Readers!

 

It is now July, time once again to celebrate the start of this webpage in 2010 with my annual July fund-raising campaign.

 

This year I celebrate the fifteenth anniversary since I began Behind the Black. During that time I have done more than 33,000 posts, mostly covering the global space industry and the related planetary and astronomical science that comes from it. Along the way I have also felt compelled as a free American citizen to regularly post my thoughts on the politics and culture of the time, partly because I think it is important for free Americans to do so, and partly because those politics and that culture have a direct impact on the future of our civilization and its on-going efforts to explore and eventually colonize the solar system.

 

You can’t understand one without understanding the other.

 

Please consider supporting my work here at Behind the Black. Your help allows me to do this kind of intelligent independent analysis you don’t find elsewhere. I take no advertising or sponsors, so my reporting isn’t influenced by donations by established companies or political movements. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.

 

You can support me either by giving a one-time contribution or a regular subscription. There are four 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.
 

3. A Paypal Donation or subscription:

 

4. Donate by check, payable to Robert Zimmerman and mailed to

More SLS launches planned/proposed?

According to this article from Ars Technica, NASA is considering shifting gears in its Artemis lunar program to become more dependent on SLS rather than a mix of SLS and commercial rockets.

The new plan, if implemented, would substantially cut commercially developed rockets—such as SpaceX’s Falcon Heavy and Blue Origin’s New Glenn—back from the Artemis program. Previously, NASA had said it would launch elements of its Human Landing System on commercial rockets, because such vehicles cost much less than the estimated $2 billion rate per launch of the SLS vehicle. Now, perhaps, private rockets may be called upon to launch smaller pieces such as a lunar rover to the Moon’s surface.

The source document, which appears to be very preliminary and which NASA calls “inaccurate”, also calls for four SLS launches leading up to the 2024 lunar landing, something that seems very very unlikely. Not only would it require Boeing to move faster in building additional SLS rockets, something the company has routinely been unable to do, this schedule assumes funding from Congress for SLS, something that remains unclear.

It also appears from the proposed launch schedule that Lunar Gateway is fading from view. This makes great sense, as the Gateway only causes delays and higher costs for any lunar landing program, something the Trump administration clearly wishes to avoid.

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. from any other book seller, or direct from my ebook publisher, ebookit. 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

    Notice that it also relies on the Block 1B and Block 2 versions of SLS being in use in 2024 and 2028, respectively. Neither of which have received significant funding yet.

    While none of us here will lament the end of Gateway, a plan like this is a recipe for turning over NASA human spaceflight to Boeing, while not actually doing any exploration.

    …this schedule assumes funding from Congress for SLS, something that remains unclear.

    Oh, I think Congress will fund SLS just fine. It’s funding for the other mission elements I’m worried about.

    While none of us here will lament the end of Gateway…

    I will. Sure, you don’t need Gateway for a one-off flags-and-footprints mission. But it is Gateway that will lead to a robust re-usable lunar architecture.

    Nonetheless, I look forward to the release of the final plan.

    I have not been swayed either way yet on Gateway. A lunar space station intrigues me. As an amateur astronomer, it will have great views when I’m the far side. But I would think a lunar cycler would be just as effective in the states role.

    Build a vessel that makes the transit once. Let it bounce back and forth each time from LEO to Lunar insertion, and so on. Just refuel, swap crews/ equipment, and go.

    Side note : a gateway station would provide a communication link to any landers we put on the far side. I always thought an unmanned observatory on the far side, using either or both optical and radio telescopes would have great success.

    My tablet virtual keyboard aweful.

    I meant stated role, not states role.

    Gateway may not be in an optimal orbit for supporting lunar activity or even for supporting solar system traffic. Most likely it is intended to be in an orbit that is a compromise between what we think these two activities will need. It is almost certainly suboptimal for either.

    What we are missing is the knowledge of what orbit is best for the lunar sites that we will use most. We also are missing knowledge of what orbit will best support translunar exploration. We also do not yet know what resources on board our orbital stations will best support these missions and explorations.

    Gateway is too early to be useful and may not be thought out well enough to ever be truly useful.
