Do you have video of the Falcon 9 explosion? SpaceX needs it!
In a series of tweets today Elon Musk put out a call for any videos anyone might have of last week’s Falcon 9 launchpad explosion.
“Still working on the Falcon fireball investigation. Turning out to be the most difficult and complex failure we have ever had in 14 years,” Musk wrote. “Important to note that this happened during a routine filling operation. Engines were not on, and there was no apparent heat source. Particularly trying to understand the quieter bang sound a few seconds before the fireball goes off. May come from rocket or something else,” he said.
Musk also answered questions and responded to comments from the public. When Twitter user @ashwin7002 tweeted at Musk that “there are some videos on YouTube claiming something hit the rocket. Any reality there?” Musk replied, “We have not ruled that out.”
Update on the Falcon 9 launchpad explosion investigation
The Wall Street Journal has an interesting article today describing the investigation into last week’s Falcon 9 launchpad explosion, noting especially how — despite participation by the FAA, NASA, and the Air Force — SpaceX will be entirely in charge of the investigation, in accordance with present law.
The article is clearly lobbying for a change, whereby the government would have more power in these investigations. I personally think a change would be a mistake, that the law as it is now is how it should be. It was their rocket that exploded. Their business model depends on their rockets not exploding. Thus, they have the greatest self-interest in fixing the problem. The other outside players might be helpful, but their presence can only in the long run make things more difficult and slow things down, without making anything better.

Update on Falcon 9 explosion
NASA and SpaceX have released detailed statements about Thursday’s Falcon 9 launchpad explosion, summarizing what is known at the moment as well as the state of the investigation.
Not surprisingly, the failure will cause delays in SpaceX’s upcoming plans as well as force the company to shift launches to a different launchpad that will not be ready until November.
Budget constraints and technical challenges delay commercial crew
A NASA inspector general report released today cites both budget constraints imposed by Congress as well as technical challenges that will delay the first commercial manned mission to ISS until 2018.
When the commercial crew program began, NASA hoped to have routine flights by 2015, but that slipped in large part due to congressional underfunding in the early years. OIG noted today that its 2013 report found that adequate funding was the major challenge for the program. Congress has warmed up to the program, however, and now is approving the full President’s request so funding is not the issue it once was. Technical challenges now are the major hurdle according to today’s report.
The companies’ systems must be certified by NASA before beginning routine flights to ISS. Boeing anticipates receiving certification in January 2018 with its first certified flight in spring 2018, and SpaceX is working toward late 2017 for its first certified mission, the OIG report says. But it is skeptical: “Notwithstanding the contractors’ optimism, based on the information we gathered during our audit, we believe it unlikely that either Boeing or SpaceX will achieve certified, crewed flight to the ISS until late 2018.”
The report has been written prior to yesterday’s Falcon 9 launchpad failure, which will certainly impact the schedule negatively.
Essentially, the report claims that the program was delayed initially by about two to three years because of the refusal of Congress to fund it fully. The delays to come will be instead because of the technical challenges. While I tend to agree with this assessment, I also note that government reports like this are often designed to generate more funds for the agencies involved, not find a better way to do things. If we are not diligent and hard-nosed about how we fund this program I worry that with time commercial crew will become corrupted by the government’s sloppy and inefficient way of doing things, and become as bloated as Orion and SLS. This is one of the reasons I never complained when Congress short funded the program previously, as it forced the companies involved to keep their costs down.
Falcon 9 explodes on launchpad
During a standard prelaunch static test firing today a Falcon 9 rocket exploded on the launchpad.
Obviously, this will put a hold on all of SpaceX’s upcoming efforts.
- Falcon Heavy: Since the explosion was almost certainly caused by a failure in the first stage, they will have to hold off that first Falcon Heavy demo launch scheduled for this fall, since it uses three first stages strapped together.
- Reused Falcon 9: Similarly, the first launch of a recovered Falcon 9 first stage, also set for the fall, will likely have to be delayed until they determine what went wrong today.
- Reused Dragon: NASA had indicated that one of the cargo missions to ISS next year would reuse a previously flown Dragon. Though this explosion has nothing to do specifically with Dragon, the capsule is launched with a Falcon 9, and thus cannot fly until this investigation is over.
- Falcon 9: SpaceX had been attempting this year to up its launch rate to more than one per month. That will now not happen.
- Red Dragon: SpaceX has said it plans to fly a test Dragon to Mars in 2018, the next launch window. While this explosion will delay the company’s plans over the next year, I expect SpaceX will not cancel that 2018 launch. They have enough time to investigate this failure and fix the cause without missing that window.
- Elon Musk’s Mars speech: Finally, Musk is scheduled to make a major speech on September 26 at the International Aeronautical Congress (IAC) in Guadalajara, Mexico, outlining his company’s future plans to fly to Mars. He almost certainly will have to rewrite that speech.
