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.


Cassini makes last fly-by of Titan

Cassini on April 21 made its last fly-by of Titan as the spacecraft is prepared for its final 22 orbits of Saturn.

The flyby also put Cassini on course for its dramatic last act, known as the Grand Finale. As the spacecraft passed over Titan, the moon’s gravity bent its path, reshaping the robotic probe’s orbit slightly so that instead of passing just outside Saturn’s main rings, Cassini will begin a series of 22 dives between the rings and the planet on April 26. The mission will conclude with a science-rich plunge into Saturn’s atmosphere on Sept. 15. “With this flyby we’re committed to the Grand Finale,” said Earl Maize, Cassini project manager at JPL. “The spacecraft is now on a ballistic path, so that even if we were to forgo future small course adjustments using thrusters, we would still enter Saturn’s atmosphere on Sept. 15 no matter what.”

The flyby zipped past Titan only a little more than 600 miles above its surface.

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

    Goodbye to a superb mission. I wish they could have done a dive thru the rings to see it close up.

  • mpthompson

    Orion314, that would have been cool. Imagine a probe that would orbit beyond the rings and then slowly lower its orbital height until it could dance among the snowballs that comprise the ring material.

  • Orion314: Read the article that I linked to. They will be making multiple dives through the rings during these final months.

  • Joe

    This is the kind of science and type of mission that NASA is good at, building giant rockets(Sls) not so much.

    Bob,
    re: “between the rings” I read that to be through the Cassini Division , or inside the the C ring and Saturn > I thought JPL/NASA was dead set against any actual ring impact for fear of possible satellite contamination.

    @Orion314
    The rings, those visible with binoculars from Earth, are fantastically thin, only about 10 meters thick!
    About 3% of the rings’ volume is mass. If the spacecraft covers one square meter, a dive through the rings would hit 30 liters of ice the in the 1,000 liters (10x1x1 meters) of ring volume it would pass through. Throwing a bucket of ice on Cassini at several kilometers per second would certainly destroy it. Cassini will not get close enough to resolve any of the ring particles, they are too small from a safe distance. A close up mission to the rings would be more like a surface lander on a microgravity asteroid. Landing on the protected trailing side one of the tiny shepherd moons would be nice in order to have a close look at ring particles.

    Having a mission for a lander on one of the shepherding moons would be one helluva rendezvous !
