  14. Huygens Investigations

  15. DISR: first images DISR: first images drainage canals; fluvial activity Shoreline dry lakebed Methane Ground Fog

  16. 16 km

  17. DISR: side-looking imager h: 8 km res: 20 m

  18. DISR: 360 Panorama ground fog h: 8 km; resolution: 20 m Wind drift velocity: 1-2 m/s landing site

  19. SSP: Impact on Surface ‘wet sand or clay’ (crème brûlée)

  20. DISR: on the surface ‘orange tint from reflectance spectra’ 5 cm 85 cm ‘dirty water ice, not hydrocarbon ice’

  21. If it was easy, then it wouldn’t be worth doing or someone would have done it already. D. Atkinson ( i.e., “Nothing is perfect….”)
