How Rocket Lab questions the fundamentals of building both rockets and launch companies – TechCrunch


Rocket Lab CEO Peter Beck has had an eventful couple of years, despite the unpredictable challenges that COVID-19 threw in the path of the rocket maker’s LA and New Zealand-based operations. Just this year, Rocket Lab had its public market debut, revealed its plans for a new medium-lift launch vehicle called Neutron and acquired two companies (on top of its first acquisition from 2020).

I spoke to Beck at our TC Sessions: Space 2021 event where we covered what’s new and special about Neutron, and how it leverages the pedigree of the company’s Electron rockets to challenge some assumptions about how bigger rockets are built. We also dove into his vision for Rocket Lab and what it aims to accomplish in terms of making it even easier for prospective customers to get their stuff to space.

Beck dished on everything from the unique way that Rocket Lab plans to land the reusable first stage of Neutron back on Earth, to the “Hungry Hippo”-type design of the fairing that allows it to avoid being discarded post-use. He also described his vision for what Rocket Lab hopes to become through its built-out of more service offerings, both through acquisitions and in-house product development.

On ditching landing legs and improving aerodynamics:

It’s all about removing as many components and as many complexities as possible [ … ] We had this epiphany one day, where we were like, we’re working on these landing legs, and we’re just going around in circles endlessly with mechanisms, and how are we going to service those mechanisms, and all the rest of it. And then we were like, let’s just stop, and let’s just not have landing legs. So let’s just have a wide enough base, so that we can resist any of the kind of tipping or creeping movements.

So we start off with this big wide base and drew a satellite in the payload and the upper stage top and the fairing diamond, and then just drew two lines that joined it all up, and it looked like a traffic cone. That’s actually the optimum vehicle: It has no legs, it’s just a nice stable kind of structure. And then as we started doing some of the CFD [computational fluid dynamics] on it, and some of the aerodynamics and some of the reentry work, and that traffic cone proved very useful, because you have this decreasing pressure over the length of the vehicle, which means you don’t have any shockwaves attaching to it, which is always a challenge with reentry.

On how to build a space company that actually serves the needs of modern customers:
