#8 – Rocket Lab's Lachlan Matchett on democratising access to space and the Rutherford rocket engine

In this episode I am talking to Lachlan Matchett, who is the VP of Propulsion at Rocket Lab. Rocket Lab is a startup rocket company with the mission of removing barriers to commercial space by frequent launches to low-earth orbit. The current conundrum of many space technology companies that want to launch small satellites into space, is that there is no dedicated launch service tailored to their needs. This is where Rocket Lab enters the picture. To provide small payloads with a flexible and dedicated launch vehicle, Rocket Lab has developed the Electron rocket. The Electron is a two-stage rocket that can be tailored to unique orbital requirements and provides frequent flight opportunities at personalised schedules.

In terms of the engineering, there are many interesting features to the Electron rocket, but one of the key innovations is the Rutherford engine that Lachlan Matchett and his team have developed over the last five years. Rutherford is the first oxygen/kerosene-powered engine to use 3D printing for all primary components. In fact, the Rutherford engine can be printed in an astounding 24 hrs, and this is one of the driving factors behind Rocket Lab's cost efficiency and high target launch frequency. So in this episode, Lachlan and I talk about:

• Rocket Lab's business model
• their recent launch success in Jan 2018
• some of the engineering highlights of the Rutherford engine
• and Rocket Lab's plans for the future
