Boeing has called off its first-ever astronaut launch at the final moment after discovering a valve problem in the Atlas V rocket.
The two NASA test pilots had just strapped into Boeing‘s Starliner capsule at Cape Canaveral space station for a flight to the International Space Station on Monday night (US EST) when the countdown stopped – two hours before the planned lift-off.
It was the latest delay for Boeing’s first crew flight, on hold for years because of capsule trouble.
The Atlas V rocket is manufactured by the United Launch Alliance, which includes Boeing and Lockheed Martin.
United Launch Alliance’s chief executive Tory Bruno said the most recent delay may have been caused by an oxygen pressure-relief valve on the upper stage of the rocket that started fluttering open and closed, creating a loud buzz.
The valve may have exceeded its 200,000 lifetime cycles which means it will have to be replaced, pushing the launch into next week, Mr Bruno said.
In an update, NASA said the launch will take place no earlier than Friday.

Mr Bruno said similar valve issues had occurred in previous years on other Atlas rockets launching satellites and these were resolved by turning the valves off and back on.
But the company has stricter flight rules for astronaut flights, prohibiting valve recycling when a crew is on board.

“And so we stayed with the rules and the procedures, and scrubbed as a result,” Mr Bruno said at a news conference.
It meant the two-member crew of NASA astronauts Barry “Butch” Wilmore, 61, and Sunita “Suni” Williams, 58, had to be removed from the capsule by technicians, before they were whisked away from the launch complex to await a second flight attempt when the issue is resolved.

NASA’s commercial crew programme manager Steve Stich added: “We’re taking it one step at a time, and we’re going to launch when we’re ready and fly when it’s safe to do so.”
Starliner’s first test flight without a crew failed to reach the space station in 2019 and Boeing had to repeat the flight. The company then encountered parachute issues and flammable tape.

US President Donald Trump is putting “heavy” pressure on Israeli Prime Minister Benjamin Netanyahu to end the war in Gaza, two sources close to the ceasefire negotiations have told Sky News.
One US source said: “The US pressure on Israel has begun, and tonight it will be heavy.”
A second Middle Eastern diplomatic source agreed that the American pressure on Israel would be intense.

Netanyahu arrived in Washington DC in the early hours of Monday morning and held meetings on Monday with Steve Witkoff, Trump’s Middle East envoy, and Marco Rubio, the secretary of state and national security adviser.
The Israeli prime minister plans to be in Washington until Thursday with meetings on Capitol Hill on Tuesday.
Trump has made clear his desire to bring the Gaza conflict to an end.
However, he has never articulated how a lasting peace, which would satisfy both the Israelis and Palestinians, could be achieved.
His varying comments about ownership of Gaza, moving Palestinians out of the territory and permanent resettlement, have presented a confusing policy.

‘Israel has shifted towards economy of genocide’
Situation for Palestinians worse than ever
Over the coming days, we will see the extent to which Trump demands that Netanyahu accepts the current Gaza ceasefire deal, even if it falls short of Israel’s war aims – the elimination of Hamas.
The strategic objective to permanently remove Hamas seems always to have been impossible. Hamas as an entity was the extreme consequence of the Israeli occupation.
The Palestinians’ challenge has not gone away, and the situation for Palestinians now is worse than it has ever been in Gaza and also the West Bank. It is not clear how Trump plans to square that circle.

‘Some Israeli commanders can decide to do war crimes’
Trump’s oft-repeated desire to “stop the killing” is sincere. Those close to him often emphasise this. He is also looking to cement his legacy as a peacemaker. He genuinely craves the Nobel Peace Prize.
In this context, the complexities of conflicts – in Ukraine or Gaza – are often of secondary importance to the president.
If Netanyahu can be persuaded to end the war, what would he need?
The hostages back – for sure. That would require agreement from Hamas. They would only agree to this if they have guarantees on Gaza’s future and their own future. More circles to square.

Trump 100: We answer your questions
Was White House dinner a key moment?
The Monday night dinner could have been a key moment for the Middle East. Two powerful men in the Blue Room of the White House, deciding the direction of the region.
Will it be seen as the moment the region was remoulded? But to whose benefit?
Trump is a dealmaker with an eye on the prize. But Netanyahu is a political master; they don’t call him “the magician” for nothing.

