I’m Anthony Colangelo.

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

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.

Random Antares Media Day

Main Engine Cut Off

I’m still not quite sure what to make of the random Antares media day that took place Monday at Wallops. They’re three months out from OA-8 and had nothing particularly newsy to announce. Cygnus isn’t integrated and viewable yet, as has been the case for past events like this.

What GSLV-MK3 Means to India

Main Engine Cut Off

Last week, while I was heading to the keynote at Apple’s WWDC, India successfully launched their new vehicle, the Geostationary Launch Vehicle Mark 3. Sridhar Narayanan wrote an incredibly-detailed article for The Planetary Society that I highly recommend reading. It’s a great history of India’s program, a great overview of where they are today, and really gives you perspective on what this launch means for them.

LC-39A and SLC-40 Operating in Parallel

Main Engine Cut Off

This info from Koenigsmann means one of two things: they can complete the work while continuing to fly missions from 39A, or they plan to push the work to the end of the year to give themselves some time with two east coast pads operational.

Thanks to May Patrons

Main Engine Cut Off

Thanks to my patrons for the month of May. 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.

Final Design

Flight Control Final Design

After months of learning and experimenting with circuitry, software, 3D design, and printing, I’ve completed the final layout and design of my Kerbal Space Program controller.

Part of the Flight Control collection.

Episode T+48: Rand Simberg

Main Engine Cut Off

Rand Simberg joins me to talk about his recent trip to the Space Tech Expo, the dawning of the age of in-space manufacturing, the future of SLS and Orion, the National Space Council, and a lot more.

Thoughts on XS-1

Main Engine Cut Off

Overall, I’m quite disappointed at the missed opportunity XS-1 presented to widen the industry. It’ll take a lot to convince me that a Boeing project of this sort will ever be affordable. Boeing doesn’t have the best reputation for cost-efficiency when it comes to launch vehicles—Delta IV and SLS being the two most recent examples—and their last small launch DARPA project didn’t end well.

NASA OIG Questions Marshall Test Stands

Main Engine Cut Off

Things people usually shout “Pork!” about are usually defensible in some way. The prime contractors for SLS are the same old insiders, the work is centralized in the same old districts, but the vehicle itself is still politically defensible as a unique capability the market does not (yet) provide. But this situation is a pretty blatant, indefensible example of the North Alabama Space Agency.
