I’m Anthony Colangelo.

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

The ISS is Getting New Solar Arrays

Main Engine Cut Off

In what seemed to be surprising news to almost everyone I’ve seen mention it (including me), new solar arrays will be headed up to the ISS starting this year. They will sit on top of the existing arrays so as to take advantage of existing capabilities like sun tracking and power distribution.

Episode T+178: Andrew Jones, on China’s Chang’e-5, 2021 Plans, and More

Main Engine Cut Off

Andrew Jones returns to the show for the third time to talk about China’s current missions and future plans, including Chang’e-5, Tianwen-1, the Chinese Space Station, and the international politics surrounding it. And then we dig into the Chinese commercial market a bit—launch companies and remote sensing companies are raising a ton of money, but it’s not yet clear what effect that will have on the global market.

Thank You to December Supporters!

Main Engine Cut Off

Very special thanks to the 496 of you out there supporting Main Engine Cut Off for the month of December. MECO is entirely listener- and reader-supported, so your support keeps this blog and podcast going, growing, and improving, and most importantly, it keeps it independent.

Chang’e-5 Orbiter Begins Extended Mission

Main Engine Cut Off

Chang’e-5 follows in the footsteps of Chang’e-2 and Chang’e-5 T1, which all went on to have interesting and sometimes unexpected extended missions. It feels a little like finishing a mission in Kerbal Space Program and realizing you brought along way too much fuel.

Artemis I Orion PDU Will Not Be Replaced

Main Engine Cut Off

All in all this seems like the right call. At a certain point, the risk of bigger delays coming from the process of fixing this issue is more than the risk on this particular flight. We have yet to see political support of Orion and SLS be eroded in any meaningful way, but every increasing delay has to catch up at some point.

NASA On Ramps New Glenn to NLS II, While Vulcan Slips to Late 2021

Main Engine Cut Off

I mentioned some of this in a recent podcast episode, but considering how long it will take to get BE-4 production up to the point of supporting multiple Vulcan flights alongside the first New Glenn flights, and considering that we have heard little to nothing on the BE-3U front in quite a while, it sure seems like we’re still at least 2 years out from New Glenn’s first flight.

Episode 37 - Go Behind Wendy’s


Jake and Anthony are joined by Tim Dodd, the Everyday Astronaut, to talk about Starship SN8’s epic flight test, Tim’s trip to Boca Chica, and to unveil the 2020 Off-Nominees and crown the winner.

Episode T+176: The Flight of Starship SN8

Main Engine Cut Off

Starship SN8 took flight last week on a mostly-successful mission to test its final descent phase. I share some thoughts on the test, the state of Starship development, and what that all means for the near future of Starship.

Astra, Relativity, and Firefly Win NASA Venture Class Launch Services Contracts

Main Engine Cut Off

These three launch providers will be of great interest to NASA if and when they get flying regularly. NASA would like to not only help provide payloads and incentive to get them flying, but to also have a foot in the door early to start understanding their work, their capabilities, and maybe a bit of what’s going on behind the scenes at these companies. Relatedly, I’m slightly concerned about what they’ll find at Firefly, because something seems to be up there.
