Artemis 1: Nasa cancels moon mission launch over engine problem

Nasa is delaying a decision on the timing of its next launch attempt for Artemis 1, the US space agency’s first human-rated moon rocket in 50 years, after calling off Monday’s scheduled lift off late in the countdown because of an issue related to “engine bleed”

Engineers at Nasa’s launch complex in Cape Canaveral, Florida, discovered the problem with one of the four core-stage engines of the Space Launch System (SLS) rocket during overnight loading of 2.76m litres (730,000 gallons) of liquid hydrogen and oxygen fuel needed to send the spacecraft off on its 1.3m-mile, 42-day journey to the far side of the moon and back.

They were unable to find a fix in time to meet a two-hour launch window that opened at 8.33am (1.33pm BST) on Monday, and they are now troubleshooting the issue to assess readiness for the next available opportunity, on Friday 2 September.

“Friday is definitely in play. We just need a little bit of time to look at the data, but the team is setting up for a 96-hour recycle,” Mike Sarafin, Nasa’s Artemis mission manager, told a lunchtime press conference.

“We’re going to play all nine innings. We’re not giving up yet.”

Sarafin said no decision could be made until mission managers conducted a readiness review beginning on Tuesday afternoon, noting that he did not believe the problem was with the engine itself, but in the bleed system that “conditions” it with cryogenic propellant and adjusts the temperature for launch.

“The team… also saw an issue with a vent valve at the inner tank, so the combination of not being able to get the engine three chilled down and then the vent valve issue caused us to pause today, and we felt like we needed a little little more time,” he said.

Sarafin added that poor weather conditions at launchpad 39B at Kennedy Space Centre throughout Monday’s window would also have precluded the launch taking place.

The uncrewed Artemis flight is a crucial test mission designed to gauge the capabilities of the SLS rocket and six-person Orion crew capsule ahead of humanity’s planned return to the moon for the first time in half a century.

If Artemis 1 ultimately succeeds, astronauts will be onboard an interim test flight along the same route 40,000 miles beyond the moon and back, a trek scheduled for 2024. The first moon landing since Apollo 17 in December 1972 would follow a year or so later, with Nasa declaring it will carry the first woman to walk on the lunar surface.

Upwards of a quarter-million people flocked to Florida’s space coast on Monday to watch a moment in history now postponed to later this week, or even later in September or October, if engineers cannot quickly diagnose and address the cause of the engine bleed issue.

Problems with the rocket, which is made by Boeing, first arose during a “hot fire” test in January last year, when the engines shut down only one minute into a scheduled eight-minute run. The project at that stage was already almost three years behind schedule and $3bn (£2.55bn) over budget.

Critics say the ultimate cost to the US taxpayer of the Artemis programme, projected to reach $93bn (£79bn) by 2025, and which has longer-term goals of placing the first humans on Mars in 15 to 20 years’ time, cannot be justified.

But the Nasa administrator, Bill Nelson, a former space shuttle astronaut, said there was greater purpose in placing new human footprints in lunar soil now from those of the 12 men of the Apollo programme who did so over six missions in a past generation.

“We need to be on the moon for much longer periods of time than just landing like we used to, stayed a couple of days and left,” Nelson told NBC’s Meet the Press on Sunday. “This time we’re going back, we’re going to live there, we’re going to learn there. We’re going to develop new technologies, all of this so we can go to Mars with humans.

“All of this is to develop where we may be living on other worlds. They may be floating worlds, they may be the surface of Mars. But this is just part of our push outward, our quest to explore, to find out what’s out there in this universe.”

Nasa’s shuttle program, which was retired in 2011, limited crewed missions to lower Earth orbit, and subsequently private US space companies, including Elon Musk’s SpaceX and Jeff Bezos’s Blue Origin, have flown, or are planning flights, to the International Space Station orbiting about 250 miles above Earth.

Artemis is Nasa’s first deep-space exploration project for decades and, unlike the Apollo and shuttle programmes before it, relies heavily on outside contractors and international partners.

SLS is designed and manufactured by Boeing. The Orion crew capsule is the brainchild of Lockheed Martin. And the European Space Agency supplies the service module, the powerhouse of the spacecraft for its lunar journey once the powerful solid rocket boosters and core stage of SLS have placed it beyond Earth’s gravitational pull.

The ESM will push Orion farther from Earth than any human-rated space vehicle has ever flown before, providing electricity, water, oxygen and nitrogen and keeping the capsule on course and at the correct temperature before separating and burning up harmlessly in the atmosphere on its return to Earth.

