This igloo-like design is one of the concepts being considered at NASA for the first habitats on Mars.
Normally I don’t waste time promoting these NASA concept studies, since the odds of them getting built is less than zero. However, this idea is intriguing, and probably contains within it many concepts that will be used by the first Martian habitats.
SpaceX today released its final investigation results on the September 1 Falcon 9 launchpad explosion, and announced that they have now scheduled their next launch for January 8 out of Vandenberg Air Force Base.
As expected, the cause is the accumulation of solid oxygen in the wrappings of the helium bottle tank (COPV) inside the oxygen tank of the first stage. The following is their announced solution:
The corrective actions address all credible causes and focus on changes which avoid the conditions that led to these credible causes. In the short term, this entails changing the COPV configuration to allow warmer temperature helium to be loaded, as well as returning helium loading operations to a prior flight proven configuration based on operations used in over 700 successful COPV loads. In the long term, SpaceX will implement design changes to the COPVs to prevent buckles altogether, which will allow for faster loading operations.
Their vagueness in describing the “prior flight proven configuration” is likely to protect proprietary information, but the overall solution suggests that their fuel loading operations will take longer.
The January 8 launch date was simultaneously announced on twitter.
In my daily scanning of the news, looking for stories that are both educational as well as entertaining, I came across this particular post: “WATCH – This Viral Video Perfectly Illustrates Why Americans Don’t Trust the Lamestream Media”.
The title is typical click-bait, hinting at something truly revealing that nine times out of ten turns out to be immensely disappointing. This time, however, I found that the post revealed a lie about political polls, almost as an aside, that is simply never noted.
The video itself is entertaining. It shows one particularly bad performance by a MSNBC political reporter, where in only about five minutes he used NBC polls to make a string of predictions about the presidential election, every single one of which turned out to be spectacularly wrong. I’ve embedded the video below the fold for your enjoyment.
What the post however noted that I found revealing was something else:
After all, these were NBC polls that Kornacki cited time and time again. Polls that showed Hillary Clinton leading Donald Trump in places like North Carolina, Georgia, and Ohio. The polls were terribly off-base. In some cases, the NBC numbers showed Clinton with a double-digit lead in states that she went on to lose. In other words, the polls were not by any means scientific, fair, or truthful.
Does the phrase “margin of error” ring a bell? Typically, it is between three and four percent, in order to be deemed usable, anyway. But NBC’s margin of error in Pennsylvania was 11 percent. [emphasis mine]
In the past decade or so political polls have routinely included what they call their “margin of error,” which generally for most polls ranges, as noted above, about three to four percent. This number is, and has always been a lie, however, as shown by the highlighted text. The real margin of error is the difference between what the poll predicted and what the actual results were. And for all of these NBC polls, the margin of error was not 3 to 4 percent, but anywhere from 11 to 30 percent!
In other words, these polls were worthless. Worse, they suggest some intentional manipulation, as they all made their error in only one direction (against Trump and for Clinton), much like the tampered global temperature data that we see coming from NASA and NOAA. It could be that there is confirmation bias going on here, producing results these liberal news outlets wish, but I do not think so. NBC, and its sister station MSNBC, have repeatedly in the past five years committed some egregious journalist frauds, all of which designed to make conservatives and Republicans look bad and to promote the interests of the Democratic Party. The network has made no moves to correct the problems. Nor has it fired anyone.
I think it very reasonable to suspect intentional fraud here, specifically aimed at helping the Democrats.
More important, this story illustrates why we should all laugh uproariously the next time we see a mainstream media journalist note pompously that the poll he or she is citing has a margin of error of 3%. He or she either doesn’t know what they are talking about, or they know very well and think you are too stupid to notice.

Doug Messier today has compiled a list showing the launch totals worldwide for 2016, showing that though the U.S. and China tied for first with the most launches, 22, the U.S. won the race with fewer launch failures. Russia fell to third, almost entirely because its Proton rocket has been grounded since June.
What I find interesting is that, very slowly, the competing American companies are beginning to compile launch numbers that match those of whole nations. ULA completed 12 launches, which beat everyone but the U.S., China, and Russia. SpaceX, despite no launches after its September 1 launchpad explosion, still beat India and Japan, long considered established space powers, and finished only one launch total behind Europe.
Eventually, I believe SpaceX is going to get its technical problems ironed out. When that happens, the competition between them and ULA could have both companies producing numbers that beat out the national programs of Russia and China. In fact, I expect this to happen within three years, but more likely sooner.
Failure theater: Two resolutions, one in the House and the other in the Senate, are going to be offered by Republicans to condemn the UN resolution that declared Israel’s presence in parts of Jerusalem and Israel to be illegal.
Sen. Jerry Moran (R-KS) was quoted by The Hill as having said on Friday he will introduce a measure on Tuesday expressing support for Israel and throwing the “sense of the Senate” behind disapproving the United Nations resolution. “Over the last eight years, the Obama administration has made a series of blatantly misguided choices when it comes to working with our strongest ally in the Middle East,” Moran said in a statement. He added the Trump administration will “have to work overtime to repair the damage President Obama has done.”
Separately, Rep. Dennis Ross (R-FL) said Friday he is offering a resolution condemning President Barack Obama and the United Nations “for their dangerous anti-Israel actions”, according to The Hill.
Neither resolution will have any teeth. Essentially, they will declare that the UN was mean for what it did, but the U.S. Congress ain’t going to do anything about it.
Obviously, Congressional action might not end with these resolutions, but do not be surprised if this is all these cowards do.
