I’m Anthony Colangelo.

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

The FCC Might Let 5G (Use Some C-Band)

Main Engine Cut Off

“The unanimous vote by Federal Communications Commission Chairman Ajit Pai and the agency’s three commissioners lays the groundwork for the transition of some, or possibly all of the 500 megahertz of spectrum commonly known as C-band.”

New Glenn Dual Manifesting

Main Engine Cut Off

Blue seems to be trying really hard to limit the downsides of dual manifesting, and a single price for a ride to orbit no matter how you fly or when is a huge departure from the norm. It really only makes sense two ways: the entry price for a ride on New Glenn is shockingly low, or Blue will have no shortage of their own payloads to fly. Or both.

Cygnus Successfully Tests Station Reboost

Main Engine Cut Off

“The Cygnus spacecraft’s BT-4 main engine, supplied by IHI Aerospace of Japan, fired for 50 seconds Tuesday. The engine produces around 100 pounds of thrust, and the maneuver raised the orbit of the roughly 450-ton space station by 295 feet (90 meters).”

AR-22 Fires 10 Times in 240 Hours

Main Engine Cut Off

The total firing duration was about two Shuttle flights to orbit, so total duration isn’t the surprising thing here—it’s the fact that they could turn the engine around quick enough to pull this off. We’ll see where this goes from here, but I don’t have high hopes.

ISRO Carries Out Pad Abort Test

Main Engine Cut Off

Though ISRO doesn’t have an official human spaceflight program just yet, they’re making good progress on fundamental components, including the abort systems and the launch vehicle—GSLV Mk. III. Looks like this was a successful test of the abort system, save for the crew module separating from the parachutes on final descent.

Six of Ten AR-22 Firings Completed

Main Engine Cut Off

I’ve heard that they did lose a day due to weather last week, and have been working around some since, but this is at least somewhat encouraging. I’ve also heard a lot of skepticism about the vehicle that is supposed to be attached to this engine, but I guess we’ll see soon.

FAA Issues Virgin Orbit Launch License

Main Engine Cut Off

Contrary to what was reported in SpaceNews a few days ago, there will be more than one captive carry test, there won’t be a captive carry test next week, and there will be a drop test before the first launch attempt. The test campaign will take most of the summer, so I wouldn’t expect to see engines light until the end of August or even September.

LauncherOne Getting Close

Main Engine Cut Off

Workers will be attaching the pylon that holds LauncherOne to the aircraft’s left wing in the next few days, he said. “If everything goes well there, we’ll conduct our first captive carry test,” he said. The flight will take place from the Mojave Air and Space Port in California.
