Very brief descriptions, with appropriate links, of current or recent news items.
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.
The Russians have delayed the next Proton launch, scheduled for September 17, for at least a week.
They have not described the problem in any article I can find, but considering their recent failures it doesn’t surprise me if they are being extra careful now.
Using photos from Dawn astronomers have now assembled an online atlas of the asteroid Vesta that the public can explore.
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.
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.
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.
It appears that Deep Impact is lost.
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.
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. [emphasis mine]
The competition heats up: Orbital Sciences has finished loading its Cygnus capsule and has closed the hatch for next Tuesday’s launch.
After 166 days in orbit, three astronauts safely returned to Earth this evening in a Soyuz capsule.
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.
After more than two weeks the labor strike at the ALMA telescope array in Chile has ended.
Modern America: A tea party leader in Oklahoma has been charged with a felony because he sent an email to an state senator demanding he do his job or face the political consequences.
NASA engineers have successfully fixed the glitch on the LADEE spacecraft.
Having completed its investigation into its scrubbed launch two weeks ago, Japan’s space agency JAXA has announced a September 14 launch date for its new Epsilon rocket.
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.
NASA’s lunar probe LADEE was successfully launched tonight from Wallops Island.
Update: A computer glitch occurred shortly after reaching orbit, causing the computer to shut down the spacecraft’s reaction wheels.
Engineers seem unworried, and expect to have the problem solved within a couple of days.
Some good news from the James Webb Space Telescope: The project manager said today that all the problems outlined in a December GAO report have been resolved.
Some of these issues are also described here.
