The true power of the solar wind
(Vienna University of Technology) The planets and moons of our solar system are continuously being bombarded by particles from the sun. On the Moon or on Mercury, the uppermost layer of rock is gradually eroded by the impact of sun particles. New results show that previous models of this process are incomplete. The effects of solar wind bombardment are much more drastic than previously thought. These findings are important for the ESA mission BepiColombo, Europe's first Mercury mission.
