A quick holiday fund-raising campaign for Behind the Black!
 
Scroll down to read this post.
 
In past years I have managed to avoid asking for donations for Behind the Black during the holiday season. My finances however now compel me to do a short one-week fund-raiser, from November 11 to November 17.
 
I do not use Twitter for ethical reasons, which I have been told cuts down on traffic to the website. So be it. Furthermore, Facebook has clearly acted in the past two years to limit traffic to Behind the Black, almost certainly for political reasons. So be this as well. Finally, I do not post outside ads, as I have found them annoying to my readers and not that profitable to me.

 

Therefore, I need to ask for the direct support from my readers. If you like what I do here, please consider contributing, either by making a one-time donation or a monthly subscription, as indicated in the tip jar below.


 

Regular readers can support Behind The Black with a contribution via paypal:

Or with a subscription with regular donations from your Paypal or credit card account:


If Paypal doesn't work for you, you can support Behind The Black directly by sending your donation by check, payable to Robert Zimmerman, to

Or you could consider purchasing one of my books, as indicated in the boxes scattered throughout the website. My histories of space exploration are award-winning and are aimed for the general public. All are page-turners, and all not only tell the story of the beginning of the human exploration of space, they also help explain why we are where we are today. And I also have a science fiction book available, Pioneer, which tells its own exciting story while trying to predict what life in space will be like two hundred years in the future.

 

Note that for this week only I am also having a sale on the purchase of the last 20 hardbacks of Leaving Earth. (Click on the link for more information about the book, which was endorsed by Arthur C. Clarke himself!) This award-winning out-of-print book is now only available as an ebook, but I still have a handful of hardbacks available, normally for sale for $70 plus $5 shipping. For this week only you can buy them, personally autographed by me, for $50 plus $5 shipping! Just send me a check, payable to Robert Zimmerman, to the address above, with a note saying that the money is for the Leaving Earth hardback.

 

Please consider donating. Your help will make it possible for me to continue to be an independent reporter in the field of space, science, technology, and culture.

Route through Murray Buttes

After several days of drilling, the Curiosity science team is preparing to move forward. As one member of the team notes,

After a short drive we’ll acquire images for context and targeting. Overnight, Curiosity will complete a SAM electrical baseline test to monitor instrument health. Based on some of the recent Mastcam images that we’ve acquired…, the view ahead should be quite scenic as we drive through the Murray Buttes!

The image above is a close-up of those Buttes, showing Balanced Rock on the left, taken from one of three raw left navigation images. The image below is a panorama I have created from those navigation images, with an inset box to show the location of the above picture.

It appears, based on all of the images they have taken in the past day, Sol 1427, that they are trying to decide how to get around that small patch of dark sand directly ahead, and whether they can drive Curiosity through the gap in which the balanced rock is located.

Below is part of a Mars Reconnaissance Orbiter image, showing Curiosity’s most recent position and annotated by me to highlight the view from the panorama above as well as the location of the balanced rock (marked by the “X”). I have also indicated with a dotted line two possible routes. I suspect, unfortunately, that they are leaning towards the route to the west in order to avoid being forced to cross that dark sand in the eastern gap.

I also suspect that they are doing the short drive today in order to get a better idea of which way to go thereafter. Either way, the view will be quite interesting in the days ahead. Below is another section of the same Mars Reconnaissance Orbiter image, this time showing the rough terrain ahead to the south, surrounded by sharp buttes on all sides. Beyond this the ground appears to get even rougher. Picking Curiosity’s way through this terrain is going to become increasingly interesting in the coming days.

The way forward
