SUMMARY:The geology of Mercury and the BepiColombo mission - Professor Dav
 id Rothery

CONTACT:Hannah Sanderson
DESCRIPTION:Mercury is a weird planet. It has relatively little rock surro
 unding its iron core\, but this rock is surprisingly rich in volatile elem
 ents. Almost all the crust is volcanic lava flows more than 3 billion year
 s old\, but explosive eruptions (which must be driven by volatiles expandi
 ng violently as gas) persisted into the last billion years. Present-day vo
 latile loss leaves ‘moth-eaten’ patches called ‘hollows’ where 10-
 20m of surface material has been removed\, by a gentle process possibly ak
 in to sublimation.\nThe BepiColombo spacecraft\, launched in October\, wil
 l begin science in Mercury orbit in 2026. It should be able to map and ide
 ntify the volatiles\, as well as imaging Mercury in more detail than ever 
 before.\n\nThe talk will be followed by refreshments outside the lecture t
 heatre.\nThe talk will be at 7:30pm at the usual location of Wolfson lectu
 re theatre in the Department of Chemistry. The entrance is the opposite si
 de of the building to Bristol-Myers-Squibb Lecture theatre and is opposite
  the car park- shown by the red arrow on the map. "https://map.cam.ac.uk/D
