Life on Titan
Craig Carmichael
I’d like to talk about Titan’s duney “tidal marsh” seas, and life on Titan, which space scientists have missed.
- Titan: the most Earthlike planet in the solar system besides Earth: air (22 PSI), seas, lakes, rivers (of liquid methane). 1/7 gravity, 30 year year, 16 day days, 1/3 of Earth’s temperature.
- The gravitational workings of Titan’s once a day tides: why, the resulting fluid flows, the predictable and actual locations of the duney tropical seas and channels, Titan’s slow rotation.
Life:
- Breathing gas is hydrogen, as recently discerned by scientists.
- Earth: C + O2 => CO2
- Titan: C + 2 H2 => CH4
- Cassini Spectroscopic results show abundant benzene, especially at shorelines.
- Where Huygens landed: on top of a dune almost level with the sea surface.
- Huygens GCMS results show organics and complex chemical activities occurring on Titan’s surface.
- Huygens images show abundant aquatic vegetation that reveals the submerged dunes.
- Cassini images show forests of giant trees, lakes of changing levels filled with vegetation, plain as day. River channels are marked by taller trees.
Will bring pictures taken by spacecraft to illustrate.
