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.

Arianespace offers to pick up SpaceX business

The competition heats up: In an effort to gain more business, Arianespace is offering to add an additional launch to its 2017 schedule for any satellite companies whose payload launch is being delayed by both SpaceX’s Falcon 9 launchpad explosion as well as a delay in Russian Proton launches due to its own technical issues.

In his remarks it seemed to me that the CEO of Arianespace was almost gloating.

In a Sept. 7 interview with France Info radio, Israel reiterated his confidence in what he portrayed as Arianespaceโ€™s more plodding, deliberative โ€” and higher-cost โ€” approach to launches when compared to SpaceX.

Arianespace does not want a reusable rocket for the moment, he said, because itโ€™s not certain that reusability can reduce costs and maintain reliability. The Ariane 6 rocket, to operate starting in 2020, will not be reusable. The company also is wary of the Silicon Valley ethos that champions constant iteration, which he said has been a feature of Hawthorne, California-based SpaceX as well. โ€œWe think that the more a launch resembles the preceding launch, the better we are for our customers because we remain in the โ€˜explored domainโ€™ where everything is understood,โ€ Israel said.

In the short run he and Arianespace might benefit by this situation, but in the long run they will face a shrinking market share if they cannot lower the price of their rockets.

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.

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:

โ€œHaving 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,โ€ said Martin Halliwell, Chief Technology Officer at SES. โ€œThis 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.โ€

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.

Dragon splashes down

The competition heats up: SpaceX’s most recently launched Dragon capsule today returned to Earth and was successfully recovered.

The Dragon is the only spacecraft flying today that can return large amounts of cargo to Earth.

Among the cargo brought back from space Friday were a dozen mice from a Japanese science experiment โ€” the first brought home alive in a Dragon. Samples from mice euthanized as part of an experiment by pharmaceutical company Eli Lilly also were on board. Results were returned from an experiment that studied the behavior of heart cells in microgravity, and from research into the composition of microbes in the human digestive system, NASA said. Findings from both could help keep astronauts healthy during deep space exploration missions.

SpaceX to up its purchase of carbon fiber?

The competition heats up: A Japanese supplier of carbon fiber materials has announced that it and SpaceX are negotiating a multi-year deal worth possibly as much as $3 billion.

The multiyear deal with Tesla founder Elon Musk’s 14-year-old venture is estimated to be worth 200 billion yen to 300 billion yen ($1.99 billion to $2.98 billion) in total. The two sides are aiming to finalize the agreement this fall after hammering out prices, time frames and other terms. SpaceX aims to hold down expenses by re-using rockets and spacecraft. Originally, the company made rockets mostly out of aluminum to keep costs low, using carbon fiber only for a few parts, such as connecting joints.

The U.S. company said in a statement, “Toray is one of a number of suppliers we work with to meet our carbon fiber needs for Falcon rocket and Dragon spacecraft production, and we haven’t announced any new agreements at this time. As our business continues to grow, the amount of carbon fiber we use may continue to grow.”[emphasis mine]

The deal is not yet final, but the highlighted language above suggests to me that, based on SpaceX’s engineering tests of its recovered first stages, it has decided it is worthwhile replacing aluminum with carbon fiber for many more of its rocket parts. The fiber might cost more, but if the first stage is going to be reused, the cost can be distributed over several launches. And because carbon fiber is lighter than aluminum, it will allow their rockets to launch a larger payload.
