Virgin Orbit

Could not find a thread about the company. Launching off a 747, arguably the most beautiful plane ever made ;-), is pretty darn cool. Whether it is a competitive launch provider is a different story, but it does have some things going for it, like the ability to launch from multiple points in the world.

Today is a big day for them, as they are launching to orbit for the first time.
No stream, but updates of this orbital demo here: https://twitter.com/virgin_orbit/status/1264943677975089153?s=21

Scott doing his thing this past week:

They've just taken off as I write this, so we now wait...

 

[dkemme]

Although they had a clean release, something happened, mission terminated but Cosmic Girl and crew safe and returning to base.

 

[Cosmacelf]

Thinking more about this launcher architecture. Haven’t you just introduced the risk of human life loss (747 pilots) into what is normally a human safe process?

 

[e-FTW]

Yup.
It’s like Scott called it in the video above.

I mean how can an av/space geek not love this visual:

I wonder what “terminated” means? Big fireball?

No mention of extreme prejudice, so no.

Possible RUD.

I want to see the picture 1 second after that one with the huge fireball heading towards to the 747

And according to their Twitter feed, they had 2-4 engineers on board.

How much is this different than Air borne missile launchers?

I believe missiles use solid propellant, which is less volatile and finicky than cryogenic liquids. For instance, Virgin Galactic’s tourist rocket ship uses solid propellant.

 

[e-FTW]

I will go out out on a limb and say that the 747 has enough clearance to deal with a RUD from the rocket before they light it up.
This is based on 0 actual knowledge.

SpaceShip2 (Virgin Galactic’s tourist rocket ship) uses a hybrid rocket, solid fuel with a hole down the middle, and LOX for oxidizer. This is so it can be throttled and (theoretically, although I don't think it's been demonstrated) stopped and restarted.