Hawk Fire in US Rages On, Burns 10,500 Acres in Nevada, Forces Mass Evacuations

Hawk Fire in US Rages On, Burns 10,500 Acres in Nevada, Forces Mass Evacuations

A fast-moving wildfire in the western United States has exploded to over 10,500 acres near Reno, Nevada, forcing thousands to flee their homes as firefighters battle the blaze with zero containment.

RENO, Nevada, US – The Hawk Fire, a rapidly growing wildfire in the western United States, has expanded to cover more than 10,500 acres in Nevada as of late Saturday evening, with firefighters reporting zero containment and challenging conditions driven by gusty winds, low humidity, and dry vegetation. The blaze ignited around 11:30 a.m. on Saturday, August 22, 2026, off the Hawk Meadow Trail near the Somersett community in the foothills of northwest Reno. By mid-afternoon, the fire had grown to approximately 2,500 to 3,000 acres. By 8:30 p.m. Saturday, mapping platform Perimeter Map reported the fire had expanded to at least 10,523 acres.

Approximately 400 personnel from local, state, and federal agencies are currently battling the blaze in the US state of Nevada, with ground crews and air resources deployed to contain the fire. The Nevada National Guard is supporting aerial firefighting operations, deploying one CH-47 Chinook and one UH-60 Black Hawk aircrew to assist with firefighting efforts. An additional 60 Nevada National Guard Response Force personnel have been called in to support local law enforcement in protecting evacuated neighbourhoods. Truckee Meadows Fire Protection District Chief Richard Edwards described the situation as “a very dynamic incident” driven by the wind, noting that “wind-driven fires move very rapidly into our residential areas, creating a lot of challenges for our firefighters to save homes and protect lives.”

Nevada Governor Joe Lombardo has declared a state of emergency in Washoe County as the Hawk Fire continues its rapid spread across the US state. “I have declared a state of emergency in Washoe County as we respond to the Hawk Fire, which is spreading quickly and threatening homes and structures,” Lombardo said. “Please heed all warnings from local officials, evacuate immediately if you are ordered to do so, and do not put yourself or first responders at risk.” Under the declaration, all state agencies are directed to work through the Nevada Emergency Operations Center to supplement local response efforts. “This is an active and rapidly evolving situation, and I urge everyone in the affected areas to remain vigilant and follow the direction of local officials,” Lombardo continued. “The state is fully engaged, and we are working alongside local authorities and first responders to deploy every available resource to protect lives, safeguard communities, and keep Nevadans out of harm’s way.” Reno Mayor Hillary Schieve confirmed that structures have already been burned in the fire and urged residents to prioritise their safety. “Structures have already been burned in this fire and your life is more important than a building,” Schieve said in a message posted by the City of Reno on X.

The Washoe County Sheriff’s Office has issued mandatory “Go Now” evacuation orders for several neighbourhoods as the fire continues to spread. Evacuations have expanded southward, affecting the Somersett community, including areas north of Somersett Parkway to Robb Drive, as well as neighborhoods in northwest Reno. Communities from Raleigh Heights to Red Rock on the west side of U.S. Highway 395 have been instructed to evacuate immediately. U.S. Highway 395 in Washoe County has been closed in both directions between Parr Boulevard and Red Rock Road due to the fire’s proximity. Rancho San Rafael Park has also been closed as the fire continues to spread. The fire has also prompted evacuation warnings in Sierra County, California, as authorities continue to monitor its movement toward the state line between Nevada and California.

An evacuation centre has been established at the Reno-Sparks Convention Center, located at 4590 South Virginia Street, Reno. The Evelyn Mount Northeast Community Center, which initially served as an evacuation site, quickly reached maximum capacity, prompting the establishment of the secondary shelter at the convention center. Small animals can be taken to Washoe County Regional Animal Services on Longley Lane, while no evacuation centre is currently available for large animals.

The blaze has severely disrupted regional infrastructure, causing widespread power outages that impacted tens of thousands of utility customers across the US state. Emergency de-energization of transmission lines by NV Energy cut electricity to more than 37,000 customers in the Truckee and North Lake Tahoe region. The rapid advancement of the fire also forced the temporary closure of the ER at North Valleys, where healthcare workers scrambled to safely transfer patients to alternative regional facilities.

