The electron is a really cool rocket. It's constructed using carbon composite tanks and uses Rocketlab's Rutherford engine. The engine is constructed using a large amount of 3d printing and uses battery powered electrically driven fuel pumps.

It's worth mentioning that while electric turbopumps are a lot better that pressure-fed designs, for larger engines they aren't as effective as using pre-burners (due to the weight of the batteries).

It does make the design much simpler, though.

I met Peter Beck (CEO/founder) at SmallSat 2014. Hat-tip for doing what he set out to do. He told me that a Ferrari was not much more than a bunch of carbon fiber, software, and fuel--and only costs $500,000. So there is no reason that a small rocket, which is also carbon fiber, software, and fuel, can't also be $500,000. Now that his launch vehicle is orbital, I'm looking forward to it someday being a half-million-dollar launch vehicle.

Minor quibble: The company is over ten years old; I don't think it's quite a startup anymore.

Though the launch was only a test, Rocket Lab managed to launch three satellites into orbit for tracking shipping, weather and imaging.

Orbital class rocket, not bad. Also, made it to orbit on the second attempt, beat Spacex by two launches :P The Rutherford engine sea level Isp of 303 on RP1/LOX is damn impressive.

Isp is awesome, TWR... not so much. The electric turbopumps are a big propellant efficiency win, but aren't without other costs.

They haven't made their first commercial launch yet. They've certainly received money for scheduled launches in the future, but I'd say they're definitely just getting started.

Some industries have longer incubation periods =)

It's interesting seeing the difference between the publicity that SpaceX gets, and the publicity of other rocket companies like RocketLab get.

It shows how effective the PR machine for SpaceX is. RocketLabs launch is pretty significant, considering it's the first orbital launch of a rocket designed and built in a small nation.

This has barely hit the news. I guess part of the reason is that it's not in the USA, and that New Zealand isn't capable of putting nuclear warheads on top of one, unlike North Korea.

What they’ve accomplished is amazing engineering. I’m sort of scratching my head at the economics though. Their cost to orbit is about $15,000/kg. That’s more expensive than the Space Shuttle was. And the CEO has said they’re not working on reusability.

Their goal of rapid manufacturing and frequent launches seems laudable in an expendable launch vehicle world. I’m not sure how they plan to survive when SpaceX and Blue Origin achieve rapid reusability though.
