On Mars, Curiosity Rover helped establish the existence of flowing, liquid water on the Martian Surface some billions of years ago. This water would have been highly acidic, pooling up in the lower places, and probably (from what I currently know) not part of a water cycle with condensing and precipitating water (rain).
Long ago, Mars had enough of an atmosphere to support this liquid water, but lacking the size and electro-magnetic field generated by Earth’s core, Mars slowly had all the water molecules combine with other particles blasting away at the surface from space. Slowly, the water dwindled, as the atmosphere drifted away, and so the temperatures dropped.
So did protection from the Sun’s radiation.
Imagine sub-freezing temperatures and free radicals bombarding the near atmosphere-less Martian surface (oxidized and rusted red, barren), but below the Martian surface lurk big blocks of briny ice; ice with freezing cold, incredibly salty water and maybe just enough O2 to support some microbes.
Worth thinking about.
What are you doing with your imagination?
‘Due to the scarcity of O2 in the modern Martian atmosphere, Mars has been assumed to be incapable of producing environments with sufficiently large concentrations of O2 to support aerobic respiration. Here, we present a thermodynamic framework for the solubility of O2 in brines under Martian near-surface conditions. We find that modern Mars can support liquid environments with dissolved O2 values ranging from ~2.5 × 10−6 mol m−3 to 2 mol m−3 across the planet, with particularly high concentrations in polar regions because of lower temperatures at higher latitudes promoting O2 entry into brines’
Jezero crater, where Perseverance has landed, has both inflow and outflow channels, like a holding tank. There is a deposit plain near the inflow channel. If you’re going to go digging in the Martian dust, digging through what was once muck, hoping to find some evidence of microbial Martian life, Jezero crater is as good place as any to do it.
I noticed a tear in my eye watching video of the rover touching down. So much hard work. So many deep dreams and aspirations made into reality. A functional robotic exploratory team is slowly being built, with little outposts on other worlds.
For those who didn’t ask, Dear Reader:
Liberal Idealism–>I want to live in a free and human world, constantly progressing, full of human compassion, equality and justice. People, and people like myself, are generally good. Our change is good, and ought to be in charge–Output 1: Technocratic Bureaucracy–>Process 1: Change-focused ideas are in positions of key institutional leadership and authority (conserving certain elements of the past according to liberal ideals, excluding others). Science is invoked by many non-scientific actors. Process 2–>Institutional Capture by Ideologues and True-Belief from radical-change agents who believe that no authority is legitimate, and that it’s all power and no truth.–>Behind the Scenes: The people dedicated to an institution’s mission and purpose are fighting with the people who control the promotions within the institutions, and the loudest activist voices often win (see Jerry Pournelle).
Examples: See the NY Times, many Grant Foundations (Ford, Poetry), and many colleges and universities. See also, Health and Education departments. Most Liberal publications are now negotiating with the radical discontents within them. Such radicals, when not claiming collectivist supremacy, claim, from within the postmodern morass, a certain kind of feeling-first irrationality and primacy of Self (an irrational and mystic response to the ‘oppression’ of reason and the sciences).
Deeper Reasons Why: The Liberatory model of freedom (freedom against the oppressor, supposedly for the ‘victim’ and ‘oppressed minorities’) is an utopian and ideological model. Such a worldview has profound authoritarian/totalitarian implications. The ‘personal is political’ makes all areas of life (knowledge, sports, break-rooms) into political arenas. The Utopian promise of people actually getting along is pushed ever further into the future at the cost of people…you know….getting along in the present. Mediocre people and bad ideas are in charge. The easiest outlet for blame is anything standing in the way of progress (religion, tradition, liberal dissension, those who conserve).
What the Liberal idealist (and many anarchists) likely get wrong about human nature: People need ‘low-resolution’ ideas to make sense of reality, hierarchy, death, uncertainty and fear. This is an emergent feature within ourselves, and ignored at our peril. Human behavior, in aiming to be morally good and true, must be restrained, honorable and focused on consent. If such ideas and behavior are not incentivized into models of authority, then worse men, and the worse in men, will come to be in charge.
The more religious, frontier and freedom, flag and country type of America I once knew (with all its flaws) is looking more like a minority position these days.
Any pushback is welcome.

Shelby Steele and his son, Eli, have made a documentary about the killing of Michael Brown, and what happened in Ferguson. A lot of what seems to be the truth is not what many people claiming to have the truth are saying. Many of those people are in charge:
Who can afford to speak out?
Maybe if you’re a Stoic living on the fringes, whose needs are lesser than the punishment exclusion can bring. Maybe if you don’t have anyone directly dependent on you for love, security and safety.
Maybe the people with ‘F-You’ money who actually say ‘F-You’. The really well-to-do and the academic. I’m not holding my breath.
