Japan successfully launches next-generation H3 rocket after failure last year
Japan successfully launched its new H3 flagship rocket on Saturday, putting its space programme back on track after multiple setbacks including the failure of the rocket’s inaugural flight last year.
The launch also marks a second straight win for the Japan Aerospace Exploration Agency (JAXA) after its lunar lander, SLIM, achieved a “pinpoint” touchdown last month and made Japan only the fifth country to put a spacecraft on the moon, Reuters reported.
A relatively small player in space by number of launches, Japan is seeking to revitalise its programme as it partners with ally the United States to counter China.
The H3 lifted off at 9:22 a.m. local time (0022 GMT) and after it successfully released a small satellite, jubilant scientists at the Tanegashima Space Center in southern Japan clapped, yelled and hugged each other.
The rocket also released a microsatellite and a dummy satellite during its flight of nearly two hours.
“The newborn H3 has just made its first cry”, JAXA project manager Masashi Okada, who has led the decade-long development of the new rocket, told a news conference.
“And we need to start preparing for the third H3 launch as soon as tomorrow.”
The H3 is due to replace the two-decade-old H-IIA, which is retiring after two more launches. Another failed flight would have seen Japan face the prospect of losing independent access to space.
The first launch in March ended up with ground control destroying the rocket 14 minutes after liftoff when the second-stage engine failed to ignite. JAXA listed three possible electrical faults in a review released in October but could not identify the direct cause.
Five months earlier, JAXA’s small rocket Epsilon had also failed to launch.
“So happy to see this incredible accomplishment in the space sector that follows on from the success of the SLIM moon landing,” Prime Minister Fumio Kishida said in a post on X.
The 63 m (297 ft) H3 is designed to carry a 6.5 metric ton payload and over the long-term, the agency wants to reduce per-launch cost to as low as five billion yen ($33 million) – half of what an H-IIA launch costs – by adopting simpler structures and automotive-grade electronics.
JAXA and primary contractor Mitsubishi Heavy Industries (7011.T), opens new tab hope those features will help them win launch orders from global clients.
“It’s taken some time for the program to get to this point but with this launch, they will be fielding inquiries from around the world,” said Ko Ogasawara, a professor at the Tokyo University of Science.
The Japanese government plans to launch about 20 satellites and probes with H3 rockets by 2030 for domestic use. The H3 is scheduled to deliver a lunar explorer for the joint Japan-India LUPEX project in 2025 as well as cargo spacecraft for the U.S.-led Artemis moon exploration program in the future.
Satellite launch demands have skyrocketed thanks to the rise of affordable commercial vehicles such as SpaceX’s reusable Falcon 9 and a number of new rockets are being tested this year.
Last month marked the successful inaugural flight of the United Launch Alliance’s Vulcan rocket, a joint venture between Boeing (BA.N), opens new tab and Lockheed Martin (LMT.N), opens new tab. The European Space Agency also plans to launch its lower-cost Ariane 6 for the first time this year.
Masayuki Eguchi, the head of Mitsubishi Heavy’s defence and space business, said the company has a long-term target of launching eight to ten rockets a year, which would boost its 50 billion yen space business sales by 20-30%.
That would require additional production capacity, he added, noting the company’s factories can currently only produce five to six H3 rockets a year.

Meta turns off Instagram’s private messaging encryption worldwide
Meta said the decision was based on low user adoption, though critics argue optional privacy tools often see limited use because users must manually activate them.
Instagram has disabled its end-to-end encrypted (E2EE) direct messaging feature worldwide, marking a major reversal by parent company Meta on its previous commitment to stronger user privacy protections.
The move means Instagram users can no longer send ultra-private direct messages protected by E2EE — a security system that allows only the sender and recipient to read messages. Without the feature, Instagram can technically access the content of direct messages, including photos, videos and voice notes.
Meta had previously promoted encryption as “the future is private.” In 2019, CEO Mark Zuckerberg pledged to expand the technology across the company’s platforms.
Facebook Messenger adopted E2EE in 2023, while Instagram introduced it as an optional feature with plans to make it standard.
However, Meta has now abandoned the wider Instagram rollout and updated the app’s terms in March to confirm encrypted messaging would no longer be supported after 8 May 2026.
Meta said the decision was based on low user adoption, though critics argue optional privacy tools often see limited use because users must manually activate them.
The move has divided opinion. Child protection groups, including the NSPCC, welcomed the change, saying encryption can make it harder to detect child grooming and abuse online.
Privacy advocates criticised the decision. Maya Thomas of Big Brother Watch warned the move weakens online privacy protections and could increase pressure on other social media companies to scale back encryption.
End-to-end encryption remains standard on platforms including WhatsApp, Signal, Apple’s iMessage and Google Messages, while other platforms continue to take mixed approaches to private messaging.

