Propulsion failure threatens US Moon mission

Published

on

The company behind America’s latest mission to soft-land on the Moon is battling to save the project.

Pittsburgh-based Astrobotic says its Peregrine spacecraft has a faulty propulsion system that’s lost “critical” amounts of fuel. The issue has already made it difficult for the craft to point its solar panels at the Sun to generate electricity and may now scupper the planned touch-down.

Astrobotic has begun talking about reassessing its mission goals. In other words, it’s thinking about what can be salvaged from its original objectives.

The 1.2-tonne lander was launched early on Monday from Cape Canaveral, Florida, on a Vulcan rocket. Its aim was to become the first American mission in half a century to make a controlled landing on the Moon and the first ever commercial endeavour to achieve the feat.

The US space agency (Nasa) had purchased capacity on the lander for five instruments to study the lunar surface environment ahead of sending astronauts there later this decade.

Peregrine’s problems emerged shortly after communications had been established with ground controllers, following its release from the top of the Vulcan. Engineers noticed the spacecraft was struggling to maintain a stable lock on the Sun, meaning its solar cells were not receiving a constant supply of sunshine to recharge the onboard battery. Power levels were reported to be reaching operationally low levels.

Astrobotic’s engineers eventually identified the root cause as a failure in the propulsion system, a situation apparently confirmed by a picture from the craft showing disturbed layers of insulation. And although they were able to successfully re-point the spacecraft and charge the battery, it was evident, the company said, that Peregrine was losing propellant. “The team is working to try and stabilise this loss, but given the situation we have prioritised maximising the science and data we can capture,” a statement read. “We are currently assessing what alternative mission profiles may be feasible at this time.”

Astrobotic is the first of three US companies to send a lander to the Moon this year under a new private-public partnership with Nasa.

The agency is buying transport services from the Pittsburgh firm and two other commercial ventures – Intuitive Machines and Firefly. Together, the trio had planned six missions to the lunar surface in 2024.

All three US companies have Nasa as a “customer”, but the agency is “not in charge” of their projects. It is the firms themselves who have designed the spacecraft and are in command as the missions progress.

Nasa believes this arrangement will introduce more innovation and reduce costs over time. And the agency says it is prepared for some of the missions not to work.

Speaking to the BBC last month, deputy administrator Pam Melroy, said: “What we have learned from our commercial partners is if we have a high enough cadence, we can relax some of the requirements that make it so costly, and have a higher risk appetite. And if they fail, the next one is going to learn and succeed.”

Meta blocks 550,000 accounts under Australia’s social media ban

Australia's landmark socual media ban for kids is being watched closely around the world (BBC)

About 550,000 accounts were blocked by Meta during the first days of Australia’s landmark social media ban for kids.

In December, a new law began requiring that the world’s most popular social media sites – including Instagram and Facebook – stop Australians aged under 16 from having accounts on their platforms.

The ban, which is being watched closely around the world, was justified by campaigners and the government as necessary to protect children from harmful content and algorithms.

Companies including Meta have said they agree more is needed to keep young people safe online. However they continue to argue for other measures, with some experts raising similar concerns.

“We call on the Australian government to engage with industry constructively to find a better way forward, such as incentivising all of industry to raise the standard in providing safe, privacy-preserving, age appropriate experiences online, instead of blanket bans,” Meta said in a blog update.

The company said it blocked 330,639 accounts on Instagram, 173,497 on Facebook, and 39,916 on Threads during it’s first week of compliance with the new law.

They again put the argument that age verification should happen at an app store level – something they suggested lowers the burden of compliance on both regulators and the apps themselves – and that exemptions for parental approval should be created.

“This is the only way to guarantee consistent, industry-wide protections for young people, no matter which apps they use, and to avoid the whack-a-mole effect of catching up with new apps that teens will migrate to in order to circumvent the social media ban law.”

Various governments, from the US state of Florida to the European Union, have been experimenting with limiting children’s use of social media. But, along with a higher age limit of 16, Australia is the first jurisdiction to deny an exemption for parental approval in a policy like this – making its laws the world’s strictest.

The policy is wildly popular with parents and envied by world leader, with the Tories this week pledging to follow suit if they win power at the next election, due before 2029.

However some experts have raised concerns that Australian kids can circumvent the ban with relative ease – either by tricking the technology that’s performing the age checks, or by finding other, potentially less safe, places on the net to gather.

And backed by some mental health advocates, many children have argued it robs young people of connection – particularly those from LGBTQ+, neurodivergent or rural communities – and will leave them less equipped to tackle the realities of life on the web.

A newly married couple were killed when a gas cylinder exploded at a house in Islamabad where they were sleeping after their wedding party, police have said.

A further six people – including wedding guests and family members – who were staying there also died in the blast. More than a dozen people were injured.

The explosion took place at 07:00 local time (02:00 GMT) on Sunday, causing the roof to collapse.

Parts of the walls were blown away, leaving piles of bricks, large concrete slabs and furniture strewn across the floor. Injured people were trapped under the rubble and had to be carried out on stretchers by rescue workers.

Rescuers race to find dozens missing in deadly Philippines landfill collapse

More than 30 people are thought to be missing following the landslide in Cebu [BBC]

Rescue workers are racing to find dozens of people still missing following a landslide at a landfill site in the central Philippines that occurred earlier this week, an official has said.

Mayor Nestor Archival said on Saturday that signs of life had been detected at the site in Cebu City, two days after the incident.

Four people have been confirmed dead so far, Archival said, while 12 others have been taken to hospital.

Conditions for emergency services working at the site were challenging, the mayor added, with unstable debris posing a hazard and crew waiting for better equipment to arrive.

The privately-owned Binaliw landfill collapsed on Thursday while 110 workers were on site, officials said.

Archival said in a Facebook post on Saturday morning: “Authorities confirmed the presence of detected signs of life in specific areas, requiring continued careful excavation and the deployment of a more advanced 50-ton crane.”

Relatives of those missing have been waiting anxiously for any news of their whereabouts. More than 30 people, all workers at the landfill, are thought to be missing.

“We are just hoping that we can get someone alive… We are racing against time, that’s why our deployment is 24/7,” Cebu City councillor Dave Tumulak, chairman of the city’s disaster council, told news agency AFP.

Jerahmey Espinoza, whose husband is missing, told news agency Reuters at the site on Saturday: “They haven’t seen him or located him ever since the disaster happened. We’re still hopeful that he’s alive.”

The cause of the collapse remains unclear, but Cebu City councillor Joel Garganera previously said it was likely the result of poor waste management practices.

Operators had been cutting into the mountain, digging the soil out and then piling garbage to form another mountain of waste, Garganera told local newspaper The Freeman on Friday.

The Binaliw landfill covers an area of about 15 hectares (37 acres).

Landfills are common in major Philippine cities like Cebu, which is the trading centre and transportation gateway of the Visayas, the archipelago nation’s central islands.
