Japan launches a climate change monitoring satellite on mainstay H2A rocket's last flight

TOKYO (AP) — Japan on Sunday successfully launched a climate change monitoring satellite on its mainstay H-2A rocket, which made its final flight before it is replaced by a new flagship model designed to be more cost competitive in the global space market.

The H-2A rocket lifted off from the Tanegashima Space Center in southwestern Japan, carrying the GOSAT-GW satellite as part of Tokyo’s effort to mitigate climate change. The satellite was safely separated from the rocket and released into a planned orbit about 16 minutes later.

Scientists and space officials at the control room exchanged hugs and handshakes to celebrate the successful launch, which was delayed by several days due to a malfunctioning of the rocket's electrical systems.

Keiji Suzuki, a Mitsubishi Heavy Industries official in charge of rocket launch operations, said he was more nervous than ever for the final mission of the rocket, which has been his career work. “I've spent my entire life at work not to drop H-2A rocket ... All I can say is I'm so relieved."

Sunday's launch marked the 50th and final flight for the H-2A, which has served as Japan’s mainstay rocket to carry satellites and probes into space with a near-perfect record since its 2001 debut. After its retirement, it will be fully replaced by the H3, which is already in operation, as Japan's new main flagship.

“It is a deeply emotional moment for all of us at JAXA as a developer,” Hiroshi Yamakawa, president of the Japan Aerospace Exploration Agency, told a news conference.

The GOSAT-GW, or Global Observing SATellite for Greenhouse gases and Water cycle, is a third series in the mission to monitor carbon, methane and other greenhouse gasses in the atmosphere. Within one year, it will start distributing data such as sea surface temperature and precipitation with much higher resolution to users around the world, including the U.S. National Oceanic and Atmospheric Administration, officials said.

The liquid-fuel H-2A rocket with two solid-fuel sub-rockets developed by Japan Aerospace Exploration Agency has so far had 49 flights with a 98% success record, with only one failure in 2003. Mitsubishi Heavy has provided its launch operation since 2007.

H-2A successfully carried into space many satellites and probes, including Japan’s moon lander SLIM last year, and a popular Hayabusa2 spacecraft in 2014 to reach a distant asteroid, contributing to the country’s space programs.

The completion of H-2A lets him put more resources into further development of the H3, Suzuki said.

Japan sees a stable, commercially competitive space transport capability as key to its space program and national security, and has been developing two new flagship rockets as successors of the H-2A series — the larger H3 with Mitsubishi, and a much smaller Epsilon system with the aerospace unit of the heavy machinery maker IHI. It hopes to cater to diverse customer needs and improve its position in the growing satellite launch market.

The H3, is designed to carry larger payloads than the H-2A at about half its launch cost to be globally competitive, though officials say more cost reduction efforts are needed to achieve better price competitiveness in the global market.

The H3 has made four consecutive successful flights after a failed debut attempt in 2023, when the rocket had to be destroyed with its payload.

ALEPPO, Syria (AP) — First responders on Sunday entered a contested neighborhood in Syria’ s northern city of Aleppo after days of deadly clashes between government forces and Kurdish-led forces. Syrian state media said the military was deployed in large numbers.

The clashes broke out Tuesday in the predominantly Kurdish neighborhoods of Sheikh Maqsoud, Achrafieh and Bani Zaid after the government and the Syrian Democratic Forces, the main Kurdish-led force in the country, failed to make progress on how to merge the SDF into the national army. Security forces captured Achrafieh and Bani Zaid.

The fighting between the two sides was the most intense since the fall of then-President Bashar Assad to insurgents in December 2024. At least 23 people were killed in five days of clashes and more than 140,000 were displaced amid shelling and drone strikes.

The U.S.-backed SDF, which have played a key role in combating the Islamic State group in large swaths of eastern Syria, are the largest force yet to be absorbed into Syria's national army. Some of the factions that make up the army, however, were previously Turkish-backed insurgent groups that have a long history of clashing with Kurdish forces.

The Kurdish fighters have now evacuated from the Sheikh Maqsoud neighborhood to northeastern Syria, which is under the control of the SDF. However, they said in a statement they will continue to fight now that the wounded and civilians have been evacuated, in what they called a “partial ceasefire.”

The neighborhood appeared calm Sunday. The United Nations said it was trying to dispatch more convoys to the neighborhoods with food, fuel, blankets and other urgent supplies.

Government security forces brought journalists to tour the devastated area, showing them the damaged Khalid al-Fajer Hospital and a military position belonging to the SDF’s security forces that government forces had targeted.

The SDF statement accused the government of targeting the hospital “dozens of times” before patients were evacuated. Damascus accused the Kurdish-led group of using the hospital and other civilian facilities as military positions.

On one street, Syrian Red Crescent first responders spoke to a resident surrounded by charred cars and badly damaged residential buildings.

Some residents told The Associated Press that SDF forces did not allow their cars through checkpoints to leave.

“We lived a night of horror. I still cannot believe that I am right here standing on my own two feet,” said Ahmad Shaikho. “So far the situation has been calm. There hasn’t been any gunfire.”

Syrian Civil Defense first responders have been disarming improvised mines that they say were left by the Kurdish forces as booby traps.

Residents who fled are not being allowed back into the neighborhood until all the mines are cleared. Some were reminded of the displacement during Syria’s long civil war.

“I want to go back to my home, I beg you,” said Hoda Alnasiri.
