Taiwan's National Central University (NCU) announced the successful launch of the country's first lunar mission yesterday, as its Deep Space Radiation Probe (DSRP) was carried into space and is expected to land on the moon in four months.
The DSRP is aboard the lunar lander HAKUTO-R Mission 2 developed by ispace, a Japanese lunar exploration company, and launched from Florida at 2:11pm yesterday via the US space technology company SpaceX's Falcon 9 rocket, NCU said in a statement.
One hour and 32 minutes after takeoff, the lunar lander separated from the launch vehicle.

The DSRP is scheduled to begin operation 36 hours after the launch and NCU's team is set to receive and analyze the data it collects, NCU added.
Featuring the emblem of NCU and the words "Made in Taiwan" on its lower-left corner, the DSRP was Taiwan's first domestically-built scientific payload for a lunar mission and the first to leave low Earth orbit (LEO), which extends to an altitude of 2,000 km, NCU noted.
The DSRP, independently developed by faculty and students of NCU's Department of Space Science and Engineering, weighs only 399 grams but is capable of withstanding stress 33 times its weight and operating under radiation doses exceeding 10 kRads, said Loren Chang (張起維), chair of the department that is leading the lunar mission.
"This project kicked off in 2022 and we went through five different revisions before we got to the version that we felt comfortable watching," Chang told CNA in a phone interview.
The rugged design of the DSRP was necessary as the probe would be traveling to deep space — defined by Chang's team as regions outside of LEO — where the earth's magnetic shield is much weaker, exposing the probe to harsher radiation conditions that could affect technological products, he said.
Additionally, landing on the moon may involve "strong shocks," which would require a robust structure, Chang added.
The mission is aimed at measuring the expected radiation dose between the earth and the moon, as well as on the lunar surface, and understanding the radiation-caused anomalies of electronics commonly used on board a spacecraft, he said.
"By understanding the radiation dose, we can better prepare for missions to the moon and to deep space with human beings," he added.
Asked how he and his team felt after the successful launch, Chang said that they were all "very relieved" as the launch occurred with no delays or cancellations, which are common.
There were several critical stages during a launch, including reaching maximum dynamic pressure and the separation of the spacecraft from the launch vehicle, he said.
"These all went off without a hitch, so we're very, very relieved," he said.
After the successful launch, the lunar lander, carrying the DSRP, is to take a low-energy trajectory to gradually approach the moon, requiring around four months to cover the approximately 400,000km between the earth and the moon, he said.
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
