Commercial Resupply Services (CRS) are contracts awarded by NASA for delivery of cargo and supplies to the International Space Station (ISS) on commercially operated spacecraft. SpaceX signed a contract for 15 launches, the first of which was named CRS-1, and launched on 7th October, 2012.
Subsequent launches were named using step-iteration. However on June 28, 2015, CRS-7 experienced a launch failure, resulting in a 'loss-of-vehicle'.
Presuming SpaceX gets FAA clearance to re-fly the mission, what will the launch be called? What is the protocol followed for naming launches in the events of A) failure with loss-of-vehicle or B) failure with an undamaged vehicle.
In the event that the launch is transferred to another corporation (eg. Orbital Sciences), are the old naming conventions retained?
