Combining two Orions provides just enough propellant, supplies, and living space to reach the easiest asteroids. The twin spacecraft also provide redundancy in the event of a failure on one spacecraft. The space ...

X-ray fluorescence from rough rocky surfaces of asteroids
... X-ray fluorescence (XRF) from orbit is a frequently-used technique to determine the elemental composition of atmosphereless planetary bodies. So far, XRF observations have been conducted for asteroids by the Near-Earth Asteroid Rendezvous Shoemaker mission at (433) Eros [1] and the Hayabusa mission ...

Hayabusa
Hayabusa (はやぶさ, literally ""Peregrine Falcon"") was an unmanned spacecraft developed by the Japan Aerospace Exploration Agency (JAXA) to return a sample of material from a small near-Earth asteroid named 25143 Itokawa to Earth for further analysis.Hayabusa, formerly known as MUSES-C for Mu Space Engineering Spacecraft C, was launched on 9 May 2003 and rendezvoused with Itokawa in mid-September 2005. After arriving at Itokawa, Hayabusa studied the asteroid's shape, spin, topography, colour, composition, density, and history. In November 2005, it landed on the asteroid and collected samples in the form of tiny grains of asteroidal material, which were returned to Earth aboard the spacecraft on 13 June 2010.The spacecraft also carried a detachable minilander, MINERVA, which failed to reach the surface.
