Tim Peake, Al Worden, and Helen Sharman

A stand-out moment at the event was the astronaut panel. Helen Sharman, the first Briton in space, was aboard the Soyuz TM-12 mission launched on 18 May, 1991. Tim Peake, the first British ESA astronaut, was the most experienced on the panel as a former International Space Station (ISS) crew member. Al Worden was a Command Module Pilot for Apollo 15, and is one of the few astronauts that have flown to the Moon. He spoke enthusiastically about seeing the Earth and Moon together for the first time in the first deep-space space walk. The team discussed their favourite moments of their missions: Sharman remembered fondly the feeling of weightlessness, her experiments and emphasised the importance of the team you go with. Both Peake and Worden spoke about their desire to go to Mars.
