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.

12:00 am

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.

10:07 am

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.

9:54 am

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.

9:41 am

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 — 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. “We’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.

The first commercial launch of SpaceX’s Falcon 9 has been pushed back to September 14.

9:48 am

The first commercial launch of SpaceX’s Falcon 9 has been pushed back to September 14.

I must apologize to my readers. I completely missed this news item last week. However, in my defense SpaceX has been unusually tight-lipped this time with information.

The launch itself also seems dependent on a hot fire engine test that SpaceX wishes to do first, which means that the September 14 date might still be pushed back again.

The first and second launch of the Space Launch System are likely to be delayed due to budget issues.

7:56 am

The first and second launch of the Space Launch System are likely to be delayed due to budget issues.

“It’s very clear that we could have slips of a year or two,” said [deputy administrator Lori] Garver, referring to both the 2017 launch — which won’t have a crew — and the first planned flight of NASA astronauts aboard the SLS rocket in 2021.

Garver claims that it is insufficient funds for SLS that will cause the delays, despite getting $3 billion per year, or ten times the money the private commercial program is getting.

I’m on a hike today, but so any additional comments about this insanity will have to wait.

The Russians are including a bathroom in their next generation manned vehicle, something they note Orion will not have.

2:47 pm

The competition heats up: The Russians are including a bathroom in their next generation manned vehicle, something they note Orion will not have.

A new Russian spaceship for trips to the moon or the International Space Station will have at least one crucial advantage over its American rival – a toilet, one of the craft’s developers said Friday. “I don’t think I need to elaborate on how a waste-collection system is much more comfortable than the diapers that astronauts aboard the [US spacecraft] Orion will have to use,” said Vladimir Pirozhkov of the Moscow Institute of Steel and Alloys, which is involved in the development of the Russian ship. “Besides, the Russian segment of the International Space Station [ISS] has a limited number of toilets, which means a spacecraft with an extra ‘space toilet’ will come in handy,” he added.

As much as I am skeptical of Orion and SLS, I am equally skeptical of the Russian claims of a next generation manned spacecraft. They have been unveiling these proposals now for more than a decade, with nothing ever getting built. With Orion we at least have an existing capsule, even if its bulkhead needed to fixed.

Though I will agree with them on one point: Putting a toilet on a vehicle intended to go beyond Earth orbit, which Orion is supposed to be designed to do, makes common sense. That NASA didn’t include this essential item in Orion reveals to us the unseriousness of the spacecraft.

While the launch industry eagerly awaits SpaceX’s first commercial Falcon 9 launch on September 10, Arianespace has been signing up customers.

10:16 am

The competition heats up: While the launch industry eagerly awaits SpaceX’s first commercial Falcon 9 launch on September 10, Arianespace has been signing up customers.

Arianespace Chief Executive Stephane Israel said Aug. 29 after the last Ariane 5 launch that the company has booked around 300 million euros ($400 million) in new orders in recent weeks, bringing this year’s total contract volume to 1 billion euros. Industry officials said the contracts are for government missions in Brazil and Japan, and commercial operators in Brazil, the United States, Mexico and Spain.

The Ariane 5 is incredibly reliable, having successfully completed more than fifty launches in a row. It is also much more expensive that Falcon 9, which is expected to cost a customer about half as much to get a payload into orbit.

Until SpaceX proves Falcon 9, Arianespace will be in a strong position to get customers. Once Falcon 9 starts flying regularly however, Arianespace will begin to lose business to this cheaper alternative. Thus, the new contracts will help tide the company over while they scramble to figure out how to reduce costs in order to compete.

In related news, SpaceX readies the new upgraded Falcon 9 for launch.

A engineering problem during construction of one of the shuttle-derived solid rocket boosters for SLS is causing delays.

A engineering problem during construction of one of the shuttle-derived solid rocket boosters for SLS is causing delays.

[The] original test target of mid-2013 slipped when an issue with the aft segment [of the booster] was found. Inspection of the segment showed it was contained an area where propellant had debonded from the inside of the segment wall. Following analysis – which notably found no voids in the propellant itself – NASA decided to ask ATK to scrap the segment and cast a replacement.

Preparations … continued, with the shipping and integration of forward and center segments at the test site, while ATK went to work to replace the aft segment, following approval – post investigation – from NASA’s Marshall Space Flight Center. After ATK successfully cast the replacement segment in July, technicians carried out routine ultrasound and x-ray tests. Unfortunately, the tests showed this segment had also had similar voids. [emphasis mine.]

The Space Launch System (SLS), was mandated by Congress to use as much shuttle-derived components as possible in order to supposedly save money as well as employ as many of the companies that built those components as possible. In reality, however, every one of those components has required significant redesign to make them work in SLS. In the case of the solid rocket boosters, the four segment shuttle boosters were not powerful enough. They had to be expanded to five segments.

Moreover, it appears from this article it was other technically unnecessary changes to the boosters that are now causing this problem.

Obamacare is forcing a number of artist organizations to cancel health insurance for its members.

11:29 pm

Finding out what’s in it: Obamacare is forcing a number of artist organizations to cancel health insurance for their members.

The College Art Association website posted a notice this month: “The New York Life Insurance Company recently informed CAA that it will no longer offer catastrophic healthcare coverage previously available to CAA members.” Why? Because it “is no longer an option” for “associations whose members reside in different states” to provide such coverage. These members will have to seek help from their home states’ newly formed Obamacare exchanges. Plans offered to Modern Language Association (MLA) members will suffer a similar fate.

Other insurance providers are reporting cancellations. The Entertainment Industry Group Insurance Trust (TEIGIT) website posts the following notice: “All individual and/or Sole Proprietor Health Insurance will terminate January 1, 2014. This includes plans acquired as Members of our Affiliated Associations & their groups.” Those affiliated associations include the American Federation of Television and Radio Artists, the Dramatists Guild, the Graphic Arts Guild, NY Women in Film and Television, and many others.

From my experience in the movie industry it is almost certain that the vast majority of these artists, writers, musicians, and actors are Democrats who blindly supported Obama and Obamacare. I am also certain that, even after this disaster, they will still blindly support the Democratic Party.

NASA has put Orbital Sciences on notice that, assuming its demo cargo mission to ISS in two weeks is a success, the company might have to do it again as soon as December.

The competition heats up: NASA has put Orbital Sciences on notice that, assuming its demo cargo mission to ISS in two weeks is a success, the company might have to do it again as soon as December.

SpaceX is supposed to fly its next cargo mission first, but NASA thinks that flight will be delayed because of development issues with the upgraded Falcon 9 rocket.

A Russian astronaut, scheduled to fly to ISS in 2015, has unexpectedly resigned.

11:02 pm

An experienced Russian astronaut, scheduled to fly to ISS in 2015, has unexpectedly resigned.

No explanation other than that he found “a more interesting job” was given for his resignation, but this paragraph might give us a hint:

The Gagarin Cosmonaut Training Center has been rocked by reorganization problems since 2009, when it was transferred from the Defense Ministry to the civilian Federal Space Agency. An unnamed Russian cosmonaut told the Moskovsky Komsomolets newspaper last year that the prolonged reorganization had affected cosmonauts’ income and career prospects, breeding discontent in the ranks.
