Interorbital marks major milestone with rocket engine firing

On a calm clear High Desert October evening, Interorbital Systems’ NEPTUNE rocket series’ main engine roared to life in its first hot-firing test in Mojave, Calif.

The engine, the IOS GPRE 7.5KNTA (General Purpose Rocket Engine; 7,500 pound thrust; Nitric Acid; Turpentine; Ablative cooling), blasted a 22-foot plume of fire across Interorbital’s Mojave Spaceport test area, scorching the sand an additional 50 feet beyond the plume end.

The all-composite chambered 7,500-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) – powered by seven of the 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.

NASA seeks proposals for extreme environment solar arrays

NASA’s space technology program is seeking proposals to develop solar array systems for space power in high radiation and low solar energy environments. In the near future, NASA will need solar cells and arrays for multiple applications in robotic and human space exploration missions. Because these systems were traditionally developed for operation near Earth, there...
