Update: Keith Cowing of SpaceRef reports that Sean O’Keefe and his son have survived the Alaskan plane crash today that killed former senator Ted Stevens.
Update: Thanks to commenter Ric who noted that Ted Stevens was not governor but senator. Too much travel and not enough sleep. I’ve corrected the webpage.

"Leaving Earth is one of the best and certainly the most comprehensive summary of our drive into space that I have ever read. It will be invaluable to future scholars because it will tell them how the next chapter of human history opened." -- Arthur C. Clarke
In an amazing illustration of what I call the great disconnect, AFL-CIO chief Richard Trumka blandly claims in this interview that the United States does “not have a deficit crisis.”
Spacevidcast has posted on YouTube as well as on their own webpage the first 10 minutes of a 20 minute interview with Elon Musk of SpaceX. You can see the full 20 miutes if you sign up for their Epic service.
For me, the interesting part of the interview is when he discusses the recent story about SpaceX’s plans to build a heavy-lift rocket, dubbed Falcon X. He explained that the proposal was not actually part of the company’s official plans. but the brainstorming ideas of one of the company’s engineers at an engineering conference. He also made it clear that he did not reject the idea. He likes giving his engineers the freedom to talk about such things publicly, even if the company is not yet ready to pursue them.
Watch the reaction of Democrat Bill Skaggs, the Kansas City mayor pro tem (1st district councilman) and former member of the State House of Representatives when he notices that he is being videotaped on this public street, then ask yourself if this is a reasonable reaction for an elected official.
A plane crash in Alaska with nine passengers included former Alaska senator Ted Stevens and former NASA administrator Sean O’Keefe. Though five deaths are reported, the identities of the dead and suvivors has not yet been releasted.
Two University of York researchers have identified the scribes who first made copies of some of English literatures most important early works. Key quote:
The discoveries were the result of painstaking research in the London Metropolitan Archives, where the York scholars matched the handwriting of scribes copying important early English literary manuscripts with the hands of Guildhall clerks copying documents and custumals.
Rising from the dead. The satellite phone company Iridium, once bankrupt, reports strong growth in sales and subscribers.
NASA engineers are working out a strategy for the next spacewalk, now tentatively scheduled of Wednesday, to continue repair efforts on the International Space Station. The new plans call for the astronauts to close several valves on the leaking coolant line while ground controllers lower pressure on the line, then drain the excess ammonia from it. This will hopefully allow the astronauts to disconnect the line from the pump without spewing ammonia all over the place, and then proceed with the removal of the failed pump.
An evening pause: From Kevin Branagh’s 1989 film of Shakespeare’s Henry V, the battle speech “upon Saint Crispin’s day”.
On August 6 former NASA administrator Mike Griffin bluntly attacked the Obama proposals for NASA in a speech at the 13th Annual International Mars Society convention in Dayton, Ohio, Key quotes:
We’re not going anywhere and we’re going to spend a lot of money doing it.
The US space program has not accomplished as much in its last 15 years as in its first 15 years, given more money. So, if you like that, you’ll really like the next decade, in which we do almost nothing and spend just as much.
Bureaucrats in space! The ministers of the African Union are proposing creating the African Space Agency to “focus on the development of common space policy for the continent .”
The efforts to fix the cooling system on ISS has not only limited use of the humans inside the station. It has delayed the maintenance work of the Canadian-built robot Dextre on the outside of the station.
A preprint paper [pdf] published today on the Los Alamos astro-ph website has found evidence that the oxygen and neon content of our Sun matches the abundances found in the galaxy. This result is important in that previous research has suggested that the Sun’s oxygen abundance was significantly higher than the rest of the galaxy, a possibility that not only caused problems for the theorists but raised interesting questions about the uniqueness of our solar system.
William Harwood of CBS News and Spaceflight Now provides a very detailed and clearly written description of the problems experienced during Saturday’s spacewalk, as well as the options faced by NASA to overcome them.
