A scientist has worked out what a 'waterfall' might sound like on
Titan, ahead of a NASA mission that could find oceans on Saturn's
Professor Tim Leighton, of Southampton University, recorded a
waterfall in Hampshire and worked out the soundwaves the equivalent
would make on the moon Titan, given the prevailing conditions:
The general temperatures on the surface are likely to be around
minus 180C, with pools of liquid methane - and possibly rivers and
seas of it too. And the 'air' is nitrogen.
A fall of water would obviously be frozen solid, but a
methanefall is quite another matter.
A probe is due to land on Titan mid-January, 2005.
Professor Leighton embarked on the research after seeing an
artist's impression of a waterfall on Titan, by recording an Earthly
waterfall and processing the soundwaves to adjust for how they'd
behave in Titan's conditions.
