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

Curiosity’s way forward

Panorama with balanced rock

As Curiosity moves up into the foothills of Mount Sharp the terrain is getting increasingly interesting. The image above is a panorama I have created from three Left Navigation Camera images posted here on Sunday evening. It shows what I think will be the general direction mission scientists wish to send Curiosity. (Note that the top of the leftmost mesa is not as flat as shown, as its top was cut off in the original image.)

Below is a Mars Reconnaissance Orbiter image showing Curiosity’s present position from above. I have annotated it to show the general view as shown in the above image. I have also marked on both the location of the balanced rock first photographed on July 7.

Orbital view of Curiosity's position

To get a sense of scale, note that the approximate distances of Curiosity’s last two drives, indicated by the yellow dots, is approximately 80 feet.

It appears to me that they are searching for the best route through and between the mesas that can be seen in the distance to the southwest. The peak of Mount Sharp is to the south, so heading in that direction makes some sense. From what I can tell looking at the orbital image, the best route in that direction seems to take them through the gap that contains the balanced rock. though they may decide that all of this terrain is too rough, forcing them to send Curiosity around to the north and west. Heading to the east of the mesas appears to be a less appealing choice because it puts them too close to some sand dunes that they have been skirting.

If they do go through one of those gaps, however, the journey should get very very interesting, with some very cool images along the way.

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
