I’m Anthony Colangelo.

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

Astrobotic to Fly on First Vulcan Flight

Main Engine Cut Off

I could pretty much copy and paste my thoughts from last week about Dream Chaser flying on Vulcan: not surprising news since we had expected Atlas V, and I wonder what will happen if Vulcan doesn’t get to be a part of the next round of Air Force contracts.

Orbital Services Program-4 RFP Released

Main Engine Cut Off

This is a big deal for the Air Force, with a lot of missions up for grabs for launch vehicles that can send 180 kilograms or more to orbit. It’s not the huge payloads like NSSL flies, but 20 missions for the most vibrant sector of the launch market is just as interesting to me.

Dream Chaser to Fly on Vulcan

Main Engine Cut Off

It’s better news for ULA than it is for Sierra Nevada, but it’s not quite the type of commercial contract that we’d need to see for Vulcan to be a standalone success.

Anthony Colangelo Keeps Looking Up

Big Cartel

By day, Anthony Colangelo develops the Big Cartel for iOS app, programming features that allow store owners to conveniently sell work right from their iPhones and iPads. By night, chances are the 28-year-old is geeking out about space.

Episode 22 - The Dark Lord


Eric Berger of Ars Technica joins Jake and Anthony to talk about his recent trip to Boca Chica for Starhopper’s first hop, propellant depots, NASA policy, Artemis, and the passing of his friend, Chris Kraft. Upcoming meetup! Hang out with Jake, Pat (creator of RocketLaunch.Live), and other fellow Anomalies in Kent, WA on August 31! Details at events.offnominal.space.

SpaceX, Arianespace Smallsat Rideshare Flights

Main Engine Cut Off

A pair of interesting smallsat rideshare announcements this morning: Arianespace announced their first (of many?) direct-to-GEO flight opportunities, and SpaceX began advertising—with pricing—the first 3 annual flights to a 600 kilometer sun-synchronous orbit.

Thanks to July Patrons

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.
