CRS-7 Investigation Update On June 28,following a nominal liftoff, Falcon 9 experienced an overpressure event in the upper stage liquid oxygen tank approximately seconds into flight, resulting in loss of mission. Prior to the mishap, the first stage of the vehicle, including all nine Merlin 1D engines, operated nominally; the first stage actually continued to power through the overpressure event on the second stage for several seconds following the mishap.
In addition, the Dragon spacecraft not only survived the second stage event, but also continued to communicate until the vehicle dropped below the horizon and out of range. Review of the flight data proved challenging both because of the volume of data —over 3, telemetry channels as well as video and physical debris—and because the key events happened very quickly.
From the first indication of an issue to loss of all telemetry was just 0. Over the last few weeks, engineering teams have spent thousands of hours going through the painstaking process of matching up data across rocket systems down to the millisecond to understand that final 0.
At this time, the investigation remains ongoing, as SpaceX and the investigation team continue analyzing significant amounts of data and conducting additional testing that must be completed in order to fully validate these conclusions.
However, given the currently available data, we believe we have identified a potential cause. Preliminary analysis suggests the overpressure event in the upper stage liquid oxygen tank was initiated by a flawed piece of support hardware a "strut" inside the second stage.
Several hundred struts fly on every Falcon 9 vehicle, with a cumulative flight history of several thousand.
The strut that we believe failed was designed and material certified to handle 10, lbs of force, but failed at 2, lbs, a five-fold difference. In the case of the CRS-7 mission, it appears that one of these supporting pieces inside the second stage failed approximately seconds into flight.
The pressurization system itself was performing nominally, but with the failure of this strut, the helium system integrity was breached.
This caused a high pressure event inside the second stage within less than one second and the stage was no longer able to maintain its structural integrity. Despite the fact that these struts have been used on all previous Falcon 9 flights and are certified to withstand well beyond the expected loads during flight, SpaceX will no longer use these particular struts for flight applications.
In addition, SpaceX will implement additional hardware quality audits throughout the vehicle to further ensure all parts received perform as expected per their certification documentation.
As noted above, these conclusions are preliminary. Our investigation is ongoing until we exonerate all other aspects of the vehicle, but at this time, we expect to return to flight this fall and fly all the customers we intended to fly in by end of year. While the CRS-7 loss is regrettable, this review process invariably will, in the end, yield a safer and more reliable launch vehicle for all of our customers, including NASA, the United States Air Force, and commercial purchasers of launch services.
Critically, the vehicle will be even safer as we begin to carry U. Launching the seventh cargo delivery mission to the International Space Station. The flight will deliver several tons of supplies, such as new science experiments and technology research, as well as the first of two International Docking Adapters.

These landing attempts move us toward our goal of producing a fully and rapidly reusable rocket system, which will dramatically reduce the cost of space transport. A jumbo jet costs about the same as one of our Falcon 9 rockets, but airlines don't junk a plane after a one-way trip from LA to New York.
Yet when it comes to space travel, rockets fly only once—even though the rocket itself represents the majority of launch cost. The Space Shuttle was technically reusable, but its giant fuel tank was discarded after each launch, and its side boosters parachuted into corrosive salt water every flight, beginning a long and involved process of retrieval and reprocessing.
So, what if we could mitigate those factors by landing rockets gently and precisely on land? Refurbishment time and cost would be dramatically reduced. Historically, most rockets have needed to use all of their available fuel in order to get their payload into space.
That extra fuel is needed to reignite the engines a few times to slow the rocket down and ultimately land the first stage after it has sent the spacecraft on its way. In addition to extra fuel, we've added a few critical features to our Falcon 9 first stage for reusability's sake.
All of these systems, while built and programmed by humans, are totally automated once the rocket is launched—and are reacting and adjusting their behavior based on incoming, real-time data.
So, what have we learned from the most recent landing attempts? The first attempt to land on a drone ship in the Atlantic was in January, and while we came close, the first stage prematurely ran out of the hydraulic fluid that is used to steer the small fins that help control the rocket's descent.
The vehicle has now been equipped with much more of that critical fluid for steering purposes. Our second attempt was in April, and we came close to sticking this landing. It shows the stage's descent through the atmosphere, when the vehicle is traveling faster than the speed of sound, all the way to touchdown.
That controlled descent was successful, but about 10 seconds before landing, a valve controlling the rocket's engine power thrust temporarily stopped responding to commands as quickly as it should have. As a result, it throttled down a few seconds later than commanded, and—with the rocket weighing about 67, lbs and traveling nearly mph at this point—a few seconds can be a very long time.Michael Arrington is a serial entrepreneur, lawyer, business executive, writer, publisher, and information provider.
