In­frared eye on Ti­tan

All About Space - - Launch Pad -

NASA’s Cassini space­craft is still spring­ing sur­prises about the Satur­nian sys­tem, in par­tic­u­lar the sys­tem’s largest moon, Ti­tan. Cassini’s Vis­ual and In­frared Map­ping Spec­trom­e­ter (VIMS) in­stru­ment gath­ered 13 years’ worth of in­frared data of the 'Earth-like' satel­lite from which th­ese in­frared maps were formed.

Look­ing at Ti­tan in the vis­i­ble light wave­length doesn’t re­veal much, as the sur­face of the moon is blocked by an or­ange, hazy at­mos­phere. The in­frared ob­ser­va­tions pro­vide a win­dow to the sur­face, re­veal­ing its com­plex ge­ol­ogy.
