Following on from my talk at Northampton Natural History Society earlier in the week - I've been invited to talk at the British Astronomical Association at the English Heritage Lecture Theatre, London - on April 23rd

(Edit - I will be doing about an hour - but just on Spirit, not Opportunity. My talks are typically 80-90 mins, so I thought it best to cull Opportunity and do that as a seperate talk later in the year, and do a good job on Spirit, which is the better ' story ' - and more classically martian! )
