NASA spacecraft launched to mysterious metal asteroid

Published

NASA’s Psyche spacecraft rocketed away Friday on a six-year journey to a rare metal-covered asteroid.

Most asteroids tend to be rocky or icy, and this is the first exploration of a metal world. Scientists believe it may be the battered remains of an early planet’s core, and could shed light on the inaccessible centers of Earth and other rocky planets, Associated Press.

SpaceX launched the spacecraft into an overcast midmorning sky from NASA’s Kennedy Space Center. Named for the asteroid it’s chasing, Psyche should reach the huge, potato-shaped object in 2029.

An hour later, the spacecraft separated successfully from the rocket’s upper stage and floated away, drawing applause from ground controllers.

After decades of visiting faraway worlds of rock, ice and gas, NASA is psyched to pursue one coated in metal. Of the nine or so metal-rich asteroids discovered so far, Psyche is the biggest, orbiting the sun in the outer portion of the main asteroid belt between Mars and Jupiter alongside millions of other space rocks. It was discovered in 1852 and named after Greek mythology’s captivating goddess of the soul.

“It’s long been humans’ dream to go to the metal core of our Earth. I mean, ask Jules Verne,” lead scientist Lindy Elkins-Tanton of Arizona State University said ahead of the launch.

“The pressure is too high. The temperature is too high. The technology is impossible,” she said. “But there’s one way in our solar system that we can look at a metal core and that is by going to this asteroid.”

Astronomers know from radar and other observations that the asteroid is big — about 232 kilometers across at its widest and 280 kilometers long. They believe it’s brimming with iron, nickel and other metals, and quite possibly silicates, with a dull, predominantly gray surface likely covered with fine metal grains from cosmic impacts.

Russia plans a nuclear power plant on the moon within a decade

Published

Russia plans to put a nuclear power plant on the moon in the next decade to supply its lunar space programme and a joint Russian-Chinese research station, as major powers rush to explore the earth’s only natural satellite.

Ever since Soviet cosmonaut Yuri Gagarin became the first human to go into space in 1961, Russia has prided itself as a leading power in space exploration, but in recent decades it has fallen behind the United States and, increasingly, China, Reuters reported.

Russia’s ambitions suffered a massive blow in August 2023 when its unmanned Luna-25 mission smashed into the surface of the moon while attempting to land, and Elon Musk has revolutionised the launch of space vehicles – once a Russian speciality.

IS THAT A NUCLEAR REACTOR ON THE MOON?

Russia’s state space corporation, Roscosmos, said in a statement that it planned to build a lunar power plant by 2036 and signed a contract with the Lavochkin Association aerospace company to do it.

Roscosmos did not say explicitly that the plant would be nuclear but it said the participants included Russian state nuclear corporation Rosatom and the Kurchatov Institute, Russia’s leading nuclear research institute.

Roscosmos said the purpose of the plant was to power Russia’s lunar programme, including rovers, an observatory and the infrastructure of the joint Russian-Chinese International Lunar Research Station.

“The project is an important step towards the creation of a permanently functioning scientific lunar station and the transition from one-time missions to a long-term lunar exploration programme,” Roscosmos said.

The head of Roscosmos, Dmitry Bakanov, said in June that one of the corporation’s aims was to put a nuclear power plant on the moon and to explore Venus, known as earth’s “sister” planet.

The moon, which is 384,400 km (238,855 miles) from our planet, moderates the earth’s wobble on its axis, which ensures a more stable climate. It also causes tides in the world’s oceans.

U.S. ALSO PLANS A REACTOR ON THE MOON

Russia is not the only one with such plans. NASA in August declared its intent to put a nuclear reactor on the moon by the first quarter of fiscal year 2030.

“We’re in a race to the moon, in a race with China to the moon. And to have a base on the moon, we need energy,” U.S. Transport Secretary Sean Duffy said in August, when asked about the plans.

He added that the United States was currently behind in the race to the moon. He said energy was essential to allow life to be sustained on the moon and thence for humans to get to Mars.

International rules ban putting nuclear weapons in space but there are no bans on putting nuclear energy sources into space – as long as they comply with certain rules.

Some space analysts have predicted a lunar gold rush: NASA says there are estimates of a million tonnes of Helium-3, an isotope of helium that is rare on earth, on the moon.

Rare earth metals – used in smartphones, computers and advanced technologies – are also present on the moon, including scandium, yttrium and the 15 lanthanides, according to research by Boeing.

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.”