British engineers/scientists are about to send a robot into the Great Pyramid at Khufu in Egypt to find out what lies hidden behind the doors at the end of two 200 foot long shafts. Fun quote:
No one knows what the shafts are for. In 1992, a camera sent up the shaft leading from the south wall of the Queen’s Chamber discovered it was blocked after 60 metres [200 feet] by a limestone door with two copper handles. In 2002, a further expedition drilled through this door and revealed, 20 centimetres [8 inches] behind it, a second door.
“The second door is unlike the first. It looks as if it is screening or covering something,” said Dr Zahi Hawass, the head of the Supreme Council who is in charge of the expedition. The north shaft bends by 45 degrees after 18 metres [60 feet] but, after 60 metres, is also blocked by a limestone door.
An evening pause: We talk a lot about the International Space Station. Why not take a tour? In this January 2009 video, part 1 of 4, astronaut Mike Finke starts us out at the docking port used by the shuttle and takes us through the Harmony and Kibo modules. Along the way he gives a great view out the port side of the station.
You can see the remaining parts of Mike’s tour by clicking through, or you can wait until I post them over the next week.
Data from the AIRS instrument on NASA’s Aqua satellite shows the dramatic increase in carbon monoxide in the atmosphere at 18,000 feet over Russia due to the wildfires there. Key quote from press release:
The concentration of carbon monoxide is continuing to grow. According to Aug. 4 NASA estimates, the smoke plume from the fires spans about 3,000 kilometers (1,860 miles) from east to west.
NASA said late yesterday that a third spacewalk will be needed to finish the replacement of the failed pump module in the station’s cooling system.
Using data from the Japanese lunar orbiter Kaguya, scientists have identified several locations near the Moon’s south pole that are in daylight from 86 to 94 percent of the time. Key quote from abstract:
The place receiving the most illumination (86% of the year) is located close to the rim of Shackleton crater at 88.74°S 124.5°E. However two other areas, less than 10 km apart from each other, are collectively lit for 94% of the year. We found that sites exist near the south pole that are continuously lit for several months during summer. We were also able to map the locations and durations of eclipse periods for these areas. Finally we analyzed the seasonal variations in lighting conditions, from summer to winter, for key areas near the south pole. We conclude that areas exist near the south pole that have illumination conditions that make them ideal candidates as future outpost sites. [emphasis mine]
Below is a composite close-up image of the rim of Shackleten crator that I assembled using this Lunar Reconnaissance image. The key quote from the full caption :
The full [Narrow Angle Camera] mosaic reveals a shelf on the southeast flank of the crater that is more than two kilometers across and perfectly suitable for a future landing. The extreme Sun angle gives the surface an exaggerated rough appearance, but if you look closely at this scale any area that is between the small craters might make a good landing site.
The first spacewalk to replace the failed pump module on ISS is finished, and it did not go as well as hoped. The astronauts had problems removing one of four cooling system ammonia lines to the old pump. They eventually succeeded, actually using a hammer to lightly tap the quick-disconnect latch free. They then had to seal an ammonia leak coming from the problematic line. These issues caused them to run out of time, preventing them from removing the old pump and installing the new one. It is expected they will pick up where they left off on the next spacewalk, presently scheduled for Wednesday.
Yesterday a sheriff’s deputy from Prince George’s County, Maryland, shot and killed a family dog while trying to serve an eviction notice. This comes two years after a mistaken raid by Prince George’s police of the home of the mayor of Berwyn Heights killed his two dogs. Key quote:
[Mayor] Calvo, who is suing Sheriff Michael A. Jackson, alleging his deputies engaged in excessive force when they killed his dogs, said deputies have shown a disturbing propensity to kill family pets. “This is part of a pattern,” Calvo said. From 2005 to 2008, deputies shot at least nine dogs in eight incidents, according to sheriff’s department records.
The real horror of this story for those of us who live in Prince George’s County and own dogs (as I do) is that Michael Jackson is running for county executive, and in some polls, is leading the pack.
