The Hayabusa-2 mission is currently being studied by JAXA/JSPEC as a sample return mission to the C-type near-Earth asteroid 1999JU3. Hayabusa-2, with launch planned for 2014, would be the immediate successor to the currently flying Hayabusa mission. Originally in the context of the proposed ESA Cosmic Vision M-class mission Marco Polo, but then following an invitation by JAXA/JSPEC, the Institute of Space Systems of the German Aerospace Center (DLR) led a proposal for a separate lander package 'Mascot' (Mobile Asteroid Surface Scout) to be carried on the mission. A feasibility study was subsequently carried out that, upon consultation with the planetary science community, assessed different concepts for the lander that converged to a package with 3 kg of P/L, for a total mass of 10-15 kg. This modest design fulfils the constraints imposed by the Hayabusa-2 mission while still offering excellent science potential. Presently, 'Mascot' enters the preliminary design phase while an Announcement of Opportunity for its payload complement is being prepared.
