I’m Anthony Colangelo.

And here’s the megafeed of everything I’ve been doing.

IEEE Spectrum’s Project Moon Base

Main Engine Cut Off

IEEE Spectrum published a fantastic collection of stories and features on the current trend of Moon missions. I’ve had a hard copy in my office that I’ve been reading over the past week or so, and it’s a great read for you, the super enthusiast, or your non-space-obsessed friends.

Episode T+126: The NASA Ousters

Main Engine Cut Off

Two top NASA human exploration leaders—Bill Gerstenmaier and Bill Hill—have been ousted from their positions. I break down what this means for NASA and its plans, where things could go from here, and ponder whether these changes really matter.

Episode 21 - Carpet Bombing Venus


On the 50th anniversary of Apollo 11, Jake and Anthony talk about the aftermath of Apollo and alternate histories we could have seen—the Apollo Applications Program, a crewed Venus flyby, and more Skylab.

Vandenberg’s Lull is California’s Problem

Main Engine Cut Off

The big problem is that it’s painful to get established at Vandenberg because of the environment the state has created there. Head to Cape Canaveral, and Space Florida will actively throw money your way. Head to Vandenberg, and you better watch where you step.

Firefly, IAI to Partner on Beresheet-Derived Lander

Main Engine Cut Off

If the tips I picked up previously about Firefly using Intuitive Machines’ lander were accurate, this is a curious change. The Beresheet-derived lander is probably quite a few years out, though, as the mockups show it stacked on top of a Firefly Beta and it needs that kind of lift to get to the Moon.

Virgin Orbit Drops LauncherOne

Main Engine Cut Off

There hasn’t been much info released about the drop test, but apparently it went well. There still are a few issues to iron out, mostly surrounding the payload environment before it drops off the plane’s wing. Turns out planes vibrate a lot.

Acting Air Force Secretary Weighs In on Space Force Debate

Main Engine Cut Off

Sandra Erwin published an enlightening interview with Matt Donovan, Acting Air Force Secretary, where he shares his thoughts on the Space Force debate publicly for the first time. It’s a notable interview because he was the undersecretary of the Air Force for the past two years, yet we heard nothing from him through that time.

NASA Awards IXPE Launch to SpaceX for $50.3 Million

Main Engine Cut Off

Boy, is that inexpensive. IXPE is just a few hundred kilograms and is going to a 0° inclination orbit, so Falcon 9 could fit a bit more payload aboard, but not much. I’m going to guess that it will fly solo, and take the title away from FORMOSAT 5 for lightest payload flown by Falcon 9.

Episode T+125: Andrew Jones

Main Engine Cut Off

Andrew Jones returns to the show to update us on China’s various efforts. We talk Chang’e-4 and Yutu-2, the mysterious Long March 5 delay, and what the future of Chinese launch may look like.

Apollo, GAMBIT, and UPWARD

Main Engine Cut Off

If you’re into quirky space history, Dwayne Day wrote an incredible article for The Space Review this week on a NASA/NRO collaboration that never saw the light of day, nor was known about until now.
