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.


Webb successfully inserted in final orbital position at the Sun-Earth Lagrange point

The James Webb Space Telescope today successfully completed a five minute firing of its engines to place it at the Sun-Earth Lagrange point dubbed L2.

Webb’s orbit will allow it a wide view of the cosmos at any given moment, as well as the opportunity for its telescope optics and scientific instruments to get cold enough to function and perform optimal science. Webb has used as little propellant as possible for course corrections while it travels out to the realm of L2, to leave as much remaining propellant as possible for Webb’s ordinary operations over its lifetime: station-keeping (small adjustments to keep Webb in its desired orbit) and momentum unloading (to counteract the effects of solar radiation pressure on the huge sunshield).

Engineers will spend the next three months aligning the segments of Webb’s large primary and secondary mirrors, while they wait for the telescope to cool down to the ambient very cold temperatures required for it to detect the tiny infrared heat emissions from very faint very very very distant objects.

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

  • Michael McNeil: Thank you. Fixed.

    For some reason I always thought Webb was going to the L4 since its stable orbit. The L2 point is unstable thus needing to use fuel to stay in that orbit. I hope they spent a little bit of time thinking about refueling mission during the 15 years they were working on this thing. Be nice to add a decade or more onto the life of this by just dumping in another tank of gas =)

    I gotta be a little bit proud here of our arian launch system accuracy… ( As a European..) apparently the accuracy of the launch has enabled an extra 5 years of propellant.
    I’m just over the moon that the thing is in place, seems to be working just as planned, and I’m looking forward to first light. As our host has mentioned once or twice… It’s no replacement for Hubble, but by God I’m looking forward to seeing how the universe looked a few hundreds of million years after first light…
    Any bets that it’s stranger than we ever imagined?

    Sayomara, NASA has a Q&A that discusses Webb and the orbit. Since the thrusters have to be on the sun side of the shield, they will always be drifting towards the sun. If they ever cross the divide and start drifting away, mission over. They also have to have a wide orbit of L2 so the Earth doesn’t block the sun from powering the arrays.

    I can’t wait for the thing to find the faint heat that has to radiate from alien megastructures ; )

    I made a similar comment on the Pluto post above, but for those avoiding the Pluto debate, I’ll repeat it here.

    The JWST is at L2, so NASA needs to manage the Webb’s orbit.
    And while L2 is defined as a non-stable Lagrange point, it is not very unstable, and takes relatively little effort to stay near L2.

    Can anyone explain what makes non-stable Lagrange points Very Unstable?

    A lucid explanation into the whole exercise of the Webb being put into an around L2 of Sun & Earth!

    Thanks Questioner- excellent informative video!
