SUMMARY:The perils of planetary geology: why no one should ever complain a
 bout mapping in Britain and Ireland - Jack Wright (Open University)

DESCRIPTION:Geology rocks\, but there are times when it can be a bit of a 
 drag\, like mapping in the wind and rain.  What if you could do geology wh
 ere rain doesn’t fall and the wind never blows\, such as the Moon or Mer
 cury?  What then?\n\nWith only a few notable exceptions\, geologists have 
 no field observations of the planetary bodies in the solar system and beyo
 nd.  We must rely on remote sensing techniques and our understanding of th
 e Earth to study these fascinating and varied bodies.  In this scenario\, 
 nobody is likely to get wet and chilly\, but maybe the long list of health
  warnings that comes with planetary geology will make you break out in a c
 old sweat after all.\n\nTechnical problems include yawning data gaps\, tan
 talising image resolutions\, unhelpful illumination that makes mountains d
 isappear\, instruments going blind and the ultimate hitch of mission failu
 res.  But there are geological and philosophical problems too\, such as ho
 rrific sampling biases\, the difficulty in dating planetary surfaces\, the
  unfamiliar landforms on extraterrestrial bodies and the ‘baggage’ tha
 t comes into space with us from Earth.\n\nIn this talk\, I will outline ho
 w planetary scientists overcome these issues with a focus on my own PhD wo
 rk on Mercury\, with extra examples from throughout the solar system.
