Japanese scientists have detected minute particles in the Hayabusa capsule! Whether these particles are from the asteroid or not remains unknown.
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.
"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
The press finally notices the absurdities of Obama’s new space policy, something I have been talking about for months, and noted again earlier this week.
Saturday’s weekly dump of publications from the American Geophysical Union also included a paper that showed visual proof of avalanches on Mars! In this case, the location is Russell Crater, “a large crater in the southern hemisphere that exposes a large dune field in its center.” The avalanches occur because a frost layer made up of dry ice and a little bit of frozen water builds up on the crest of the dunes. When that frost melts, dark streaks about three to six feet wide and about 150 feet long appear, flowing downhill. The scientists believe these are avalanches made up of “a mixing of sand, dust, and unstable CO2 gas.”
Before and after shots of the dark streaks flowing down the dune.

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.
“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.

A very long (182 pages) and detailed preprint paper was published today on the Los Alamos astro-ph website, describing the completion of a survey of just about all the sunlike stars within approximately 82 light years of the Earth. I haven’t had time to read the whole thing, but the abstract made these notable points:
In other words, the evidence continues to suggest that solar systems like ours are very common.
I haven’t been posting that much this weekend because I’ve been very busy, doing American July 4th types of things: mainly guns and fireworks! On Saturday, I went to the 12th Precinct Pistol and Archery Club for the range’s twice weekly bullseye target pistol league competition. Shot a pretty good 817 out of 900 with my 22 caliber pistol, and a mediocre 733 with my 45.

After its docking failure Friday, the Russian unmanned Progress freighter successfully docked with ISS today.
For those who fantasize that Mars might still have vast underground lakes with fish, the recent data is unfortunately not encouraging. A paper published today by the American Geophysical Union suggests that if groundwater exists on Mars, it is going to be increasingly difficult to find, possibly only in the low latitudes at low elevations. These paragraphs from the conclusion of the paper say it all:
Various lines of evidence suggest that at the time of the Late Hesperian, Mars possessed a planetary inventory of water equal to a global ocean ~0.5 km deep, much of which is believed to have been stored as ground ice and groundwater in the subsurface. The potential survival of groundwater to the present-day has important implications for understanding the geological, hydrological and mineralogical evolution of the planet, as well as the potential survival of native Martian life. The two most important factors affecting the persistence of groundwater on Mars are the depth and pore volume of the cryosphere.
To date, the orbital radar sounding data from MARSIS [an instrument on Mars Orbital Express] has provided little evidence of any deep reflectors potentially indicative of subpermafrost groundwater. Here we have examined two (of several) possible explanations for this lack of evidence: (1) that subpermafrost groundwater no longer survives on Mars or (2) that groundwater is present, but that a thicker than expected cryosphere has restricted its occurrence to depths that exceed the estimated ~3 km maximum sounding depth of MARSIS.
[snip]
Which one (or combination) of explanations discussed here is responsible for the lack of deep reflectors on Mars is unknown. But our revised estimates of cryosphere depth suggest that a successful detection of subpermafrost groundwater, outside of those areas on Mars that combine low latitude and low elevation, is unlikely. In an effort to better constrain this problem, a more comprehensive investigation of the MARSIS sounding data obtained over Athabasca Valles, and four other low-elevation, near-equatorial sites, is currently underway.
Tonight, from 9 pm to 1 am (EDT), I will be on the John Batchelor Show. John is off tonight, so the guest host is Simon Constable, with yours truly acting as his co-host. For my part, I’ve arranged four guests:
Then I have brought in three guests to talk about the Obama administration’s new space policy and the space war developing between the administration and Congress over the administration’s effort to cancel the Constellation program:
Each will have his own 15 minute segment to express his views. Should be a fun time tonight.
I just thought I’d note the interesting juxtaposition illustrated by my previous two posts: In one case there is a battle between Congress and the President over the future of the American manned space program, prompted by the impending shutdown of the shuttle program with no immediate replacement in sight. In the other case, the only remaining program with the capability to provide manned access to the International Space Station has a serious docking failure.
With manned spaceflight, redundancy is all important. This juxtaposition illustrates very clearly the precarious position we will be in once the shuttle is retired.
The political space war continues. The Senate Commerce Committee is going to propose on July 15 one extra shuttle flight and the immediate move to develop a “heavy-lift” rocket (which is merely another name for the Ares rocket).
The arrival of a new unmanned Progress freighter at ISS has gone wrong, with the freighter drifting past the station by several miles. What happened is not yet clear, but as far as I know from my research into the Russian space station program, this is the first time the automatic docking of a Progress freighter has failed this wildly. There have been some near collisions, but to miss by miles is unprecedented.
Whether they can redirect the freighter back to the station also remains as yet unknown.

