The inaugural launch of Japan’s next-generation rocket yesterday was aborted shortly after takeoff after the Japan Aerospace Exploration Agency (JAXA) ordered it to self-destruct and plunge into the ocean, dealing a blow to the nation’s aspirations to take on Elon Musk’s Space Exploration Technologies Corp (SpaceX).
JAXA decided to scrap the mission after the H3 rocket’s second-stage engine failed to ignite, the agency said.
The self-destruct signal was sent to the craft about 19 minutes after it lifted off from Tanegashima Space Center in southwestern Japan, shutting down the engine and forcing the portion carrying a satellite into the Philippine Sea.

The 63m-tall spacecraft, built by Mitsubishi Heavy Industries Ltd, represented Japan’s latest attempt to capitalize on growing demand in the global space industry.
SpaceX has been launching and remotely landing its Falcon orbital rockets since 2015. The H3, on the other hand, has large parts that can be recycled and is more competitively priced, but the rocket itself cannot be landed and launched again.
“It’s our duty to figure out the root cause of the malfunction and eventually restore trust in the rocket,” JAXA president Hiroshi Yamakawa said at a news conference. “The H3 is crucial for Japan’s hopes to reach space.”
A task force was created to investigate what caused the malfunction. JAXA said it had no plans to recover the fallen engine.
Mitsubishi Heavy worked on the H3 for more than a decade. A previous launch attempt on Feb. 17 was aborted before liftoff after a system malfunction from the main engine stopped an ignition signal from reaching its side booster.
The H3 was supposed to launch from the island and deliver a satellite known as DAICHI-3 into orbit.
The satellite was equipped with various instruments, including a sensor designed to detect missile launches that was set to be tested in space for the first time by the Japanese Ministry of Defense.
While rockets with large payload capacities account for a fraction of the global space economy, the commercial satellite industry generated US$386 billion in 2021 and continues to grow, Satellite Industry Association data showed.
The H3 is meant to replace the H2-A, which was first introduced in 2001, as the nation’s flagship rocket. As nations race to claim their slice of a growing aerospace market, JAXA said it aims to launch six satellites into space a year for the next two decades.
For a long time, the main issue was price. At about US$90 million a launch, the H2-A had a similar payload capacity, but came at a greater price than the Falcon 9 booster from SpaceX, which costs US$67 million per launch. Launching the H3 once would cost about US$50 million, JAXA said.
“To the many onlookers, admirers and people involved in the development and launch of the H3, we sincerely apologize,” Yamakawa said.
The Philippine Department of Justice yesterday labeled Vice President Sara Duterte the “mastermind” of a plot to assassinate the nation’s president, giving her five days to respond to a subpoena. Duterte is being asked to explain herself in the wake of a blistering weekend press conference where she said she had instructed that Philippine President Ferdinand Marcos Jr be killed should an alleged plot to kill her succeed. “The government is taking action to protect our duly elected president,” Philippine Undersecretary of Justice Jesse Andres said at yesterday’s press briefing. “The premeditated plot to assassinate the president as declared by the self-confessed mastermind
Texas’ education board on Friday voted to allow Bible-infused teachings in elementary schools, joining other Republican-led US states that pushed this year to give religion a larger presence in public classrooms. The curriculum adopted by the Texas State Board of Education, which is controlled by elected Republicans, is optional for schools to adopt, but they would receive additional funding if they do so. The materials could appear in classrooms as early as next school year. Republican Texas Governor Greg Abbott has voiced support for the lesson plans, which were provided by the state’s education agency that oversees the more than
Ireland, the UK and France faced travel chaos on Saturday and one person died as a winter storm battered northwest Europe with strong winds, heavy rain, snow and ice. Hampshire Police in southern England said a man died after a tree fell onto a car on a major road near Winchester early in the day. Police in West Yorkshire said they were probing whether a second death from a traffic incident was linked to the storm. It is understood the road was not icy at the time of the incident. Storm Bert left at least 60,000 properties in Ireland without power, and closed
CONSPIRACIES: Kano suspended polio immunization in 2003 and 2004 following claims that polio vaccine was laced with substances that could render girls infertile Zuwaira Muhammad sat beside her emaciated 10-month-old twins on a clinic bed in northern Nigeria, caring for them as they battled malnutrition and malaria. She would have her babies vaccinated if they regain their strength, but for many in Kano — a hotbed of anti-vaccine sentiment — the choice is not an obvious one. The infants have been admitted to the 75-bed clinic in the Unguwa Uku neighbourhood, one of only two in the city of 4.5 million run by French aid agency Doctors Without Borders (MSF). Kano has the highest malaria burden in Nigeria, but the city has long
