An evening pause: Normally I don’t post videos with no visuals, but for this I will make an exception. It is probably the first time anyone has ever done the hard work necessary to translate the mumblings of the singer to find out the lyrics of this pop tune. Before now, who knew?
Hat tip Phil Berardelli.
Sorry for the lack of posting today, or tomorrow. I am on a research trip in California and won’t be back home until late on Tuesday. Normally I would post along the way but cannot as I am doing all the driving, and when I am in the National Archives research room in California there is no time.
An evening pause: To start the week, here’s an interesting way to make a living. Hat tip Rocco.
In a long and very detailed post, the chief engineer and mission director of Dawn gives us a very detailed update on the successful state of the spacecraft’s mission.
Not only does he describe what has been gathered at Ceres since the spacecraft arrived a year ago, he gives us this crucial information about the state of this paradigm-shattering ion engine spacecraft, the first to travel to two different objects in the solar system:
Dawn has faced many challenges in its unique voyage in the forbidding depths of space, but it has surmounted all of them. It has even overcome the dire threat posed by the loss of two reaction wheels (the second failure occurring in orbit around Vesta 3.5 years and 1.3 billion miles, or 2.0 billion kilometers, ago). With only two operable reaction wheels (and those no longer trustworthy), the ship’s remaining lifetime is very limited.
A year ago, the team couldn’t count on Dawn even having enough hydrazine to last beyond next month. But the creative methods of conserving that precious resource have proved to be quite efficacious, and the reliable explorer still has enough hydrazine to continue to return bonus data for a while longer. Now it seems highly likely that the spacecraft will keep functioning through the scheduled end of its primary mission on June 30, 2016.
NASA may choose to continue the mission even after that. Such decisions are difficult, as there is literally an entire universe full of interesting subjects to study, but resources are more limited. In any case, even if NASA extended the mission, and even if the two wheels operated without faltering, and even if the intensive campaign of investigating Ceres executed flawlessly, losing not an ounce (or even a gram) of hydrazine to the kinds of glitches that can occur in such a complex undertaking, the hydrazine would be exhausted early in 2017. Clearly an earlier termination remains quite possible.
Dawn has proven the value of ion engines. I would expect to see them used many more times in the future, especially missions heading to low gravity environments.
As predicted a few days ago, Ted Cruz surged against Donald Trump in tonight’s four closed primaries.
Though each won two primaries, the numbers gave Cruz the win over Trump in delegates, 69 to 44 (the numbers now adjusted after all the votes have been tallied). Moreover, as noted at the link, Trump’s voting totals remain flat or have declined, while Cruz’s have been rising steadily. It appears that among Republicans either the love affair with Trump is fading, or there never was one and that his support in the previous open primaries came from cross-over Democrats..
In addition, the numbers for both Kasich and Rubio are going nowhere, which means voting for them in future primaries will essentially give Trump an undeserved win. Thus, expect the movement from them to Cruz to increase.
More here, confirming my analysis above.
A report from New Scientist today claims that the New Horizons science team has possibly seen individual clouds in some images.
Grundy had spotted features in the haze on the edge – or “limb” – of Pluto that seemed to stand out from the distinct layers. But more intriguingly, he had also seen a bright feature crossing different parts of the landscape, suggesting it was hovering above. The email kicked off a discussion as to whether the clouds were real, because it was difficult to see whether they cast shadows on the ground. The team also deliberated over the exact distinction between clouds and hazes. “One way to think of it is that clouds are discrete features, hazes widespread,” wrote Alan Stern, who heads up the New Horizons mission.
There has been no public mention of the clouds, suggesting that the team isn’t sure about the detection.
The competition heats up? Russia’s giant aerospace monopoly Roscosmos has given formal permission for the development of a suborbital space tourism project, proposed by the formally independent company, KosmoKurs.
Russia’s State Space Corporation Roscosmos has admitted the private space company KosmoKurs to working out a project for the development of a reusable system for space tourism flights, KosmoKurs Director General Pavel Pushkin said on Friday. “Our technical design specification was approved by Roscosmos two days ago. The system’s preliminary design will be created with this document,” Pushkin said at the InSpace forum.
According to him, the technical design specification has also been approved by the Central Research Institute of Machine Building (TsNIIMash) and the Keldysh Research Center. In addition, Pushkin said, Roscosmos chief Igor Komarov has already approved the project. “Igor Anatolyevich has taken the project with enthusiasm and gave orders to promote this project”, Pushkin said.
