I’m Anthony Colangelo.

Inmarsat, under regulatory pressure to get flying, decided to take a mid-2017 launch slot on Ariane 5, moving away from Falcon Heavy. Everyone thinks it’s a big deal, but for the wrong reason. And SpaceX’s Commercial Crew flights have been delayed, but we did find out that NASA’s Safety Technical Review Board approved their plan to load crew before fueling. That is a big deal.

A Progress launch failed on its way to the ISS, so I discuss how this may affect the politics of the ISS and NASA going forward. And then I get into some thoughts on satellite servicing in general, and specifically surrounding Restore-L and Orbital ATK’s Mission Extension Vehicle. This episode of Main Engine Cut Off is brought to you by 3 executive producers—@spacepat_o, Matt Giraitis, and one anonymous—and 25 other supporters on Patreon.

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.

All signs point to SpaceX nearing a return-to-flight mission for Falcon 9. I discuss what to watch for in the months ahead, and read some email.

Following up on last show’s topic, there are signs that NASA may be moving away from Orion in the future. I discuss how I see NASA modernizing their exploration roadmap, politically, in the next administration.

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.

In light of the recent Schiaparelli lander failure, I discuss the differences between missions supported by financial and political capital, and how those differences will play out in the next era of space exploration.

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.

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.

After a few busy weeks of Blue Origin and SpaceX news, I spend some time talking about ULA’s RapidLaunch program and how they are working to get competitive within the commercial market.
