SpaceX found the cause of the Falcon 9 explosion and is able to fix it and get back into space in Fall.
Stark Industries has solved another crisis. Elon Musk aka Iron Man announced yesterday in a brief phone call the preliminary findings about the cause of the explosion of a Falcon 9 rocket on June 28.

The cause of the disaster was a failing strut. It is not a complicated piece of technology, but rather simple piece of metal.
Several hundred struts are on every Falcon 9 vehicle, with a cumulative flight history of several thousand. The strut that failed was designed and material certified to handle 10,000 lbs of force, but failed at 2,000 lbs, a five-fold difference.
The failure of the strut lead to the overpressure event in the upper stage liquid oxygen tank that lead to the explosion of the rocket and the attached Cargo Dragon spacecraft.
SpaceX will not use this type of struts in future missions. 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.
Despite SpaceX noting that the findings are preliminary they sound very conclusive. The engineers are though not done with the investigation. The important aspect is that SpaceX has found the cause and knows how to fix it.
After three weeks of investigations, the private space venture of Elon Musk can get back on track and prepare for the next mission.
SpaceX expect to return to flight this fall and fly all the customers we intended to fly in 2015 by end of year. Elon Musk also said that the timeline of the Crew Dragon mission has not been compromised by the incident.
SpaceX handled the situation pretty well and appeared to be very focused. The only issue was the too optimistic Tweet of Elon Musk announcing the findings to be revealed a week earlier than it actually happened.
