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.

In the past year the monthly image releases from the high resolution camera on Mars Reconnaissance Orbiter (MRO) archive have frequently included newly discovered pit entrances. Each time I have written posts highlighting these new pits, in June, July, November 2018 and January 2019. In fact, this is happening so frequently I could almost label it a monthly update!
The November release imaged three pits found on the southern flanks of Arsia Mons. The January 2019 release found several north of the volcano, two of which are very close to the two middle new pits highlighted above. The February release, which is the focus of this post, included four more pits, shown above, all located north and west of Arsia Mons, as shown in the overview map to the right.
Pits 2 and 3 above appear to belong to a cluster of pits all located in the general area between Arsia and Pavonis Mons. (You can see their uncaptioned releases here and here.) Most sit alone on a flat somewhat featureless plain. Sometimes there are flow features nearby, but each pit usually seems to sit unique and unrelated to these other faint features.
Pit 1 is very intriguing in that it sits amid a very long chain of pits and canyons, all aligned, as shown in the image below and to the right.
It thus reminds me of the pit I featured on February 5, 2019, though less exciting. The February 5 pit was located in an area with features suggestive of catastrophic flooding from flowing water, while today’s pit is more likely the result of volcanic processes, located as it is on the flank of a large volcano.
Still, when Mars was wetter this pit, as well as the full string of pits it is part of, could have also been shaped by water erosion. Someone with better knowledge of the geology and chemistry here would have to answer this question, assuming we have the data.
Finally we have pit #4, which sits much higher on the flanks of Arsia Mons, with the slope going downhill from the southwest to the northeast. The full image reveals a second larger pit to the east, just on the edge of the frame. Unfortunately, no other images have taken by MRO anywhere near this location, so we do not know if there are more such pits here. I would however not be surprised it these are skylights into lava tubes below, and that with more high resolution images we will discover more skylights throughout this area.
Would any of these pits provide access to underground ice? Possibly. They sit high in elevation, which is a strike against. However, the evidence of past glacial activity west of Arsia Mons, as well as the clouds that seasonal form above the volcano, are both strikes in favor.
We won’t really know however until we go there.
Every July, to celebrate the anniversary of the start of Behind the Black in 2010, I hold a month-long fund-raising campaign to make it possible for me to continue my work here for another year.
This year's fund-raising drive however is more significant in that it is also the 10th anniversary of this website's founding. It is hard to believe, but I have been doing this for a full decade, during which I have written more than 22,000 posts, of which more than 1,000 were essays and almost 2,600 were evening pauses.
This year's fund drive is also more important because of the growing intolerance of free speech and dissent in American culture. Increasingly people who don't like what they read are blatantly acting to blackball sites like mine. I have tried to insulate myself from this tyrannical effort by not depending on Google advertising or cross-posts Facebook or Twitter. Though this prevents them from having a hold on me, it also acts to limit my exposure.
Therefore, I hope you will please consider donating to Behind the Black, by giving either a one-time contribution or a regular subscription, as outlined in the tip jar below. Your support will allow me to continue covering science and culture as I have for the past twenty years, independent and free from any outside influence.