Significant resources have been mobilised to fight the fire, including air tankers and helicopters. Requests for Cal Fire support have been initiated, and “substantial resources” have been diverted from the nearly-contained Bug Fire to assist with the Hawk Fire. The Bug Fire, located just north of the Hawk Fire, was 94% contained as of Friday, while the nearby Stallion Fire was 98% contained as of Friday. Weather conditions remain challenging, with a Red Flag Warning extending across northern Washoe County toward the California and Oregon borders, increasing the risk of rapid fire growth and spot fires.

UK, Australia, Canada Lead 28 Nations in Condemning Israel Over Gaza Aid Killings Probe Closure

UK, Australia, Canada Lead 28 Nations in Condemning Israel Over Gaza Aid Killings Probe Closure

The United Kingdom, Australia, and Canada have condemned Israel’s decision to close a criminal investigation into the 2024 killing of seven World Central Kitchen (WCK) aid workers in Gaza, calling the move “shameful” and “both too little, and too late.” The announcement came on World Humanitarian Day, August 19, 2026, a timing the three governments described as “particularly egregious.”

The Israeli military announced on August 19 that it would not pursue criminal proceedings into the April 1, 2024 strike on the WCK convoy, saying there was no reasonable suspicion of criminal misconduct. The attack killed seven humanitarian workers who were delivering food to civilians in Gaza. The victims included Australian aid worker Zomi Frankcom, three British security personnel, a dual Canadian-US citizen Jacob Flickinger, Polish national Damian Sobol, and Palestinian Saifeddin Issam Ayad Abutaha. The deadly strike occurred despite the convoy having coordinated its route with the Israeli military, and the vehicles were clearly marked with the WCK logo.

In a joint statement issued on August 21, the foreign ministries of the three countries said they had spent more than two years pressing Israel to conduct a swift and thorough investigation into the attack and hold those responsible to account. The governments noted that at the time, the Israel Defense Forces had described the incident as a serious mistake and failure, and that in the more than two years since, they had been pressing for Israel to swiftly and thoroughly consider the case and hold those responsible to account. The statement said the decision to close the case without further explanation was “shameful” and that announcing it on World Humanitarian Day, while the world honoured the courage and sacrifice of humanitarians, was particularly egregious. The governments stressed that the World Central Kitchen attack was not an isolated incident, arguing that the lack of accountability extended to numerous other incidents involving humanitarian workers in Gaza, noting that despite a fragile ceasefire, Gaza remains the deadliest place to deliver aid, with 186 humanitarian workers killed in 2025.

Australian Foreign Minister Penny Wong separately expressed outrage at the decision, stating that the Israeli military’s response fell short of the standards of accountability Australia expected following the killing of Australian aid worker Zomi Frankcom and six other WCK workers. Wong summoned Israel’s ambassador to Australia, Hillel Newman, to express her concerns and later acknowledged that relations between Australia and Israel were at a “difficult time.” She said the government had learned of Israel’s decision moments before it was announced on World Humanitarian Day, which she described as “especially insulting to Zomi’s loved ones, humanitarians and all Australians.” The foreign minister said key questions remained unanswered, including why two further strikes followed the initial attack, each two minutes apart, why the strikes occurred in a humanitarian “fire control” zone, and Israel’s repeated refusals to hand over audio evidence of the attack. Wong stated that Australia did not have confidence in the IDF’s Military Advocate-General’s process given the many unanswered questions.

Frankcom’s family expressed deep disappointment and called on the Australian government to pursue all available legal avenues for an independent and credible investigation. Her brother, Josh Frankcom, said Israel’s decision was “simply not good enough.” The family has been vocal in demanding accountability for Zomi’s death, and they have questioned why the Israeli military has not provided a satisfactory explanation for the attack.

Israeli Ambassador to Australia Hillel Newman defended the military investigation, saying it was thorough and that the findings should not be attacked if they were not suitable to one’s political agenda. He said the IDF conceded serious failures had led soldiers to mistakenly believe a Hamas fighter was travelling with the convoy, but concluded there was no criminal intent. Newman said Israel was open to discussing reparations for Frankcom’s family if a formal request was lodged, but he stopped short of offering a formal apology, saying doing so could have legal ramifications. The IDF’s decision came alongside announcements that it would open criminal investigations into two other high-profile Gaza incidents: the killing of six-year-old Hind Rajab and six family members in January 2024, and the killing of 15 rescue workers in a Rafah convoy in March 2024. The United Nations has accused Israel of failing to provide adequate accountability for civilian deaths in Gaza, and the latest decision is likely to deepen international isolation for Israel.

