ISS to be deorbited in 2020
The head of the Russian space agency said today that ISS will be deorbited in 2020, as agreed to by the governments running it.
Wanna bet? They are only now starting to do the research the station is best designed for, and learning how to live in space for years is going to take years. Come 2020, that work will hardly be done. Moreover, the impossibility of replacing ISS without a shuttle to haul up large modules and trusses will make very appealing the idea of keeping the present station in operation.
Then again, everything I just wrote is simple common sense, and who ever expected common sense from these governments?

ISS partners discuss how to use the space station as a test bed for missions beyond low Earth orbit.
Now why didn’t they think of this before? The ISS partners met today to discuss how to use the space station as a test bed for missions beyond low Earth orbit.
As I wrote in Leaving Earth, a space station is nothing more than a prototype interplanetary spaceship. This kind of research is really its main purpose, and I am glad that the governments running ISS are finally beginning to recognize it, even though their engineers have known it for decades. Note too that the press release above also gives a nice overview of some of the ongoing research on ISS that is directly related to learning how to survive in space for long periods.

Junk journalism
In a piece today at the Huffington Post, science journalist Seth Borenstein declares the wonders of NASA’s next mission: to send astronauts to an asteroid by 2025, as declared by President Obama.
If you believe this is going to happen, then I have a bridge I want to sell you. To do it we need a spaceship in which people can live for at least a year, and a rocket to get that ship into orbit. Not only do we not yet know how to build such a spaceship, we no longer have the capability of putting it into orbit. In case you’re unaware (Borenstein acts like he is), the space shuttle no longer exists. And under this administration and Congress, any replacement we get isn’t going to be able to launch such an interplanetary spaceship anywhere in the near future, especially faced as we are with the present federal debt.
The disgraceful thing about this article, however, is the lack of skepticism shown by Borenstein.

Public test of privately built moon lander delayed by gyro
A public test of privately built moon lander has been delayed by gyro problem. Key quote:
One customer has already bought a ticket with Moon Express, asking them to deposit a small telescope on the dark side of the Moon. Jain says the company will also offer low cost ways for anyone to use the moon as a kind of time capsule. “If something goes to the moon it stays there forever, people will pay to sends things like photos, or maybe your hair or DNA.”

NASA changes its contract arranged for commercial space
Turf war: At conference yesterday at the Johnson Space Center, NASA proposed changing how it issues its commercial space contracts so as to give it more control over their design and construction. The commercial companies are not happy.
Brett Alexander, a space industry consultant who counts among his clients the secretive aerospace startup Blue Origin of Kent, Wash., said at the July 20 briefing that industry needs to know NASA’s legal reasoning for dismissing SAAs as an option for the next CCDev round. “From an industry standpoint … we’re kind of flying blind because [NASA] has not divulged what its legal reasoning is, and I think they need to do that in writing. Not a couple charts, not things that you brief, but a legal brief that says ‘here’s why’” a traditional procurement is necessary.
My own sources say this change in contractual approach will significantly slow development of the new commercial manned space rockets and ships, possibly beyond 2017.
The only reason I can see for NASA to do this is to maintain control over manned space, even if they are not building anything. I think NASA is instead going to find out that doing anything to slow this development will be politically very dangerous for them.

A good summary of the present American manned space situation
Clark Lindsey has put together a very succinct but thorough summary of the present and future state of American manned space.
The bottom line is that the U.S. can easily have multiple rockets and spaceships to put people into space, in only a few short years, if only our government will get out of the way.

The journal Science finally admits things have not gotten warmer in the past decade
The journal Science finally admits things have not gotten warmer in the past decade.
The explanation provided, that recent volcanic eruptions cooled a warming earth, might be true, though the conclusions are based not so much on data but on climate computer models, a fact that leaves me somewhat skeptical. Nonetheless, what is significant to me about this article is that Science — which has been decidedly in the global warming political camp for years and has frequently lambasted scientists who suggested the climate’s warming has slowed or even stopped in the past decade — has now been forced to admit that the warming has stopped. That they feel compelled to push the global warming threat in the same sentence only reveals their continuing scientific bias.

Perry and other lawmakers blast Obama over shuttle retirement
Texas Governor Rick Perry, as well as other lawmakers from Congress, blasted Obama today over the shuttle retirement.
Bah. Perry claims to be a so-called small government conservative, yet he wants the government to spend a fortune to build and run the space program. Meanwhile, Senators John Cornyn (R-Texas) and Kate Bailey Hutchinson (R-Texas) were around in Congress when President George Bush announced the shuttle’s retirement seven years ago. Their effort since then to fund pork through NASA and thus have NASA build a giant new rocket system, either Constellation or its new Congressionally-designed replacement, has been a disaster. Right now it would be better, and far cheaper, if they stopped fighting the new commercial space companies and instead get behind them, especially since the Obama administration itself has done a very poor job of selling this new industry.
A little support from Congress could go a long way to not only reinvigorating the aerospace industry, it could speed our country’s return to manned space, with multiple competing companies.

