What the Middle East conflict looks like from inside Israel

12:34 am

As I am in Israel this week visiting family, I have had an opportunity to get a feel for the political and cultural atmosphere of the Middle East. Granted, this “feel” is very superficial and subjective, but it is nonetheless instructive, as I am viewing the situation not as a resident but as an outsider who always favors freedom and justice in any political conflict.

Anyway, my sense of the situation here comes from two immediate sources, one cultural and the second personal. First the cultural.

Heading to Israel

6:50 am

This morning I will be boarding a plane to begin the long tedious airplane flight from Tucson to Jerusalem, Israel, arriving there Thursday afternoon. I might post along the way, but there are no guarantees.

For the next week I will once again be staying with my brother and sister-in-law in their apartment in the west bank settlement of Alon Shvut. It was here at the bus stop just outside the settlement, where Palestinians and Israelis routinely gather to either catch the bus or hitchhike a ride to Jerusalem, that three Israeli teenagers were kidnapped by Hamas operatives, sparking the recent conflict in the Gaza Strip. Then, just a few weeks ago an Arab terrorist when on a killing spree at this bus stop, killing one young woman before the guard at the settlement gate ran down the hill to shoot him.

I might post my impressions of the situation while I am there, or it might have to wait until I return. It depends on my schedule and my desire to work while visiting family. Yesterday’s attack in a Jewish synagogue, once again by Hamas operatives, killing five people whose only crime was that they were praying peacefully, might also touch my family directly, as I think that one of the rabbis killed was a friend of my brother, his wife, and their children. I will find out more when I get there.

Meanwhile, there were Arab celebrations in various locations in Gaza, the West Bank, and even in Jerusalem, congratulating these killers for their barbarous acts.

Close-up image of Philae’s landing site

Agilkia landing site for Philae

Inset of landing site

In the preparation to Wednesday’s landing of Philae on Comet 67P/C-G, Rosetta’s science team has released a great image of the landing site, shown above. To the right is a higher resolution inset of the site itself, with the smallest object visible about 8.5 feet across.

Looking at this inset, there are some obvious worries that we all should be aware of prior to the landing attempt. Though the Agilkia landing site is generally more smooth than most of the comet’s surface, it still has significant hazards. The lower part is strewn with boulders and rocks, many of which are quite large. Any one of these could do serious harm to Philae should it land on them.

Even more interesting is the upper part of the landing site. Though very smooth, the image suggests to me that this is a very thick pile of softly packed material. Philae might land there and quickly sink below the surface, where its cameras will be able to see nothing.

Nonetheless, the science team has also released this outline of Philae’s science timeline after landing. The lander will also be taking images of both Rosetta and the comet during its descent, so even if the landing is a failure we will still get some worthwhile data.

Focusing on strategy instead of substance

6:14 pm

This article, about the back room maneuvers by both political parties leading up to last week’s election, has been making the rounds on all the political websites. Called a “must-read, vivid piece”, it reveals all the strategies, mistakes, and childish in-fighting that took place during the campaign, the kind of stuff that makes many people consider politicians such a lower form of life.

I am normally not interested in these smoke-filled backroom stories as I care a lot more about what politicians do when they are in office. This is why I didn’t read the article until today, two days after it was published and after I had seen it quoted in maybe a dozen other political articles about the election.

Having read it I have to agree it is worthwhile reading, but my main take-away is that its focus on the campaign strategies and maneuvers by politicians of both parties epitomizes all that is wrong with modern political journalism as well as the interests too many of its readers. Only once did the article hint at the actual issues crucial to the election, when it summed up the Republican strategy near the beginning of the article:

From the outset of the campaign, Republicans had a simple plan: Don’t make mistakes, and make it all about Obama, Obama, Obama. Every new White House crisis would bring a new Republican ad. And every Democratic incumbent would be attacked relentlessly for voting with the president 97 or 98 or 99 percent of the time.