This launchpad explosion is bad news for SpaceX but it is also very puzzling. I cannot remember the last time a rocket exploded on the launchpad during a static fire test. Failures have in recent years always occurred during the actual launch, when the rocket is flying and is thus exposed to large dynamic forces which can cause the engineering to go screwy. For a rocket to explode at the moment it ignites its engines suggests a very fundamental design fault, which seems unlikely considering the number of launches and static fires SpaceX has completed with the Falcon 9, including numerous prelaunch tests of the rocket’s first stage, both on the launchpad and at the company’s test facility in Texas prior to shipment to the launchpad.
Update: SpaceX has now said that the problem occurred near the rocket’s upper stage during fueling, prior to the actual ignition of the engines.
This news is both good and bad. The good news: It means that the failure had nothing to do with the much tested Merlin engines, which would have suggested a fundamental design flaw previously unseen. That is now clearly not the case. The bad news: The update suggests that the problem might be related to SpaceX’s high density, high pressure fueling, which by lowering the temperature of the tanks allows them to load more fuel and oxidizer. This novel approach, only introduced last year in order to give the rocket greater fuel capacity, might have a design problem that they had not anticipated.
Three professors ban skepticism of human-caused climate change
Academic fascists: Three professors teaching an online course at the University of Colorado-Colorado Springs have told their students that they are forbidden to raise any skeptical data or sources or even questions when the issue of man-made global warming is discussed.
Signed by the course’s professors Rebecca Laroche, Wendy Haggren and Eileen Skahill, it was sent after several students expressed concern for their success in the course after watching the first online lecture about the impacts of climate change. “Opening up a debate that 98% of climate scientists unequivocally agree to be a non-debate would detract from the central concerns of environment and health addressed in this course,” the professors’ email continued. “… If you believe this premise to be an issue for you, we respectfully ask that you do not take this course, as there are options within the Humanities program for face to face this semester and online next.”
The professors also note this ban on debate extends to discussion among students in the online forums. Moreover, students who choose to use outside sources for research during their time in the course may select only those that have been peer-reviewed by the Intergovernmental Panel on Climate Change, the email states.
Putting aside the fact that the study claiming that 97% of scientists agree with man-made global warming has been debunked, this refusal to allow open debate by these fake teachers makes them the poster child for fascism in academia.

First relaunch of Falcon 9 1st stage announced
The competition heats up: SpaceX and the Luxembourg satellite company SES today announced that the of SES 10 this fall will use one of the Falcon 9 first stages that has flown previously and been recovered. From the SES press release:
“Having been the first commercial satellite operator to launch with SpaceX back in 2013, we are excited to once again be the first customer to launch on SpaceX’s first ever mission using a flight-proven rocket. We believe reusable rockets will open up a new era of spaceflight, and make access to space more efficient in terms of cost and manifest management,” said Martin Halliwell, Chief Technology Officer at SES. “This new agreement reached with SpaceX once again illustrates the faith we have in their technical and operational expertise. The due diligence the SpaceX team has demonstrated throughout the design and testing of the SES-10 mission launch vehicle gives us full confidence that SpaceX is capable of launching our first SES satellite dedicated to Latin America into space.”
I also like how they call the used first stage “flight-proven.” This story notes that the insurance cost for the launch weren’t raised either.
The exact date has not yet been set, but it will be in the fourth quarter of 2016.
A university declares its stand for freedom
Good news: The University of Chicago has issued a letter that it is distributing to all incoming students that bluntly tells them it does not care if they are offended by some speech and will instead support the speaker’s free speech.
“Our commitment to academic freedom means that we do not support so-called ‘trigger warnings,’ we do not cancel invited speakers because their topics might prove controversial, and we do not condone the creation of intellectual ‘safe spaces’ where individuals can retreat from ideas and perspectives at odds with their own,” reads the letter from Dean of Students Jay Ellison.
You can read the full letter at the link. Whether this will translate into freedom of speech for both liberal and conservative speakers remains to be seen. This college has had several incidents recently where protesters prevented speakers from speaking. The university’s response was to refuse to discipline the protesters for their disruptions, thus allowing the heckler’s veto to win.
The bigots in academia
Two stories today that only confirm what many other previous stories have shown: Modern academia is very bigoted, but instead of favoring white supremacy their focus is promoting black and minority rule.
The second story outlines efforts to create segregated housing and classrooms for the benefit of minorities at a number of different colleges.
It is important to remember that each one of these proposals is being put forth by leftwing academics, all of which I guarantee are partisan Democrats. All they can see is race, which is why they call anyone that disagrees with them a racist. Or to quote the Bible, “And why beholdest thou the mote that is in thy brother’s eye, but considerest not the beam that is in thine own eye?”
SpaceX tests parachutes for manned Dragon
The competition heats up: SpaceX last Friday successfully tested the parachute system for its manned Dragon capsule.
A video of the test can be seen here. They did not use an actual Dragon for the test.
