\nSeen on a microscopic support, this sharp-edged grain of rock is an extraterrestrial object – a tiny sample from the Itokawa<\/a> asteroid, retrieved by Japan’s Hayabusa<\/a> mission and now being tested by ESA researchers.\n<\/p>\n

\nJapan’s Hayabusa spacecraft was the world’s first mission to retrieve samples from the surface of an asteroid and return them to Earth. Beset by many problems, after a seven-year, six-billion-km odyssey Hayabusa returned around 1 500 precious asteroid grains to Earth.\n<\/p>\n

\nExtremely precious, these Hayabusa grains have become the focus of scientific study around the world – and three of them are currently here, at ESA’s ESTEC<\/a> technical centre in the Netherlands.\n<\/p>\n

\nResearcher Fabrice Cipriani is leading research into their static charging properties, to understand the consequences for the surface environments of asteroids.\n<\/p>\n
