Cassini Gets New Views of Titan’s Land of Lakes

25 October 2013

NASA’s Cassini spacecraft has obtained new pictures of the liquid methane and ethane seas and lakes that reside near Titan’s north pole, revealing new clues about how the lakes formed and about Titan’s Earth-like “hydrologic” cycle, which involves hydrocarbons rather than water.

With the sun now shining down over the north pole of Saturn’s moon Titan, a little luck with the weather, and trajectories that put the spacecraft into optimal viewing positions, NASA’s Cassini spacecraft has obtained new pictures of the liquid methane and ethane seas and lakes that reside near Titan’s north pole. The images reveal new clues about how the lakes formed and about Titan’s Earth-like “hydrologic” cycle, which involves hydrocarbons rather than water.

This image maps infrared colors onto the visible-color spectrum, revealing differences in the composition of material around the lakes. The data suggest parts of Titan’s lakes and seas may have evaporated and left behind the Titan equivalent of Earth’s salt flats. Titan’s evaporated material is thought to be organic chemicals originally from haze particles that dissolved in liquid methane. They appear orange in this image against the greenish backdrop of Titan’s typical bedrock of water ice.

“It turns out that Titan’s north pole is even more interesting than we thought, with a complex interplay of liquids in lakes and seas and deposits left from the evaporation of past lakes and seas,” said Jason Barnes, a scientist at the University of Idaho.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency.

타이탄에도 계절이 있고 날씨 변화가 심해서 이렇게 좋은 광경은 키시니도 잡기 힘든 모양인디, 초록색은 지하에 물의 얼음이 있다고 추측하고 곳이고 황색 부분은 유기화합물로 보인답니다. 소금도 있다고 하는디, 거기에 미리 가서 한 만평쯤 깃발을 꽂으면 어떨가 싶네 ㅋ ㅋ ㅋ ㅋ
