1. Research in the WROONA Group Daniel Mège FNP project TEAM 2011/7-9 October 2011 - June 2015 + one or two unrealistic ideas for future instrumental development

2. Wroona is a small blue world in Wroona system, located on the far edge of the Inner Rim in the Rayter Sector. The planet's continents are separated by vast oceans, and their blue-sand beaches stretch for thousands of kilometers. The near-human inhabitants of Wroona, numbering over seven billion, are a blue-skinned species with a lighthearted and optimistic outlook on life.

9. Favourite study area Valles Marineris tectonic volcanic sedimentary glacial, fluvial, aeolian - Window to the Martian crust (10 km deep) - Fossilized environmental successions in the landscapes - Variety of geological processes common to Mars and Earth

10. 130 km 8.5 km Valles Marineris The whole Mars history is there!

11. What do we need? Ideas more high resolution imagery better spectral data better topography … more and better everything… We need to go to the field! Check the surface (geology) Check the subsurface (geophysics) Let's be innovative!

15. Let's explore the field! Geological field work Valles Marineris is nice It has recorded on limited surface areas more geologic events than any other site on Mars These successions are concentrated on small surface areas It has the reputation of being unpredictable (surface roughness/ellipse problem) It is nonsense! MSL could have landed in a place similar to this in Gale Crater

16. MSL landing site proposed by Chonacki and Hynek MSL landing site proposed by Chonacki and Hynek 100 km 5 different sites were proposed in VM for MSL

17. How to get safely to nice rock outcrops? But the engineering constraint remains: a huge surface area must be smooth for landing corollary there is not much to see

18. Great discoveries are not planned! Technological challenge Technological challenge Considered option: Back to the basics Back to the basics of space exploration: like the incredible Curiosity landing EXPLORE instead of find what we are expecting to find like the New Horizons spacecraft Scientific and technological visibility Scientific and technological visibility

23. Radio communication Science payload: MS/HS camera and other sensors (thermal, mag…) Automatically inflattable for higher portance and instrument protection between observation sites Internal gravity balance for instrument orientation control Spring/hammering mechanism to start blocked balls or change the ball orientation for new measurements 10, 20, 50 items released in one flight?

24. ARES platform (Joel Levine, NASA LaRC) prepared for another NASA Scout mission Carriers that have already been developed: KittyHawk glider, NASA Scout mission (Wendy Calvin, UNR), was to be flown above Valles Marineris in 2003 for the 100th anniversary of the Wright brothers' flight ARES Scout mission payload

25. Let's make it true!
