NASA is reported to have awarded a further five Dragon cargo flights to SpaceX in December 2015 as a further addition to its original Commercial Resupply Services CRS-1 contract which was originally signed in 2008. The new five missions to resupply the International Space Station were added to the current CRS-1 total of 15 flights. The original 12 mission order in the CRS-1 contract had further three flights added last year. Each flight is valued at circa US$150 million.
