More evidence Mars’s glaciers formed across many ice ages

The uncertainty of science: New research using the boulders found on the top of Martian glaciers has now strengthened the evidence that Mars must have undergone many previous ice age cycles going back as much as 800 million years, with those glaciers waxing and waning during each cycle.

This new data helps map the cycles earlier than 20 million years ago, which have been difficult to map out based solely on the orbital data available from Earth and from Mars orbit. The results suggest that before then there were from six to twenty additional cycles during the last 300 to 800 million years.

These numbers are decidedly uncertain. It is likely that there were many more cycles, as suggested by the many layers seen at the edges of the north and south polar ice caps.

Be aware as well that if you read the press release you should know that it falsely implies that this research is the first to map out these ice age cycles. This is not true. All this research has done is provide more evidence for cycles prior to 20 million years ago, cycles that scientists have long believed must have happened based on other data.

In the end, for us to map out the full climate history of Mars will require numerous ice core samples at the planet’s poles, something that will not be possible until people are living and working on Mars routinely.

Pioneer cover

From the press release: From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.

 
Unfortunately, that is exactly where that journey takes him.

The vision that Zimmerman paints of vibrant human colonies on the Moon, Mars, the asteroids, and beyond, indomitably fighting the harsh lifeless environment of space to build new societies, captures perfectly the emerging space race we see today.

He also captures in Pioneer the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. It is that spirit that will make the exploration of the heavens possible, forever, into the never-ending future.

    So many, many features on mars as per the photos here, duplicate the unique look of soil or sand and how it looks under water.

    I wrack my brain for instances, looking at some of those photos, of where I’ve seen dirt or sand that looked like that that was above-ground, and after six-plus decades living near large bodies of water and playing in and around them from the time I could walk … now I even look for things that “look like mars.” Except for some kinds of dry dunes, when I see dry dirt or sand that mimics the look of photos from mars, I know that the dirt or sand got that way only because it had been submerged in water for some time. All other formations, even on dunes, looks “dry formed” to my eye.

    Oh well, just my thoughts. How cool to be able to see photos of mars and have some idea of what we’re looking at due to folks who’ve invested heart and effort. THANKS from these quarters.
