I’m Anthony Colangelo.

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

Starliner Free Flight (In)Capability

Main Engine Cut Off

It seems that Boeing took Charlie Bolden too literally: his oft-heard refrain was that NASA turned over LEO to commercial companies and wanted beyond LEO to itself. Boeing designed and built a vehicle that literally can not fly beyond LEO without help.

More Details on Sierra Nevada’s Dream Chaser and Deep Space Gateway Concept

Main Engine Cut Off

The ISS R&D Conference is kicking off this week in DC with sure-to-be interesting keynotes by Elon Musk, Robert Bigelow, and a few members of Congress, among others. But there are also a bunch of technical sessions in the afternoons, so I went digging through the agenda. I found two sessions by Sierra Nevada—one on Dream Chaser at the ISS and one on their NextSTEP-2 Deep Space Gateway concept. Lucky for us, the session PDFs are up already.

Episode T+52: XCOR Winds Down, ULA Wins STP-3

Main Engine Cut Off

XCOR laid off the rest of its staff and is closing up shop after losing a contract with ULA, which leaves ULA in an interesting spot for Vulcan-ACES. On the ULA side, they won their first Phase 1A contract from the Air Force, and the contract price sheds some light on just how much they’re cutting their costs.

Scottish Spaceport Proposed

Main Engine Cut Off

I always thought the north side of the UK would be a great spot for a polar launch site. Some will liken this to the spaceport dilemma in the US, but it’s totally different.

JAXA Interested in NASA’s Deep Space Gateway

Main Engine Cut Off

This is exactly what NASA was hoping to achieve by putting the plans for the Deep Space Gateway out into the public eye. They need international and commercial partners to latch onto the idea of the Deep Space Gateway, develop plans to use it, and talk about those plans publicly. That’s how they can build support for it within the US political sphere, and that’s how they can get it funded.

Thanks to June Patrons

Main Engine Cut Off

Thanks to the supporters of Main Engine Cut Off for the month of June. If you’re getting some value out of what I do here and want to send a little value back to help support Main Engine Cut Off, head over to Patreon and donate as little as $1 a month—every little bit helps.

SpaceX Doubleheader

Main Engine Cut Off

Back in April, ULA announced layoffs at Vandenberg, which seemed to indicate that they dropped their launch team on the west coast. Two months later, it looks like SpaceX has two independent launch teams up and running.

Flight of the Aerospike: Episode 1

Main Engine Cut Off

It’s been hard to get a sense of what ARCA has been up to lately, and how seriously we should take this project. But this week, they released the first episode of a new series of videos leading up to their launch of a subscale vehicle powered by a linear aerospike engine.

SpaceX’s Mars V2 Plan

Main Engine Cut Off

Scaled hardware to validate the architecture, big enough for initial Mars missions with a few crew members, and small enough to be used commercially for other tasks.

S7 Orders 12 Zenit Vehicles

Main Engine Cut Off

I’m very curious to see how the second life of Sea Launch will play out. Relatedly, I haven’t been too kind to Antares lately, but this is actually good news for Orbital ATK.