That’s it. That’s the only hint at real substance in this whole very long and detailed article.

For you see, the election was about Obama and his fumbling incompetence. It was about the policies he and his Democratic supporters in Congress had foisted on the nation. And it was about how those policies have been a disaster for ordinary people all across the nation.

All the games that these politicians play against each other during campaigns really isn’t that important. It might tell you something about their character, but what really matters is what these guys do, when they are in office. Keep that in mind when the next election rolls around, because I guarantee that the politicians and the journalists who write about them are not going to be interested in talking about that. It would be far too embarrassing.

Taking a broad look at Tuesday’s Republican sweep

6:33 pm

I don’t have much to add to the numerous reports about yesterday’s election by political pundits far more qualified than I. The Republicans won a big landslide victory yesterday, not only gaining control of the Senate, but winning more seats than expected. They also won more seats in the House than expected, widening their majority there to numbers not seen since the 1920s. In addition, they made it a grand slam by winning a plethora of governorships — many in Democratic stronghold states such as Massachusetts, Illinois, and Maryland — as well as taking control of more state legislatures than ever before.

What matters to me, however, is not the election but what this new Republican majority does with its majority. In the past, 1994 and 2000, they more or less squandered the opportunity to rein in government. In 1994, they allowed the government to grow but at a rate below the rate of inflation so that in a few years this resulted in a balanced budget and surpluses. But the government still grew in power and size. In 2000 they did not even do this, allowing government spending and yearly deficits to balloon, even though they had a Republican president who would have supported them if they had wanted to cut the size of government.

Thus, while I am hopeful, I also remain very skeptical about what will happen in the next few years. In order to prove to me and the conservative base that elected them that these Republicans mean what they say when they say they want to shrink the size of government, they are going to have to prove it with real action. They are going to have show us that they really do want to repeal Obamacare. They are going to have to show us that they really do want to gain some control over the border. And they are going to have to show us that they really do want to cut the budget and get it balanced.

I understand that the Democrats in the Senate and Obama can still block many of these initiatives, but too often Republicans have used this fact as an excuse to not try at all. This must stop! They must apply strong pressure on these left wing ideologues, make them reveal their politics for all to see by forcing them to veto or block these initiatives. Only by demonstrating a resolve to rein in government will anyone believe the Republicans when they claim that’s what they want to do. And by doing so they will also simultaneously expose the Democrats as the left wing ideologues that they are.

Making these points can only be for the good, politically.

Two more points, often unstated but fundamental to what elections in the United States represent.

Signs of a sunspot ramp down

1:39 pm

The monthly update by NOAA of the solar cycle is out, showing the sunspot activity for the Sun in October, As I do every month, I am posting it here, with annotations to give it context.

Despite the appearance last month of the largest sunspot in almost a quarter century, the number of sunspots in October dropped significantly, bringing overall activity back to levels seen in 2012, prior to the second peak in the solar maximum. If things go as expected (not something I would bet much money on), the overall ramp down of sunspot activity should now continue over the next few years. There will obviously be jumps periodically, but the general output of sunspots should steadily decline.

I also want to reiterate what I noted last month, that the 2009 prediction of the solar scientist community is looking better and better with time. Other than over-estimating the total activity somewhat while missing the dip between the two peaks, their overall curve, indicated by the red line, is reasonably close to what has actually happened.

October 2014 Solar Cycle graph

The graph above has been modified to show the predictions of the solar science community. The green curves show the community’s two original predictions from April 2007, with half the scientists predicting a very strong maximum and half predicting a weak one. The red curve is their revised May 2009 prediction.

Antares launch failure

3:35 pm

Immediately after lifting off from the launchpad this evening, Orbital Sciences’ Antares rocket exploded, falling back onto the launchpad.

We will have to wait for more details, but regardless this is bad news for Orbital Sciences. The bidding for the second round of cargo contracts to ISS is about to begin, and they will have competition from Sierra Nevada’s Dream Chaser. This accident will hurt them.

