> Interorbital successfully test fires its CPM vernier rocket engine! MOJAVE-05.27.2012

Interorbital successfully test fires its CPM vernier rocket engine! MOJAVE-05.27.2012---Two of these small vernier rocket engines provide roll control for a stand-alone Common Propulsion Module (CPM) stage. CPMs are the basic building blocks for IOS' multi-stage bundled modular rockets--as in the NEPTUNE 5 (N5), a five-module orbital rocket. IOS rocket engines are the first US rocket engines utilizing storable high-density nitric acid and turpentine as propellants. In addition to the vernier rocket engine, the series of tests included the verification of the CPM controller. This unit is the interface between the CPM and the user or the guidance software. The test series also verified IOS' rocket launch control software developed to control the launch of the NEPTUNE series rockets. This software allows the use of a laptop computer or tablet computer for simple low-cost launch control. Launch crew training and key ground support equipment were also verified in this series of tests. These field trials were precursors to the 7,500-lb-thrust CPM main engine hot-firings, which will begin soon at the IOS test facilities, located at the Mojave Air and Space Port.
> Interorbital Marks Major Milestone with Rocket Engine Firing! MOJAVE-10.28.2012

On a calm clear high-desert October evening, Interorbital Systems’ NEPTUNE rocket series' main engine roared to life in its first hot-firing test. The engine, the IOS GPRE 7.5KNTA (General Purpose Rocket Engine; 7,500lb-thrust; Nitric Acid; Turpentine; Ablative cooling), blasted a 22-foot (6.71-meter) plume of fire across Interorbital’s Mojave Spaceport test area, scorching the sand an additional 50 feet (15.24 meters) beyond the plume end. The all-composite-chambered 7.5K-pound (33,362-newton) thrust engine is the largest rocket engine in the world utilizing high-density, storable nitric acid and turpentine. These hypergolic propellants provide almost instantaneous chemical ignition. This static firing marks a major milestone in the evolution of the company’s NEPTUNE Modular Orbital Launch Vehicle series. Refining the engine operation paves the way for the first flight test of the CPM---Common Propulsion Module—the stand-alone rocket that is the primary construction element of various bundled configurations that yield launch vehicles specially designed to meet specific mission requirements. IOS’ first orbital launcher is a seven-module rocket designated the NEPTUNE 7 (N7)---a three-stage orbital vehicle powered by seven GPRE 7.5KNTA engines---and purposed to lift a mixed-manifest of some 24 TubeSats and CubeSats on each launch. Interorbital recently completed a NASA Phase I SBIR contract, awarded to further the development of the NEPTUNE Modular Rocket series.

> The CPM Controller Version 2 is complete! MOJAVE-02.27.2013

The Interorbital Guidance and Control team has completed its CPM Controller Version 2 and has updated the CPM Controller remote interface. Each Common Propulsion Module has its own CPM Controller. It receives commands from the onboard guidance computer or from an operator on the ground and executes commands such as the opening and closing of valves or setting the gimbal position for steering. In addition, it collects health data and processes it. Ground control commands can be sent from a laptop or tablet computer. The ignition sequence has been converted from manual to automated.
> Guidance system component nearing completion! MOJAVE-03.18.2013

Interorbital's low-cost, in-house designed inertial measurement unit (IMU), IOSIMU Ver 1, has passed its initial testing phase. IOSIMU Ver 1 is the lowest-cost IMU available today. The remaining components of the NEPTUNE guidance system are nearing completion.
> Interorbital Presents at Google Lunar X PRIZE Summit! SANTIAGO, CHILE-04.04.2013

Interorbital’s CEO/CoFounder Randa Milliron presented updates on Interorbital’s lunar rocket (N36) development from California via Google Hangout with the able facilitation of on-site SYNERGY MOON teammember Bipin Agravat. Interorbital also attended the PISCES CONFERENCE (Pacific International Space Center for Exploration Systems) held at Waikoloa Beach Resort on Hawai’i Island last November. Randa Relich Milliron presented “Interorbital Systems’ NEPTUNE Modular Rocket and Personal Satellite Kit-and-Launch Program: Revolutionizing Low-Cost Space Access.” Roderick W. Milliron presented “Trans Lunar Research: Actualizing Private-Sector Moon Missions.”
> Mission II Payload Status Announced at SPRSA and CalTech Interplanetary Conference, Mojave-06.24.13

Ryerson University of Toronto, Canada, has purchased two TubeSat kits for use in its Space Systems Engineering program, bringing the number of small sats manifested on NEPTUNE Rocket orbital missions to 57! Interorbital announced its launch manifest update at the Small Payload Ride Share Association and Cal Tech Interplanetary Small Sat Conferences in June.
> Interorbital to Launch “TARDIS in Orbit” Sat for DOCTOR WHO’s 50th, Mojave-08.24.13

Whovians and Wholligans planet-wide collaborated to actualize a most fitting tribute to DOCTOR WHO – one of the best and most beloved of all Science Fiction phenomena---for its half-century anniversary: Launching a TARDIS into Orbit---REALLY!!!! As Kickstarter project creators Robert and daughter Alex Doyle would say, “WooWhooo!” Everyone at IOS---also DOCTOR WHO mega-fans---are thrilled to be a part of this ultra-cool global celebration! The TARDIS now has its official payload space on the Interorbital Launch Manifest. TARDIS will launch with 58 other satellites on an IOS NEPTUNE rocket in 2014.
MOJAVE-10.24.2013---At dawn on October 21, 2013, Interorbital Systems conducted a short-burn flight qualification run of its main rocket engine in a spectacular hot-firing at the Mojave Spaceport. An incandescent 24-foot beam of fire thundered from the engine’s ablative combustion chamber . . .
