Scientists have found a vast lake underneath the surface of Mars, a big breakthrough in the search for alien life. This is the first time a sable water supply has been detected on Mars, resolving decade old discussions if there is any water at all..because if no water then no life.
The vast lake lies underneath Mar’s southern pole and stretches 20 km across. Long ago Mars was a warmer and wetter, with significant bodies of water.
The discovery was found by the Mars Express spacecraft. Radar pulses penetrate the surface and the ice caps on Mars and are measured on their return. The data generated showed a very sharp change of signals from about 1.5 km beneath the surface. The data was compared to that seen beneath the Antarctic and Greenland. The suggestion being that mycobacterial life could live in these extreme condition.
It is even colder on Mars than in the Antarctic or Greenland, making the discovery of liquid water even more amazing. The water itself is probably a briny sludge..the salt being why it is liquid at all.
It remains to be seen if there are more subsurface reservoirs..stay tuned.
