Q. Cassini spacecraft from NASA has discovered liquid hydrocarbons on which moon?- Published on 12 Aug 16a. Io
b. Ganymede
c. Europa
d. Titan
ANSWER: Titan
NASA’s Cassini spacecraft has discovered steep sided canyons 100s of meters deep on Saturn’s moon Titan that are flooded with liquid hydrocarbons
- This presents first evidence of liquid filled channels on Titan
- It also represented the first observation of the deep canyons on Titan
- Observations show that channels including the Vid Flumina are narrow. less than a km wide and with steep slopes at 40 degrees and measured 240 to 570 m from top to bottom
- Branching channels appear in radar images much like Titan’s methane rich seas
- Channels might also be filled with liquid but direct detection has not been made till now; earth based examples of canyon caring processes are found along Arizona’s Colorado river
