We welcomes Randa and Rod Milliron back for this 1 hour 36 minute discussion about their company, Interorbital Systems (IOS), rocket engine development and testing, and much more. Visit their website at for more information and details of topics discussed today. We started out by getting details about the IOS static engine test in Oct. 2012. Our guests talked about the test and described their engine and the Neptune modular launch system. Rod talked about using hypergolic propellants and why they chose to do so, plus our guests went over the capability of the Neptune rocket depending on how many modules and stages were used. They also talked about adding a stage for the lunar lander as they are a GLXP participant. We talked about the GLXP, getting secondary payload rides to the Moon or using a dedicated launcher such as the Neptune. Our guests described their plans for doing a sea launch and why, probably in the Pacific Ocean near Hawaii. They also talked about having spaceport launching capabilities as well. Listeners asked about demo flights and time lines, plus suborbital test flights. Another listener asked about the plans for Olav Zipser to jump from a rocket in light of the Red Bull success. Wes from Tampa emailed in about suborbital flights offering a space view for sensor testing, retrieving payloads, & testing low gravity manufacturing/3D printing. IOS suborbital flights are their test flights. Our guests had much to say about these matters, especially retrievable payloads. Blair emailed in about IOS due diligence, their launch track record, and their consumer sales. We then talked about the IOS personal satellite TubeSat and CubeSat kits. Wes called in to talk about his positive experiences given he has purchased one of the kits. I also asked Wes about his due diligence on IOS before buying the kit. Listen to how our guests and Wes responded to this line of questioning. In the second segment, I asked about engine test regulations & required permits for testing at Mojave. Randa and Rod mentioned complying with ITAR because they have foreign sales of the personal satellite kits. They also talked about a 4H group on the Utah Colorado border building a personal satellite and the educational outreach this involves with the Ute Native Americans and others. The Millirons were asked about their being considered fringe by some in the space community. Note what they said about this and about attending space conferences. A question came in as to why they were not using a hybrid engine. Rod had lots to say about hybrids, don't miss his comments. Our discussion concluded with a summary of their forthcoming rocket plans and development program. Please post your comments/questions on The Space Show blog.
