I’m Anthony Colangelo.

I write frequently at Main Engine Cut Off and, occasionally, right here.

Artemis I Orion PDU Will Not Be Replaced

Main Engine Cut Off

All in all this seems like the right call. At a certain point, the risk of bigger delays coming from the process of fixing this issue is more than the risk on this particular flight. We have yet to see political support of Orion and SLS be eroded in any meaningful way, but every increasing delay has to catch up at some point.

NASA On Ramps New Glenn to NLS II, While Vulcan Slips to Late 2021

Main Engine Cut Off

I mentioned some of this in a recent podcast episode, but considering how long it will take to get BE-4 production up to the point of supporting multiple Vulcan flights alongside the first New Glenn flights, and considering that we have heard little to nothing on the BE-3U front in quite a while, it sure seems like we’re still at least 2 years out from New Glenn’s first flight.

Astra, Relativity, and Firefly Win NASA Venture Class Launch Services Contracts

Main Engine Cut Off

These three launch providers will be of great interest to NASA if and when they get flying regularly. NASA would like to not only help provide payloads and incentive to get them flying, but to also have a foot in the door early to start understanding their work, their capabilities, and maybe a bit of what’s going on behind the scenes at these companies. Relatedly, I’m slightly concerned about what they’ll find at Firefly, because something seems to be up there.
