Physicist Dr Nicola Fox, who grew up in Hertfordshire, is the new head of science at the US space agency NASA. Only the second woman to hold the post, Dr Fox is a world-renowned expert on the Sun, who'd previously overseen one of the most important missions to study its scientific mysteries. In her new role, Nicola Fox will be responsible for hundreds of NASA projects, including returning humans to the Moon and exploring Mars. Outside of work, she enjoys karaoke... and fashion with a space theme. Mark Coles speaks to Nicola Fox’s friends, family and fellow scientists about how she landed ‘the best job on the planet’.
