N. Korean satellite plunges into sea after rocket failure

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 The notices were withdrawn with no danger or damage reported.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.”

Apple loses top phonemaker spot to Samsung as iPhone shipments drop, IDC says

(Last Updated On: April 16, 2024)

Apple’s (AAPL.O), opens new tab smartphone shipments dropped about 10% in the first quarter of 2024, hurt by intensifying competition by Android smartphone makers aiming for the top spot, data from research firm IDC showed on Sunday.

Global smartphone shipments increased 7.8% to 289.4 million units during January-March, with Samsung (005930.KS), opens new tab, at 20.8% market share, clinching the top phonemaker spot from Apple, Reuters reported.

The iPhone-maker’s steep sales decline comes after its strong performance in the December quarter when it overtook Samsung as the world’s No.1 phone maker. It’s back to the second spot, with 17.3% market share, as Chinese brands such as Huawei gain market share.

Xiaomi, one of China’s top smartphone makers, occupied the third position with a market share of 14.1% during the first quarter, read the report.

South Korea’s Samsung, which launched its latest flagship smartphone lineup – Galaxy S24 series – in the beginning of the year, shipped more than 60 million phones during the period.

Global sales of Galaxy S24 smartphones jumped 8%, compared to last year’s Galaxy S23 series during their first three weeks of availability, data provider Counterpoint previously said.

In the first quarter, Apple shipped 50.1 million iPhones, down from 55.4 million units it shipped same period last year, according to IDC.

Apple’s smartphone shipments in China shrank 2.1% in the final quarter of 2023 from a year earlier.

The drop underscores the challenges facing the U.S. firm in its third biggest market, as some Chinese companies and government agencies limit employees’ use of Apple devices, a measure that mirrors U.S. government restrictions on Chinese apps on security grounds.

The Cupertino, California-based company in June will hold its Worldwide Developers Conference (WWDC), where it will highlight updates to the software powering iPhones, iPads, and other Apple devices.

Investors are closely watching for updates on artificial intelligence development at Apple, which has so far spoken little about incorporating the AI technology into its devices. The company earlier this year lost the crown as the world’s most valuable company to Microsoft (MSFT.O), opens new tab, Reuters reported.

China launch of relay satellite Queqiao-2 for lunar probe mission successful

(Last Updated On: April 12, 2024)

China National Space Administration (CNSA) said on Friday its launch of a key signal relay satellite was a “complete success” and it would serve as the communication bridge for its future lunar probe missions for years to come, state media reported.

China launched the satellite Queqiao-2, which was named after a mythological bridge made of magpies, and two miniature satellites, Tiandu-1 and Tiandu-2, on March 20.

Queqiao-2 will be used as a communications bridge between the ground operations on earth and upcoming lunar probe missions on the far side of the moon until at least 2030.

The moon’s near side always faces earth. That means data transfers from the far side are impossible because there is no direct line of sight.

Queqiao-2 researcher and developer Xiong Liang described the satellite as “the main switch” of the whole fourth phase of lunar missions, according to state television CCTV.

“Only when the main switch is flipped on, all the communications can kick off,” Xiong said.

Queqiao-2 will orbit the moon and relay signals to and from the Chang’e-6 mission, which expected to be launched in May. The robotic Chang’e-6 probe will seek to retrieve samples from an ancient basin, acquiring lunar material from the moon’s hidden side for the first time.

Queqiao-2 will also be used as a relay platform for the Chang’e-7 lunar mission in 2026 and the Chang’e-8 mission in 2028.

The functions and performance of Queqiao-2 met mission requirements and it will be able to provide relay communication services for China’s lunar exploration projects and future lunar missions for China and other countries, said the CNSA, according to CCTV.

Queqiao-2 entered its targeted elliptical orbit on April 2 after a correction midway, near-moon braking and orbital manoeuvre around the moon, CNSA said.

The satellite has successfully communicated with Chang’e 4, which was the first spacecraft to perform a soft landing on the far side of the moon and is still carrying out its exploration mission. It also communicated with the Chang’e-6 probe while it is still on the ground earlier this month.

The successful launch of Queqiao-2 comes after the failed launch of another lunar spacecraft DRO-A/B satellites, which was intended to enter the moon’s distant retrograde orbit (DRO).

China has not released any information on whether or not the satellites can be retrieved.

Russian space officials on Tuesday aborted the test launch of a new heavy-lift rocket from its far-eastern launch pad.

The Angara-A5 rocket was scheduled to lift off from the Vostochny space launch facility at 0900 GMT Tuesday, but the launch was aborted two minutes before, AP reported.

Yuri Borisov, head of Roscosmos state space corporation, said the automatic safety system canceled the launch after registering a flaw in the oxidizer tank pressurization system.

He said the next launch attempt was set for Wednesday.

Tuesday’s launch was to be the fourth for the Angara-A5, a heavy-lift version of the new Angara family of rockets that has been developed to replace the Soviet-designed Proton rockets.
