Water found on mars.!

Sorry I just had to do it.



Vast stores of water ice found on Mars Researches say melted water could cover whole of planet


Mars is unlikely to sport beachfront property anytime soon, but the planet has enough water ice at its south pole to blanket the entire planet in more than 30 feet of water if everything thawed out.

With a radar technique, astronomers have penetrated for the first time about 2.5 miles (nearly four kilometers) beneath the south pole’s frozen surface. The data showed that nearly pure water ice lies beneath.

Discovered in the early 1970s, layered deposits of ice and dust cap the North and South Poles of Mars. Until now, the deposits have been difficult to study closely with existing telescopes and satellites. The current advance comes from a probe of the deposits using an instrument aboard the Mars Express orbiter.

“This is the first time that a ground-penetrating system has ever been used on Mars,” said the new radar study’s lead author, Jeffrey Plaut of NASA’s Jet Propulsion Laboratory. “All the other instruments used to study the surface of Mars in the past really have only been sensitive to what occurs at the very surface.”

(NASA's Mars Odyssey spacecraft also carries instruments designed, among other things, to probe beneath icy polar surfaces.)

Deep probe
Plaut and his colleagues probed the deposits with radar echo sounding, typically used on Earth to study the interiors of glaciers. The instrument, called the Mars Advanced Radar for Subsurface and Ionospheric Sounding, or MARSIS, beams radio waves which penetrate the planet’s surface and bounce off features having different electrical properties.

The reflected beams revealed that 90 percent or more of the frozen polar material is pure water ice, sprinkled with dust particles. The scientists calculated that the water would form a 36-foot-deep ocean of sorts if spread over the Martian globe.


This map shows the thickness of the south polar layered deposits of Mars. The radar data indicate that the deposit, larger than Texas in area, is more than 2.3 miles (3.7 kilometers) thick in places, and that the material consists of nearly pure water ice with only a small component of dust.

But it proves that the planet could support it.

Yeah but it still doesn't have good conditions for life. Maybe humans will change that in the future.

Just because we have no proof doesn't mean life doesn't exist.

If there is water, there is a chance microscopic organisms live. And if this is the case, space trip to Mars. *All aboard!*

There would have to be a lot of them though and it would have to have food so it can survive. It just doesn't seem too likely.
