Abstract

SOCCER, Sample Of Cornet Coma Earth Return, is a joint effort between ISAS and NASA, and its major scientific objective is to collect intact dust samples from the coma of a comet and to bring them back to the Earth. However, in order to realize the SOCCER mission, many scientific and technical requirements and restrictions should be considered. The ISAS/NASA SOCCER Joint Working Group (JWG) has studied technical feasibility for the SOCCER mission to several comet candidates in the 2000 time frame, and the comet Kopff has been chosen as a baseline target with Wild-2 as a backup. The encounter speed is 8.8 km/s for Kopff and 8.7 km/s for Wild-2 respectively. In these cases, however, required C3 and/or AV exceed the launch capability of ISAS's ΔV launch vehicle, and the SOCCER mission should be conducted as a “Geotail-type” international cooperation project using a Delta-II class launch vehicle. In this paper, the results of feasibility study, which include a typical mission scenario and a draft design of the spacecraft system, are presented.