The Penn State University investigation report on Michael Mann might be a whitewash, but what is really a travesty is the way some so-called professional journalists have covered this story. First, go and read the these two news articles at the New York Times and the Washington Post. I’ll wait till you’re back.
All done? Okay. Note how both news articles say very little about the report itself, other than its conclusions. Instead, the news articles follow the same boring news formula for writing these kinds of stories:
Neither news article provides the reader with the slightest analysis of the investigation report itself. Neither bothers to describe its superficial nature and its almost obsessive desire to find Michael Mann innocent.
Finally, both news articles read as if the reporters barely read the report itself and knew little about the content of the East Anglia emails. Instead, their stories read as if they simply scanned the press releases about the report and worked from those.
Another example of press release journalism at its worst.
Alan Boyle on his Cosmic Log webpage today has a nice report on astronaut photographer Douglas Wheelock and the spectacular pictures he is taking in his stint on ISS.
The investigation at Pennsylvania State University of Michael Mann and his behavior as revealed in the East Anglia emails was released today, clearing him of all but one minor charge. You can read the actually report here. I suggest you do, as you will be amazed by the absurdity of this so-called investigation.
First, the manner in which the university investigated and then cleared Mann of the main charges was a joke. The panel reviewed the East Anglia emails, then brought Mann in to answer questions. When he essentially told them he had done nothing wrong, they decided that was evidence enough, clearing him of three of the four main charges.
Then, on the one remaining minor charge, the sharing of other people’s unpublished manuscripts without permission, the panel brought in other scientists for independent opinions, though only one of which, Richard Lindzen, is a skeptic of Mann’s work. Lindzen’s reaction when he learned he was not being interviewed on any of the main charges is quite entertaining. To quote the report itself,
When told that the first three allegations against Dr. Mann were dismissed at the inquiry stage . . . Dr. Lindzen’s response was: “It’s thoroughly amazing. I mean these are issues that he explicitly stated in the emails. I’m wondering what’s going on?”
The Investigatory Committee members did not respond to Dr. Lindzen’s statement.
On this final charge, the committee decided only that Mann’s distribution without permission of other people’s unpublished manuscripts was “careless and inappropriate,” and then finished by essentially saying in very stern words: next time, ask first.
Not surprisingly, the New York Times report on the conclusions of the investigation is somewhat joyous.
Unfortunately, this whitewash will only do harm to the reputation of science and the modern scientific community, and will almost certainly increase the general public’s distrust of climate research (and the reporting of it by mainstream publications like the NY Times).
An evening pause: Julie Andrews, in her prime, had one of the most incredible screen presences of any actor in the history of film. Unfortunately, though everyone will agree that she has had a marvelous career, except for a few rare but truly wonderful exceptions (Mary Poppins, The Sound of Music) I have always felt that her amazing ability to mesmerize an audience with a mere look was generally wasted in most of the movies she made.
Here is Julie in the movie Star!, which did not do well when released because it came out at a time (1968) when filmgoers seemed uninterested in entertaining musicals. Movies then had to relevant (oh that word!). She is playing a young woman whose deepest passion is to perform on the stage. This scene is her first real chance to do something solo. Stay till the end. Her first words after the she leaves the stage says it all. Unfortunately the versions available now cut that last line, where she so sincerely says, “That was wonderful.”
Here is another example of why I remain skeptical of any claims that the science of global warming is settled. Ken Stewart, a retired school teacher in Australia, decided to make a very detailed comparison between the raw data and adjusted data of all thirteen weather stations in the state of Victoria, and found that, for unknown reasons, the adjusted “data [has] been arbitrarily adjusted to cool earlier years,” thereby creating the illusion that the region’s climate has been warming since the 1930s.
Take a look at the many graphs on his webpage. It will make you wonder.
Why I never use Wikipedia. Key quote:
The larger moral of this story is that Wikipedia itself is a fundamentally flawed and unreliable source. In fact, it is wrong even to describe — much less to use — Wikipedia as a source. Wikipedia is merely a platform. Since anyone and everyone can edit Wikipedia entries and since they can do so anonymously, Wikipedia is, by its very nature, susceptible to constant manipulation.
Mission operators at the Applied Physics Lab in Maryland did a 35 second course correction yesterday on the New Horizon’s mission to Pluto, increasing its velocity by one mile per hour. The planned fly-by now set for July 14, 2015.
A new picture of the Japanese solar sail Ikaros has been released, showing the sail in operation. By turning power on and off to different sections along the sail’s rim, engineers can change the way light reflects off those sections to control the sail’s attitude in space without using fuel. Note also that the power comes from sunlight, not from batteries. The picture below illustrates this, with different parts of the rim either bright or dark, depending on whether they are powered or not.
