A global view of Vesta

3:32 pm

Vesta

The accumulating data from Dawn has now allowed scientists to compile a global picture of the varied surface makeup of the asteroid Vesta.

The colors were chosen to highlight differences in surface composition that are too subtle for the human eye to see. Scientists are still analyzing what some of the colors mean for the composition of the surface. But it is clear that the orange material thrown out from some impact craters is different from the surrounding surface material. Green shows the relative abundance of iron. Parts of the huge impact basin known as Rheasilvia in Vesta’s southern hemisphere, for instance, have areas with less iron than nearby areas.

It also makes for a very nice image of the giant asteroid.

Mars Odyssey put itself into safe mode on Friday when it detected problems with one of the three reaction wheels used to orient the spacecraft.

If this space probe goes down, it will make it more difficult to rely data back from Opportunity, now on the Martian surface, and Curiosity, due to land in two months.

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, 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 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

Cave exploration in the western mountains

I have only visited Nevada twice before, and those visits had been limited to the area around Las Vegas. Thus, my impression of the state had been similar to what most other people assume: a big ostentatious urban city surrounded by boring flat deserts.

Instead what I found is that Nevada is probably one of the most beautiful states in the nation. It has many mountain ranges, interspersed with wide flat valleys, a number of which have lakes or swampy areas because the water is trapped there, draining neither to the Pacific or Atlantic.

Yet, it is desert country. The limited amount of water means that the state is lightly populated, and the few farms or ranches that you pass actually act to amplify the feeling of emptiness. This is further enhanced by the frequent mountain ranges. Every time you cross over a range, you find yourself high in the air with a spectacular view of the vast valleys below.

The Forest Service job that I was part of this past week was focused on inventorying and surveying a number of known caves covering a large area in northeastern Nevada. The work had actually started several years earlier, so that this particular week was the final wrap up, mapping the last few known caves on the list while also ridge-walking several different canyons in an effort to find some new discoveries.

The North Carolina legislature has passed a bill that requires its coastal planning commission to ignore the accelerated sea level rise predictions of global warming scientists and instead use more conservative numbers.

The North Carolina legislature has passed a bill that requires its coastal planning commission to ignore the accelerated sea level rise predictions of global warming scientists and instead use more conservative numbers.

To put it another way, North Carolina has decided, for coastal planning purposes, to use the slower linear rise in sea level that can be extrapolated from the actual data that scientists have gathered for the past century, and not use the models pushed by the IPCC and other global warming scientists that predict an acceleration of sea level rise in the next century due to human-caused global warming.

This decision by North Carolina has happened because increasingly people of good conscience no longer believe anything the global warming activists in the climate field are telling them. These scientists either perpetuated scientific fraud to sell the idea of human-caused global-warming, or have been willing to whitewash the fraud of other scientists. Rather than listen to them, the North Carolina legislature has decided to interpret the data independently. The legislature might very well be wrong, but what else can they do? They certainly can’t trust the claims of the climate field.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount.

Unless they can find a buyer the United Kingdom will close down its 3.8 meter infrared UKIRT telescope on Mauna Kea in 2013.

Telescope for sale: Unless they can find a buyer the United Kingdom will close down its 3.8 meter infrared UKIRT telescope on Mauna Kea in 2013.

This is a tragedy. A 3.8 meter telescope is no slouch and can do amazing research. The problem is that all the available money in ground-based astronomy is now being eaten up by the construction of giant telescopes in the 20 to 40 meter range.

What astronomy needs are some wealthy philanthropists who would like to buy these mid-sized telescopes, put their names on it, and finance their operation. This is how most big telescopes were made possible before World War II.

Construction of the world’s largest ground-based telescope has been approved by the European Southern Observatory.

Construction of the world’s largest ground-based telescope has been approved by the European Southern Observatory.

No one should get too excited about this announcement. They still need to raise 90% of their funds to build it, and to do so they have to get agreements from the four member countries of the European Southern Observatory. It will be years, probably at least a decade, before this 40-meter truly gigantic telescope sees the light.

On the way home

We are right now driving between Las Vegas and Hoover Dam, and should be home late tonight. Thus, I should be able to resume blogging sometime tomorrow. I will also write up a description of my experiences this past week and post it tomorrow.

First day caving in Nevada

11:19 pm

It is late and I have to up at 5 am to head to another cave tomorrow, so there is no time to give a detailed update of what happened today

However, here is a quick summary. Our goal was to find and map a rarely visited and difficult to find cave. After four miles of hiking and a lot of wandering across some pretty spectacular mountainsides, we failed to find the cave. However, we did locate two other small caves, which we surveyed, and then, on the way back to the vehicles, discovered a previously unknown cave of some size with significant formations. This was quite exciting, as the cave was clearly virgin, never seen by humans before.

We hope to return to explore and map it later in the week. Once again, I will get to go where no one has ever gone before!

Tomorrow will probably be as long a day as today, so I probably will not be able to post a more detailed report until Saturday. Stay tuned.

Off to Nevada

5:00 am

Nevada

For the next seven days my daytime posting is going to be spotty, as I will be in some remote areas of Nevada working on an on-going Forest Service project to inventory and survey caves in an area in the northeastern area of the state. The project is mostly over, but as I have surveyed, sketched, and done the cartography for many eastern U.S. caves, the guy running the project asked if I would be interested in participating. Interested? I was thrilled.

Though we will be in a somewhat remote area, I still hope to post periodically during the week, not only about the usual topics but also about some of the caves we will have surveyed, some of which are rarely visited. I will also try to post some pictures of the spectacular country we expect to visit. (The photo on the right was provided to me by Tom Gilleland, who is running the project.) Stay tuned.

Congressman Frank Wolf (R-Virginia) has backed down and modified the language he had inserted in the NASA budget bill that would have limited the number of commercial space companies NASA could subsidize.

Good news: Congressman Frank Wolf (R-Virginia) has backed down and modified the language he had inserted in the NASA budget bill that would have limited the number of commercial space companies NASA could subsidize.

From Clark Lindsey:

Rep. Frank Wolf (R-VA) , who is Chairman on the Commerce-Justice-Science subcommittee of the House Appropriations committee, put language into the recent House budget for NASA that requiree NASA to down-select immediately to one primary contractor in the commercial crew program. This would obviously eliminate competition on price and rule out redundancy in case one system is grounded. He has now relented and is willing to allow for “2.5 (two full and one partial) CCiCAP awards”.

As I wrote earlier, the success of Dragon is putting strong political pressure on Congress to support the independent commercial space companies over the NASA-built and very expensive Space Launch System (SLS) that Congress had mandated. Expect to see more elected officials back down in the coming year, with the eventually elimination of SLS from the budget.