James Webb Telescope captures clearest-ever view of exoplanet’s surface
Astronomers using NASA’s James Webb Space Telescope have obtained the clearest view yet of the surface of a rocky exoplanet, revealing a scorched, atmosphere-free world that scientists say resembles a giant version of Mercury.
The planet, known as LHS 3844 b and nicknamed “Kua’kua,” appears to be a barren, uninhabitable world with extreme temperature swings and no detectable atmosphere, according to a study published this week in Nature Astronomy.
Researchers said the planet’s surface is likely covered in dark volcanic rock and ancient regolith — loose rocky debris formed over billions of years from relentless bombardment by radiation and micrometeorite impacts.
“This planet is not a nice place,” said astronomer Laura Kreidberg, senior author of the study. “It’s a hellish, barren rock — much more similar to Mercury than Earth.”
Located about 49 light-years away, LHS 3844 b orbits a small red dwarf star and completes a full orbit every 11 hours. The planet is tidally locked, meaning one side permanently faces its star while the other remains in darkness — similar to how the Moon always shows the same face to Earth.
Scientists found the planet’s dayside reaches roughly 1,340 degrees Fahrenheit (725 degrees Celsius), while the nightside showed almost no detectable heat.
Using Webb’s infrared instruments, researchers were able to directly analyze light coming from the planet’s surface — a major breakthrough for exoplanet science.
“Different rocks have different spectral fingerprints,” said lead author Sebastian Zieba. “Dark volcanic rocks like basalt matched our observations much better than brighter rocks like granite.”
The findings mark a new phase in exoplanet research, shifting beyond atmospheric studies toward direct analysis of alien geology and surface composition.
Since becoming operational in 2022, the Webb telescope has transformed scientists’ understanding of planets beyond the solar system, helping identify atmospheric chemistry, weather patterns and now even the nature of distant planetary surfaces.
Researchers said the absence of an atmosphere on LHS 3844 b means there is little protection from stellar radiation and virtually no possibility of liquid water — a key ingredient for life.
“So overall, this is almost certainly not a habitable world,” Zieba said.

Afghanistan launches first 5G trial in Kabul to boost telecom services
According to ministry spokesperson Enayatullah Alokozai, AWCC has upgraded 74 telecom antennas in Kabul to 5G on a trial basis.
Afghanistan has launched its first-ever 5G telecommunications trial in Kabul, marking a major milestone in efforts to modernise the country’s digital infrastructure.
The announcement followed a meeting between Hamdullah Nomani, Minister of Communications and Information Technology, and Aliullah Sarwari, head of the Afghan Wireless Communication Company (AWCC), where discussions focused on expanding telecom coverage, improving service quality, and extending connectivity to remote regions.
According to ministry spokesperson Enayatullah Alokozai, AWCC has upgraded 74 telecom antennas in Kabul to 5G on a trial basis. Once technical preparations and testing are completed, the company plans to extend 5G services to other provinces.
Officials also reported steady progress on broader infrastructure development. Eight telecom sites approved during previous official visits to northern and southeastern provinces have been completed, one is nearing completion, and construction continues on two additional sites expected to become operational soon.
In parallel, the Afghanistan Telecom Regulatory Authority (ATRA) has approved eight more telecom sites under the Telecom Development Fund (TDF), with implementation scheduled in the coming months.
Sarwari noted that since the beginning of 2026, AWCC has built and activated 46 telecom sites using its development budget, while work continues on a further 186 sites nationwide.
He also thanked the Ministry of Communications and Information Technology for its ongoing support in facilitating sector growth and improving service delivery.
Nomani meanwhile emphasised that telecommunications play a crucial role in national development and said the government remains committed to working closely with operators to expand modern, high-quality digital services.
Officials added that cooperation between the ministry, regulators, and telecom companies will continue across all operational and regulatory areas to strengthen Afghanistan’s communications network.
