Gordon Lightfoot – Carefree Highway
An evening pause: Performed live in Reno in 2000. It is amazing to compare this older Lightfoot with Lightfoot performing in 1974. He is as good, but he looks like a different man.

Broken arm
My posts for the next week or so are going to be shorter than I would prefer. This weekend I had a minor fall during a cave trip and broke one bone in my lower left arm. We were about two hours from the entrance, so the trip out was somewhat entertaining, though it did go smoothly without any significant difficulties. taking about three hours to get back to the surface.
Nonetheless, I am a lefty, so writing is now difficult, and with the cast on my arm touch typing is a challenge as well. I can manage posts, but writing long commentaries will likely not happen for the next week or so while the arm heals or I get a smaller cast.
Update on Saturday’s Proton launch failure
Link here. The failure was in the third stage, which was the cause of a previous Proton failure last May.
Note that the Proton also put a commercial satellite in the wrong orbit in October when the upper stage underperformed.
Overall, the Russians are doing a very poor job in eliminating the serious quality control problems that have plagued their aerospace industry in recent years. If anything, the problems appear to be worsening.
Balanced rock on Comet 67P/C-G
Cool image time! Rosetta’s high resolution camera has discovered a group of balancing rocks on the surface of Comet 67P/C-G.
The image on the right, cropped and brightened by me, shows the most dramatic of these rocks. The scientists are as yet uncertain on how these rocks got to where they are.
“How this apparent balancing rock on Comet 67P/C-G was formed is not clear at this point,” says OSIRIS Principal Investigator Holger Sierks from the Max Planck Institute for Solar System Research (MPS) in Germany. One possibility is that transport processes related to cometary activity played a role, causing such boulders to move from their original site and reach a new location.
It is also possible that the rocks were sitting on a base of ice that simply evaporated away over time.
Another Proton launch failure
Eight minutes into Saturday’s Proton launch, intended to place a commercial Mexican communications satellite in orbit, the Russian rocket failed and broke up.
The Russian launch failures just continue to add up. At this rate their ability to hang on to their commercial customers is becoming increasingly difficult.
Lorrie Morgan – Something in Red
An evening pause: I posted a Morgan 1992 performance of this classic back in 2012. In 1992 she was performing the song when it was fresh and a just released hit. Almost a quarter century later it remains one of the best songs ever written, and so I think I should post it again, this time in a more recent live performance from 2007.
The rage builds, even in a posh DC suburb
A stealth write-in campaign defeated a long-time incumbent on the town council for Chevy Chase, Maryland.
Read it. Everything about this story — the reaction to the election by incumbents and their supporters, the reasons the challenger kept his campaign quiet, why he ran in the first place — illustrates the growing fury that ordinary Americans are feeling toward the people presently in power, even at the lowest levels of government. There is contempt for the general population by those in charge, and that general population is becoming increasingly rebellious about it.
Nina Conti – “I think the world is ready to see my dance moves.”
An evening pause: Really clever and funny routines, especially the last third, when she turns an audience member into her ventriloquist dummy.

Stephanopoulos admits he is a Democratic stooge
Why I consider television news a Democratic Party cesspool: George Stephanopoulos admits that he had donated $50,000 to the Clinton Foundation, even as he conducted interviews condemning critics of that foundation, without disclosing his donations.
Meanwhile, ABC News has absolved Stephanopoulos of any wrong-doing, which is not a surprise, since from the perspective of television news Stephanopoulos didn’t do anything wrong. He supported the Clintons and the Democratic Party, both by how he reported the news and conducted his interviews, and now with money itself. This is exactly what a television news anchor is supposed to do in today’s modern television propaganda machine: Help Democrats get elected.
If you get your news information from this news source, you either are incredibly naive, or are a Democratic stooge yourself.
Update: The amount of money Stephanopoulos donated to the Clintons is actually $75K, not $50K as first reported.
House Science Committee approves changes to space law
In a series of party line votes, the House Science Committee has approved a number of changes to the laws that govern the private commercial space industry.
Almost all of the changes were advocated by the industry itself, so in general they move to ease the regulatory and liability burdens that has been hampering the industry since the 2004 revisions to space law. While it is very unlikely commercial space can ever get free of strong federal regulation, these changes indicate that they can eventually get some of the worst regulations eased.
I should note also that, as expected, the Democrats opposed any easing of federal power. To them, all things must be controlled by the government, and to ease any regulations is to commit the most horrific of crimes. Note also that the Democratic lead in this opposition came mostly from Congresswoman Donna Edwards (D-Maryland), who has announced her intention to run for the Barbara Mikulski’s senate seat. This mark-up hearing thus gives us an idea of the future impact of Edwards should she win.
Arianespace admits it is in a head-to-head competition with SpaceX
In testimony at a hearing in the French parliament the head of Arianespace admitted that the company has been in a head-to-head competition with SpaceX for the past two years, with SpaceX grabbing half the business.
He also claimed that they think they will be able to compete with SpaceX, even if it succeeds in recovering and reusing its first stage.
Israel said Arianespace fully expects SpaceX to succeed in its attempt to recover its Falcon 9 first stage.
But that’s just the start of the challenge, he said. It remains unknown what the refurbishment costs will be compared to the cost of churning out a fresh stage from an existing production line. He said it is also unclear whether commercial fleet operators will immediately accept placing $200 million telecommunications satellites on a rocket with a refurbished stage.
