Martian Chronicles

Not the mini-series or the book by Bradbury….my “Chronicles” are about the findings on the “Angry Red Planet” (a B movie from the 50s)…..

There have many that believe that Mars had an atmosphere way before the Earth…

Asteroid impacts may have helped make Mars a more life-friendly place — and not just by delivering water and the carbon-based building blocks of life as we know it to the Red Planet.

Incoming space rocks may also have helped seed Mars with biologically usable forms of nitrogen long ago, if the planet’s atmosphere were rich in hydrogen (H2) back then, a new study reports.

In 2015, NASA’s Mars rover Curiosity discovered nitrate (NO3) in the rocks of Gale Crater, the 96-mile-wide (154 kilometers) hole in the ground the six-wheeled robot has been exploring since 2012. Nitrate is a “fixed” form of nitrogen; life-forms, at least as we know them on Earth, can nab NO3’s nitrogen and incorporate it into biomolecules like amino acids. That’s in contrast with “unfixed” gaseous nitrogen (N2), which features two tightly bonded, inert and relatively inaccessible nitrogen atoms. (This inaccessibility helps explain why farmers fertilize their fields, even though Earth’s air is nearly 80 percent N2.)

Even to the point of having huge flowing rivers……

Huge rivers seem to have been flowing across Mars relatively recently, scientists said.

The flowing water came in rivers much bigger and more powerful than those seen on Earth, they said. And they seem to have stuck around far longer than we had realised.

The raging water courses carved deep channels into the Martian surface at “hundreds of locations”, said scientists.

Actually that water may still be there just a lot deeper than we thought…..

Researchers at the University of Southern California dropped a bold claim Thursday: based on a new analysis, Mars likely harbors a “deep groundwater” system that probably extends far beyond the planet’s poles and bubbles to the surface through cracks in craters.

“We have seen the same mechanisms in the North African Sahara and in the Arabian Peninsula, and it helped us explore the same mechanism on Mars,” researcher Abotalib Abotalib said in a press release.

Did Mars and Venus have a atmosphere that could be said to be “livable”…..

If you could travel back in time to the early stages of the Solar System, some 4.5 billion years ago, you wouldn’t find one life-friendly world, but three. Venus, Earth, and Mars all looked very similar from a planetary perspective, as they all had substantial surface gravity and atmospheres similar to Earth’s in thickness. There were volcanoes, watery oceans, and complex interactions that enabled these worlds to retain the heat they absorbed from the Sun.

The Rovers carry out scientific experiments and readings…..and one of the readings was seismic activity……

Since NASA’s InSight lander touched down on Mars at the end of last year, the plucky little surface probe has spent months getting carefully situated so that its special seismometer could carefully listen for “marsquakes” — a neologism for earthquakes that occur on Mars, rather than Earth, as you probably guessed. Observations of marsquakes will help determine just what’s going on inside Mars, and to what extent it is still a geologically active world. We know Mars was very geologically active in the past; notably, it has the tallest mountain of any planet in the solar system.

While InSight hasn’t heard earth-shaking marsquakes yet, a Science Magazine interview with Philippe Lognonné, a planetary seismologist at Paris Diderot University who manages the team that runs the seismometer, revealed that the lander’s instrument has detected a different kind of rumbling known as microseisms. They are the first of their kind to be detected on another planet.

Life is where you find it……does that include Mars?

The NASA Mars Rover Curiosity has been going around the Red Planet in search of new areas for drilling after encountering some technical problems early this month. During one of its excursions, it was able to take a snapshot of some really nice pebbles with some odd yet interesting details.

In a photo released on the NASA website, one can see what looks like normal pebbles from a stream bed. But upon closer inspection and with some enhancement from Kevin M. Gill, a NASA software engineer who does processing of space images, a picture of perfectly round gray pebbles can also be seen.

 

According to CNET, the pebbles, which are now being studied by the space agency’s rover team, look very similar to rocks found in another area of the planet. These rocks were discovered by the now-deceased NASA rover Opportunity and were labeled as “blueberries.”

Mushrooms in the Martian story?

From NASA’s rovers and landers to David Bowie, one question about the Red Planet remains sadly unanswered. Is there life on Mars? Now a controversial review paper has claimed that the answer is a resounding yes. And it’s definitely going to start a big debate.

The paper includes images taken by Curiosity and Opportunity of what the researchers are calling fungi, lichens, and algae growing on Mars. So, are there really mushrooms growing on Mars, like some are reporting?

The paper, titled Evidence of Life on Mars? is published in the first edition of a brand new journal, the Journal of Astrobiology and Space Science Reviews, and looks at almost 200 peer-reviewed studies debating curious structures, seasonal changes in methane, and the possibility that life has traveled between planets. The journal itself calls the evidence controversial and had six independent scientists and eight senior editors peer review it, three of which rejected it.

In The 50s a bad SciFi movie, The Angry Red Planet” had this big spider-like creature tormenting the astronauts…..but in real life the Martian spider is “Blue”…..

David Bowie sang about his sci-fi persona Ziggy Stardust performing with the Spiders from Mars, and now it turns out there’s a “spider” on Mars after all.

An image captured by a European Space Agency (ESA) orbiter recently showed what appears to be a very hairy, blue spider extending its “legs” across the Martian landscape.

But in reality, the so-called spider is a sprawling pattern left behind on a ridge by a frenzy of dust devils, when hundreds or even thousands of whirling tornadoes formed in the area, ESA representatives said yesterday (March 14) in a statement

The “Chronicles” continue and the news is made and man waits for his chance to step onto the “Angry Red Planet”…….

  1. The term ‘relatively recently’ takes on a whole new meaning when applied to the universe. I can’t get too excited about such ‘discoveries’, as I will long be dust before anything comes of them. 🙂
    Best wishes, Pete.

    1. I like the science that went into these “discoveries”…….maybe something good will come from them……but I too shall be dead long before it does….if ever….chuq

  2. That is where the earth will eventually be, before the sun explodes and burns up all the planets. Not in the next few hundred or few thousand years, of course.
