Astronaut Helen Sharman is appearing at the Science Museum later this month to talk about her work in space and answer questions from the public.
Sharman was the first British astronaut (and the first woman) to visit the Mir space station, spending a week there in 1991. This event marks the 25th anniversary of her time in space.
She'll be joined by a panel of astronauts from other European countries, with the event led by science writer and Science Museum executive Roger Highfield.
While Sharman's out-of-this-world adventures may seem out of reach for the average Londoner, she was working as a food technologist when she answered a radio advert stating: "Astronaut wanted. No experience necessary." The rest is history.
An Audience With Helen Sharman takes place on 21 May at 10.30am. Earlybird tickets (until 13 May) are £6, after this they're £10/£8/£6.
