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.”

North Korea cancels Pyongyang Marathon for ‘some reasons’

The annual marathon is usually held in April [BBC]

North Korea has cancelled the Pyongyang marathon for unspecified reasons, a tour agency linked to the event has said.

British-owned Koryo Tours, which describes itself as the official partner of the marathon, said on Monday that it had received notice of the cancellation from North Korea’s athletics association.

A message it attributed to the association said the marathon was being cancelled “due to some reasons”.

The annual event was established in 1981 to celebrate the birth of North Korea’s founding leader Kim Il Sung. The 2026 race was set to take place on 5 April.

The message, purportedly from the North Korea athletics association’s general secretary, thanked “all the Elite Marathoners and Amateur Runners of the world who are interested in Pyongyang International Marathon”.

The message gave no further explanation on what the reasons for the cancellation were.

Koryo Tours said it understood the decision was final and had been taken “at a level above the organisers of the event itself”.

It said it would be seeking clarification on the circumstances surrounding the decision.

The tour company added that neither organisers nor event partners were involved in making the decision, and said it recognised “this announcement will be disappointing to many runners who had already registered or were planning to participate”.

Koryo Tours, based in Beijing, China, offers several marathon packages to foreigners, departing from Beijing, Shanghai and Shenyang.

Packages start from €2,190 ($2,529; £1,894) for 2.5 nights in the North Korean capital, Pyongyang, including a marathon place and “highlights” of the capital and tickets were sold out this year, according to the agency’s website.

It said all deposits paid will be returned and runners have the option to retain their deposit for a future event or North Korea tour.

A date for the 2027 marathon has not yet been set.

The event had only returned last year after it was suspended for five consecutive years due to the Covid pandemic.

It is open to both amateur and some professional athletes and offers several race distances – 5km (3.1 miles), 10km (6.2 miles), half marathon (21.1km; 13.1 miles) or full marathon (42.2km; 26.2 miles).

Canadian officials rescue 23 people who floated away on ice sheet

Published

Twenty-three people have been rescued by helicopter crews in Ontario, Canada, after the ice shelf they were standing on broke, sending the group floating into Lake Huron.

Ontario Provincial Police said on social media that the rescue began around noon (16:00 GMT) on Sunday after “winds and current moved the ice shelf away from shore” approximately 2km (1.2 miles).

The rescue involved two helicopters making multiple trips to pluck people off the shelf as it continued to fracture into more pieces in the Owen Sound, about 200km north-west of Toronto.

One member of the group said that he only realised the ice he was fishing on had detached from shore when he noticed that his GPS showed him moving.

Members of the rescued group described harrowing moments, with several of them becoming partially submerged in the cold waters as they sought out the thickest ice on the floe, or sheet.

“I looked at my GPS. We were moving,” fisherman Kevin Fox wrote, identifying himself on Facebook as one of those who were caught up in the incident. “I turned around and saw waves forming behind us.”

He said that he and several others started running towards a route that they hoped still connected to shore.

“We decided to run toward one side of the bay, but when we got there the ice had already separated from shore. We turned and ran the other way, but the ice there was breaking apart too,” he wrote.

Some started phoning their families, said Fox, adding: “It’s something I will never forget – seeing grown men crying while saying goodbye to the people they love.”

Fellow fisherman Alfie How told The Owen Sound Sun Times that they eventually “just sat down as a group and said this could be the end”.

Fox told the paper that the rescue occurred during high wind, and the group was concerned that the helicopters would not be able to fly.

“It was being eroded,” Fox said. “It kept getting smaller, and smaller.”

Police say several members of the group suffered hypothermia, but that everyone was expected to make a full recovery.

“Great teamwork and a quick response by all involved,” police added.

Last month in the US state of Vermont, police rescued a group of ice skaters who had also become trapped on floating ice.

Using kayaks and ferry boats, rescuers brought the group back from the icy Lake Champlain.

Officials warn that ice fishing conditions can change rapidly during the relatively warm daylight hours.

At least 23 people have been killed in Nairobi after heavy rain overnight caused severe flooding in Kenya’s capital city.

Police said about 30 people had been rescued but many others drowned after being swept into rivers – some have been electrocuted.

Kenya’s military has been deployed to help people trapped inside their cars as police described widespread damage to properties as well as road closures.

Several flights bound for Nairobi Airport had to be cancelled or diverted to the coastal city of Mombasa.

“The torrential rains have led to significant flooding, unfortunately resulting in 23 fatalities so far, the destruction of property, road closures, and the displacement of residents,” police said in a statement on Saturday afternoon.
