High-Mass Organics Refractory organics with m >> 100 Da comprising insoluble organic matter (IOM): • encode formation processes and timescales (aromatic / aliphatic) • associate with key ISM organics (amino acids, nucleobases, sugars) • dominate the organic fraction of comet nuclei (as they do in c-chondrites) All Carbon Inorganic Organic Elemental Carbonates, etc. SOM (Free) IOM (MM) Volatile (Py) Refractory (nonPy) W.

Outer Planetary Satellites Europa Titan • Ocean? • Life? • Ice chemistry is key goal • Surface vs subsurface • Radiation • Fissure upwellings • Lander w/drill • Hard mission! • Seas! • “Pre-biotic” chemistry • Atmospheric density is high • Long-term goal: A mobile lander (or aerobot/lander) equipped with a mass spec! • Expensive but not so difficult to do.
