The White House says Donald Trump is the only person who knows his plans for Iran, after his threat that a ‘whole civilisation will die’ if Tehran doesn't do a deal to end the war. The President's latest deadline for Iran to reopen the Strait of Hormuz or face the destruction of key infrastructure, expires within hours.

The Artemis II astronauts are bound for a return to Earth after conducting a historic lunar fly-by and witnessing a total solar eclipse from their spacecraft.

The spacecraft reached its maximum distance from Earth - 252,756 miles (406,771km), the furthest distance humans have travelled into space. We'll hear from NASA's Head of Science.

Also in the programme: Multiple reports indicate new US strikes on Kharg Island in the Gulf as President Trump posts that "a whole civilisation will die tonight" unless a deal is reached; US vice-president JD Vance visits Hungary ahead of elections; Cambodia says it's cracking down on scammers; and Kanye West has been blocked from travelling to the UK over anti-Semitic comments.

Four astronauts have taken humanity deeper into space than ever before, breaking a record set in 1970. We hear from space expert Dr Kevin Fong as well as the singer from Young & Sick. His song was played to wake up the Artemis crew in space.

Also on the programme: President Trump repeats his deadline for Iran to agree to a deal with the United States; and the discovery of Yiddish songs performed during the Holocaust.

Iran says the intelligence chief of the Islamic Revolutionary Guard Corps, Majid Khademi, was killed in a strike on Monday morning; Israel later claimed responsibility for the attack.

As US-Israeli strikes on Iran continue, Iranian people tell the BBC that they're afraid of the latest ultimatum from President Trump.

Also in the programme: NASA's Artemis II mission has now entered the lunar "sphere of influence"; how Northern Ireland has become a world leader in support for mothers who've miscarried; and the icy world of curling hits a hot streak as it starts a professional league.

Trump uses expletives to warn of attacks on Iranian infrastructure unless the Strait of Hormuz is opened to shipping. We hear from our Chief International Correspondent Lyse Doucet, and ask where this threatened escalation in the war leaves America's allies in the Gulf.

Also in the programme: Hungary and Serbia say they've foiled a plot to blow up a pipeline, but is it a 'false flag' operation ahead of the upcoming Hungarian election? And the American museum curator in her seventies who has become a social media star.

In an operation involving hundreds of troops and dozens of aircraft, the US military have rescued the American airman who went missing in southern Iran after an F-15 fighter jet was shot down on Friday. President Trump said the colonel was injured but will be fine.

President Trump has threatened to unleash hell on Iran in forty- eight hours if its leaders don't make a deal or open up the Strait of Hormuz. Iran has virtually closed off the strait, through which twenty percent of the world's oil is exported. The Iranian military has credited new air defence systems with the reported downing of two American military planes on Friday. A crew member from one of the aircraft is still missing.

Also in the programme: Teachers' union in the UK warns of 'masculinity crisis brewing' in schools; we look at how the war in Iran is making petrol and diesel increasingly expensive in Australia; and we hear from Ed Dwight, the first Black man on the US Space program.

The US pilot reportedly ejected and has been rescued, despite an Iranian bounty offered for his capture. Another crew member may still be missing in Iran. We hear the latest, and discuss the perils of rescue missions in hostile territory with former US Marine Corps Special Operations specialist Jonathan Hackett.

President Donald Trump says the US "hasn't even started destroying what's left in Iran", adding that Iranian bridges are "next, then electric power plants." Mr. Trump has also signalled his openness to diplomacy in an effort to end the war. Iran has launched fresh strikes on Israel and Gulf nations, after the US and Israel stepped up their attacks on Iran's infrastructure.

Also in the programme: an update on the progress of the Artemis II moon mission; and the unusual way octopuses have sex.
