I’m Anthony Colangelo.

I host Main Engine Cut Off and Off-Nominal.

Formerly: Quirks & Compulsions and The Multilogue.

Episode 100 - Astronaut Astronaut


Jake and Anthony are joined by Christian Davenport of The Washington Post to catch up on all the space news, and to celebrate 100 episodes of Off-Nominal.

Episode 99 - Open-Box Protons


Jake and Anthony are joined by Mark Albrecht, executive secretary of the National Space Council from 1989 to 1992, and President of International Launch Services from 1999 to 2006, to talk about his career in space and space policy, the new era of the National Space Council, and more.

Episode T+241: ULA on the Market

Main Engine Cut Off

Eric Berger has three sources saying United Launch Alliance is being shopped around the market right now, so I kick around some thoughts on who may buy ULA, if an offer comes to fruition.

Episode T+240: NSSL Phase 3, and a New Glenn Check In

Main Engine Cut Off

The Space Force rolled out the draft RFP for Phase 3 of the National Security Space Launch program, and it looks pretty good! Elsewhere, NASA selected New Glenn to launch ESCAPADE in 2024, so I check in on the state of things over at Blue Origin—as always, it’s about the engines.

Episode 96 - Lori’s Mom’s Favorite


Jake and Anthony are joined once again by Lori Garver, former NASA Deputy Administrator, to talk about the newest class of Brooke Owens fellows, what she’s been up to lately, and who knows, maybe we’ll randomly argue about commercial space stations on this one, too.

Episode 95 - Horsesh


Jake and Anthony are joined by Eric Berger, Senior Space Editor at Ars Technica, to talk about Super Heavy’s static fire, Progress doing its best Soyuz, and to somewhat randomly argue about Commercial LEO Destinations.

Episode T+239: Space Policy with Lori Garver

Main Engine Cut Off

Lori Garver, former NASA Deputy Administrator, joins me to talk about a whole host of space policy topics, including Artemis and lunar politics, the legacies of Commercial Cargo and Crew, the status of Commercial LEO Destinations, and also Lance Bass.
