The American billionaire Jared Isaacman has led the first-ever privately funded space-walk - and not just for fun, as the mission is testing innovative spacesuits designed to protect humans on Mars.

Also in the programme: we hear from UNRWA, the UN agency for Palestinian refugees, after six of its staff were among 18 killed in an Israeli air strike on one of its schools in Gaza that was being used as a shelter; and after the rock star Bon Jovi talks down a suicidal woman, what is the best way to persuade someone not to take their own life?