NASA has now made it official: they have set the dates for the last two shuttle flights, extending the program into late February 2011. Considering the dissatisfaction in Congress and with the public over the lack of any replacement for the shuttle, don’t be surprised if at least one more shuttle flight gets added to the schedule.
Want to get a sense of the subtleties and complexity of rocket engineering? Go to this Chris Bergin report at nasaspaceflight.com about the unusual number of visible streaks of light that were seen in the engine plume of the shuttle’s main engines during the last flight of Atlantis. Who would have thought this matters? It does.
Enough with depressing space news. Take a break and watch Andrew Klaven’s totally untrue but very silly analysis of how global warming broke up the Gore marriage.
And are we supposed to be happy? NASA is going to give the last shuttle external tank a send off ceremony when they roll it out for shipment by barge to the Cape on July 8.
Always remember: science is doubt! Since the 1970s, most oceanographers have favored the theory that past ice ages on Earth were caused by the switching on and off of a global ocean conveyor belt. Now, that decades-old theory is being questioned.
You can read it here, if you have a mind. It is filled with the typical go-gooder blather that you find in every policy statement produced by every politician and his or her policy wonks, from either party.
Nonetheless, the Obama policy is far different from the Bush policy. The Bush philosophy for NASA is probably best ipitomized by this speech by Mike Griffin, former NASA administrator during the Bush administration. The key quote:
I am convinced that leadership in the world of the 21st Century and beyond will go to the nation that seeks to fulfill the dreams of mankind. We know what motivates those dreams. Exploring new territory when it becomes possible to do so has defined human striving ever since our remote ancestors migrated out of the east African plains. The human imperative to explore new territories, and to exploit the resources of these territories, will surely be satisfied, by others if not by us. What the United States gains from a robust, focused program of human and robotic space exploration is the opportunity to define the course along which this human imperative will carry us.
In other words, the focus during the Bush years was to have the United States lead the way in exploring and colonizing the solar system, with NASA in charge.
The Obama philosophy in this new space policy is far less interested in exploration. Instead, the focus is on international cooperation and sharing the universe with everyone. Here is for me the key quote from the policy statement:
As established in international law, there shall be no national claims of sovereignty over outer space or any celestial bodies. The United States considers the space systems of all nations to have the rights of passage through, and conduct of operations in, space without interference. Purposeful interference with space systems, including supporting infrastruction, will be considered an infringement of a nation’s rights.
In other words, space is a communal farm, shared by everyone.
The sense I also get from reading the Obama policy is a focus not in pushing outward to explore the unknown, to go where no one has ever gone before, but on looking back at the Earth to make things on Earth better. Both the “Principles” and “Goals” as outlined in the Obama Policy (pages 2 and 3) say very little about exploration. Instead, the focus is on stimulating the world’s space industry in order to improve life on Earth. The proposal to send humans to an asteroid and eventually to Mars is listed near the end of the document, almost as an afterthought.
Some will like this new approach. Others will detest it. From my perspective, it is simply naive.
First of all, the fantasy that territory in space will remain communal property, unowned by any person or nation, is foolish. The space colonists who will go there to live are eventually going to tell us to go to hell, and will then set up their own nations — with property rights — if only to guarantee that they have the same rights that we here on Earth enjoy.
Second, the exploration of space is not being done to make life on Earth better. That is certainly a significant side benefit, but the people sweating to build new rockets and spaceships are not doing it for these reasons. They are doing it because they want to explore and colonize the solar system. And they are doing it because they want to make money at it.
In the end, the problem with establishing a policy that is not based on reality is that reality will eventually bite back. Just because the United States wants to play nice with everyone and share space with the rest of the world does not mean that the rest of the world will do the same. In fact, it almost guarantees that they won’t. Other nations are going to immediately try to fill the vacuum this Obama policy creates.
Unfortunately, for the near future things do not look good for the American effort in space.
Revised.
Though it has appeared that many if not most members of Congress have been unhappy with the Obama administration’s efforts to shut down the Constellation program, I have always believed that in the end, Congress wouldn’t have the fortitude to force its desires on the President. The action yesterday by the House appropriations subcommittee that funds NASA to take a neutral position on Obama’s proposals demonstrates this. They are willing to give NASA the extra money that Obama propopses, but they also have said that a compromise between Congress and the President on the future of the manned program must be agreed to before the money can be spent. See also this story in today’s Wall Street Journal.
In other words, the appropriations committee has passed the buck to the House Science and Technology committee. I expect that committee will find a way to pass the buck somehow as well. And if they don’t pass the buck, I suspect they will work out a compromise that on the surface will allow committee members to claim they “saved” NASA, but in reality will do nothing of the kind.
In the end, I believe the American government manned space program is going to die. Whether the new emerging private space industry can pick up the slack in today’s American Soviet-style bureaucratic society remains an unknown.
