A just released National Research Council report on space junk, Limiting Future Collision Risk to Spacecraft: an assessment of NASA’s meteoroid and orbital debris programs, describes in great and worthwhile detail the increasing problem of orbital debris as well as the technical and budgetary problems that exist for removing it. It is especially worth reading for the stories, such as when a Colorado hiker heard a high-pitched sound and then found a still warm thirty-inch diameter sphere in a foot deep crater. The object turned out to be a titanium tank from a Russian upper stage rocket, launched two months earlier.
What I want to focus on here, however, is one issue the report discusses that, as far as I can tell, has generally been missed. Worse, this issue — somewhat ridiculous when you think about a little — will make removing most of the space junk in Earth orbit far more complicated than ever imagined by engineers.
Simply put, under already agreed-to international treaties, no nation can salvage or collect any debris placed in orbit by another nation. To do so will violate international law, and almost certainly cause an international incident. To quote the report:

Why no one should want to live in California: A new proposed law there would require workers’ compensation benefits, rest and meal breaks and paid vacation time for babysitters.
Under AB 889, household “employers” (aka “parents”) who hire a babysitter on a Friday night will be legally obligated to pay at least minimum wage to any sitter over the age of 18 (unless it is a family member), provide a substitute caregiver every two hours to cover rest and meal breaks, in addition to workers’ compensation coverage, overtime pay, and a meticulously calculated timecard/paycheck.
So it was for the children, eh? Wisconsin teachers retire in droves after new law is passed.
Following a tax hike in January 2011, Illinois has lost more jobs than any other state.
This isn’t rocket science, nor is the data hard to find. Whenever government spending and taxes grow, private business inevitably shrinks.
This is a victory for freedom: A new Florida state law will fine local governments and their officials should they try to enforce any local gun restrictions.
All those ordinances have been illegal for years because state law prevents cities and counties from regulating guns. But a new law, set to take effect Oct. 1, takes it a step further. It allows judgments of up to $100,000 against local governments that enforce such laws. And, in an unusual move, the law also says local officials could be fired and fined $5,000, with no representation from the city or county attorney.
Want a piece of space history? Over 800 space artifacts go up for auction beginning September 15. In addition to letters from Neil Armstrong and Alan Shepard, there’s this:
The First Lunar Bible: A flight-flown intact microfilm King James Bible containing all 1,245 pages. The bible was produced by the Apollo Prayer League, a group of NASA engineers, scientists, administrators and astronauts, and headed by NASA chaplain Rev. John Stout, who worked closely with the astronauts and NASA personnel. This lunar bible was originally slated to fly to the moon on Apollo 12, but a mistake on the lunar landing checklist resulted in the bible orbiting the moon in the Command Module. It was, then, placed on board Apollo 13, but due to a near-catastrophic explosion, the crew did not reach the moon, and instead returned along with the bible to Earth. Bibles were then given to Apollo 14 Lunar Module Pilot Edgar Mitchell who stowed them in his PPK bag and landed them safely on the moon February 5, 1971, on board lunar module Antares.
Pete Harding at NasaSpaceflight.com has written a very thorough review of the changes to the flight manifest to ISS expected due to the August 24 failure of the Soyuz-U rocket.
The space shuttle program officially ended on Wednesday. Note however:
Closeout of the shuttle program is an enormous effort expected to take two years. The program occupied 640 facilities and used more than 900,000 pieces of equipment with a value exceeding $12 billion, according to NASA. Much of the work will take place at Kennedy Space Center, where orbiters have been maintained and prepared for launch. NASA requested $89 million for shuttle transition and retirement work in the 2012 fiscal year that begins Oct. 1, but Congress has not yet approved a budget.
An evening pause: To quote from the youtube page: “A live session from the 1991/92 BBC Scotland broadcast, featuring the Cunningham brothers from Silly Wizard, Charlie MacKerron and Donald Shaw from Capercaillie, Ian MAcDonald from Ossian and various members of the Rankin Family, from Canada.”
It’s all good, but stay with it for the Irish dancing near the end.
Orbital Sciences has gotten its launch license from the FAA for the first test launch of the Taurus 2 rocket, scheduled for later this year.
This rocket is Orbital’s version of the Falcon 9. It is a new rocket, never before flown, yet after this test it is scheduled to fly the Cygnus capsule on its first flight only two months later. Talk about cutting things close!
Uh-oh! The Russians are considering reducing their participation in ISS. Their government might also take over entirely the private portion of their space industry.
Using Hubble Space Telescope images taken over a 14 year period, a team of astronomers led by Patrick Hartigan of Rice University have produced six very short time-lapse movies, showing the changes that have occurred to a variety of interstellar jets and bow shocks over time. The one below is my favorite. They are all worth looking at, as they illustrate forcefully how the changeless heavens are not so changeless.

Juno, on its way to Jupiter, took a look back and snapped this picture of the Earth/Moon double planet.
The image was taken by the spacecraft’s camera, JunoCam, on Aug. 26 when the spacecraft was about 6 million miles (9.66 million kilometers) away.

More details on why the rocket carrying the Progress freighter to ISS failed last week.
Ground controllers successfully replaced a failed circuit box on ISS this weekend, using the two-armed Dextre robot.
Up to now, exchanging the boxes was done by spacewalkers, which always carries a certain level of risk. Dextre was designed to reduce the need for astronauts to conduct spacewalks for routine maintenance, therefore freeing up the crew’s time for more important activities, like conducting science.
Fire them! Police confiscate a woman’s legal guns, then refuse to return them despite admitting they are legally owned.
Her cache [of weapons] somehow caught the attention of Lakewood Police, who paid a visit last September. When they found Rice wasn’t home, they asked an obliging employee of the complex to open up the apartment without her consent. Once inside, they raided the gun rack, making off with 13 firearms worth around $15,000. The only problem: They had no apparent reason to. [emphasis mine]
Not only did the police essentially steal her property, they entered her apartment illegally.

More possible consequences if ISS becomes unmanned: the first test of Dragon will be delayed.
An unmanned ISS will also delay the first launch in February of Orbital Sciences Cyngus cargo vehicle, as this vehicle is like Dragon in that it requires astronauts on board ISS to control the robot arm that grabs and berths the spacecraft.
Obama’s National Labor Relations Board has now told a Catholic university it is not religious enough to be exempt from union organizing, even though the Supreme Court has ruled the board has no right to do any such thing.

Good news: The Russians have pinned down a preliminary cause for the Progress launch failure last week.
Solving this quickly appears essential, as the space station was not really designed to fly unmanned.
Past NASA risk assessments show there is a one in 10 chance of losing the station within six months if astronauts and cosmonauts are not onboard to deal with any critical systems failures. The probability soars to a frightening one in two chance — a 50-percent probability — if the station is left without a crew for a year.
Yesterday I posted a link to a story about Al Gore claiming that any expression of skepticism about global warming is to him no different than racism. Here again is what Gore said,
“There came a time when friends or people you work with or people you were in clubs with — you’re much younger than me so you didn’t have to go through this personally — but there came a time when racist comments would come up in the course of the conversation and in years past they were just natural. Then there came a time when people would say, ‘Hey, man why do you talk that way, I mean that is wrong. I don’t go for that so don’t talk that way around me. I just don’t believe that.’ That happened in millions of conversations and slowly the conversation was won. We have to win the conversation on climate.”
More than at any other time, Gore here has very successfully illustrated the differences between how climate skeptics debate the scientific questions of climate change versus how global warming advocates do it.
