In the next few days, we’ll start the process of attaching our launch pylon (the “hooks” that secure the rocket to the plane) to #CosmicGirl. Soon after, we’ll conduct our first test flights w/ the pylon before moving on to a series of captive carry flights w/ #LauncherOne.

Maybe to underscore Robotbeats's point, it is soon going to be 20 years since SS1 development began...

According to Scaled Composites, the concept for the program originated in April 1996, preliminary development began in 1999, and full development began in April 2001.

John Fuller, Virgin Orbit: will be integrating LauncherOne pylon with 747 aircraft “shortly”, with captive carry flight campaign to start soon thereafter. #AIAAPropEnergy

In case anyone was confused, you are looking at the launch pylon upside down, as that part needs to be symmetric to mate with the rocket. That part that mates with the aircraft probably isn't symmetric as it needs to fit the left wingbox body fairing area...

Virgin filed for an FCC permit to do some testing on their avionics (1316-EX-ST-2018):
Quote
Explanation of Experiment:
Virgin Orbit LLC (“Virgin Orbit”) is requesting “Special Temporary Authority (STA)” to operate an S-Band
Transmitter in 2200-2290 MHz band. The request is for the ability to sweep across the 2200-2290MHz
band. Virgin Orbit is designing a satellite launch vehicle (“Launcher One”) that will be air launched from a
modified 747 airplane (“Cosmic Girl”). The purpose of requesting an STA license is to analyze the effects
of Launcher One’s S-Band Telemetry transmitter on 747 radios.

and another for testing ground station (1318-EX-ST-2018):
Quote
Explanation of Experiment:
Virgin Orbit LLC (“Virgin Orbit”) is requesting “Special Temporary Authority (STA)” to operate an S-Band
Transmitter at 2262MHz. If 2262 MHz is unavailable Virgin Orbit is open to any frequency within 2200-
2290MHz band. The purpose of the experiment is to test the ability of Virgin Orbit’s Long Beach ground
station to track satellite launch vehicles. Long Beach ground station is receive only and is located at 4022
E Conant St., Long Beach, CA 90808. Virgin Orbit plans to use this ground station for tracking its satellite
launch vehicles. The plan is to fly a small manned aircraft with Quasonix transmitter and antennas around
Long Beach, CA and track that aircraft using the ground station in Long Beach, CA. The transmitter inside
the aircraft will transmit test data at the assigned frequency. Two different data rates will be tested at the
same assigned frequency. Two Antennas might be used in order to get better coverage, in such a case the
signal from the transmitter will be split between the antennas using a 3dB RF splitter.

Ericson: we mated LauncherOne pylon to Virgin Orbit’s 747 last week; first captive carry test flight in the next week.

For anyone who didn't see the follow-on tweets from Jeff...

Quote from: Jeff Foust on Twitter
Clarification: the upcoming flight is an “envelope expansion” flight of just the 747 and its new pylon, rather than a full-fledged captive carry flight with a LauncherOne vehicle attached.

(The snark on this next one wounds me, but in the interest of good and faithful transcription...)

Quote from: Jeff Foust on Twitter
But then, I can recall another Virgin Orbit executive saying at NewSpace 2018 in late June that the captive carry flight was taking place in “a little over a week”, so  ¯\_(ツ)_/¯

[And for clarity, I'll point out again that after that rather botched mis-comminucation, we clarified within hours that it was not indeed the plan...]

Quote from: Jeff Foust on Twitter
Also, that flight is apparently in the “next weeks” and not necessarily next week.


We're making great progress, but we're not flying and never planned to fly a captive carry flight this week.  8)

I post here for fun, but in the interest of full disclosure, I work for Virgin Orbit. That said, I'm an honest fan of pretty much everything space.

Keep up the amazing work guys. LauncherOne & its family will be amazing vehicles. You guys have crawl before you walk. We are here for the ride.

Just for fun, here's a nice air-to-air photo of Cosmic Girl in flight we haven't shared anyone else. =)

We haven't said too much publicly about the pylon in part because, to be honest, in can sound kinda boring to those who haven't worked on it (to us, it's super fascinating, but then again, we are kinda weirdos!), but Guy Norris has a characteristically good write-up in AvWeek for those who want to delve a bit deeper.

an impressive job on the pylon...very nice.  I use to be a test pilot for the folks who built the airplane :) nice work

The 747 flew over our house yesterday on the way back into Long Beach Airport and you could definitely see the pylon on the left wing.  Unfortunately, I wasn't able to get a picture of it.

I note that the Australian "Space Activities Amendment (Launches and Returns) Bill 2018" passed 2 weeks ago specifically includes "licensing arrangements for launches from aircraft in flight".

Could this potentially mean either VG or VO are considering operations over here??
With sufficient thrust, pigs fly just fine - however, this is not necessarily a good idea. It is hard to be sure where they are
going to land, and it could be dangerous sitting under them as they fly overhead.

In the recent Instagram post, you can see the aft of the first stage. A stage with an unshrouded engine bay shows that it's a dual Turbopump GG cycle. Has that information been pointed out yet?


edit: what's peculiar is that the latest stage being worked on seems to have longer tanks, and the more complete stage next to that seems to have the engine clocked at a different angle than the incomplete one.


edit 2: Early testing video clearly shows the second turbopump and  turbine exhaust https://www.youtube.com/watch?time_continue=6&v=TqOzNDYr83s

edit 3: Now that I see the bigger picture it just looks like perspective that makes it look longer.

Too lazy to go through the entire thread. :P

Does anyone know if Launcher One might have a tailcone fairing enclosing the exhaust nozzle bell for aerodynamic drag reduction? Like the AGM-48 Skybolt and the AGM-69 SRAM missiles.

There is no tailcone fairing.
