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

South Korea authorities launch probe after three die in Hyundai car test
The Ulsan plant is Hyundai’s biggest manufacturing facility, with its own port and an annual production capacity of 1.4 million vehicles
South Korean authorities launched an investigation on Tuesday after three people died during a car test at a Hyundai Motor plant in the city of Ulsan, police told Reuters.
The two Hyundai researchers and one Hyundai contractor were found unconscious in a car at around 3:00 p.m. while they were testing it in a "chamber," according to Hyundai's labour union.
South Korean media reports said the three had suffocated.
A police officer in Ulsan said the police and the labour ministry were investigating the incident, including its cause.
A fire department official told Reuters that it first received a report at 3:17 pm that the accident happened at Hyundai's No.4 factory.
"Hyundai Motor Company is deeply saddened by the incident that occurred at our plant in Ulsan, South Korea," Hyundai said in a statement, saying it would "cooperate fully with all relevant authorities to determine the cause of this incident."
The Ulsan plant is Hyundai's biggest manufacturing facility, with its own port and an annual production capacity of 1.4 million vehicles, including exports of 1.1 million units.
In November last year, Hyundai Motor broke ground on a 2 trillion won ($1.44 billion) plant in Ulsan dedicated to making electric vehicles in South Korea, as the automaker accelerated a shift away from petrol-powered cars.

Russia fines Google more than the world’s total GDP over YouTube bans
Russia has fined Google $2.5 decillion after the US tech giant took action against pro-Kremlin TV channels on YouTube following Moscow’s invasion of Ukraine.
Russia imposed a daily fine four years ago - a fine that has since swelled to an unprecedented level - ($20,000,000,000,000,000,000,000,000,000,000,000 - a 33-digit figure).
To put this into perspective, global GDP reaches an estimated $110 thousand billion (12-digit figure), according to the IMF.
Speaking to Russia’s TASS news agency, one expert, Roman Yankovsky from the HSE Institute of Education, said Google “clearly will not pay this penalty, and the Russian Federation will not be able to recover this money from the company."
Euronews reported that a short calculation shows that he is right.
Google's holding company, Alphabet, has a market capitalisation of slightly more than $2 trillion. Even with earnings of $80.54 billion from the last quarter, the tech giant doesn’t seem to be able to afford to pay the fine.
Google first barred pro-Moscow channel Tsargrad TV, which is owned by oligarch Konstantin Malofeev, four years ago.
At the time, Google was fined a daily penalty of 100,000 roubles and warned that amount would double every 24 hours if it went unpaid.
The original fine has been compounded by further penalties after Google eventually blocked a total of 17 Russian TV channels as a result of international sanctions, The Telegraph reported.
The tech giant now owes a staggering $2.5 decillion.

Apple launches new iPad mini with AI features
Apple said it would roll out the first set of AI features in the U.S. version of the English language this month through a software update with iPadOS 18.1.
Apple on Tuesday launched its new generation of the iPad mini packed with AI features including writing tools and an improved Siri assistant, as the iPhone maker races to boost its devices with artificial-intelligence capabilities, Reuters reported.
The new iPad mini is powered by Apple's A17 Pro chip, which is used in the iPhone 15 Pro and Pro Max models. With a six-core central processing unit, the A17 Pro would boost CPU performance by 30% compared to the current generation iPad minis and is central to running Apple Intelligence, Apple's AI software.
Apple said it would roll out the first set of AI features in the U.S. version of the English language this month through a software update with iPadOS 18.1.
The features will be available for iPads with A17 Pro or M1 chips and later generations, Apple said, adding it will roll out additional features including image-generation tools, Genmoji and ChatGPT-powered capabilities over the next several months, read the report.
Apple in September unveiled its long-awaited, AI-boosted iPhone 16 lineup, but with the AI features still in test mode, the company failed to excite some investors while early sales data raised some questions around demand.
Still, research firm Canalys on Monday said the iPhone 16 would help Apple's sales in the fourth quarter and drive momentum into the first half of 2025, after Apple reached a record high third-quarter shipments.
The iPad mini, starting at $499, is available for pre-orders starting on Tuesday and will begin arriving to customers and Apple store locations next week, Apple said.
