Your Hosts: Howard, Mary Robinette, and Dan, with special guests Bart Smith and Ben Hewett When we talk about space travel we're usually talking about rocket scientists and astronauts. In this episode we spoke with our guests Bart Smith and Ben Hewett, about the "unsexy" (read: possibly boring but don't be deceived) side of the space program—budgeting, logistics, and procurement. RFI and RFP, with toilets, hammers, and business cards; that's this episode. (For those unfamiliar with the above TLAs [three letter acronyms], RFI and RFP stand for Request for Information and Request for Proposal.)
