Main Engine Cut Off

NASA selected the organizations who will be carrying out mission design studies for the Mars Sample Return rethink, and the US Space Force selected the first 3 bidders for the National Security Space Launch Program Phase 3 Lane 1.

United Launch Alliance’s Vulcan debut went smoothly, but sluggish hardware integration raises doubts about meeting commitments, while Orion faces heat shield issues, potentially shaking up the Artemis manifest.

I catch up with a round up of stories from January: ULA’s first Vulcan launch, Blue Origin’s success with its BE-4 engines and what it means for their year, Astrobotic’s Peregrine mission, JAXA’s SLIM mission, and NASA’s announcement of Artemis delays.

Amazon moved their Project Kuiper prototypes from Vulcan to Atlas V. Between that and some recent conversations I’ve had, I thought it would be a good time to check in on Kuiper and to see how they’re progressing towards deployment. I do some math, and it’s not good.

After the most recent show, I found a few nuggets of information in the NSSL Phase 3 documents, plus some more updates came out in a call that the Space Force had with some reporters.

Eric Berger of Ars Technica joins me to talk about the budgetary threat facing Mars Sample Return, the latest issue with ULA’s Vulcan vehicle, and the ongoing tweaks to the National Security Space Launch Program’s Phase 3 architecture.

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.

A lot of big, long-running projects have faced delays recently, and it seems like as good a time as any to check in and share some related thoughts. I cover a lot in this one: the Orion PDU issue, Ariane 6, Japan’s H3, Dream Chaser, Vulcan, and New Glenn.
