TOKYO — Japan’s flagship H3 rocket reached orbit and released two small observation satellites in a key second test following a failed debut launch last year, buoying hope for the country in the global space race.
The H3 rocket blasted off from the Tanegashima Space Center on time Saturday morning, two days after its originally scheduled liftoff was delayed by bad weather.
The rocket successfully reached orbit at an altitude of about 670 kilometers (about 420 miles) and released two satellites, said the Japan Aerospace Exploration Agency, or JAXA.
“We feel so relieved to be able to announce the good results,” JAXA President Hiroshi Yamakawa told a news conference.
The H3’s main missions are to secure independent access to space and be competitive as international demand for satellite launches grows. “We made a big first step today toward achieving that goal,” Yamakawa said.
The launch is a boost for Japan’s space program following a recent streak of successes, including a historic precision touchdown on the moon of an unmanned spacecraft last month.
The liftoff was closely watched as a test for Japan’s space development after H3, in its debut flight last March, failed to ignite the second-stage engine. JAXA and its main contractor, Mitsubishi Heavy Industries, have been developing H3 as a successor to its current mainstay, H-2A, which is set to retire after two more flights.
JAXA H3 project manager Masashi Okada called the result “perfect,” saying H3 cleared all missions set for Saturday’s flight. “After a long wait, the newborn H3 finally had its first cry.”
At 57 meters (187 feet) long, the H3 is designed to carry larger payloads than H-2A at much lower costs of about 50 billion yen ($330 million).
