Comet hit Neptune 200 years ago
Astronomers have concluded that the high levels of carbon monoxide that they have detected in the upper layers of Neptune’s atmosphere are the leftover fingerprint of a cometary impact some 200 years ago.
Jackie Gleason and Frank Fontaine
An evening pause: In the 1960s, the Jackie Gleason Show was one of television’s most popular variety shows. Each episode had one regular routine, where Gleason played Joe the bartender, visited by an unseen Mr. Dunnaghy. Invariably, Joe would bring out his friend, Crazy Guggenheim, played by Frank Fontaine. Fontaine, as Crazy, would then hold everyone spellbound for five plus minutes with the most silly charactor humor one can imagine.
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 or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. 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
Solar powered plane flies for two weeks
Zephr, a British-built solar-powered unmanned plane was ordered to return to Earth after flying continuously for two weeks without refueling. Key quote:
Zephyr is set to be credited with a new world endurance record (336 hours, 24 minutes) for an unmanned, un-refuelled aircraft – provided a representative of the world air sports federation, who was present at Yuma, is satisfied its rules have been followed properly.
An ice-free Arctic in 10 years?
In today’s version of global warming fear-mongering, Senator John Kerry (D-Massachusetts) declared that the Arctic will be ice-free in “five or 10 years.” He apparently based this statement on a 2009 Geophysical Research Letters paper [pdf] that, using computer models, predicted an ice-free Arctic in September could occur as soon as the late 2020s but was more likely in the late 2030s.
Wanna bet? Since that 2009 paper was published, Arctic ice has seen a rebound in ice extent. Moreover, the Arctic oscillation remains in the deepest freeze it has seen in years. And the sun remains quiet, less active than we have seen it since scientists began tracking its behavior from space. Such inactivity means a dimmer sun, which in turn brings with it cold temperatures. Here is the most recent graph (updated on July 20) from the Total Solar Irradiance Time Series produced by Physikalisch- Meteorologisches Observatorium Davos (PMOD) using satellite data since 1978:
Even though the sun’s total irradiance has shown an up-tick recently as it slowly moves from solar minimum towards solar maximum, if you look closely you will see this up-tick still remains below the lowest points for the previous three solar minimums. And as I have noted here, we appear to be heading for the weakest solar maximum in two centuries.
Of course (as stock brokers say), the past performance of all of these trends is no guarantee of the future performance. Nonetheless, the data indicates clearly the simplistic nature of statements like Kerry’s.
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 the Mars Society.

Spudis on caves
On the subject of caves on the Moon, Paul Spudis has directed me to his very cogent October 2009 post for Air & Space magazine. Here he notes correctly that though lava tube caves on the Moon have value, they are unfortunately apparently not located in the best places for settlement.
Sunset on the Moon
As the sun sets on Bhabha crater on the Moon’s farside, small boulders on the crater’s central peaks become visible in this Lunar Reconnaissance Orbiter image, with inset below. (It is very worthwhile to click on the link above and stroll through the full resolution image.) Scientists believe that the impact which created this crater excavated these boulders from deep within the Moon’s crust, thereby making them valuable tools for determining the geological history of the Moon. Of course, to use these tools requires the geologist to be there, something that might not happen for a while.

Worries about JWST
Keith Cowing at NasaWatch notes quickly that the current budget battles over NASA have people in NASA concerned about the future of the James Webb Space Telescope. The telescope has further cost overruns, and should NASA end up operating under a continuing resolution rather than a full budget, there won’t be enough money to keep the project above water.
New currency symbol for India
This Slate article not only describes the new symbol India has chosen for its currency, it also gives a nice thumbnail description of the origins of other currency symbols, such as the U.S. dollar sign and the English pound sign.
Impact crater in Egypt
Using Google Earth, a curator at an Italian museum has discovered a previously unknown, very young, and almost pristine impact crater hidden in the deserts of Egypt.
Space war update
This Orlando Sentinel analysis of the various Congressional NASA budget proposals working their way through the House and Senate right now concludes, as I have been saying for months, that the future for NASA is not good. Key quote:
The plan orders NASA to build a heavy-lift rocket and capsule capable of reaching the International Space Station by 2016. But it budgets less money for the new spacecraft — about $11 billion during three years, with $3 billion next year — than what the troubled Constellation program would have received. That — plus the short deadline — has set off alarms.
Swallowing a planet
A star with an appetite: Astronomers have used the Chandra X-Ray Observatory to take a closer look at an engimatic star in the constellation Pisces and found that the dust cloud that surrounds it as well as the unusual and enormous jets that shoot from it probably originated when the star evolved, expanded, and swallowed an orbiting companion, either a giant planet or companion star.
Journolist scandal-Tucker Carlson editorial
Tucker Carlson, the editor-in-chief of the Daily Caller, has written a lengthy essay on his organization’s series on the scandal surrounding the defunct liberbal Journolist listserv. Key quote:
We’re not contesting the right of anyone, journalist or not, to have political opinions. (I, for one, have made a pretty good living expressing mine.) What we object to is partisanship, which is by its nature dishonest, a species of intellectual corruption. Again and again, we discovered members of Journolist working to coordinate talking points on behalf of Democratic politicians, principally Barack Obama. That is not journalism, and those who engage in it are not journalists. They should stop pretending to be. The news organizations they work for should stop pretending, too.
Read it all.
Tell me on a Sunday
An evening pause: Sarah Brightman again, this time singing “Tell me on a Sunday,” a lovely song from the musical Song & Dance.
House committee adds extra shuttle flight
The space war continues. The House Committee of Science and Technology has amended its budget proposal to include an extra shuttle flight, making its proposal match the Senate’s proposal in at least this one way.
Russians reveal new spacecraft
The Russians unveiled today a new proposed replacement for their Soyuz capsule, capable of carrying six astronauts into orbit. Interestingly, the design does not use parachutes to land, but solid rocket engines.

Exploring Mars from Earth
Want to poke around on Mars? Since it might be a while before you can actually go there, I suggest you instead make frequent visits to the images page for the HiRise camera on Mars Reconnaissance Orbiter. The pictures that appear here are routinely breath-taking. Below is a cropped image showing the flat top of a mesa in Coprates Chasma. The full image shows detailed layers down the side of the mesa as well as rippled dunes on the mesa top. Everything is remarkably reminescent of something you’d see if you visited the Grand Canyon. Only on Mars, this grand canyon is many times larger and deeper.
