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

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 face of the sun is nearly blank.”

10:14 am

Today NOAA posted its monthly update of the solar cycle, and as I do every month, I am posting it here, with annotations.

Before we take a look at that, however, there is other climate news that is apropos. The Daily Mail in the UK put out an entertaining article on Saturday with the headline “And now it’s global COOLING! Record return of Arctic ice cap as it grows by 60% in a year.”

The article is entertaining because, after illustrating the ice-cap’s recovery this year, it then notes the 2007 prediction by global warming climate scientists that the Arctic Ocean would be “ice-free” by 2013. If this isn’t a good example of the dangers of crying wolf, I don’t know what is.

I should emphasize that the ice-cap recovery this year does not prove that global warming has ceased. A look at this graph from satellite data shows that even though the Arctic icecap has recovered, it is still remains small when compared to the past few decades. The increase this year might only be a blip, or it could be indicating a new trend. We won’t really know for another five years, if then.

The article is also entertaining because it outlines the confusion that is right now going on behind the scenes at the IPCC. The next IPCC report is scheduled to come out next month, but no one agrees with its conclusions because it apparently ignores or minimizes the approximately fifteen year pause in warming that has now been documented since the late-1990s.

In its draft report, the IPCC says it is ‘95 per cent confident’ that global warming has been caused by humans – up from 90 per cent in 2007. This claim is already hotly disputed. US climate expert Professor Judith Curry said last night: ‘In fact, the uncertainty is getting bigger. It’s now clear the models are way too sensitive to carbon dioxide. I cannot see any basis for the IPCC increasing its confidence level.’ [emphasis mine]

It appears that scientists and governments are demanding approximately 1500 changes to the IPCC draft, which suggests its release will be delayed significantly.

Meanwhile, the Sun continues its lackluster and weak solar maximum.

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.

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.

Orbital Sciences prepares its Cygnus capsule for its first flight to ISS, set for launch on September 17.

8:59 am

The competition heats up: Orbital Sciences prepares its Cygnus capsule for its first flight to ISS, set for launch on September 17.

Orbital officials said the Cygnus spacecraft was scheduled to be attached to the upper stage of the Antares launcher Wednesday. Final cargo loading into the Cygnus spacecraft’s pressurized module is set for Saturday, followed by its enclosure inside the rocket’s 12.8-foot-diameter payload fairing.

Rollout of the Antares rocket from its horizontal integration facility to the launch pad one mile away is expected Sept. 13.

September will be a busy and important month for private space. We also will have SpaceX’s first commercial launch with its Falcon 9 rocket. If both are successful, the trend away from a big government space programs shall accelerate.

Despite the astronauts’ success on ISS in recreating the spacesuit water leak, NASA engineers still do not know its cause.

3:54 pm

Despite the astronauts’ success on ISS in recreating the spacesuit water leak, NASA engineers still do not know its cause.

What is unstated about this problem is that, because we used to have a big space shuttle with lots of cargo capacity, the American spacesuit was designed to be maintained and repaired on the ground. In the past the next space shuttle flight would have brought a new spacesuit to the station while taking this defective suit back to Earth for analysis and repair. Now that we don’t have a big space shuttle, our complex spacesuits are far more difficult to troubleshoot.

The solution? First, keep it simple. The Russians, limited by the capacity of their Progress and Soyuz capsules, made their Orlan spacesuit very simple and easy to use.

Second, get as many redundant replacements of the shuttle operating as soon as possible.

Astronomers submit a slew of proposals for using the partly crippled Kepler space telescope.

Astronomers submit a slew of proposals for using the partly crippled Kepler space telescope.

Ideas range from a survey of potentially hazardous near-Earth objects to a study of Jupiter-sized exoplanets in large orbits. Kepler scientists will sort through the proposals and decide by 1 November which ones, if any, to recommend to NASA headquarters for further review.

Sadly, none of these ideas excites me very much. The tragedy here is that we have this really good optical telescope above the atmosphere, and we can’t point it accurately enough to use it.

“The [US Justice Department] just stuffed a rag in Barrett Brown’s mouth, as well as his lawyers.”

“The [US Justice Department] just stuffed a rag in Barrett Brown’s mouth, as well as his lawyers.”

The case might be complicated, and Brown might have even broken a reasonable privacy law, justifying his imprisonment. Nonetheless, it disturbs me greatly that the government’s response is to silence the man. Something about this stinks.

Leftwing civility: A college professor threatened a student during in a rant in which he insulted Republicans and even Mitt Romney’s wife.

Video at the link. The threat is veiled but it there nonetheless. The whole rant itself is quite disgusting, especially for a teacher to do it in class, when he has a captive audience.

Taxing both the rich and the sick to pay for Obamacare.

9:43 am

Finding out what’s in it: Taxing both the rich and the sick to pay for Obamacare.

Key quotes:

The change will negatively impact parents who have special needs children and who use FSA funds to help pay for tuition in special needs schools, says Xavier Epps, owner of XNE Financial Advising.

and:

For the more than 10 million individuals and families that claim medical expenses in 2011, there’s more bad news. In order to claim medical expense deductions in 2013, the claims must be at least 10% of AGI, up from 7.5% in the past. There’s an exception for people who are age 65 and older at the end of the year and for married taxpayers with only one spouse age 65 or over. Their threshold will remain at 7.5% until the 2017 tax year.

Y’know, I have yet to find any documented evidence of Obamacare lowering costs or improving health coverage anywhere. So far, this law has done nothing but balloon costs, limit options, and reduce the ability of people to either get health insurance they can afford or healthcare they need.

But that’s all right. The Democrats passed it! It must be good! Let’s vote for them again so they can do this kind of masterwork in many other places. (Right now, the Middle East and Syria comes to mind.)

Update: Obamacare will hike the cost of healthcare in Wisconsin as much as 125%, while forcing almost 100,000 people to lose their health insurance.

Militant gays force an Oregon bakery out of business.

9:31 am

The thugs win: Militant gays force an Oregon bakery out of business.

The background:

On January 17, a mother and daughter arrived at Sweet Cakes By Melissa, an Oregon bakery owned by the Kleins. When the pair explained they wanted a wedding cake for a lesbian wedding, the shop owners politely refused informing the would-be customers that their religious beliefs don’t condone gay weddings and that, because of this, they did not want the women’s business. Before the week was up the bakery was beset by attacks in person, on the phone, and in email. The gay mafia from across the country had sprung into action to threaten the lives of the religious couple. [emphasis mine]

The threats and loss of business have now forced them to shut their bakery. And the reason: Their religious beliefs forbid them from catering to a gay wedding, an act which would be the equivalent of endorsing that event. Note also that they had not been refusing to serve gays, only refusing to cater a gay wedding.
