Made a post here, apparently after the 'timed out' notice, which usually issues after a post, there is a delay to presentation updating. I'll post a couple of examples to show the rudimentary nature of our science state of affairs. These indicate the degree of travel necessary to find the presumed limits of common life on Earth, not even presuming how it can be assumed as similar to life on another space object.
I may have to reissue the prior post from tonight.
Interesting that the formation of the second linked article is based upon iron, chloride, and organic associated common chemistry. What do we assume is life?
Mars has an active iron chloride salt and ice process resolved by satellite sensing. It appears to be altering the slopes of Mars, repeating the process, and interactively isolated within domains of active chemistry which change both geology chemistry, but the state of water ice, giving a by-product we haven't been close enough to observe directly.
Whatever we find it will be only by direct observation over decades of research there on Mars.
It required forty years and much technology to get to Mars only to pass by all the results suggesting life or similar activity. We still can't get to the active sites of even this one chemistry supposition forty-five years after it was designed conceptually .
We need dozens of rover landings to find a thousand additional mysteries to solve.
Finding life or undetected chemistry is a long slow path.
As the source of life not found cannot be designed well, how can exclusion or denial be possible? On Earth we are in the first few centuries of 'real' science.
When I presented views on Earth of hematite layered spheroidalism shapes exhibiting salt encrustations as a product of the throughput passage of complex salutes or molecular chemistry, or other life-like interactions, I got not even a single comment or observation or detailing by contributors on this blog.
How can we presume either no life, or the source of life on Mars when we have no interest in the similar processes on Earth? The comedy is similar to the background of the madness in the current presidential campaign of 2016-2017.
We should be building a base of understanding and resolution, yet the basics are not yet explored on Earth.
Will my prior post of tonight be presented eventually, or is it 'disappeared'?
Are the 'berries' still a contender for a detailed chemistry process similar to Earth type hematite spheroidalism, or is there agreement that life was not involved in both Earth and Mars examples of similar physical results?
The Earth examples are in relative association with oil and gas sources.
