Event description

Where should humans inhabit next? Apollo Astronaut Al Worden and other space experts will argue their case for settling on the Moon, Mars or travelling beyond. Who will win your vote? 

About the speakers

Al Worden is an American astronaut and engineer who was the Command Module Pilot for the fourth lunar landing mission in 1971, Apollo 15. After his time in space, he was Senior Aerospace Scientist at the NASA Ames Research Center, and then the chief of the Systems Study Division at Ames. Al, (former chairman) is on the Board of Directors of the Astronaut Scholarship Foundation, providing scholarships to exceptional science and engineering students.

Chris Welch is Professor of Space Engineering at the International Space University in Strasbourg, France. Although technically a physicist-turned-engineer, Chris sees himself more as a ‘spaceist’, interested in all aspects of space. Chris is a Vice-President of the International Astronautical Federation, a Fellow of the British Interplanetary Society (BIS), the Royal Aeronautical Society, the Royal Astronomical Society. He is a trustee/board member of the BIS, the Spacelink Learning Foundation, the Arts Catalyst, the Initiative for Interstellar Studies and Vice Chair of the World Space Week Association. Chris has written what he believes to be the first ever paper on the design of extraterrestrial gardens and a poem that he hopes to send to space soon.

Stuart Eves is currently a technical consultant for Vaeros Ltd. He began his career working for the MOD on a variety of satellites, including TopSat, a novel surveillance mission which was the subject of display at the Science Museum following its launch in 2005. From 2004 he was Lead Mission Concepts Engineer at Surrey Satellite Technology Limited, where he helped to initiate the TDS-1 and NovaSAR missions. Stuart is a Fellow of the Royal Astronomical Society, a Council Member of the British Interplanetary Society, and he currently chairs the government/industry Space Information Exchange forum.  In 2017 he published a book entitled "Space Traffic Control" which aims to provide greater resilience for satellite systems.  He conceived the Astro-Pi experiment which was performed by Tim Peake during his time on the ISS, and he also "moonlights" as a GCSE Astronomy teacher.
