“…For this reason, the development of surface landers remains an important option for in situ life-signal measurements at Europa. Several lander missions have been considered during the past decade, and an advanced design has already been proposed and continues to be improved Zelenyi et al, 2011). A lander would carry more payload instruments and have a significantly longer lifetime when compared to smaller devices such as penetrators.…”

The Europa Jupiter System Mission (EJSM) is the major Outer Planet Flagship Mission in preparation by NASA. Although well designed, the current EJSM concept may present problematic issues as a Flagship Mission for a long-term exploration program that will occur over the course of decades. For this reason, the present work reviews the current EJSM concept and presents a new strategy for the exploration of Europa. In this concept, the EJSM is reorganized to comprise three independent missions focused on Europa. The missions are split according to scientific goals, which together will give a complete understanding of the potential habitability of Europa, including in situ life's signal measurements. With this alternative strategy, a complete exploration of Europa would be possible in the next decades, even within a politically and economically constrained environment.

Abstract. Based on the suspension structure, this paper develops some methods to describe the change of links and kinematic pairs during the folding process of the suspension. Employing these methods, the increase and decrease of links and pairs, as well as the change of pairs' feature can be demonstrated clearly. An idea is proposed to obtain a large number of folding schemes for the suspension. On the basis of this idea, one mechanism is decomposed into some basic kinematic chains firstly and then these chains (with folding function) are fused to form one complete mechanism. As the application of proposed methods, the suspension, which is shown in this study, is divided into three basic kinematic chains and many reasonable folding schemes for each chain are obtained. Through fusion operation, a number of folding configurations for the rover are achieved. At the end of this paper, we present several generally accepted constrain conditions to compare the obtained schemes, and one folding scheme with the best folded-deployable performance is chosen.

The mathematical modeling results of the simultaneous processes of heat and mass transfer under the conditions of intense phase changes (melting of ice) during the movement of cryobot have been given. The spatial unevenness of the melting rate of ice has been taken into account. It has been established that the rate of passage of the cryobot depends essentially on its temperature. According to the results of the numerical simulation, considerable cooling of the cryobot sheath has been established. The latter is due to the high endothermic effect of melting ice.
