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 the Mars Society.

An update on the ongoing X-37B mission
An update on the ongoing X-37B mission.
I like this quote from the article:
Meanwhile, Boeing has begun to look at derivatives of their X-37B Orbital Test Vehicle — including flying cargo and crew to the International Space Station. Speaking this week at the Space 2011 conference —organized by the American Institute of Aeronautics and Astronautics (AIAA) and held in Long Beach, Calif. — Arthur Grantz of Boeing Space and Intelligence Systems sketched out a host of future uses for the space plane design. For one, the X-37B, as is, can be flown to the space station and dock to the facility’s common berthing mechanism. No new technology is required for X-37B to supply cargo services to the ISS, Grantz said. Also, an X-37C winged vehicle has been scoped out, a craft that would ride atop an Atlas 5 in un-shrouded mode.
The Boeing roadmap, Grantz added, also envisions a larger derivative of the X-37B space plane, one that can carry up to seven astronauts, as well as tote into Earth orbit a mix of pressurized and unpressurized cargo.

The strange hollows on the mountain tops of Mercury
Another spectacular planetary science image, this time from Messenger orbiting Mercury. This close-up image of the hollows of Mercury only illustrates their mystery. The insert shows the context of the close-up image. These irregular sinks are here found on the mountain top ridge of an inner crater rim. Also, some but not all of the hollows have bright interiors.
Scientists have proposed that some form of impact melt process caused these hollows. At impact, the ground literally rippled like water when you toss a stone into a pool. Here, however, the molten ripples quickly froze, creating the inner and outer crater rim rings. To my untrained eye, the hollows look like collapse features where the surface hardened first, then collapsed when the molten inner material drained away as it became solid.
Why some hollows are bright, however, is not yet understood.
Dawn begins close-up orbit observations
Dawn begins close-up orbit observations of Vesta. More new results here.
In this orbit, the average distance from the spacecraft to the Vesta surface is 420 miles (680 kilometers), which is four times closer than the previous survey orbit.

The red cliffs of Mars
Last week the Mars Reconnaissance Orbiter team released this beautiful image of what they call “layered yardangs” on Mars.
What creates these sharp ridges? This layered terrain has been sculpted by the wind. The aligned ridges are called yardangs, which are formed in areas where the dominant erosional force is the wind. Yardangs are also found on Earth, usually in very dry areas.
What I see are majestic red cliffs rising out of a aqua-colored sand desert. What a place to visit!

Test flights of SpaceShipTwo resume
After a summer break, the flight tests of SpaceShipTwo have resumed. Thursday’s test appeared to a bit more exciting that previous flights:
Test card called for releasing the Spaceship from WhiteKnightTwo and immediately entering a rapid descent. Upon release, the Spaceship experienced a downward pitch rate that caused a stall of the tails. The crew followed procedure, selecting the feather mode to revert to a benign condition. The crew then defeathered and had a nominal return to base. Great flying by the team and good demo of feather system.

Scientist proposes that the superluminal neutrinos are merely measuring the true speed of light
On Thursday physicist Susan Gardner of the University of Kentucky proposed in a preprint on the Los Alamos astro-ph website that the neutrinos measured at CERN that appeared to be going faster than light were merely giving us a much more accurate measure of the speed of light.
This is only one of a plethora of papers published this last week on astro-ph discussing and attacking the CERN neutrino results. I expect the scientists will solve this mystery before too long.

Arctic ozone loss at record level
The ozone levels over the Arctic this past year were the lowest on record, caused by unusually cold temperatures.
No records for low temperature were set this year, but the air remained at its coldest for an unusually long period of time, and covered an unusually large area. In addition, the polar vortex was stronger than usual. Here, winds circulate around the edge of the Arctic region, somewhat isolating it from the main world weather systems.
“Why [all this] occurred will take years of detailed study,” said Dr. [Michelle] Santee [from NASA’s Jet Propulsion Laboratory]. “It was continuously cold from December through April, and that has never happened before in the Arctic in the instrumental record.”

Santa Catalina Mountains – hike to Romero Pools
An evening pause: A hike to Romero Pools in the Santa Catalina Mountains just outside Tucson, Arizona. The hiker in the video calls this one of the toughest hikes he’s ever done, but it is only 5.6 miles round trip, with only a thousand foot elevation gain. Compared to most of the other Santa Catalina hikes, which routinely require elevation gains of 3000 to 5000 feet, this one is easy.

Russia launches its first Soyuz rocket since the Progress launch failure in August.
This was a launch of a Soyuz-2 rocket, which is not identical to the Soyuz-U rocket that the Progress freighter was on. Nonetheless, the success is a good sign that they are back in business.

Five myths about China’s space effort
Five myths about China’s space effort. Key recommendation:
Recognize the significance of space as a field of competition. Beijing is not engaged in a space race with Washington. But China is engaged in a great power competition with the U.S. in which space is one arena. American decision makers should come to terms with this duality. In this regard, the Chinese are unlikely to be manipulated by American proposals on “codes of conduct” or meetings with the head of NASA. As long as Beijing and Washington are in competition, space will be one of the major venues.
And competition is not a bad thing. It is going to be the fuel that gets the human race into space.

Obama administration considering eliminating the ATF
Whoa! The Obama administration is considering eliminating the ATF in connection with the guns-to-Mexico scandal.
After a town hall meeting about Operation Fast and Furious in Tucson, Ariz. on Monday, ATF Whistleblower Vince Cefalu, who has been key in exposing details about Operation Fast and Furious, confirmed the elimination of ATF has been circulating as a serious idea for sometime now and that a white paper outlining the plan does exist.
[snip]
[However,] ATF field agents weren’t the problem with Operation Fast and Furious, high ranking officials within ATF and the Department of Justice were and still are. DOJ would eliminate ATF only to take the heat off of the Obama Administration. By eliminating the bureau, it makes it seem like DOJ is taking Operation Fast and Furious so seriously, they decided to “clear out the corruption, clean house,” however, it would only be a distraction away from the people at the top of the investigation. In fact, evidence shows the DOJ has been stonewalling the Oversight Committee investigation into the operation to protect Obama political appointees.
If true, this story suggests that there are many very high level officials in the Obama administration that are very vulnerable to prosecution over Operation Fast and Furious, and they are scrambling to find a way to protect themselves anyway possible.

Mars atmosphere has more water vapor than predicted
Data from Mars Express has found that the Martian upper atmosphere has far more water vapor than predicted.
“The vertical distribution of water vapour is a key factor in the study of Mars’ hydrological cycle, and the old paradigm that it is mainly controlled by saturation physics now needs to be revised,” said Luca Maltagliati [of the Laboratoire Atmosphères, Milieux, Observations Spatiales (LATMOS) in Guyancourt, France]. “Our finding has major implications for understanding the planet’s global climate and the transport of water from one hemisphere to the other.”
“The data suggest that much more water vapour is being carried high enough in the atmosphere to be affected by photodissociation,” added Franck Montmessin, also from LATMOS, who is the Principal Investigator for SPICAM and a co-author of the paper. “Solar radiation can split the water molecules into oxygen and hydrogen atoms, which can then escape into space. This has implications for the rate at which water has been lost from the planet and for the long-term evolution of the Martian surface and atmosphere.”
