Scientists Say Liquid Water Found on Mars

Mars shocker: Liquid water lake found on the Red Planet
25 Jul 2018
Scientists have uncovered a "a stable body of liquid water" on Mars, in what some are calling a "game changer" in the search for alien life.

What is believed to be liquid water is sitting below Mars' southern polar ice cap and is described as a "well-defined, 20-kilometer-wide zone." 20 kilometers is roughly 12.5 miles.

The findings, which are published in the journal Science, were made possibly by Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS), an instrument that resides on the Mars Express spacecraft. MARSIS surveyed Mars' Planum Australe region between May 2012 and December 2015 and utilized radar pulses, sending them through the surface and the polar ice caps, ultimately measuring how the radio waves came back.

The pulses that came back created the aforementioned "well-defined, 20-kilometer-wide zone" and found that the radar reflected the brightness of the liquid water. The study's abstract notes that it is surrounded by "much less reflective areas," a sign that it is indeed water.

The team that wrote the study, including lead author Professor Roberto Orosei, have ruled out any other causes for the brightness. (more here)

It all sounds very exciting ,and is in mans quest for knowledge ,,,but ,,,if they find any sort of organism that could be defined as living ,they can do all the research they like ,but it has to be kept on Mars .

The very idea of bringing something that could be described as having life back to this planet to me is unthinkable .

Cheers.

Are you saying that Ripley was right to kill the Alien!

I didn't mean it as a 'chicken little' comment ,more an element of caution, but how may times has as lid been opened on something that has turned out 'much to a scientist surprise' less than beneficial to the population at large?
I know authorities dealt competently and diligently with the 'Samaritans purse' event,,but, if it occurred here it would get me a bit worried .
There is a quote from an infamous Australian 'Chopper' that goes "Fear is gods way of stopping us from tongue kissing tiger snakes"
i believe this comment to be very accurate.

Taking something from its natural environment where it is exists in a congruent state and placing it in an alien state [which is Earth to anything from Mars] is peeking under the lid of a can to me.

Hey ,but that's just me,I'll stick to Chop's tenet.

Cheers.

I saw this. it's pretty awesome. There is plenty of evidence that Mars had large bodies of water on the surface in the past. The problem is, it's size and lack of magnetic field didn't provide enough gravity and protection from the sun to sustain the atmosphere. It will be interesting to see what they come up with to go investigate the water finding.

The old Arnold S., Sci-fi movie, "Total Recall", has already told us a lot about Mars!!

So have they or do they believe they have?

It seems they make this same claim every few years and the head line states they have but then the article goes to say they think they have yet they never do so it will be interesting to see what comes of it.

They have to keep the grants/Gov. money coming in, right!!
