H+ Magazine has a Q&A interview with Randa Milliron, CEO of Interorbital Systems:
h+: Let’s start with the basic question: What are you guys doing?
RANDA MILLIRON: We’re building a low-cost transportation system from Earth to Low Earth Orbit (LEO) and beyond, principally with the Moon as the next logical destination. Let me stress that this is actually a low-cost system — our rocket is not a rehash of a Delta or a kluge of leftover military missile hardware that the manufacturers say will be cheaper just because they want it to be. In reality, the other rockets are still the same intricate and expensive launchers that — by their very complex nature — will never be able to meet our price. We are building an entirely new launch vehicle — one that is the result of a philosophy of radical systems simplification. One that really is low-cost.
The NEPTUNE 30 is an evolved version of the OTRAG (Lutz Kayser, Wernher von Braun, Kurt Debus) launch vehicle design that showed so much promise in the late 1970s. We have a program based on their original work. Our NEPTUNE 30 rocket has been created to carry on their very sound design philosophy and tradition. The launcher is updated and modernized in terms of electronics and computer systems, but the basic tank cluster configuration and the use of storable propellants harks back to Lutz Kayserâ€™s original work. We are lucky enough and honored to have Lutz on the Interorbital team.
