American company Intuitive Machines has successfully landed its Odysseus robot near the lunar south pole. The US space agency Nasa had purchased room on it for six scientific instruments. It’s also carrying a box containing 125 small stainless steel balls or mini moons by the American artist Jeff Koons to be left there. There’s now hundreds of tonnes of human objects on the Moon - from old space boots and moon buggies to family photos and a javelin. There are also bags of vomit, urine and poo. It’s becoming a lunar junkyard.

Professor Jill Stuart from the London School of Economics explains the laws governing the moon and BBC journalist Daniel Dadzie tells us what’s up there and what people might take in future.

Also, two years after Russia’s full-scale invasion of Ukraine, what’s life like as a student there? We hear from Vitalii Pashchenko, 21, Arina Stolbtsova, 21 and Yehor Olshevskiy, 17.
