiation testing, NSPO Deputy Director-General Yu Shiann-jen (余憲政) said.
While total dose testing can be performed at National Tsing Hua University’s Nuclear Science and Technology Development Center, only the Atomic Energy Council’s Institute of Nuclear Energy Research can conduct proton radiation testing, but its facilities cannot meet the requirement of testing up to 150 mega-electron-volts (MeV), he said.
Previously, the NSPO had to ask foreign institutions, such as Texas A&M University or the University of California, Berkeley, to conduct tests, which took months and involved costs up to hundreds of thousands or even millions of New Taiwan dollars, he said.
The hospital’s facilities allow testing up to 150MeV, which would greatly improve the testing efficiency of locally developed components, Yu said.
The NSPO would serve as a consultant for Chang Gung institutions in matters related to space technology, while the institutions would charge component developers for testing, he said.
In related news, the NSPO is to exhibit key component models of remote sensing satellite Formosat-5 and the Triton microsatellite, part of the Formosat-7 array, in a technology show in Indonesia in September organized by the Taiwan External Trade Development Council.
Formosat-5, the nation’s first domestically developed satellite, was launched on Aug. 25, 2017, form California, the Triton weather satellite, of which most key components were developed by Taiwanese scientists, is scheduled to be launched in 2021.
Indonesia is a major player in space technology in Southeast Asia after India, and it also aspires for autonomous satellite development, Yu said, adding that the NSPO looks forward to more collaboration with the country.
SPACE VETERAN: Kjell N. Lindgren, who helps lead NASA’s human spaceflight missions, has been on two expeditions on the ISS and has spent 311 days in space Taiwan-born US astronaut Kjell N. Lindgren is to visit Taiwan to promote technological partnerships through one of the programs organized by the US for its 250th national anniversary. Lindgren would be in Taiwan from Tuesday to Saturday next week as part of the US Bureau of Educational and Cultural Affairs’ US Speaker Program, organized to celebrate the 250th anniversary of the signing of the Declaration of Independence, the American Institute in Taiwan (AIT) said in a statement yesterday. Lindgren plans to engage with key leaders across the nation “to advance cutting-edge technological partnerships and inspire the next generation of scientists and engineers,”
UNREASONABLE SURVEILLANCE: A camera targeted on an road by a neighbor captured a man’s habitual unsignaled turn into home, netting him dozens of tickets The Taichung High Administrative Court has canceled all 45 tickets given to a man for failing to use a turn signal while driving, as it considered long-term surveillance of his privacy more problematic than the traffic violations. The man, surnamed Tseng (曾), lives in Changhua County and was reported 45 times within a month for failing to signal while driving when he turned into the alley where his residence is. The reports were filed by his neighbor, who set up security cameras that constantly monitored not only the alley but also the door and yard of Tseng’s house. The surveillance occurred from July
A Japan Self-Defense Forces vessel entered the Taiwan Strait yesterday, Japanese media reported. After passing through the Taiwan Strait, the Ikazuchi was to proceed to the South China Sea to take part in a joint military exercise with the US and the Philippines, the reports said. Japan Self-Defense Force vessels were first reported to have passed through the strait in September, 2024, with two further transits taking place in February and June last year, the Asahi Shimbun reported. Yesterday’s transit also marked the first time since Japanese Prime Minister Sanae Takaichi took office that a Japanese warship has been sent through the Taiwan
‘SAME OLD TRICK’: Even if Beijing resumes individual travel to Taiwan, it would only benefit Chinese tourism companies, the Economic Democracy Union convener said China’s 10 new “incentives” are “sugar-coated poison,” an official said yesterday, adding that Taiwanese businesses see them clearly for what they are, but that Beijing would inevitably find some local collaborators to try to drums up support. The official, speaking on condition of anonymity, made the remark ahead of a news conference the General Chamber of Commerce is to hold today. The event, titled “Industry Perspectives on China’s Recent Pro-Taiwan Policies,” is expected to include representatives from industry associations — such as those in travel, hotels, food and agriculture — to request the government cooperate with China’s new measures, people familiar with
