 A baseline mission scenario to asteroid 1999 JU3 included a launch with a Soyuz-type launcher of a Mother Spacecraft (MSC) possibly carrying a lander, a sampling device, a re-entry capsule and scientific payloads.The lander would perform a soft landing, anchor to the asteroid surface, and make various "in situ" measurements of surface/subsurface materials near the sampling site.Samples would be collected with either one or complementary techniques.
