The paper presents how the world's first asteroid lander Hayabusa moved around on the surface of its destination target Itokawa last November. Not enough information is available to determine the trace for the motion retrieved through the telemetry data. The combination of the altitude, the distance from the Earth and the terrain vertical direction obtained by the Laser Range Finder enables the spacecraft position to be estimated. The paper also gives the gravity acceleration at the very low altitude directly measured from that information, as well as the surface stiffness information. They are the first results associated with the Hayabusa descent and landing.
