The 5th IPPW Workshop (IPPW-5), was held in Bordeaux, France, in June 2007. The conference built on the accomplishments of the four earlier workshops. As with previous workshops, key objectives included fostering international involvement and collaboration in planetary exploration with probes, and engaging the next generation of scientists and engineers in the field of planetary exploration. IPPW-5 continued to focus on outer planet probe missions as well as concepts for probe and aerial platform missions to Mars, Venus, and Titan.

Session 1: Current Outlook

Conveners: S. Hubbard (SETI Institute) J-P. Lebreton (ESA Estec)

An intense focus in both Europe and the United States on plans for solar system exploration during the next two decades.

Session 2: Mission Concept Studies, and Science Drivers of Technology, and Sample Return - Venus and Mars

Conveners: K. Baines (JPL) B. Bienstock (JPL) P. Plotard (EADS)

Since the turn of the century, there has been renewed interest in both Mars and Venus. With NASA's long-lived Mars Exploration Rovers mission and ESA's successful Mars Express and Venus Express Missions, both agencies have developed the required mission concepts and technology to execute these missions. Future exploration of both planets will require substantially more technology development that will enable future missions to achieve the outstanding success of their predecessors.

This session emphasizes the science and technology that will drive future missions planned for next two decades. Science drivers, as expressed in various NASA and ESA planning documents, include the desire to understand planetary origins, evolution, and current processes. Technology drivers focus on new methods of in-situ exploration, including mobile exploration via air-borne rovers or surface explorers, as well as innovative types of instrumentation that could address priority science goals.

Session 3: Entry, Descent and Landing Concepts for Current and Future Missions Beyond Earth

Conveners: M. Wright (NASA Ames) W. Lee (JPL) A. Ball (The Open University)

This session is focused on system-level discussions of currently planned missions, as well as relatively mature mission concept studies and the application of experience from previous missions. The scope covers missions entering the atmospheres of Venus, Mars, Titan and the giant planets, including system design of atmospheric entry, parachute descent and approach to a surface (or balloon inflation).

Session 4: Technology Systems, Electronics, Instruments and Sensors, Communications and Batteries

Conveners: P. Beauchamp (JPL) T. Blancquaert (ESA Estec)

Scientific measurements undertaken from probes are significantly more complex than traditional in situ measurements. High temperatures, pressures, and the attenuation of communication signals limit the penetration depths of probes in the atmospheres of the gas giants. Venus probes must endure even higher temperatures and pressures, while Titan probes must survive and operate at very low temperatures. In the past, extensive thermal control was required to maintain instruments, electronics, and batteries in an earth-like environment for the probes operating at the high and low temperature extremes, adding significantly to the mass and complexity of the system and limiting operational times. Session IV is dedicated to papers describing measurement capabilities and prospects of existing emerging technology systems including electronics, instruments and sensors, communications and battery technologies or strategies that could extend the scientific capabilities of planetary probes operating in extreme environments. Engineering the instruments system within probes, together with instrument miniaturization, can bring improvements in performance and capabilities and this topic will be covered in the session. Also covered are topics describing sample acquisition and sample preparation/manipulation within the instrument system, along with novel instrument components and sub-systems.

Session 5: Mission Concept Studies and Science Drivers of Technology - Giant Planets and Titan

Conveners A. Coustenis (Obs Paris-Meudon) T. Spilker (JPL)

The session focused on science, technology and mission design of probe missions to the outer planets. Papers were solicited on programmatic, technical, scientific, and mission design issues of atmospheric entry and descent exploration of the giant planets and Titan. Science targets includedJupiter, Saturn, Uranus and Neptune, as well as Titan.

Session 6: Entry, Descent, and Landing Technologies for Planetary Missions

Conveners: N. Cheatwood (NASA LaRC) D. Lebleu (Alcatel Alenia)

This session focused on technology development activities which could enhance or enable future planetary missions. The scope included atmospheric Entry, Descent, and Landing for terrestrial (Venus, Earth, Mars, Titan) and gas giant planets. Potential topics included thermal protection systems, deployable aeroshells and decelerators and landing systems.

Session 7: Emerging, Enabling and Extreme Environment Technologies; Cross-Cutting Technologies

Convener: L. Peltz (Boeing)

Probe missions target locations with harsh environments of extreme cold (such as Enceladus and Triton), or extreme hot (such as the surface of Venus), or extreme radiation (such as Europa). Session VII covers the development process and fundamental technologies that enable these new capabilities to operate at extreme cold (below 40 Kelvin), or extreme hot (to 780 Kelvin), or high ambient radiation. What are the technological approaches to producing electronics that can operate at these extreme environments? Topics of interest include: Technologies and circuits of cryogenic-temperature electronics and high-temperature electronics; Radiation tolerance of electronics; Packaging of electronics for extreme environments; Reliability and failure modes of electronic circuits operating in extreme environments; Instrumenting TPS and structures with embedded sensors; and Design approaches and processes for miniaturization of sensing instruments.

Session 8: Earth Entry, Descent and Landing for Sample Return and Crewed Missions

Conveners: J. Arnold (University Affiliated Research Center) B. Foing (ESA Estec)

It is anticipated that solar system exploration during the next decade or two will be characterized by increasing interest in missions involving robotic sample return or crewed Earth Entry, Descent and Landing (EDL) for lunar return. From the perspective of vehicle entry environments, these are challenging missions since the entry interface speeds range from 11 to 14 (plus) km/sec (corresponding to return from the moon and the remote regions of the Solar System, respectively). This session will include papers treating aspects of EDL relevant to such missions involving superorbital Earth re-entry. Since there is much in common for EDL between the robotic sample return missions and NASA's Orion program, contributions from that community are encouraged. Appropriate subject matter includes technology, Earth return EDL capsule design, Earth entry observations, re-entry flight data as well as mission concepts and planning.

Session 9: Future Outlook Closing Session

Conveners: JP. Lebreton (ESA Estec) J.Cutts (JPL)

The final session provides a synthesis of the issues raised during the workshop placed in the context of the programmatic framework covered in Session I. As in previous workshop, identifying opportunities for new initiatives involving international collaboration is a key objective.
