The NEPTUNE rocket, a two-stage vehicle design from
Interorbital Systems, would use high-performance liquid oxygen and densified propane propellants. The first stage would be equipped with four stationary throttleable ablatively cooled liquid rocket engines, each capable of generating 4,500 pounds of

These kits are constructed using an aluminum frame and are designed for conducting simple experiments, as well as for receiving and transmitting radio signals. They may also be used for

By removing the propellant pump and the associated heavy electric or gas-generator pump-drive system, Interorbital
Systems proposes to significantly reduce both the overall rocket development cost and the manufacturing time. This streamlined approach to the propulsion system is touted as leading to
150:
The second stage of the NEPTUNE rocket is proposed to be powered by a single stationary ablatively cooled liquid rocket engine that generates 3,000 pounds of thrust. During the second stage engine burn and while in orbit, pitch, yaw, and roll control would be provided by cold-gas thrusters.
159:
The NEPTUNE liquid rocket engines of
Interorbital Systems would be fed propellants through a proprietary pressurant system. As a result, the weight of the propellant tank/pressurant system would be equivalent to a traditional propellant tank/pressurant system/pump-fed system.
271:
According to their claims, the kits will be launched into self-decaying orbits at an altitude of 310 km (192 mi), eventually burning up in the Earth's atmosphere. The company has a significant number of launches planned for both types of satellites.

The main engine of the Common
Propulsion Module (CPM) underwent its first successful static engine firing on October 28, 2012. This composite chambered engine generated 7,500 pounds of thrust and used nitric acid and turpentine propellants.
