China completes historic Mars spacecraft landing

Published

An uncrewed Chinese spacecraft successfully landed on the surface of Mars on Saturday, state news agency Xinhua reported, making China the second space-faring nation after the United States to land on the Red Planet.

The Tianwen-1 spacecraft landed on a site on a vast plain known as Utopia Planitia, “leaving a Chinese footprint on Mars for the first time,” Xinhua said.

Chinese President Xi Jinping issued a message of congratulations to all the people involved in the mission.

“You were brave enough for the challenge, pursued excellence and placed our country in the advanced ranks of planetary exploration,” he said. “Your outstanding achievement will forever be etched in the memories of the motherland and the people.”

The craft left its parked orbit at about 1700 GMT Friday (0100 Beijing time Saturday). The landing module separated from the orbiter three hours later and entered the Martian atmosphere, the official China Space News said.

It said the landing process consisted of “nine minutes of terror” as the module decelerates and then slowly descends.

The official landing time was 2318 GMT (0718 Beijing time), Xinhua said, citing the China National Space Administration. The rover took more than 17 minutes to unfold its solar panels and antenna and send signals to ground controllers more than 320 million kilometres away.

The rover, named Zhurong, will now survey the landing site before departing from its platform to conduct inspections. Named after a mythical Chinese god of fire, Zhurong has six scientific instruments including a high-resolution topography camera.

It will study the planet’s surface soil and atmosphere. Zhurong will also look for signs of ancient life, including any sub-surface water and ice, using a ground-penetrating radar.

Tianwen-1, or “Questions to Heaven”, after a Chinese poem written two millennia ago, is China’s first independent mission to Mars. A probe co-launched with Russia in 2011 failed to leave the Earth’s orbit.

The five-tonne spacecraft blasted off from the southern Chinese island of Hainan in July last year, launched by the powerful Long March 5 rocket.

After more than six months in transit, Tianwen-1 reached the Red Planet in February where it had been in orbit since.

If Zhurong is successfully deployed, China would be the first country to orbit, land and release a rover in its maiden mission to Mars.

Tianwen-1 was one of three that reached Mars in February, with U.S. rover Perseverance successfully touching down on Feb. 18 in a huge depression called Jezero Crater, more than 2,000 km away from Utopia Planitia.

Hope – the third spacecraft that arrived at Mars in February this year – is not designed to make a landing. Launched by the United Arab Emirates, it is currently orbiting above Mars gathering data on its weather and atmosphere.

The first successful landing ever was made by NASA’s Viking 1 in July 1976 and then by Viking 2 in September that year. A Mars probe launched by the former Soviet Union landed in December 1971, but communication was lost seconds after landing.

China is pursuing an ambitious space programme. It is testing reusable spacecraft and is also planning to establish manned lunar research station.

In a commentary published on Saturday, Xinhua said China was “not looking to compete for leadership in space” but was committed to “unveiling the secrets of the universe and contributing to humanity’s peaceful use of space.”

Australia social media ban set to take effect, sparking a global crackdown

For the social media businesses, the implementation marks a new era of structural stagnation as user numbers flatline and time spent on platforms shrinks, studies show.

Australia is set to become the first country to implement a minimum age for social media use on Wednesday, with platforms like Instagram, TikTok and YouTube forced to block more than a million accounts, marking the beginning of an expected global wave of regulation.

From midnight, 10 of the biggest platforms will be required to block Australians aged under 16 or be fined up to A$49.5 million ($33 million), Reuters reported.

The law received harsh criticism from major technology companies and free speech advocates, but was praised by parents and child advocates.

The rollout closes out a year of speculation about whether a country can block children from using technology that is built into modern life. And it begins a live experiment that will be studied globally by lawmakers who want to intervene directly because they are frustrated by what they say is a tech industry that has been too slow to implement effective harm-minimisation efforts.

Governments from Denmark to Malaysia – and even some states in the U.S., where platforms are rolling back trust and safety features – say they plan similar steps, four years after a leak of internal Meta (META.O) documents showed the company knew its products contributed to body image problems and suicidal thoughts among teenagers while publicly denying the link existed.

“While Australia is the first to adopt such restrictions, it is unlikely to be the last,” said Tama Leaver, a professor of internet studies at Curtin University.

