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.

While most normal people spend their Saturday evenings going out to dinner followed by either a movie or a show, I spent this past Saturday doing something entirely different: counting bats!
There is a local cave here in the Tucson area that is a maternity colony for one species of bats. During the summer the females gather here to gossip and then give birth to their babies, after which they move on until next year. Because of a desire to help these bats, a few years ago the managers of the cave decided to close it during the summer months. This way humans wouldn’t be there to disturb the mothers during their labor.
The managers also decided to do regular bat counts of the bats leaving the cave each evening to feed, in order to get an estimate of the population size. To everyone’s delight they found the numbers rising year-to-year, following the summer closure. The total population of bats isn’t actually going up, but it appears that bats are finding this cave to be a good place to give birth, so more and more of them are making it their summer residence.
In the end the situation will contribute to an actual rise in population, as providing the maternity colony a safe haven will allow for more successful births and more babies.
In the past three years the bat count numbers over each summer would exhibit a typical bell curve, going up and then declining as the summer progressed, with the largest numbers ranging between 75 to 150 each night. However, last year there was one evening in which no bats left the cave. The bat biologist leading the bat count, Sandy Wolf, has theorized that this might be because the mothers are synchronizing their labor so that everyone gives birth at the same time and, because of that, on that night no one exits for feeding.. She knows that some species do this, but for this particular species such behavior has never been documented.
Anyway, she decided to find out. This has required that someone be at the entrance counting the bats at least every other evening. (In past years the counts were only done about once a week.) This has required more help, and thus Sandy has called for volunteers to do the work.
And that is how I and fellow caver Jerry Isaman ended up hiking up the hill to the cave with digital camera, infrared lights, and monitor this past Saturday.
The camera and infrared lights were aimed at the entrance, with the monitor set up about thirty feet away, hidden from the entrance. We could watch the monitor and easily see bats entering and leaving, with me counting those going out and Jerry counting those going in. The camera meanwhile taped everything, so that our counts could later be confirmed and checked for accuracy.
I had expected this would be both boring and difficult to do. You start staring at the monitor unceasingly at around sunset, and nothing usually happens for the first fifteen minutes or so. Then the first bat flies out. I think “Whoopie!” as I click my clicker counter.
I found. however, that spotting the bats was far easier than expected, and that the work was not really boring at all. Once the first bat left things got busy for about a half hour, with bats flying out about 2 to 4 per minute. Then things quieted down, and after 90 minutes, when nothing flew out for 10 full minutes, we shut down and packed up.
The most challenging part of the count was when a bat decided to go back into the cave. It appeared that many of them had to plan their entrance and couldn’t do it on the first attempt. They would circle around several times, dive toward the entrance and then change their mind the last second, repeatedly faking Jerry out, who was about to count them for re-entering the cave and now could not. I meanwhile had to make sure I didn’t count them as exiting the cave.
The coolest thing about Saturday was the count itself: We counted 218 bats leaving, the highest count of the year. Though we were not there on the night no bats came out, confirming Sandy’s theory, our count once again indicated that the population using the cave is increasing.
I hope to do this again later this summer. It might not be the traditional way to spend an evening, with dinner and a movie, but it certainly is more interesting.
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.
