A Bit of Asteroid Itokawa

Along with the likes of the Cassini and Rosetta missions we have the history making Hayabusa Mission. The mission actually returned a sample from the asteroid Itokawa and the mission at least for me showcases the resilience of the JAXA mission team (see the section “Changes in mission plan” in the provided link.

The image above was released yesterday 01 Aug 2018 by ESA.

Here’s the caption included in the release:

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

Japan’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.

Extremely 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 technical centre in the Netherlands.

Researcher Fabrice Cipriani is leading research into their static charging properties, to understand the consequences for the surface environments of asteroids.
