Japan's first lunar orbiter successfully blasted into space yesterday on the most extensive mission to investigate the moon since the US Apollo program began nearly four decades ago, officials said.
A domestically developed rocket launched with no glitches from Tanegashima, the remote island where the agency's space center is located, at 10:31am carrying the country's hopes of restoring pride in its troubled space program.
The orbiter separated from the H-2A rocket about 45 minutes after it took off from the Space Center, the space agency said.

"The launch was a success," declared Kaoru Mamiya, vice president of the Japan Aerospace Exploration Agency (JAXA) in Tokyo.
"The probe detached from the rocket as expected 45 minutes after lift-off and all the subsequent phases were carried out correctly," said Yoshisada Takizawa, the head of the project.
The lunar orbiter, aiming to collect data for research of the moon's origin and evolution, will travel around the Earth before moving into an orbit of the moon early next month, officials said.
The agency says the one-year lunar mission, which is several years behind schedule because of technical mishaps, is the most extensive since the US Apollo program began in the 1960s, putting the first astronaut on the moon.
The explorer was named Kaguya after a beautiful princess who charms many men before ascending to her home, the moon, in a popular Japanese folk tale.
The ?55 billion (US$478 million) probe will consist of a main unit, which will orbit 100km above the moon, and two small satellites.
It will gather data on the distribution of chemical elements and minerals as well as on topographical and surface structures.
The mission aims to study the gravity field and environment of the moon while searching for hydrogen, which is required for water.
"Japan aims to build a station on the surface of the moon in 2025 and so we need to understand the moon. We need to develop the fundamental technology," said Satoki Kurokawa, another spokesman for the agency.
Japan has been expanding its space operations and has set a goal of sending an astronaut to the moon by 2020. It faced an embarrassing failure in November 2003, when it had to destroy a rocket carrying a spy satellite 10 minutes after lift-off because a booster failed to separate.
The setback came just a month after China became the third country to carry out a manned space mission. China is pressing ahead with a program that includes space walks and dockings.
With the lunar orbiter, Japan hopes to keep one step ahead of China and other regional rivals like India, which are also expected to launch similar probes soon.
"This program is very important for science throughout the world. If it is completed successfully, it will push back the frontiers of humanity beyond Earth and heighten Japan's technological status," said Hajime Inoue, director of space research at JAXA.
China is expected to launch its Chang'e 1 probe as early as this month, to be followed by India's Chandrayaan 1 later this year.

SECURITY: Taipei presses the US for arms supplies, saying the arms sales are not only a reflection of the US security commitment to Taiwan but also serve as a mutual deterrent against regional threats Taiwan is committed to preserving the cross-strait “status quo” and contributing to regional peace and stability, the Presidential Office said yesterday. “It is an undeniable fact that the Republic of China is a sovereign and independent democratic nation,” Presidential Office spokeswoman Karen Kuo (郭雅慧) reiterated, adding that Beijing has no right to claim sovereignty over Taiwan. The statements came after US President Donald Trump warned against Taiwanese independence. Trump wrapped up a state visit to Beijing on Friday, during which Chinese President Xi Jinping (習近平) had pressed him not to support Taiwan. Taiwan depends heavily on US security backing to deter China from carrying
The subsidiary of Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) in Kumamoto, Japan, turned a profit in the first quarter of this year, marking the first time the first fab of the unit has become profitable since mass production started at the end of 2024. According to the contract chipmaker’s financial statement released on Friday, Japan Advanced Semiconductor Manufacturing Inc (JASM), a joint venture running the fab in Kumamoto, posted NT$951 million (US$30.19 million) in profit in the January-to-March period, compared with a loss of NT$1.39 billion in the previous quarter, and a loss of NT$3.25 billion in the first quarter of
RESOLUTE BACKING: Two Republican senators are planning to introduce legislation that would impose immediate sanctions on China if it attempts to invade Taiwan US House of Representatives Speaker Mike Johnson on Sunday reaffirmed US congressional support for Taiwan, saying the US and “all freedom-loving people” have a stake in preventing China from seizing Taiwan by force. Johnson made the remarks in an interview with Fox News Sunday on US President Donald Trump’s summit with Chinese President Xi Jinping (習近平) last week. In an interview that aired on Friday on Fox News, just as Trump wrapped up a high-stakes visit to China, he said he has yet to green-light a new US$14 billion arms package to Taiwan and that it “depends on China.” “It’s a very good
US President Donald Trump yesterday said he would speak to President William Lai (賴清德) as his administration considers whether to move ahead with a US$14 billion weapons sale to Taiwan — a potential arms deal that has drawn criticism from China. “Well, I’ll speak to him. I speak to everybody,” Trump told reporters yesterday when asked if he had any plans to call his counterpart, although he did not offer a time frame for when such a conversation could take place. Trump previously said he would speak to the person “that’s running Taiwan,” without specifying who he meant. “We have that situation very