A flag in the dust
Bumped: I posted this essay last July 20th on the anniversary of the Apollo 11 landing on the moon. I think it is worth rereading again, even as the shuttle is about to return to Earth for the last time.
Today, July 20th, is the anniversary of the Apollo 11 landing on the Moon, the first time ever that a human being arrived on another planet. Americans love to celebrate this event, as it symbolizes one of the finest moments in our history, when we set out to achieve something truly great and noble and succeeded far better than we could have imagined. Not only did we get to the Moon as promised, over the next three and a half years we sent another five missions, each with increasingly sophisticated equipment, each sent to explore some increasingly alien terrain. Forty-plus years later, no one has come close to matching this achievement, a fact that emphasizes how difficult it was for the United States to accomplish it.
There is one small but very important detail about the Apollo 11 mission, however, that most Americans are unaware of. In mounting the American flag, the astronauts found the lunar surface much harder than expected. They had a great deal of trouble getting the flagpole into the ground. As Andrew Chaikin wrote in his book, A Man on the Moon, “For a moment it seemed the flag would fall over in front of a worldwide audience, but at last the men managed to steady it.” Then Armstrong took what has become one of the world’s iconic images, that of Buzz Aldrin standing on the lunar surface saluting the flag of the United States of America.
What people don’t know, however, is that when Armstrong and Aldrin blasted off from the lunar surface, the blast wave from the Lunar Module’s rocket knocked the flag over. As Chaikin also wrote, “Outside, a spray of gold foil and debris from the descent stage flew away in all directions. The flag toppled to the dust.”
Thus, for the last four decades this American flag, shown so proudly unfurled on the surface of the Moon, has actually been lying unceremoniously on the ground, in the lunar dust.
It might actually be possible to see this, though the photos at this time remain unclear and quite blurry.

Russia vows not to exploit manned space flight monopoly
That’s so nice of them: Russia vows not to exploit its manned space flight monopoly.
Actually, this isn’t really news. Since the fall of the Soviet Union the Russians have always driven a hard bargain when they have sold tickets to get crew or cargo into space. However, once the contract has been signed they have also honored those contracts, to the letter. As the U.S. already has a signed contract to get its astronauts to ISS using Russian rockets and capsules, there won’t be any opportunities for Russian exploitation — until that contract expires.
In other words, the U.S. had better get some manned launch capability on line before too long. And on that note, see this article: NASA considers man-rating the Atlas V.

Another fuzzy Dawn image?
Another image of Vesta from Dawn has been released. This image was taken on July 9 from a distance of 26,000 miles away. It is definitely an improvement over the previous image, with more small details becoming visible. However, I once again wonder about the softness of the image. Look at the limb of the planet. It is soft against the black sky. This is not what one would expect from perfectly focused camera.
Dawn goes into orbit around Vesta next week. We sure learn then for sure if there is a problem with its camera, or whether I am merely being a bit too nervous.

NASA stalls, Texas lawmakers fume
The law is such an inconvenient thing: In a bipartisan effort, Texas lawmakers roast NASA administrator Charles Bolden for not meeting mandated Congressional deadlines for Congress’s personally designed rocket, the program-formerly-called-Constellation.
The heavy-lift rocket and capsule that Congress insists NASA build is a complete waste of money and nothing more than pork. It will never get built, mainly because Congress has given NASA less money and less time to build it than they did for Constellation under the Bush administration. Unfortunately, the reason they continue to require NASA to build it is to provide pork to their districts.
In a perfect world this funding would be cut now, especially considering the state of the federal debt.

NASA awards a key piece of ISS management to Florida

The story reports that politics were not involved, but I am suspicious. Since all ISS management and operations come out of Houston, why send some of that management to Florida?

Second ARTEMIS space probe about to enter lunar orbit
The second ARTEMIS space probe will enter lunar orbit on Sunday.
“With two spacecraft orbiting in opposite directions, we can acquire a full 3-D view of the structure of the magnetic fields near the moon and on the lunar surface,” said Vassilis Angelopoulos, principal investigator for the THEMIS and ARTEMIS missions and a professor of space physics at UCLA. “ARTEMIS will be doing totally new science, as well as reusing existing spacecraft to save a lot of taxpayer money.”

Dawn nears Vesta
I’ve posted earlier about Dawn’s approach to Vesta. However, in looking at the images from Dawn, it dawned on me recently that they seems more fuzzy for what you’d normally expect from a space probe. I am now wondering if there is something fundamentally wrong with Dawn’s camera, causing its images to be slightly out of focus.
