Virgin Orbit confirms that LauncherOne has reached orbit

Electrodynamic tether project from Michigan especially caught my eye. A thin wire connecting two spacecraft in orbit. When electrified, the current interacts with the Earth's magnetic field to create propellant-free propulsion ;)

We'll cover this in more detail in this week's Orbital Index (https://orbitalindex.com), but the gist is that Virgin Orbit now joins SpaceX and Rocket Lab in the elite club of NewSpace startups that have actually made it to orbit. (Also in this club, albeit likely with significant Chinese military tech transfer, are iSpace and Galactic Energy. And we're ignoring "old space" companies like Arianespace, Mitsubishi Heavy Industries, and ULA.)
It's hard to see how the market can support so many small launch providers. That's a lot of options for what has been relatively small market. Rocket Lab's Peter Beck has said some of these companies are propped up by the favorable fundraising environment and to expect industry consolidation when the money runs out.
Rocket Lab is obviously in a great financial position with their high launch cadence and improving re-usability technology. And SpaceX is of course in a league of their own.
The small- and tiny-sat market is expected to grow by a factor of four compared to the previous decade [0].
Big launchers like Falcon 9 and especially Starship cannot easily service this market. Ride share has plenty of issues and projected launch costs of $2M for Starship are on the theoretical side of things right now.
SpaceX needs to set aside a considerable amount of their launch capabilities for internal purposes (i.e. Starlink) and with expected double-digit grow rates in the small-sat market, there's plenty of room for competition.

Still I'm thinking Starship once operational could service that as well, being full RLV. Like, just launch with couple tons of cubesats and as much fuel as possible, then deliver then to orbit as needed using you huge delta-v budget then go home. Rinse and repeat. You could theoretically even do inclination changes using the Starship aerodynamic surfaces if you were crazy enough. ;-)
As you are effectively using up just fuel in Starship (+ some wear and tear) it might still be cheaper than dumping a complete small non-reusable rocket.
Rocket Lab, Virgin Orbit and SpaceX Falcon use keralox (re-usable, with some coking issues), and Blue Origin and SpaceX Raptor uses methalox (cleanly re-usable).
All those providers (except Virgin as far as I know) are pursuing re-usability and SpaceX and Rocket Lab are succeeding at recovering the first stage (with SpaceX far ahead at actually re-using them).
Do they even need to?
Material cost of solid fuel ICBMs go right into few megabucks each.
Reuse is taking over the launch market. And for good reason: expendable aerostructures cost basically the same to build as reusable ones, certainly within a factor of 2 or whatever. A cruise missile and a similar dry mass general aviation aircraft cost about the same.
For all the talk about (& investment in) low cost expendables, nobody has made it cheaper. Besides, reusable liquid rockets are easier on the payload (less vibration, etc).
Reminds me of that infamous Fight Club quote:
> When deep space exploration ramps up, it'll be the corporations that name everything, the IBM Stellar Sphere, the Microsoft Galaxy, Planet Starbucks. [0]
That aside, does Virgin Orbit have anything to do with Virgin Galactic? I vaguely remember Chamath talking about Virgin Galactic's commercial market opportunities when shilling his SPAC, but nothing directly about Virgin Orbit.

> Now Virgin Galactic officials have decided to break off the satellite launcher program and make it its own company. Called Virgin Orbit, the California-based firm is seeking to enter a market that has attracted a lot of interest in recent years as satellites, once huge and expensive, have shrunk in size and cost.

Virgin Galactic has been working on their sub-orbital rocketplane since 2004 and they have yet to fly any paying customers. For something that should have been "just like Space Ship One but bigger" it has been taking ages and might not make much sense if they ever get it working (eq. you might as well buy a seat on a proper commercial Dragon orbital flight).
It mainly seems to be a sort of playground for (originally) Bert Rutan to inadvertently prove that his ideas about planes and low-tech systems don't really translate to this sort of application. Nice work if you can get it, maybe.
Thank you for attending my TED rant.
Also it will need quite substantial solar panels, that add considerable drag, which is doble problematic on these relatively low orbits.
But Jeff Bezos' Blue Origin hasn't yet. We'll see if their Gradatim Ferociter (Step by Step, Ferociously) approach pays off in the longer term.
You're probably thinking of Amazon's house brand approach, which is funny to imagine in this context.
That's the joke =p
I’m very happy for them. The more competition we have in this space, the better. (pardon the pun)
The main benefit is huge flexibility in launch azimuth and conditions (as you can just fly the plane to the best spot to reach the target orbit) and the lack of upkeep for a spaceport. You might even be able to work around bad weather by having multiple drop-zones ready.