Trump makes decisions instinctively. He can shift position quickly and often listens to the last person in the room. Right now – that person is Netanyahu.
Gaza is one part of a jigsaw of challenges, which could become opportunities.
Diplomatic normalisation between Israel and the Arab world is a prize for Trump and could genuinely secure him the Nobel Peace Prize.
But without the Gaza piece, the jigsaw is incomplete.
Only one issue remains unresolved in the push to achieve a ceasefire in Gaza, according to Sky sources.
Intense negotiations are taking place in Qatar in parallel with key talks in Washington between US President Donald Trump and Israeli Prime Minister Benjamin Netanyahu.
Two sources with direct knowledge of the negotiations have told Sky News that disagreement between Israel and Hamas remains on the status and presence of the Israel Defence Forces (IDF) inside Gaza.

Gaza ceasefire deal in progress
The two sides have bridged significant differences on several other issues, including the process of delivering humanitarian aid and Hamas’s demand that the US guarantees to ensure Israel doesn’t unilaterally resume the war when the ceasefire expires in 60 days.
On the issue of humanitarian aid, Sky News understands that a third party that neither Hamas nor Israel has control over will be used in areas from which the IDF withdraws.

This means that the controversial Gaza Humanitarian Foundation (GHF) – jointly run by an American organisation and Israel – will not be able to operate anywhere where the IDF is not deployed. It will limit GHF expansion plans.
It is believed the United Nations or other recognised humanitarian organisations will adopt a greater role.
On the issue of a US guarantee to prevent Israel restarting the war, Sky News understands that a message was passed to Hamas by Dr Bishara Bahbah, a Palestinian American who has emerged as a key back channel in the negotiations.

The message appears to have been enough to convince Hamas that President Trump will prevent Israel from restarting the conflict.
However, there is no sense from any of the developments over the course of the past day about what the future of Gaza looks like longer-term.
Final challenge is huge
The last remaining disagreement is, predictably, the trickiest to bridge.
Israel’s central war aim, beyond the return of the hostages, is the total elimination of Hamas as a military and political organisation. The withdrawal of the IDF, partial or total, could allow Hamas to regroup.
One way to overcome this would be to provide wider guarantees of clear deliverable pathways to a viable future for Palestinians.
But there is no sense from the negotiations of any longer-term commitments on this issue.
Two key blocks have been resolved over the past 24 hours but the final challenge is huge.
The conflict in Gaza erupted when Hamas attacked southern Israel in October 2023, killing around 1,200 people and taking 251 hostages, according to Israeli figures. Some 20 hostages are believed to remain alive in Gaza.
Israel has killed more than 57,000 Palestinians, according to Gaza’s Hamas-run health ministry, which does not distinguish between combatants and civilians.
A newly released report led by Israeli legal and gender experts presents detailed evidence alleging “widespread and systematic” sexual violence during the Hamas-led terror attack on 7 October.
Warning: This story contains descriptions of rape and sexual violence
The findings, published by the Dinah Project, argue that these acts amount to conflict-related sexual violence (CRSV), and assert that “Hamas used sexual violence as a tactical weapon of war”.
The report draws on 18 months of investigation and is based on survivor testimonies, eyewitness accounts, and interviews with first responders, morgue personnel and healthcare professionals.
According to the Dinah Project, the documented patterns – such as forced nudity, gang rapes, genital mutilation, and threats of forced marriage – indicate a deliberate and coordinated use of sexual violence by Hamasoperatives during the attack.
Reported incidents span at least six locations, including the Nova music festival, and several kibbutzim in southern Israel.

One section of the report describes victims “found fully or partially naked from the waist down, with their hands tied behind their backs and/or to structures such as trees and poles, and shot”.
At the Nova music festival and surrounding areas, the investigators found “reasonable grounds to believe” that multiple women were raped or gang-raped before being killed.
The report’s findings are consistent with earlier investigations by the United Nations and the International Criminal Court (ICC).
The UN’s Special Representative on Sexual Violence in Conflict previously concluded that there were “reasonable grounds to believe” CRSV took place during the attack.

Significantly, the Dinah Project urges the international community to officially recognise the use of sexual violence by Hamas as a deliberate strategy of war and calls on the United Nations to add Hamas to its list of parties responsible for conflict-related sexual violence.

The nature and scale of sexual violence on 7 October have been a subject of intense controversy, with some accusing parties of weaponising the narrative for political ends.
This report seeks to confront what its authors call “denial, misinformation, and global silence,” and to provide justice for the victims.
Hamas has denied that its fighters have used sexual violence and mistreated female hostages.
