The final week of my annual February birthday month fund-raising campaign for Behind the Black has begun. I continue to be overwhelmed by the outpouring of support, including numerous donations and a surge of new subscribers willing to commit to donating anywhere from $2 to $25 per month. Wow! The numbers are too many to send out individual thank you’s, so please forgive me for thanking you all with this one announcement.


The campaign however must go on, especially because I have added more regular features to my daily workload. In addition to my daily never-ending reporting on space exploration and science, my regular launch reports, my monthly sunspot updates, the regular cool images, and the evening pauses I post each evening, I have now added a daily weekday post I have entitled "Today's blacklisted American." Its goal is not to discuss policy or politics, but to note the endless examples occurring across the United States where some jack-booted thug or thugs think it is proper and acceptable to censor, blackball, cancel, and destroy an innocent American, merely because that American has expressed or holds an opinion or is of a race or religion that is no longer considered acceptable to the dominant leftist and bigoted culture. I want to make clear to every American that a large number of your fellow citizens no longer believe in the enlightened concept of freedom of speech or the idea of treating each person by the quality of their character.


Instead, they wish to shut you up, and oppress you if you happen to disagree with them or have the wrong skin color. This evil must be exposed.


To continue to do this into the foreseeable future however I need your support. If you are one of those millions who read Behind the Black each month, please consider donating or subscribing. Regular readers can support Behind The Black with a contribution via paypal:

Martian pits or dark splotches?

Martian pits or dark splotches?

Cool image time! The photo to the right, cropped to post here, was taken on January 2, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a windswept sandy region of ridges and dunes with two dark features nestled between ridges.

What are these dark patches? At the available resolution they appear to be deep pits, with the one on the right having a significant overhang. And if these are pits, they would appear significantly different than most of the previously identified Martian pits, which are usually somewhat circular in shape. These features have very complex shapes, as if the pit is conforming itself to the terrain that surrounds it.

The resolution, however, is not good enough to confirm this interpretation. These dark patches could also be exposed volcanic material, darker than the surrounding terrain. The location, as shown in the overview map below, adds weight to this interpretation.

Overview map

The white cross indicates the location of these dark features, placing them inside the Medusae Fossae Formation, the largest deposit of volcanic ash on Mars. In other places in or near this formation where dust devils have blown the ash away the underlying volcanic material appears darker, though not exactly like this.

There is a third possibility, though more unlikely. These dark features might be volcanic vents, as this location is also located in what I like to label Mars’ volcano country. This is the least likely hypothesis, however, as the features bear little resemblance to other vents that I have seen so far on Mars. Can’t rule it out, however.

Ah, the uncertainty of science. Makes you want to go there and dig a little deeper to find out what these really are, doesn’t it?

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.

    Very unusual, curious.
    The lower right picture has a large circular rock like a big “cog artifact” in a lake of black goo…

    It’s the second time I noticed a circular object… In a prior photograph of a canyon contributing to a large flow that went off several cliffs… There’s a circular bridge crossing the canyon with a few objects on top of it. Too blurry to tell if it’s an obstruction, or a natural Bridge over the canyon.

    I’m inspecting this original picture, there’s a dozen black splotches on the ancient mud flood plain. No prominent “shadows” from the dune peaks… some of the black material appears along the crest of dunes like it’s a heavier particle different from the blown sand. (I wish it was in color, it might be dark blue) In other places, the blackness fills the low spots where there would be puddles or lakes.
    Because the position of the sun is mostly overhead, I don’t think they are windows. Dark material perhaps, uncovered by the weathering of billions of years. But this could be wrong as I can see lava flows? Like snake River beds all across the top of the picture. Now raised above the plain. Also in lower left at the base of one of the taller ridges with the largest deposit of black beneath it, the black has spread down wind like a vent, but it could just be the wind uncovering of some dark material underneath.

    So many mysteries. So many planets, so little time.
