Workshop on Planetary Volcanism and Mantle Dynamics Observatoire Midi-Pyrénées, 29th – 30th March, 2012
Cerro Galan (plus grande caldéra volcanique du monde, 40 km de diamètre, à 4000 m d'altitude dans les Andes)
The magmatic activity of solid planets is the surface expression of heat loss from mantle conversion and heat gain from radiogenic elements. This view has motivated the reconstruction of the thermal evolution of the Earth and more recently of the other solid planets. Geophysical approaches (heat flow measurements, or indirect estimates of heat flow from the elastic thickness of the lithosphere), numerical models of mantle dynamics, and petrological/geochemical analyses provide different insights into planetary evolution. The proposed workshop is aimed at stimulating exchanges between these various fields of research. In details, the following topics will be covered:
- Magma ocean crystallization and consequences
- Modeling of mantle dynamics, thermal evolution constrained by paleo-heat flows
- Ancient (archean) volcanism on the Earth, dyke swarms
- Igneous mineralogy of Mars, magmatic processes and links with thermal evolution
- Magnetic anomalies on Mars
- Morphology of volcanic landforms, rheology of lava flows, explosive volcanism
- Magmatism on minor planets
A particular focus will be given to Mars which exposes a 4 billions year long record of magmatic rocks. The workshop is held in Toulouse, Observatoire Midi-Pyrénées. Each 20’ oral presentation will be followed by 10’ for questions/discussions. A couple of time slots are scheduled in the program to encourage further exchanges among the participants.

9th International Planetary Probe Workshop (IPPW-9), Toulouse, France, June 18-22, 2012
The 9th International Planetary Probe Workshop (IPPW-9) in Toulouse, France on June 18-22, 2012 will be hosted by ISAE ( Institut Supérieur de l’Aéronautique et de l’Espace) on its campus. The goal of the workshop is to bring together scientists, technologists, engineers, mission designers, and policy makers interested in the technological challenges and scientific opportunities in the exploration of Solar System atmospheres and surfaces using atmospheric entry and descent probes. The 9th workshop will build on the success of the previous workshops to promote international cooperation in probe missions to solar system bodies.
2012 promises to be an exciting edition, with the space community engaged in operating, building or planning many exciting missions to the Moon, planets, their satellites, asteroids and comets. 2012 will see: the arrival of the long-waited Mars Science Laboratory in the Gale crater, together with the continued operation of the Mars Exploration Rover mission, and the Philae comet lander still on its way to its destination. In addition to the five-day workshop, a two day short course is normally held on a related topic during the preceding weekend. The topic selected for IPPW-9 is “ Probe Science Instrumentation Technologies ” (June 16-17, 2012).
