Researchers at National Cheng Kung University (NCKU) yesterday conducted a successful test flight in Pingtung County of a two-stage rocket using a hybrid propulsion system.
The 6.2m, 260kg rocket was launched at a National Space Organization (NSPO) test site in Mudan Township (牡丹) at 6:47am, the National Science and Technology Council said in a statement.
The launch tested the rocket’s hybrid propulsion system, which uses a mix of liquid and solid-state propellants, the council said.

Under the initial flight plan, a 1,500kg force of thrust was achieved in the liftoff phase, which propelled the rocket into the sky for 13 seconds before a 300kg-force thrust booster kicked in during the separation phase.
However, the propulsion time and the accomplished altitude are to be determined after a review of the results, the council said.
The test represented the first launch of a hybrid rocket by a Taiwanese academic institution that utilized a two-stage thrust of 1,500kg force and 300kg force, it said.
It is hoped that the Tainan-based university’s hybrid rocket can be modified to carry payloads for scientific research in the near future, the NSPO said.
NCKU Department of Aeronautics and Astronautics chair professor Chao Yi-chin (趙怡欽) said the propulsion system was based on the university’s 1,500kg-force thrust technology developed in 2019, but had been further refined after three years of research.
The key components and instruments used to make the rocket, regardless of design, technology and manufacturing, were sourced entirely in Taiwan, Chao said.
The rocket also features a built-in Compact Scintillator Array Detector (ComSAD) developed by NCKU Department of Physics associate professor Yang Yi (楊毅), he said.
ComSAD is a high-energy cosmic ray detector used in sounding rockets and cube satellites to detect the energy and direction of cosmic rays.
The sounding rocket launch yesterday was also used to test the basic functions of the ComSAD for future missions, the council said.
The Taiwanese passport ranked 33rd in a global listing of passports by convenience this month, rising three places from last month’s ranking, but matching its position in January last year. The Henley Passport Index, an international ranking of passports by the number of designations its holder can travel to without a visa, showed that the Taiwan passport enables holders to travel to 139 countries and territories without a visa. Singapore’s passport was ranked the most powerful with visa-free access to 192 destinations out of 227, according to the index published on Tuesday by UK-based migration investment consultancy firm Henley and Partners. Japan’s and
NATIONAL SECURITY THREAT: An official said that Guan Guan’s comments had gone beyond the threshold of free speech, as she advocated for the destruction of the ROC China-born media influencer Guan Guan’s (關關) residency permit has been revoked for repeatedly posting pro-China content that threatens national security, the National Immigration Agency said yesterday. Guan Guan has said many controversial things in her videos posted to Douyin (抖音), including “the red flag will soon be painted all over Taiwan” and “Taiwan is an inseparable part of China,” while expressing hope for expedited “reunification.” The agency received multiple reports alleging that Guan Guan had advocated for armed reunification last year. After investigating, the agency last month issued a notice requiring her to appear and account for her actions. Guan Guan appeared as required,
Japan and the Philippines yesterday signed a defense pact that would allow the tax-free provision of ammunition, fuel, food and other necessities when their forces stage joint training to boost deterrence against China’s growing aggression in the region and to bolster their preparation for natural disasters. Japan has faced increasing political, trade and security tensions with China, which was angered by Japanese Prime Minister Sanae Takaichi’s remark that a Chinese attack on Taiwan would be a survival-threatening situation for Japan, triggering a military response. Japan and the Philippines have also had separate territorial conflicts with Beijing in the East and South China
A strong cold air mass is expected to arrive tonight, bringing a change in weather and a drop in temperature, the Central Weather Administration (CWA) said. The coldest time would be early on Thursday morning, with temperatures in some areas dipping as low as 8°C, it said. Daytime highs yesterday were 22°C to 24°C in northern and eastern Taiwan, and about 25°C to 28°C in the central and southern regions, it said. However, nighttime lows would dip to about 15°C to 16°C in central and northern Taiwan as well as the northeast, and 17°C to 19°C elsewhere, it said. Tropical Storm Nokaen, currently
