Ball crawl instead of bouncy house, and color coded! Won't they need to conduct this test in a vacuum chamber? I doubt testing it during a launch would be cheaper than testing it on earth.

But they *are* testing it on Earth, just not with the fidelity you seem to want. They might also do a vacuum chamber test, but note that even that is an imperfect analog.

Looking back at X-15 videos, it appears that the rocket ignites before release...

No, not until after drop

When it is released from the wing, it should be decelerating until rocket engine ignites... that pushes the propellants forward to the 'top' of the tanks.  What is done to 'settle' the liquids before engine ignition?

Angle the vehicle slightly upwards. That should counter the drag going forwards and settle the propellants to the bottom of the tanks.
I got the impression, from various design studies that flight angle at separation can make a huge difference in several areas regarding loads, payload to orbit etc. Like MR control during the flight, one of those subtle-but-powerful details that can have a big impact on the feasibility  of a design.
BFS. The worlds first Methane fueled FFORSC engined CFRP structured A380 sized aerospaceplane tail sitter capable of flying in Earth and Mars atmospheres. BFR. The worlds biggest Methane fueled FFORSC engined CFRP structured booster for BFS. First flight to Mars by end of 2022. Forward looking statements. T&C apply. Believe no one. Run your own numbers. So, you are going to Mars to start a better life? Picture it in your mind. Now say what it is out loud.

Dan Hart, Virgin Orbit: saw a tipping point several years ago in growth of smallsat capabilities. But most still relying on secondary payload opportunities.

Hart touts the benefits of air launch, including rapid turnaround; could potentially do a couple launches in a day.

Hart:  our manifest in 2018 is full, half full in 2019 (with 12 launches planned), and half full also in 2020, with double the launches.

Recently, we conducted two Launch Campaign Rehearsals—full-on sessions where our technicians and engineers prepare a LauncherOne rocket as though it were launch day and the countdown clock was ticking towards t-minus-zero.

Propellant tanks are loaded and pressurized, software is loaded up, and our mission control crew are at their consoles, overseeing it all. These rehearsals provide a great chance to test out everything from the ground support equipment to the call-outs and procedures.

It is imperative that we be safe, precise, and systematic. Since we are building a system that is designed for flexibility, it bodes well that our very first launch campaign rehearsal was completed in one extended shift—and even better that our second rehearsal was 40% faster.

There’s still important work to do as we finish qualification of our major assemblies and systems for LauncherOne—but our first orbital flight grows closer with every test and every milestone.

Wow lots to make out in that last photo.  There are several first stages at varying levels of maturity, and an aft skirt with some fins attached to it.  I think there are also some upper stages and interstages towards the back, and a fairing half.  Seems like enough components for 2 or 3 vehicles.

So, that's what a billionaire backed venture looks like.

The majority of Virgin Galactic and Virgin Orbit's funding comes from Saudi Arabia, not the Virgin parent company (and I doubt any of it comes directly from Branson).

FYI, this is not at all correct. The announcement last year about Virgin and Saudi Arabia was about a potential future investment, which is still subject to a variety of government approvals et cetera et cetera. So, no funding has come in from Saudi Arabia, at least not yet.

You may be thinking of our minority partner Aabar Investments, which is based in the UAE, not Saudi. They and Virgin Group (which has most definitely put in funding directly!) have been our two sources of funding.

And yes, it is certainly nice to work for investors who enable us to be hardware rich!

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.

Virgin Orbit aims to offer responsive launch and constellation maintenance services

SAN JOSE, California – Virgin Orbit plans to offer customers a variety of services including responsive launch, maintenance of large satellite constellations and potentially debris removal, Dan Hart, Virgin Orbit president and chief executive, said April 4 at the Space 2.0 conference here.

In 2018, Virgin Orbit plans to conduct the first test launch and initial commercial flight of LauncherOne, its air-launched rocket designed to send payloads weighing 300 kilograms into sun synchronous orbit and 500 kilograms into low inclination orbits. Some customers will fill LauncherOne’s fairing with a single satellite while other customers will launch multiple satellites on the rocket, Hart said.

As Virgin Orbit meets with potential commercial and government customers, the company is beginning to define what it calls “concierge service to orbit,” Hart said.

For larger constellations, Virgin Orbit is “under contract to do operations and maintenance,” Hart said. “The satellite constellations that have hundreds or thousands of satellites will send them up on large rockets. Then, as the satellites age or there’s infant mortality, there will be a need to replenish satellites at various planes.”

At that point, it would be inefficient for the constellation operators to purchase a larger rocket or ride as a secondary payload, Hart said.

“If you need to put two satellites in a plane, you are going to waste a lot of money buying a large rocket or spend a lot of time drifting over a hitchhiked satellite to your orbit,” Hart said. “So there’s a lot of interest from those companies in dedicated launch capability.”

Virgin Orbit plans to serve those large constellations by “putting up spares, servicing specific planes and potentially handling debris if it shows up in their orbit,” Hart said.

Hart said that until recently he didn’t see much of a business case for space debris removal, but that is changing with the number of satellites people plan to send into low Earth orbit.

“There will be a real need to clear out debris in low Earth orbits if satellites have issues in their orbital slots. And with thousands of satellites planned, that is going to happen,” Hart said. “I’ve recently become a believer that space debris is a problem that needs to be solved and I’m happy to see there are companies rising up to take that on.”

A key element of Virgin Orbit’s concierge service will be flexible and responsive space access, Hart said. LauncherOne flies off the wing of a modified Boeing 747.

“Commercial customers say the idea of getting into orbit within days is very appealing for them,” Hart said. “For national security world, that has always been a goal. For once, the commercial and government worlds are perfectly well aligned.”

Initially, Virgin Orbit’s 747, called Cosmic Girl, will fly from the Mojave Air and Space Port in California and “we are planning to fly out of the Kennedy Space Center,” Hart said. “As the industry matures and people want to go to different orbits, we can fly out of pretty much any airport that can handle a 747. Of course we have to handle some propellant as well and licensing and so forth.”