Finally, he said, flying a reusable stage means sacrificing first-stage performance so that enough energy is available to power it back to its recovery point. That power is thus unavailable for the mission, which is one reason why Hawthorne, California-based SpaceX thus far has attempted to recover its stages only on low-orbit missions, not for missions to geostationary transfer orbit, where most commercial satellites operate.
All true, but if Arianespace sits on its hands because of these facts it will eventually lose. It needs to rise to the challenge that SpaceX poses, not poo-poo the challenge.
Sarah Brightman pulls out of her flight to ISS later this year
Citing family issues, Sarah Brightman has suddenly canceled her plans to fly to ISS later this year as a space tourist.
All the press announcements of this decision emphasize that she was doing quite well in the training program, but one wonders. There had been rumors of being replaced in recent weeks, and the “family issues” cited in today’s announcement could be a cover for anything.
Either way, this is unfortunate, because her flight would have been quite entertaining and would have done a great deal to promote the space tourism industry.
What caused the failed separation of the Soyuz and Progress?
A good translation of this week’s press release from the investigation into the April 28 Progress failure indicates that the failure occurred because of an abnormal separation of the freighter from the upper stage.
After reviewing all the materials, members of the State Commission came to a preliminary conclusion that a version of the abnormal separation had been objectively confirmed, which includes two subsequent events related to the depressurization (disintegration after the cutoff of the third-stage engine) first of the oxidizer tank and then of the fuel tank, Roskosmos said.
In other words, the separation was so abnormal it put both the freighter and the upper stages in the wrong orbits, with the Progress tumbling and damaged, and with the upper stage almost immediately disintegrating.
They are now studying the data to try to figure out what caused the bad separation so they can inspect other Soyuz upper stages for the same problem and fix them before launch.
Willie Nelson – Blue Eyes Crying In The Rain
An evening pause: Performed live in 1980, around the time that Nelson, who had been working in relative obscurity for years, had suddenly been “noticed”.
Hat tip t-dub for reminding me that Nelson deserved more notice, again.
Engine failure for Japan’s Procyon probe
The failure of the ion engine of an experimental cubesat called Procyon, launched with Hayabusa-2 to test small satellite technologies, has forced engineers to cancel their attempt to have the probe fly past a different asteroid.
They think dust in the engine caused a short circuit.
New Horizons spots all of Pluto’s 5 known moons
New Horizons has now been able to image all of Pluto’s known moons.
Pluto’s five known satellites are Charon, Hydra, Nix, Kerberos and Styx. At 648 miles (1,043 km) in diameter, Charon is nearly half as wide as Pluto itself, but the other four moons are minuscule. Kerberos and Styx, for example, are thought to be just 4 to 13 miles (7 to 21 km) and 6 to 20 miles (10 to 32 km) wide, respectively.
That the spacecraft has been able to spot them all this soon bodes well for what it will see when if flies past Pluto in July.
NASA announces bold plan to still exist by 2045
“It may seem impossible now, but we hope to realize the vision of establishing a human presence in NASA deeper into the century than ever before imagined,” Bolden added.
When questioned about the plan’s viability, Bolden told reporters that while certain doubts remain, the project was nonetheless an absolutely crucial undertaking for NASA. Bolden further emphasized that the Fortuna Program’s goal was technically achievable on paper, and could feasibly be accomplished in a real-world scenario so long as everything “goes perfectly” for the space agency.
“The first critical step toward reaching our goal is to still be here by the year 2020,” said Bolden, adding that the plan allowed absolutely no room for error. “From there, we will move on to the next phase of the mission, which is to implement an intensive 10-year plan to remain operational. If we meet that goal in 2030, then there’s no reason to believe NASA won’t make it to 2045.”
Read it all. As far as I can tell, there really hasn’t been much difference between NASA’s past two decades and what this Onion piece proposes for NASA’s next three decades.
In fact, after you read the Onion piece above, then read this Orbital ATK press release about the successful results from the solid rocket booster test firing in March. As successful and as legitimate as the engineering was for the booster test, why does the press release sound so much like the Onion article?
Clint Mansell – Lux Aeterna (Requiem for a Dream)
An evening pause: I normally don’t post performances recorded by only one camera, as the visuals can get boring. This performance, however, is an exception definitely worth viewing.
Russians confirm flip of Progress and Soyuz launches
It’s official: The launch of the next crew to ISS will be delayed until late July to allow both a Progress freighter to launch first as well as give investigators more time to figure out what went wrong with the Soyuz upper stage during last month’s Progress launch.
In addition, the crew that had been slated to return to Earth this week will remain on board for another month to reduce the amount of time the station is manned with only 3 astronauts.
It appears that investigation is zeroing in on the upper stage of the Soyuz rocket, whose tanks apparently depressurized prematurely, causing the freighter to separate early and end up in an incorrect orbit.
Is the dark material along Europa’s long surface fissures sea salt?
The uncertainty of science: By creating what they call “Europa in a can” here on Earth, scientists have determined that the dark material that appears to have seeped out of Europa’s long linear fractures might be sea salt from the underground ocean, turned brown by the harsh radiation hitting the moon’s surface.
This result is quite intriguing, but the only thing certain about it is its uncertainty. The only way we will know what this brown material really is will be to go there again with much better equipment and study the material itself
