Executive Summary of the mission study by OHB-System AG (Reference: MPL-OHB-TN-014).

This executive summary presents the results of the Marco Polo study performed under ESA contract by the industrial team led by OHB-System AG, for an ESA-defined scenario. Possible collaboration schemes associated with this scenario are not addressed here. The results presented address the mission and system design of the ESA space element of the Marco Polo mission including the analysis of critical technologies required for this ambitious mission.
The industrial team was led by OHB-System AG and included the following partners:

• GMV S.A. - focussing on mission analysis and GNC technologies
• Sener S.A. - focussing on landing and sample acquisition technologies
• Aero Sekur S.p.A. - focussing on high speed re-entry technologies
• QinetiQ Ltd - providing consultancy in the area of electric propulsion

SPICA is a JAXA led astronomical mission. The ESA contribution to the SPICA mission, mainly entailing the provision of the cryogenic telescope assembly, is a M-class candidate in the Cosmic Vision 2015-2025 Plan. This document provides a summary of the work performed between August 2008 and September 2009 as part of the SPICA assessment phase study.

In the frame of ESA Cosmic Vision assessment study, Thales propose a 3.5m diameter Ritchey-Chretien telescope in HB-Cesic ceramics. The evaluation of its performances demonstrate that the proposed design perfectly fulfils the mission requirements. The objective of this paper is to provide to the reader an overview of the telescope design and performances of the HB-Cesic SPICA Telescope. The development plan is also addressed. It has been established to minimize risks and schedule. The last point is a sensitivity analysis to pupil diameter reduction: an interesting way to further reduce development schedule.

• to assess the feasibility of the proposed mission
• to prepare for the future competitive industrial assessment studies by identifying critical issues that need addressing at higher priority
• to provide the building blocks and feed-back for further interaction with the science team for formulation of feasible mission goals.

To this end, the CDF study established bottom-up designs for three elements: a montgolfière, a long-lived lander (powered by an ASRG), and a minimum sized small lander of limited lifetime (powered by battery).

This report describes the design of the chosen baseline after the first technical iteration and incuding an updated mission profile providing enhanced mass capability of the delivery of the in situ elements, after the addition of a solar electric propulsion stage of the NASA orbiter.

This report is the result of an independent ESA internal assessment study.

JEO is the NASA Element of the Europa Jupiter System Mission (EJSM).

The objective of this study, to assess the science merit, technical risk and qualitative assessment of relative cost of alternative architectural implementations as applied to a first dedicated mission to Europa, was accomplished by 1) reviewing results from previous and current studies and 2) examining alternative architectural options relative to the science objectives defined by the 2007 EE SDT. This report summarizes a number of Europa mission and system concepts studied over the last decade as well as the results from assessing alternative architectural options in light of current science requirements.

The Europa Jupiter System Mission (EJSM) is a joint endeavour by ESA and NASA.

This Joint Summary Report (JSR) is intended to provide a high-level description of the following: the science rationale and goals; the mission concept; the NASA and ESA responsibilities and interdependencies; the role of other space agencies; and the costs, schedule, and management approach. The JSR also describes the membership and roles of the JSDT and the engineering study teams that supported them and provides a guide to the extensive documentation that has been developed for the mission concept.
