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.


Primary data relay electronics unit on ISS truss fails

ISS managers are meeting to make a plan to deal with the failure on Saturday of the #1 data relay electronics box on the S0 truss of the station.

The unit, called an MDM, has an identical backup in place so no station operations have so far been effected. However, that backup had failed back in 2014 and required a spacewalk to replace it, so it is not clear to me as yet whether the station has any additional spares available to replace the newly failed unit. If so, it will still require a spacewalk to make the switch.

If there is no spare, they will likely have to ship one up on the next cargo flight, as the MDM is essential for operating the solar panels and radiators as well as the robot arms.

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

    Looks like the CRS-11 trunk is going to get an extra piece of payload. Hope the Dragon isn’t too near it’s mass or volume limit to overly complicate a sudden addition to its manifest, but if anything has to get bumped, that’s life.

    Convenient that this failure happens just before a scheduled resupply mission and not just afterwards.

    Mmmm, I seem to remember commenting about the startling lack of spare parts back when the 2014 failure occurred. Seems nothing’s changed.

  • Gealon: It appears you did not notice the more recent post on BtB, noting that they have the spare part and are doing a spacewalk today to install it.

    It would appear you are correct good sir, I had not refreshed the page since the day before I believe. Though I think my original comment still stands, they only have the one spare aboard yes? If this were the true interplanetary spacecraft testbed it’s supposed to be, the station should have a more generalized construction where, as it was stated in the later topic, boards can just be swapped out. At the very least have more then a single spare part if it’s so critical. Perhaps, as it was mentioned in the other topic, having a chip fab aboard would assist in the replacement of malfunctioning hardware. As I recall there is a 3D printer aboard the station but that is for strictly mechanical parts, and ones made out of plastic at that.

    Spare parts is an interesting topic. There is not a lot of space to store spare parts, and they are expensive to deliver, taking up, on the resupply ships, space and weight that could be used for productive items. So a question is: what parts are important enough, urgent enough, and subject to failure enough so that one or more spares are needed on board?

    ISS logistics must be quite an interesting job to have.
