Astronomers have compiled the first detailed 3D map of the inner regions of the Milky Way.

Astronomers have compiled the first detailed 3D map of the inner regions of the Milky Way. More here.

They find a box/peanut shaped bulge with an elongated bar and a prominent X-structure, which had been hinted at in previous studies. This indicates that the Milky Way was originally a pure disk of stars, which then formed a thin bar, before buckling into the box/peanut shape seen today.

Today’s static fire test and launch rehearsal of SpaceX’s Falcon 9 rocket was scrubbed.

Wednesday’s static fire test and launch rehearsal of SpaceX’s Falcon 9R rocket was scrubbed.

I hear rumors that there was a fuel leak, but this is not confirmed. Regardless, this scrub could cause another delay of Sunday’s planned launch of the upgraded Falcon 9R with its first commercial payload, as the company wants to do this test prior to launch.

The two Colorado Democrats who were key instigators of that state’s new gun control laws were both decisively voted out of office yesterday in recall elections.

Pushback: The two Colorado Democrats who were key instigators of that state’s new gun control laws were both decisively voted out of office yesterday in recall elections.

The election, which came five months after the United States Senate defeated several gun restrictions, handed another loss to gun-control supporters. It also gave moderate lawmakers across the country a warning about the political risks of voting for tougher gun laws.

The recall elections ousted two Democratic state senators, John Morse and Angela Giron, and replaced them with Republicans. Both defeats were painful for Democrats – Mr. Morse’s because he had been Senate president, and Ms. Giron’s because she represented a heavily Democratic, working-class slice of southern Colorado.

The article says almost nothing about Angela Giron’s defeat, which I find intriguing. She was not expected to lose, considering her district was so Democratic, but her margin of defeat was actually larger than Morse’s. See also this article for a very good election analysis which suggests that any effort by Democrats to impose oppressive gun control laws is going to backfire for them very badly.

Another large satellite is about to fall to Earth.

Chicken Little report: Another large satellite is about to fall to Earth.

Current estimates suggest this could occur anytime between the end of this month and the start of November. When it does, the one-tonne GOCE will plunge rapidly through the atmosphere, burning up as it descends. “Some satellites take decades to come back after finishing operations; we will re-enter in no more than three weeks,” says Esa mission manager Dr Rune Floberghagen. Modelling work indicates that perhaps up to 25% of the spacecraft may survive all the way to the surface.

The odds of this debris hitting anything significant is very small. It can happen however.

Despite the significant increase in the Arctic icecap’s size this winter, satellite data of the icecap’s actual volume and thickness suggest that the new ice was quite thin.

The uncertainty of science: Despite the significant increase in the size of the Arctic Ocean’s icecap this winter, satellite data of the icecap’s actual volume and thickness suggest that the new ice was quite thin.

Prof Andy Shepherd, from Leeds University, said: “Now that we have three years of data, we can see that some parts of the ice pack have thinned more rapidly than others. At the end of winter, the ice was thinner than usual. Although this summer’s extent will not get near its all-time satellite-era minimum set last year, the very thin winter floes going into the melt season could mean that the summer volume still gets very close to its record low,” he told BBC News.

It is not surprising that the ice was thin, considering that the icecap was recovering from a record low the year before. The scientific question, however, is whether the cap will thicken in the coming years or continue to thin out. That it has recovered somewhat in size might be a onetime jump as the decline continues, or it might be indicative of a new growing trend.

SpaceX has again delayed the launch of its first Falcon 9 commercial launch.

SpaceX has again delayed the launch of its first Falcon 9 commercial launch.

This delay appears to be only one day, from Saturday to Sunday, September 15. The static fire test of the rocket on the launchpad appears set for today, and I suspect the one day delay was to give them more time to analyze the results of today’s test.

Also, this quote from the article shows the risks involved with this first launch of the upgraded Falcon 9:

The launch would be the first for the next-generation Falcon 9-R, designed not only to be more powerful but to have the potential for re-use β€” that would be the “R” in “9-R” (which Harris incidentally said is pronounced “niner” according to SpaceX CEO Elon Musk).

Space News’ Irene Klotz talked to Musk late last week and found some nervousness going into the launch. β€œWe’re being, as usual, extremely paranoid about the launch and trying to do everything we possibly can to improve the probability of success, but this is a new version of Falcon 9,” Musk told her.

Why we must remember

I wrote these following words three years ago on the anniversary of the World Trade Center attack. I think they are worth repeating again, especially considering the confusing debacle of this administration’s Syria policy these past few weeks, and the continuing violent and oppressive behavior of the Islamic revolutionaries in that country.

My words on September 11, 2010:

The President has asked us to consider today “a national day of service and remembrance”. Though the sentiment seems reasonable, I must respectively disagree.

September 11 should not be turned into a day to celebrate volunteerism or service or American charity. Though these values are profound, important, and an expression of much of what makes our nation great, they are not why we remember September 11.

We remember the evil acts committed on September 11, 2001 in order to remind us that there is evil in the world.

We remember these evil acts so that we will have the strength to fight that evil, with every fiber of our being.

We remember those who died in order to prevent future attacks and further deaths.

We remember so that no one can ever try to make believe these events did not happen.

We remember so that no one can spread the lie that the perpetrators were something other than what they were: Men who had decided to kill in the name of Islam, based on what they believed their religion taught them.

And finally, and most important, we remember the horrible events of September 11, 2001 so that those innocent murdered souls — whose only crime that day was going to work — will not have died in vain.