North Korea Fires 10+ Missiles Hours After Trump Signals Fresh Kim Summit

North Korea Fires 10+ Missiles Hours After Trump Signals Fresh Kim Summit

North Korea Fires 10+ Missiles Hours After Trump Signals Fresh Kim Summit

North Korea launched more than 10 short-range ballistic missiles toward the East Sea on Thursday, just hours after President Donald Trump publicly declared his intention to meet with North Korean leader Kim Jong Un later this year. The provocative test represents a blunt rejection of Trump’s diplomatic overtures and comes despite his recent order to scale back joint US-South Korean military drills. The launch was detected around 5:00 p.m. local time from the Pyongyang area. According to South Korea’s Joint Chiefs of Staff, the missiles traveled approximately 300 kilometers before landing in the sea, with detailed specifications still under analysis by US and South Korean intelligence. This marks the 12th missile test by Pyongyang this year and comes only eight days after the previous launch.

The missile salvo directly follows a series of conciliatory gestures from Washington. On Monday, Trump posted on social media that he had ordered the Pentagon to “substantially reduce” joint military exercises with South Korea, citing what he described as his “very good relationship” with Kim Jong Un. The following day, Trump told reporters that Kim had responded to his “dialogue” offer, though he declined to share specifics. The Ulchi Freedom Shield (UFS) exercises, originally scheduled to run for 11 days, were abruptly shortened to just 5 days following Trump’s directive. The Pentagon said the reduced drills would cause “no degradation to US training objectives.” Reports indicate Trump is privately pushing aides to arrange a meeting with Kim as early as this fall, potentially during an Asia trip scheduled for November 2026 for the APEC summit in Shenzhen.

Despite these overtures, North Korea responded with defiance. Kim Yo Jong, the powerful sister of Kim Jong Un and a senior Workers’ Party official, issued a statement dismissing the reduction in US-South Korean drills as “not even worth commenting on” and “completely uninteresting.” “Reducing the scale or duration of the exercises does not change their fundamentally provocative and aggressive nature,” Kim Yo Jong said. She emphasized that the joint exercises are “still underway,” calling them “an unmistakable expression of hostility toward North Korea.” As for the communication between the North Korean and American leaders mentioned by President Trump, Kim Yo Jong clearly drew the line by saying she has “absolutely no knowledge of it.” She added, however, that “relations between the two leaders remain excellent,” saying this is “well known to the world and hardly surprising.” Her statement, issued just hours before the missile launch, effectively signaled that Pyongyang would not be swayed by US diplomatic gestures alone.

Analysts view the launch as a calculated act of defiance with multiple strategic objectives. The test occurred just before the shortened UFS exercises were scheduled to conclude, suggesting frustration that the drills were still ongoing despite the reduction. North Korea has previously used similar provocations during joint US-South Korean exercises, viewing them as preparation for invasion. Trump, who held an unprecedented series of summits with Kim in 2018 and 2019, has since referred to North Korea repeatedly as a “nuclear power,” although his administration continues to call for denuclearisation. Trump told reporters on Wednesday that North Korea possesses 57 “very powerful” nuclear weapons, a specific figure he has cited for the first time regarding the North’s nuclear stockpile. South Korean estimates put the country’s nuclear arsenal at between 80 and 120 weapons. Trump’s renewed engagement with Kim has raised concerns among some US allies in Asia and sparked speculation that he may be seeking a diplomatic breakthrough as efforts to resolve the Iran conflict encounter difficulties.

South Korea’s presidential office convened an emergency national security meeting immediately following the launch, condemning the act as a grave violation of UN Security Council resolutions. The office stressed the need to maintain a “thorough readiness posture” and urged Pyongyang to halt such provocations. South Korean, US, and Japanese authorities are sharing intelligence and maintaining heightened readiness, with the South Korean military emphasizing its ability to “overwhelmingly respond to any provocation.” The United States currently maintains approximately 28,500 troops in South Korea, a legacy of the 1950-53 Korean War that ended with an armistice rather than a formal peace agreement. South Korean Defence Minister Ahn Gyu-back said Seoul remained opposed to officially recognising the North as a nuclear-weapon state. Asked whether Washington had “given up” on North Korea’s denuclearisation, Ahn said he did not believe so. President Lee Jae Myung, who has advocated stronger domestic defence capabilities to lessen Seoul’s dependence on Washington, said he would “do his utmost” to support Trump’s peacemaking efforts with the North.
