In order to help further these objectives, and to mark the 40th anniversary of human spaceflight, I organised a one-day symposium on The Scientific Case for Human Spaceflight as part of the 2001 UK National Astronomy Meeting. This was followed by Royal Astronomical Society Specialist Discussion meetings on the Scientific Case for Human Space Exploration on 10 December 2004, and Astronomy from the Moon on 14 December 2007.
In 2003 I was a member of the Human Spaceflight Vision Group (HSVG), established by the European Space Agency (ESA) to advise on future human space projects. The HSVG reported in December 2003 and recommended that ESA participate in sending astronauts back to the Moon, for a range of scientific, cultural, political and economic reasons. I was primarily responsible for collating the scientific case, which has been published in full as ``The scientific case for renewed human activities on the Moon'', Space Policy, 20, 91-97, (2004). In 2007 I was a member of the UK Space Exploration Working Group, which recommended increased UK involvement in space exploration within the developing Global Exploration Strategy.
A more detailed statement of my views on the scientific and cultural case for human space exploration can be found on the Case for Space webpage that I maintain.