So, if I understand this right, this private company had to get approvals from Roscosmos’s bureaucracy, two other competitive groups within Roscosmos, plus the head of Roscosmos itself, before it would be allowed to proceed with building its independent suborbital operation. I wonder how many bribes KosmosKurs had to pay along the way. I also wonder what kind of quid pro quo deals that had to make in order get those other institutes to give their okay.
With Russia’s aerospace industry function under this kind of set-up, I doubt they are going to get much done in the coming decades.

The competition heats up: Though there is no word yet on their attempt to land the first stage on a barge, SpaceX today has successfully launched a commercial communications satellite.
Update: The barge landing did not succeed.
The betrayal begins: At the debate last night Donald Trump noted that he is already beginning to consider easing his hardline immigration stance.
In Detroit, Fox News’ Megyn Kelly pointed out that Trump’s campaign website has a strong statement against increasing the number of H-1Bs, saying it would “decimate American workers,” and yet in one debate Trump spoke favorably of the program. “So, which is it?” Kelly asked.
“I’m changing,” Trump said. “I’m changing. We need highly skilled people in this country, and if we can’t do it, we’ll get them in. But, and we do need in Silicon Valley, we absolutely have to have. So, we do need highly skilled,” Trump continued, “and one of the biggest problems we have is people go to the best colleges. They’ll go to Harvard, they’ll go to Stanford, they’ll go to Wharton, as soon as they’re finished they’ll get shoved out. They want to stay in this country. They want to stay here desperately, they’re not able to stay here. For that purpose, we absolutely have to be able to keep the brain power in this country.
“So you are abandoning the position on your website?” asked Kelly.
“I’m changing it,” Trump said, “and I’m softening the position because we have to have talented people in this country.”
I’ve said from the beginning that Trump is not a reliable conservative, that his roots are liberal, even if they aren’t radical leftwing, and that once he gets in power he will be no different than either George Bush or even Bill Clinton.
Thus, I am not surprised that he “softening the position”. What surprises me is that he is revealing this now, even before he has gotten the Republican nomination. I wonder if anyone will really notice.
Our fascist government: A medical company and its head was pursued and persecuted for five years by the Department of Justice, based on a false accusation by a former employee, only to lose its case when it finally presented its case to a jury.
It all started when one of our salesmen became upset he didn’t receive a promotion. So he quit and filed a baseless complaint with the U.S. attorney’s office in San Antonio, alleging a multitude of offenses to try to justify a $20 million claim. Simply by hiring a lawyer and making wild accusations, this former employee with an ax to grind became entitled under the law to receive 20 percent of whatever money the government could “recover” from Vascular Solutions.
The government lawyers reviewed his allegations and chose to pursue just one. I offered to meet with them to correct their misinformation, but two days before that scheduled meeting, they called my lawyer and canceled it. And they never would reschedule. So before deciding to bring criminal charges, these prosecutors never heard my side of the story.
Instead, they subpoenaed over 2 million pages of our documents and interviewed over 60 customers and employees. In the process, they received evidence that conflicted with the story told by that money-motivated former employee. But instead of changing their conclusions to fit the evidence, these prosecutors engaged in obscene tactics to try to change the evidence.
In conversation with our lawyers, they called conflicting statements by witnesses “a line of sh*t.” They referred to one employee as “a poor f***er” who needed to return “on bended knee” to “fix” his testimony. They told a female employee to think about what would happen to her firstborn son if she were indicted because she refused to “cooperate.” And by “fix” and “cooperate,” I mean retract their prior testimony and support the government’s case.
Granted, this is written by the man whom the government was trying to prosecute. Still, I believe him, especially because of one key fact he outlines once they went to trial:
In the end, after I endured four weeks sitting in a San Antonio courtroom while still running Vascular Solutions in Minnesota, the jury rejected each and every allegation. And that was without hearing from any of our 20 witnesses, since we made the decision to rest immediately after the government finished its case. So the government’s own witnesses proved our innocence — simply stunning.
The company says it spent $25 million defending itself. It is now calling for an investigation and a firing of these Justice Department lawyers. How many of you expect the Obama administration to follow through with this? I don’t.
Cool image time! The above image, cropped and reduced slightly for presentation here, was taken by one of Curiosity’s navigation cameras on March 2. Though the science team has not captioned it, I think it is looking down from the heights that Curiosity has climbed and across the plains of Gale Crater to its rim in the far distance. The image itself appears to have been taken after the rover spent several days climbing up to what they have dubbed Naukluft Plateau.
Be sure to check out the full resolution image that can be found here.
