Does SpaceX Need to Adjust its Priorities?

Op-ed: We love you SpaceX, and hope you reach Mars. But we need you to focus, Ars Technica

"I understand SpaceX has a master plan--the company wants to colonize Mars. It has been brilliant to watch the plan unfold as SpaceX has used NASA contracts to bootstrap up to the Falcon 9 rocket and used Falcon 9 flights to simultaneously test reusability and supersonic retropropulsion for the Martian environment. I mean, it's genius. But at some point you have to focus on the here and now, and that is the Falcon 9 rocket. The Falcon 9 rocket lies at the core of everything SpaceX wants to do. It delivers commercial satellites and cargo. It will deliver astronauts into orbit. Three Falcon 9 boosters will power the Falcon Heavy. It is the basis of proving the reusability of orbital launch systems. So if there is no Falcon 9, there is no business. And now there have been two failures in 15 months. While the cause of the second failure is not known to outsiders, and it may have been caused by ground systems rather than the rocket itself, the company has nonetheless lost two of its rockets and associated payloads in 15 months. That is sobering."
