Interesting news....

Liquid water 'lake' revealed on Mars - http://www.bbc.co.uk/news/science-environment-44952710

Cool (in more ways than one).

This is an enormous discovery in my opinion. Would it bring forward manned missions to Mars? 

Possibly more money spent on faster spacecraft engines.

An interesting find but dont build up hopes of it being proper lake, this will need more research to establish its credentials 

[Jeff-Colorado]

Remarkable discovery, although at a depth of 1.5 km, it will be difficult to get to. And at the relatively slow pace of exploration, how many years or decades will pass before this lake is explored?

[Alien 13]

I am not surprised, I always thought liquid water was quite common in certain areas after all the Martians need to drink.  I await the discovery of something similar on the Moon.

The lake is probably linked to the canals, which service underground cities ??

I knew Percival was onto something

This is a marvellous find though.

And a song by David Bowie......practically overused as a phrase these days it seems ?

It shouldnt come as a surprise that there is liquid water on Mars. Its underneath the polar ice cap............which is made of?.

frozen H2O.................water. It will be very useful if we ever get there. Extracting it shouldnt be a problem. Oil wells run deep and we can still get to the oil.

Biggest challenge will be that the cap changes in size so much each year.

What puzzles me is that although the ice cap shrinks during the seasons it keeps coming back, you would expect it to vanish quite quickly.

Its obviously being fed by the water below?.

Actually, mostly frozen carbon dioxide

Thats only good for making instant ice cream. It is liquid H20 underneath though?.

I will await confirmation. Another similar study failed to find any. Scientist are so keen to find water it has been found before only to find it was not?

Not as far as I know it is a single study with one instrument. The SHARAD instrument did not find it but there mybe reasons for that .

I will hold the Champaign for now.
