The Engineers: Lunar exploration

Humans are returning to the moon for the first time in over 50 years. The multi-national mission is called Artemis and involves the most powerful rocket and capable spacecraft ever built, a space station in lunar orbit, and a permanent moon-base on the surface. At a special event at the Royal Geographical Society in London, Dr Kevin Fong speaks to three of the world-leading engineers who are making this possible: Howard Hu, Orion programme manager at Nasa, Sara Pastor, chief engineer at the ESA Ihab Gateway, Libby Jackson, head of exploration at the UK Space Agency.
