NASA is accelerating plans to put a nuclear reactor on the moon, and they claim it could happen by 2030.
In a directive – a written or oral instruction issued by the US government – to NASAstaff earlier this month, Sean Duffy, US transport secretary and the new interim administrator of the space agency, said it should be ready to launch a 100 kilowatt nuclear reactor in five years.
Plans to get a reactor on the lunar surface are not new. The NASA website states the space agency is working on the Fission Surface Power Project to create a system capable of generating at least 40 kilowatts of power – but that is less than half of what Mr Duffy has now proposed.
He also stressed the importance of America’s space agency deploying the technology before China and Russia.
“To properly advance this critical technology, to be able to support a future lunar economy, high power energy generation on Mars, and to strengthen our national security in space, it is imperative the agency move quickly,” the directive, which was first reported on by Politico, states.

A nuclear reactor on the moon would be considered a key step towards building a permanent base for humans to live on the lunar surface.
But Mr Duffy warned that the first country to deploy a reactor “could potentially declare a keep-out zone” which he said could significantly inhibit NASA’s Artemis mission – the lunar exploration programme which aims to land astronauts back on the moon in 2027.
When quizzed about the plan on 5 August, he told reporters: “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.”
Why use a nuclear reactor?
Unlike solar power, which is used on the International Space Station, a small nuclear reactor can operate continuously, Dr Sungwoo Lim, a senior lecturer in space applications, exploration and instrumentation at the University of Surrey told Sky News.
This is critical for infrastructure on the moon, which spends two weeks in complete darkness as it slowly orbits the Earth.
Nuclear reactors therefore diminish the need for sunlight, and can be used to power life support, communications and other critical science instruments, even in darkness.

“In practice, this means astronauts could use a reactor to establish sustainable bases and extend exploration to places where solar energy is impractical,” Dr Lim adds, including in the moon’s permanently shadowed region, where scientists believe ice water exists.
Professor Mike Fitzpatrick, an expert in nuclear technology at Coventry University, adds that the proposal of a 100 kilowatt nuclear reactor, is relatively small compared to most that are built on Earth.
To put it in real terms, it takes around three kilowatts to power the kettle in your home.
But Prof Fitzpatrick says a smaller reactor could pose as “demonstrator technology”, something small and compact that makes it easier to transport it to the moon.
“Then you can have a whole array of them,” he says.
So, what’s the catch?
While scientists agree that nuclear energy seems like the necessary way to make progress on the moon, Prof Fitzpatrick says questions still remain about safety.
“Shipping the fuel to the moon is relatively safe, because at that point it is not particularly toxic, it is the highly reactive fission products that become the issue,” he says.
“What’s going to be the strategy for long-term storage and disposal on the moon after these plants have operated for certain periods of time? The sooner those conversations are had, and you have international consensus, the less likely it is you’ll get future friction.”

Dr Lim also questioned Mr Duffy’s timescale of 2030, saying meeting the target depends heavily on the space agency’s budget.
NASA’s future funding is currently unknown after Donald Trump’s 2026 budget request sought a cut of $6bn (£4.5bn) and the termination of dozens of science programs and missions.
Over 2,000 agency employees are also set to voluntarily leave NASA in the coming months under the Trump administration’s “deferred resignation” programme.
Is this the new space race?
Last year, Russia’s space agency Roscosmos said it was planning to build a lunar nuclear reactor alongside China’s National Space Administration by 2035, in order to power the International Lunar Research Station (ILRS).
The collaboration was never formally announced by China but the joint plan was included in a presentation by Chinese officials in April this year, which outlined the 2028 Chang’e-8 lunar mission which aims to lay the groundwork for the ILRS.
“Duffy explicitly described it as a competition,” says Dr Lim, adding that the move towards lunar exploration signals a renewed moon or space race among major parties like China, Russia, India and the US to claim strategic lunar territory and technology.
However, Rossana Deplano a professor of international space law at the University of Leicester, says there is a lot of misunderstanding around “keep out” or safety zones, which Mr Duffy’s directive mentions.
“Safety zones are explicitly recognised in the Artemis Accords,” she says.
“They are a notification and consultation zone to be declared in advance in order to avoid harmful interference.
“They must be temporary in nature and do not establish state jurisdiction, e.g. they cannot be enforced.”
Settlements are illegal under international law and have been condemned by the UN. They are, however, authorised by the Israeli government.
As well as official, government-approved settlements, there are also Israeli outposts.

Israeli settlers attack Palestinian villages
These are established without government approval and are considered illegal by Israeli authorities. But reports suggest the government often turns a blind eye to their creation.
Israel began building settlements shortly after the 1967 Six-Day War.
The Etzion Bloc in Hebron, which was established that year, now houses around 40,000 people.
According to the Israel Policy Forum, the settlement programme is intended to protect Israel’s security, with settlers acting as the first line of defence “against an invasion”.
The Israeli public appears divided on the effectiveness of the settlements, however.

A 2024 Pew Research Centre poll found that 40% of Israelis believe settlements help Israeli security, 35% say they hurt it, and 21% think they make no difference.
Why are they controversial?
Israeli settlements are built on land that is internationally recognised as Palestinian territory.

