N. Korean satellite plunges into sea after rocket failure

Published

on

A North Korean satellite launch on Wednesday ended in failure, sending the booster and payload plunging into the sea, North Korean state media said, and the South’s military said it had recovered parts of the launch vehicle, Reuters reported.

The new “Chollima-1” satellite launch rocket failed because of instability in the engine and fuel system, state news agency KCNA reported.

The flight was the nuclear-armed state’s sixth satellite launch attempt, and the first since 2016. It was supposed to put North Korea’s first spy satellite in orbit.

It prompted emergency alerts and brief evacuation warnings in parts of South Korea and Japan. The notices were withdrawn with no danger or damage reported.

South Korea’s Joint Chiefs of Staff said on Wednesday the military was conducting a salvage operation to recover what is believed to be parts of the space launch vehicle. The military shared pictures of debris pulled from the water.

Officials from the United States, Japan, South Korea held a phone call, where they “strongly condemned” the launch, Japan’s foreign ministry said.

“The three countries will stay vigilant with high sense of urgency”, the statement said.

North Korea had said it would launch its first military reconnaissance satellite between May 31 and June 11 to boost monitoring of U.S. military activities.

South Korea last week placed satellites in orbit with a domestically designed and produced rocket for the first time, and China sent three astronauts to its space station as part of crew rotation on Tuesday, read the report.

The rocket plunged into the sea “after losing thrust due to the abnormal starting of the second-stage engine,” KCNA reported, in an unusually candid admission of a technical failure by the North.

Pyongyang’s National Aerospace Development Administration (NADA) will investigate the “serious defects” and take action to overcome them before conducting a second launch as soon as possible, KCNA said.

In data provided to international authorities, North Korea said the launch would carry the rocket south, with stages and other debris expected to fall over the Yellow Sea and into the Pacific Ocean.

Air raid sirens wailed across the South Korean capital of Seoul about 6:32 a.m. (2132 GMT Tuesday) as the city warned citizens to prepare for a potential evacuation. Later alerts said the city warning had been a mistake.

“I was so panicked. Nine-one-one lines were busy and the internet was slow,” said Lee Juyeon, 33, a resident in the city of 9 million who was preparing to shelter in a basement with her young child before learning it was a false alarm.

Calm quickly returned in Seoul, while South Korean stocks (.KS11) and the won currency traded firmer.

The Japanese government also issued an emergency warning over its J-Alert broadcasting system for residents of the southern prefecture of Okinawa to take cover indoors early on Wednesday morning.

It later said the rocket would not fly into Japanese territory and lifted the warnings.

On Tuesday, Ri Pyong Chol, vice-chairman of the Central Military Commission of North Korea’s ruling Workers’ Party, said ongoing joint military exercises by the U.S. and South Korea required Pyongyang to have the “means capable of gathering information about the military acts of the enemy in real time.”

The White House condemned a launch using ballistic missile technology and said in a statement it was assessing the situation in coordination with allies, Reuters reported.

Japan’s Chief Cabinet Secretary Hirokazu Matsuno said North Korea’s rocket disappeared from radar above the Yellow Sea and did not make it into space, and added the government had no further information to share now.

“We strongly condemn North Korea’s actions,” he said. Tokyo lodged a complaint to Pyongyang through diplomatic channels in Beijing, he said.

Before Wednesday’s launch, the U.S. State Department said any North Korean launch that used ballistic missile technology would violate multiple United Nations Security Council resolutions.

“Space launch vehicles (SLVs) incorporate technologies that are identical to, and interchangeable with, those used in ballistic missiles, including intercontinental ballistic missiles,” a State Department spokesperson said.

North Korea has attempted five other satellite launches, with two placed in orbit, including during its last such launch in 2016. Its capacity for constructing working satellites remains unproven, however, analysts say.

“To the best of our knowledge, North Korea has a very limited capacity to build satellites,” said Brian Weeden of the Secure World Foundation, a U.S.-based space policy and security organisation. “They have launched a couple of satellites before, but all of them failed immediately after launch or shortly thereafter and none of them appeared to have any significant capability.”

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.

Published

on

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

Published

on

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 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.
