The space agency specified that the winning proposal must demonstrate an affordable concept beneficial to RLEP, according to the document that asked NASA centers to submit suggestions for the secondary payload. NASA specified that the secondary payload mission should cost no more than $80 million. NASA also required that the payload mass not exceed 2,205 pounds (1,000 kilograms).
