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

SpaceX launch of NASA exoplanet hunting telescope TESS scrubbed

SpaceX today scrubbed the launch of NASA’s TESS space telescope, designed to look for transiting exoplanets orbiting the sky’s brightest stars.

The reasons for the scrub have not yet been announced, but the company says it is aiming for a new launch date on April 18.

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

    Stand down was due to “conducting additional GNC analysis.”, according to the tweeter.

    Speaking of the tweeters, Elon Musk threw these teases out on the 15th.

    “This is gonna sound crazy, but …”
    “SpaceX will try to bring rocket upper stage back from orbital velocity using a giant party balloon”
    “And then land on a bouncy house”

    It sounds to me that they are going to attempt reentry with a ballute, translate to a gps guided parachute and attempt to land on a field of airbags (ala “The Fall Guy”). A fairly low-mass reentry method, but risky.

    It’s worth noting that Mr. Musk didn’t indicate when the first upper stage recovery attempt will be, but it will certainly not be with TESS, where the upper stage will conduct a post-separation disposal burn putting it into a hyperbolic trajectory which will escape Earth orbit and enter an Earth-crossing heliocentric orbit.
