What Interorbital Systems does
Interorbital Systems (IOS) is a privately held rocket, satellite, and spacecraft manufacturing company founded in 1996 by Roderick Milliron and Randa Milliron at Mojave Air and Space Port in California. The company is developing two orbital launch vehicles — the NEPTUNE_100 (100-kg payload to 500-km polar orbit, priced at $599,999 per dedicated launch) and the larger TRITON_4500 (4,500-kg payload, $12M per launch) — both powered by proprietary ablatively-cooled liquid rocket engines built via in-house filament-winding composite manufacturing and using storable WFNA/Turpentine propellants. Beyond launch vehicles, IOS sells CubeSat 3.0 and TubeSat 3.0 educational satellite kits (marketed as the lowest-cost professional-quality kits), the LunarStation lunar soft-landing bus ($6M per 20-kg payload), and the CREW MODULE-1 two-passenger orbital capsule ($10M per person), with launches planned from both ocean and land-based mobile platforms.
The business model is one-time sale or service-based across five revenue streams: dedicated and ride-share launch services, CubeSat/TubeSat kit sales, lunar mission services, orbital expedition tickets, and an SEC Rule 506(c) private placement offering up to $12M (with $750,000 already sold as of January 2024). IOS serves a diversified customer base of educational institutions (Stanford, NUS, Morehead State, Tancredo Middle School), space startups (SpaceKidz India, Boreal Space, Synergy Moon), government agencies (NASA IV&V), and wealthy individuals (including lead investor Robbie Krieger and first ticket holder Tim Reed), with 180+ pre-paid customers on the launch manifest awaiting NEPTUNE flights. Go-to-market is direct sales via website, phone, and email, supplemented by demonstration launches and partnerships with Ed Belbruno (NASA JPL orbital mechanic) for lunar trajectory design. The company has 1-10 employees and remains pre-commercial on its own orbital launches despite nearly three decades of development.
