SpaceX Statement on Rocket Explosion

SpaceX released this statement yesterday regarding Thursday's rocket explosion in Florida:
SpaceX has begun the careful and deliberate process of understanding the causes and fixes for yesterday's incident.  We will continue to provide regular updates on our progress and findings, to the fullest extent we can share publicly.
We deeply regret the loss of AMOS-6, and safely and reliably returning to flight to meet the demands of our customers is our chief priority.  SpaceX's business is robust, with approximately 70 missions on our manifest worth over $10 billion.  In the aftermath of yesterday's events, we are grateful for the continued support and unwavering confidence that our commercial customers as well as NASA and the United States Air Force have placed in us.
Overview of the incident:
 - Yesterday, at SpaceX's Launch Complex 40 at Cape Canaveral Air Force Station, an anomaly took place about eight minutes in advance of a scheduled test firing of a Falcon 9 rocket. 
- The anomaly on the pad resulted in the loss of the vehicle.
- This was part of a standard pre-launch static fire to demonstrate the health of the vehicle prior to an eventual launch. 
- At the time of the loss, the launch vehicle was vertical and in the process of being fueled for the test.  At this time, the data indicates the anomaly originated around the upper stage liquid oxygen tank.  Per standard operating procedure, all personnel were clear of the pad.  There were no injuries.
To identify the root cause of the anomaly, SpaceX began its investigation immediately after the loss, consistent with accident investigation plans prepared for such a contingency.  These plans include the preservation of all possible evidence and the assembly of an Accident Investigation Team, with oversight by the Federal Aviation Administration and participation by NASA, the United States Air Force and other industry experts.  We are currently in the early process of reviewing approximately 3000 channels of telemetry and video data covering a time period of just 35-55 milliseconds. 
As for the Launch Pad itself, our teams are now investigating the status of SLC-40.  The pad clearly incurred damage, but the scope has yet to be fully determined.  We will share more data as it becomes available.  SpaceX currently operates 3 launch pads – 2 in Florida and 1 in California at Vandenberg Air Force Base.  SpaceX's other launch sites were not affected by yesterday's events.  Space Launch Complex 4E at Vandenberg Air Force Base is in the final stages of an operational upgrade and Launch Complex 39A at Kennedy Space Center remains on schedule to be operational in November.  Both pads are capable of supporting Falcon 9 and Falcon Heavy launches.  We are confident the two launch pads can support our return to flight and fulfill our upcoming manifest needs.
Again, our number one priority is to safely and reliably return to flight for our customers, as well as to take all the necessary steps to ensure the highest possible levels of safety for future crewed missions with the Falcon 9. We will carefully and thoroughly investigate and address this issue.

A Misfire for Space X

SpaceX defines its Falcon 9 as "a two-stage rocket designed and manufactured by SpaceX for the reliable and safe transport of satellites and the Dragon spacecraft into orbit."  That was not the case on Friday when a Falcon 9 rocket exploded shortly after taking off from the company's McGregor, Texas, flight facility.  CBS News reported this explanation from SpaceX:

Earlier today, in McGregor, Texas, SpaceX conducted a test flight of a three-engine version of the F9R test vehicle (successor to Grasshopper)...During the flight, an anomaly was detected in the vehicle and the flight termination system automatically terminated the mission...Throughout the test and subsequent flight termination, the vehicle remained in the designated flight area. There were no injuries or near injuries. An FAA representative was present at all times.

The Falcon 9 is scheduled to launch the Dragon with another set of supplies to the International Space Station on September 19th.  There is no reason to believe this test of a new system will impact the planned launch for NASA.  I should add that SpaceX has plenty of good news to report, as reported in the press releases on its website earlier today (see below), and yet is strangely silent on this latest incident. 

  • August 6:  SpaceX Launches Asiasat 8 Telecommunications Satellite to GTO
  • July 31:  SpaceX Launches 3D-Printed Part to Space, Creates Printed Engine Chamber
  • July 14:  Falcon 9 Launches ORBCOMM OG2 Satellites to Orbit

 NASA and others did not get where they are without costly losses.  This is part of the process. Let's just hope Congress understands this as well.

Update: SpaceX was back in business on September 7 with the successful launch of an AsiaSat 6 communications satellite from Cape Canaveral.