“Governments around the world are watching how the power of Big Tech was successfully taken on. The social media ban in Australia … is very much the canary in the coal mine.”

A spokesperson for the British government, which in July began forcing websites hosting pornographic content to block under-18 users, said it was “closely monitoring Australia’s approach to age restrictions.”

“When it comes to children’s safety, nothing is off the table,” they added.

Few will scrutinise the impact as closely as the Australians. The eSafety Commissioner, an Australian regulator tasked with enforcing the ban, hired Stanford University and 11 academics to analyse data on thousands of young Australians covered by the ban for at least two years.

Though the ban covers 10 platforms initially, including Alphabet’s (GOOGL.O), YouTube, Meta’s Instagram and TikTok, the government has said the list will change as new products appear and young users switch to alternatives.

Of the initial 10, all but Elon Musk’s X have said they will comply using age inference – guessing a person’s age from their online activity – or age estimation, which is usually based on a selfie. They might also check with uploaded identification documents or linked bank account details.

Musk has said the ban “seems like a backdoor way to control access to the internet by all Australians” and most platforms have complained that it violates people’s right to free speech.

For the social media businesses, the implementation marks a new era of structural stagnation as user numbers flatline and time spent on platforms shrinks, studies show.

Platforms say they don’t make much money showing advertisements to under-16s, but they add that the ban interrupts a pipeline of future users. Just before the ban took effect, 86% of Australians aged 8 to 15 used social media, the government said.

“The days of social media being seen as a platform for unbridled self-expression, I think, are coming to an end,” said Terry Flew, the co-director of University of Sydney’s Centre for AI, Trust and Governance.

Platforms responded to negative headlines and regulatory threats with measures like a minimum age of 13 and extra privacy features for teenagers, but “if that had been the structure of social media in the boom period, I don’t think we’d be having this debate,” he added.

Ethiopian volcano erupts for first time in nearly 12,000 years

Ash from the eruption drifted across the region, spreading over Yemen, Oman, India, and parts of Pakistan.

The Hayli Gubbi volcano in Ethiopia’s Afar region has erupted for the first time in almost 12,000 years, sending massive ash plumes soaring up to 14 kilometres into the atmosphere, according to the Toulouse Volcanic Ash Advisory Centre.

The eruption began on Sunday and lasted several hours. Hayli Gubbi, located around 800 kilometres northeast of Addis Ababa near the Eritrean border, sits within the geologically active Rift Valley, where two major tectonic plates meet. The volcano rises roughly 500 metres above the surrounding landscape.

Ash from the eruption drifted across the region, spreading over Yemen, Oman, India, and parts of Pakistan. Satellite imagery and social-media videos captured a towering column of white smoke billowing into the sky.

The Smithsonian Institution’s Global Volcanism Program notes that Hayli Gubbi has no recorded eruptions during the Holocene, the period dating back about 12,000 years to the end of the last Ice Age.

Volcanologist Simon Carn of Michigan Technological University also confirmed on Bluesky that the volcano had “no record of Holocene eruptions.”

Cloudflare outage easing after millions of internet users affected

Published

on

A global outage at web-infrastructure firm Cloudflare began to ease on Tuesday afternoon after preventing people from accessing major internet platforms, including X and ChatGPT.

Cloudflare, whose network handles around a fifth of web traffic, said it started to investigate the internal service degradation around 6:40 a.m. ET. It has deployed a fix but some customers might still be impacted as it recovers service.

The incident marked the latest hit to major online services. An outage of Amazon’s cloud service last month caused global turmoil as thousands of popular websites and apps, including Snapchat, were inaccessible due to the disruption.

Cloudflare – whose shares were down about 5% in premarket trading – runs one of the world’s largest networks that helps websites and apps load faster and stay online by protecting them from traffic surges and cyberattacks.

The latest outage prevented users from accessing platforms such as Canva, X, and ChatGPT, prompting users to log outage reports with Downdetector.

Downdetector tracks outages by collating status reports from a number of sources. “We saw a spike in unusual traffic to one of Cloudflare’s services beginning at 11:20 UTC. That caused some traffic passing through Cloudflare’s network to experience errors,” the company said in an emailed statement.

“We are all hands on deck to make sure all traffic is served without errors.”