I’ve embedded footage of the launch failure below. The damage to the launchpad itself could be the worst aspect of this, as it will cost Orbital Sciences a great deal of money and time to get the pad rebuilt.

NASA treats Congress like a doormat, again

9:34 am

Stupid: More than a month after publicly awarding commercial crew contracts to SpaceX and Boeing, NASA has yet to brief Congress on the reasons for its decision.

“To date, the Committee has not been briefed on the source selection, nor has it received the source selection statement, despite the fact that the offerors have been briefed, details were released to the press, the [Government Accountability Office] is now involved; and NASA has decided to proceed with the contracts,” Reps. Lamar Smith (R-Texas) and Steven Palazzo (R-Miss.) wrote in a letter to NASA Administrator Charles Bolden dated Oct. 21. Smith and Palazzo chair the House Science Committee and House Science space subcommittee, respectively.

“We hope that NASA will not expect taxpayers to blindly fund billion-dollar programs absent any information related to the procurement or contract,” wrote Smith and Palazzo, who are ardent supporters of the Space Launch System, major contractual details of which were only finalized this year and have not yet been made public.

These elected officials are not NASA’s allies when it comes to commercial space, so giving them too much information is probably dangerous. At the same time, the choice of Boeing was certainly done to ease their concerns, and keeping them out of the loop is only going to turn them against the commercial space contracts. It serves no purpose. NASA should instead be trying to show them why picking SpaceX and Boeing made sense, and how these two multi-billion dollar contracts will bring many jobs to their districts.

If NASA doesn’t do this basic political massaging, these guys are simply going to try to cut commercial space out when it comes time to negotiate the budget, as they have already tried to do several times in the past.

But then, when it comes to politics this behavior by the Obama administration is par for the course. They might have the right idea, farming out space exploration to the private sector, but their political implementation has often left much to be desired.

Orion ready for launchpad!

9:15 am

Be still my heart! NASA has completed the assembly of the Orion capsule stack, prior to installing it on its rocket on the launchpad.

I remain decidedly unexcited by this upcoming test flight, which will send Orion up to 3,600 miles and then bring it back to Earth at about 20,000 miles per hour to test the spacecraft’s heat shield.

For example, the exaggerations and overstatements in this one short article tell you a great deal about how oversold the SLS/Orion program is.

The X-37B goes to Mars

12:24 pm

After 675 days in space, the Air Force’s reusable X-37B mini-shuttle successfully returned to Earth today, completing its second flight in space.

There has been a lot of speculation about the secret payloads that the two X-37B’s have carried into space. The Air Force has been very tight-lipped about this, though they have said this:

“The primary objectives of the X-37B are twofold: reusable spacecraft technologies for America’s future in space, and operating experiments which can be returned to, and examined, on Earth,” Air Force officials wrote in on online X-37B fact sheet. “Technologies being tested in the program include advanced guidance, navigation and control; thermal protection systems; avionics; high-temperature structures and seals; conformal reusable insulation, lightweight electromechanical flight systems; and autonomous orbital flight, re-entry and landing,” they added.

The obvious advantage of the X-37B is that it allows the Air Force to test these new technologies in space, then bring them back to Earth for detailed analysis.

However, I think the most important engineering knowledge gained from this flight will not be from the payload, but from the X-37B itself.

A reviving solar maximum

12:32 pm

Last week NOAA posted its monthly update of the solar cycle, showing the sunspot activity for the Sun in September. As I do every month, I am posting it here, below the fold, with annotations to give it context.

As much as I am always willing to point out the errors and foibles of scientists when they get something wrong or overstate their conclusions, I also believe it right to give credit when credit is due. I have been saying for several years now that the prediction of the solar scientist community, indicated by the red curve in the graph below the fold, had seriously overstated the Sun’s sunspot production during this solar maximum.

Well, it now appears that, as the solar cycle continues to run its course, that their May 2009 prediction is becoming increasingly correct.