The activists trying to stop Israeli settlers
Sky News has spoken to multiple Palestinians who say they were forced out of their homes by Israeli settlers, despite having lived there for generations.
“They gradually invade the community and expand. The goal is to terrorise people, to make them flee,” Rachel Abramovitz, a member of the group Looking The Occupation In The Eye, told Sky News in May.
Settlers who have spoken to Sky News say they have a holy right to occupy the land.
American-born Israeli settler Daniel Winston told Sky’s chief correspondent Stuart Ramsay: “God’s real, and he wrote the Bible, and the Bible says, ‘I made this land, and I want you to be here’.”
Settlers make up around 5% of Israel’s population and 15% of the West Bank’s population, according to data from Peace Now.
How have things escalated since 7 October 2023?
Since the Hamas-led attacks on 7 October 2023 and Israel’s subsequent military bombardment of Gaza, more than 100 Israeli outposts have been established, according to Peace Now.
In May, Prime Minister Benjamin Netanyahu’s government approved 22 new settlements, including the legalisation of outposts that had previously been built without authorisation.
Settler violence against Palestinians has also increased, according to the UN, with an average of 118 incidents each month – up from 108 in 2023, which was already a record year.
The UN’s latest report on Israeli settlements notes that in October 2024, there were 162 settler attacks on Palestinian olive harvesters, many of them in the presence of IDF soldiers.
Of the 174 settler violence incidents studied by the UN, 109 were not reported to Israeli authorities.
Most Palestinian victims said they didn’t report the attacks due to a lack of trust in the Israeli system; some said they feared retaliation by settlers or the authorities if they did.
Madonna has urged the Pope to go to Gaza and “bring your light” to the children there.
In a plea shared across her social media channels, the pop star told the pontiff he is “the only one of us who cannot be denied entry” and that “there is no more time”.
“Politics cannot affect change,” wrote the queen of pop, who was raised Catholic.
“Only consciousness can. Therefore I am reaching out to a Man of God.”
The Like A Prayer singer told her social media followers her son Rocco’s birthday prompted her post.
“I feel the best gift I can give to him as a mother – is to ask everyone to do what they can to help save the innocent children caught in the crossfire in Gaza.
“I am not pointing fingers, placing blame or taking sides. Everyone is suffering. Including the mothers of the hostages. I pray that they are released as well.”

Pope Leo has been outspoken about the crisis in Gaza since his inauguration, calling for an end to the “barbarity of war”.
“I appeal to the international community to observe humanitarian law and respect the obligation to protect civilians as well as the prohibition of collective punishment, of indiscriminate use of force and forced displacement of the population,” he said in July.

Gaza: ‘This is a man-made crisis’
WHO chief thanks Madonna
Every child under the age of five in Gaza is now at risk of acute malnutrition, according to UNICEF – “a condition that didn’t exist in Gaza just 20 months ago”.
At the end of May, the NGO reported that more than 50,000 children had been killed or injured since October 2023.
World Health Organisation director general Tedros Adhanom Ghebreyesus thanked Madonna for her post, saying: “humanity and peace must prevail”.
“Thank you, Madonna, for your compassion, solidarity and commitment to care for everyone caught in the Gaza crisis, especially the children. This is greatly needed,” he wrote on X.
Sky News has obtained shocking CCTV from inside the main hospital in the city of Sweida in southern Syria – where our team found more than 90 corpses laid out in the grounds following a week of intense fighting.
Warning this article shows images of a shooting
The CCTV images show men in army fatigues shooting dead a volunteer dressed in medical scrubs at point-blank range while a crowd of other terrified health workers are held at gunpoint with their hands in the air.
The mainly Druze city of Sweida was the scene of nearly a week of violent clashes, looting and executions last month which plunged the new authorities into their worst crisis since the toppling of the country’s former dictator Bashar al Assad.
The new Syrian government troops were accused of partaking in the atrocities they were sent in to quell between the Druze minority and the Arab Bedouin minority groups.
The government troops were forced to withdraw when Israeli jets entered the fray, saying they were protecting the Druze minority and bombed army targets in Sweida and the capital Damascus.

Days of bloodletting ensued, with multiple Arab tribes, Druze militia and armed gangs engaging in pitched battles and looting before a ceasefire was agreed.

The government troops then set up checkpoints and barricades encircling Sweida to prevent the Arab tribes re-entering.
The extrajudicial killing captured on CCTV inside the Sweida hospital is corroborated by eyewitnesses we spoke to who were among the group, as well as other medics in the hospital and a number of survivors and patients.

The CCTV is date- and time-stamped as mid-afternoon on 16 July and the different camera angles show the men (who tell the hospital workers they are government troops) marauding through the hospital; and in at least one case, smashing the CCTV cameras with the butt of a rifle.
One of the nurses present, who requested anonymity, told us: “They told us if we talked about the shooting or showed any film, we’d be killed too. I thought I was going to die.”
Dr Obeida Abu Fakher, a doctor who was in the operating section at the time, told us: “They told us they were the new Syrian army and interior police. We cannot have peace with these people. They are terrorists.”
Multiple patients and survivors told us when we visited the hospital last month that government troops had participated in the horror which swept through Sweida for days but this is the first visual evidence that some took part in atrocities inside the main hospital.
In other images, one of the men can be seen smashing the CCTV camera with the butt of his rifle – and another is wearing a black sweater which appears to be the uniform associated with the country’s interior security.
One survivor calling himself Mustafa Sehnawi, an American citizen from New Jersey, told us: “It’s the government who sent those troops, it’s the government of Syria who killed those people… we need help.”

The government responded with a statement from the interior ministry saying they would be investigating the incident which they “denounced and condemned” in the strongest terms.
The statement went on to promise all those involved would be “held accountable” and punished.
The new Syrian president Ahmed al Sharaa is due to attend the United Nations General Assembly next month in New York – the first time a Syrian leader has attended since 1967 – and what happened in Sweida is certain to be among the urgent topics of discussion.
