Main Engine Cut Off

Northrop Grumman was awarded $187 million for the Gateway Habitat design, which caps off NASA’s 2020 budget work for Artemis components.

We take a look at the Artemis program’s acquisitions so far and the road ahead under Lueders’ leadership.

How NASA’s Reliance On Commercial Companies Is Shaping Space Exploration

Are We There Yet?

NASA is relying more and more on the private sector to help its exploration efforts — from building the next moon lander to transporting astronauts to the International Space Station.

So what does the future look like for this new dawn of commercial exploration? We’ll talk with Main Engine Cut Off podcast host Anthony Colangelo about the latest space business news and how leveraging commercial companies will help NASA reach places like the moon and Mars.

Origins: Jim Bridenstine


NASA Administrator Jim Bridenstine joins Jake and Anthony for the first episode of Off-Nominal Origins. We talk about how he got interested in space and aviation, his time at Rice University, his years as a Navy pilot, his continuing fascination with the Rocket Racing League, and a whole lot more.And yes, obviously, we talk about the time Jake and Anthony started a weird little sideshow at IAC 2019 with The Jim Bridenstine Fan Club.

Donation Campaign Update!


Jake and Anthony stop by with a quick update on our donation campaign to help two wonderful organizations, Black Girls Code and the Banneker Institute. The response has been incredible so far, so let’s keep it up!

Let’s Make Space Better.


Here at Off-Nominal, we've been following the demonstrations against racial inequality and police violence in the United States, Canada, and around the world with concern. These events have highlighted deep problems with how we treat each other in many domains, and space exploration is not exempt.While we have been processing this in real-time, it has become obvious that we must do our part and use our platform to speak up against these inequalities and take action to stop them. We have been engaging with our Discord community this past week to come up with a plan.

Episode T+158: Doug Loverro Resigns, and a Bit About the Artemis Accords

Main Engine Cut Off

The head of human spaceflight at NASA resigned last week, just before the most important crewed launch the agency has seen in a decade. However, it appears as though the resignation is related to the Artemis program and its landers. I give some thoughts on the implications of the departure, and also cover a recent development in international space politics—the Artemis Accords.
