Readers! A November fund-raising drive!

 

It is unfortunately time for another November fund-raising campaign to support my work here at Behind the Black. I really dislike doing these, but 2025 is so far turning out to be a very poor year for donations and subscriptions, the worst since 2020. I very much need your support for this webpage to survive.

 

And I think I provide real value. Fifteen years ago I said SLS was garbage and should be cancelled. Almost a decade ago I said Orion was a lie and a bad idea. As early as 1998, long before almost anyone else, I predicted in my first book, Genesis: The Story of Apollo 8, that private enterprise and freedom would conquer the solar system, not government. Very early in the COVID panic and continuing throughout I noted that every policy put forth by the government (masks, social distancing, lockdowns, jab mandates) was wrong, misguided, and did more harm than good. In planetary science, while everyone else in the media still thinks Mars has no water, I have been reporting the real results from the orbiters now for more than five years, that Mars is in fact a planet largely covered with ice.

 

I could continue with numerous other examples. If you want to know what others will discover a decade hence, read what I write here at Behind the Black. And if you read my most recent book, Conscious Choice, you will find out what is going to happen in space in the next century.

 

 

This last claim might sound like hubris on my part, but I base it on my overall track record.

 

So please consider donating or subscribing to Behind the Black, either by giving a one-time contribution or a regular subscription. I could really use the support at this time. There are five ways of doing so:

 

1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.

 

2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation. Takes about a 10% cut.
 

3. A Paypal Donation or subscription, which takes about a 15% cut:

 

4. Donate by check. I get whatever you donate. Make the check payable to Robert Zimmerman and mail it to

You can also support me by buying one of my books, as noted in the boxes interspersed throughout the webpage or shown in the menu above.


Saturn now has 145 known moons

Using ground-based images analyzed in a new way, astronomers have discovered an additional 62 small moons orbiting Saturn, giving the ringed gas giant a total of 145 known moons.

The data used by the team was collected between 2019 and 2021 in three-hour spans by the Canada-France-Hawaii Telescope (CFHT) on top of Maunakea in Hawaii. It allowed the astronomers to detect moons around Saturn as small as 1.6 miles (2.5 kilometers) in diameter. That’s about two-thirds the length of Hollywood’s Walk of Fame.

Though some of the moons had been spotted as early as 2019, it takes more than sighting an object close to a planet to confirm it is a moon and not an asteroid making a brief close passage to that planet. To change these objects from “suspected moons” to “confirmed moons” of Saturn, the astronomers had to track them for several years to ensure each is actually orbiting the gas giant.

Performing a painstaking process of matching objects detected on different nights over the course of 24 months, the team tracked 63 objects that they ended up confirming as moons. One of these satellites was revealed back in 2021, with the remaining 62 moons gradually announced over the past few weeks.

To a certain extent, this declared number of moons around Saturn is utterly irrelevant. Think about it. Every single object in its rings should be defined as a moon, totaling hundreds of thousands. At some point the question of what defines a moon becomes the relevant question.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 

The print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

    Defining anything has a certain degree of arbitrariness in the process.

    Earth has two rotational poles, North and South. What about the North Pole necessitates not calling it the South Pole and the other the North Pole?

    To me, ‘moon’ means some object large enough to stand on, not something you can only step on.

    Mass and gravity make the definition less arbitrary if not agreeable.

    I’ll go ahead and suggest my own definition of “moon” versus some random object just passing through the space, or a captured object.

    1. It must have a permanently-stable (or at least, permanently variable) orbit around the planet.

    2. It must be sufficiently large and/or massive that it’s own gravity has formed it into a sphere.

    Note that under this definition, Mars would no longer have any moons since Phobos and Deimos are very certainly not spherical. For Saturn, Titan, Rhea, Dione, etc. would all be considered moons, but the smaller debris of irregular bodies would not. We’ll just call them captured satellites.

    How’s that for splitting hairs?

    This is lunacy.
