Episode T+31: ULA’s RocketBuilder

Main Engine Cut Off

Tory Bruno took to the stage to announce RocketBuilder, their new way to market and sell Atlas V launch services. I discuss my initial thoughts about it and what the announcement means for ULA going forward in the commercial market.

Episode T+28: The Future of NASA and the Moon

Main Engine Cut Off

NASA released an RFI for small scientific payloads bound for the lunar surface, meant to “address strategic knowledge gaps” associated with human missions to the Moon. I talk about how this could indicate a shift of the SLS/Orion roadmap, and how NASA may be focusing on lunar surface missions in order to build more political capital for the program of record.

Episode T+26: OA-5, Antares, and Orbital ATK’s Road Ahead

Main Engine Cut Off

I took a trip down to Wallops Island, Virginia this week for the launch of OA-5—the return to flight for Antares, sending Cygnus up to the ISS on a resupply mission. I recorded this episode on the long drive home afterwards, and talked about what Antares’ return means for Orbital ATK and what their future may hold—both good and bad.

Episode T+25: Falcon 9 Updates and the 10% Discount

Main Engine Cut Off

Gwynne Shotwell, President of SpaceX, spoke at two events and dropped some tidbits about the Falcon 9 investigation, future versions of the vehicle, and what kind of discount they would offer for “flight-proven” stages. I break down the new info, and discuss their reusability discount.
