Interorbital Systems (IOS) is an American company based in Mojave, California, that specializes in the manufacturing of rockets and satellites. [2] It was established in 1996 by Roderick and Randa Milliron. As of October 2023, the company is in development stage for three orbital launch vehicles: NEPTUNE, TRITON, and TRITON HEAVY. [1]
Interorbital Systems has participated in the development of a launch vehicle for the Google Lunar X Prize Team Synergy Moon [3] and has provided suborbital commercial launch services. For Orbital launch they have used ISRO and Jaxa. [4] Additionally, the company participated as a competitor in the Ansari X Prize [5] and America's Space Prize competitions. [6]
The NEPTUNE rocket, a two-stage vehicle developed by Interorbital Systems, uses high-performance liquid oxygen and densified propane propellants. [7] [1] The first stage is equipped with four stationary throttleable ablativelycooled liquid rocket engines, each capable of generating 4,500 pounds of thrust. [8] Throttling of these engines allows for precise control of pitch, yaw, and roll during flight.
The second stage of the NEPTUNE rocket is powered by a single stationary ablativelycooled 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 are provided by cold-gas thrusters.
The NEPTUNE liquid rocket engines of Interorbital Systems are fed propellants through a proprietary pressurant system. As a result, the weight of the propellant tank/pressurant system is equivalent to a traditional propellant tank/pressurant system/pump-fed system.
By removing the propellant pump and the associated heavy electric or gas-generator pump-drive system, Interorbital Systems has significantly reduced both the overall rocket development cost and the manufacturing time. This streamlined approach to the propulsion system has led to cost savings and improved efficiency in the manufacturing process. [9]
All Interorbital Systems (IOS) rockets are launched from an ocean barge equipped with motion compensation technology. Initially, IOS plans to conduct orbital flights from the Pacific Ocean southwest of Los Angeles.[ citation needed ]
In 2006, IOS held an active launch license from the Office of Commercial Space Transportation for Tachyon, [10] a sounding rocket designed for suborbital flights reaching an apogee of 120 miles.
Solaris was a suborbital rocket design developed by IOS in the early 2000s. The intention behind the Solaris project was to compete for the Ansari X Prize. However, the rocket was not completed in time, and it was surpassed by Scaled Composites' SpaceShipOne, which successfully claimed the prize. [6]
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.[ citation needed ]
The Common Propulsion Module Test Vehicle (CPM TV) completed its inaugural test flight on March 29, 2014, [11] achieving a maximum altitude of 10,000 feet. The payloads on board included two CubeSats, a payload from Synergy Moon, and a music CD titled "ENCLOSURE" by John Frusciante, former guitarist of the Red Hot Chili Peppers. [12] The CPM TV will be reused for future test flights, and all payloads were successfully recovered without damage. [11]
The CubeSat Personal Satellite Kit is available in two configurations: a standard 1 kg (2.2 lb) version and a non-standard 1.33 kg (2.93 lb) version. 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 personal purposes.[ citation needed ]
The TubeSat Personal Satellite Kit offers an alternative to CubeSats. These kits are constructed entirely from printed circuit boards.[ citation needed ]
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.[ citation needed ] The company has a significant number of launches planned for both types of satellites.

Interorbital Systems became a member and launch provider for Team Synergy Moon in the Google Lunar X Prize competition in June 2016. [14] [3] The team used a modified version of the NEPTUNE rocket consisting of 36 modules to transport their lunar rover to the surface of the Moon. [15]
Spaceflight is an application of astronautics to fly objects, usually spacecraft, into or through outer space, either with or without humans on board. Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in orbit around Earth, but also includes space probes for flights beyond Earth orbit. Such spaceflight operate either by telerobotic or autonomous control. The more complex human spaceflight has been pursued soon after the first orbital satellites and has reached the Moon and permanent human presence in space around Earth, particularly with the use of space stations. Human spaceflight programs include the Soyuz, Shenzhou, the past Apollo Moon landing and the Space Shuttle programs. Other current spaceflight are conducted to the International Space Station and to China's Tiangong Space Station.
The Polar Satellite Launch Vehicle (PSLV) is an expendable medium-lift launch vehicle designed and operated by the Indian Space Research Organisation (ISRO). It was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into Sun-synchronous orbits, a service that was, until the advent of the PSLV in 1993, only commercially available from Russia. PSLV can also launch small size satellites into Geostationary Transfer Orbit (GTO).
Armadillo Aerospace was an aerospace startup company based in Mesquite, Texas. Its initial goal was to build a crewed suborbital spacecraft capable of space tourism, and it had also stated long-term ambitions of orbital spaceflight. The company was founded by John Carmack, co-founder and former chief technical officer of id Software.
A spaceport or cosmodrome is a site for launching or receiving spacecraft, by analogy to a seaport for ships or an airport for aircraft. The word spaceport, and even more so cosmodrome, has traditionally been used for sites capable of launching spacecraft into orbit around Earth or on interplanetary trajectories. However, rocket launch sites for purely sub-orbital flights are sometimes called spaceports, as in recent years new and proposed sites for suborbital human flights have been frequently referred to or named "spaceports". Space stations and proposed future bases on the Moon are sometimes called spaceports, in particular if intended as a base for further journeys.
The Canadian Arrow was a privately funded, early-2000s rocket and space tourism project concept founded by London, Ontario, Canada entrepreneurs Geoff Sheerin, Dan McKibbon and Chris Corke. The project's objective was to take the first civilians into space, on a vertical sub-orbital spaceflight reaching an altitude of 112 km.
The pressure-fed engine is a class of rocket engine designs. A separate gas supply, usually helium, pressurizes the propellant tanks to force fuel and oxidizer to the combustion chamber. To maintain adequate flow, the tank pressures must exceed the combustion chamber pressure.
Micro-Space was an aerospace corporation based in Denver, Colorado, founded in February 1977 by Richard P. Speck under the name Spectron Instrument Corporation. The corporation changed its name to "Micro-Space, Inc." in 1998. It was dissolved in 2011, following the death of the founder.
Masten Space Systems was an aerospace manufacturer startup company in Mojave, California that was developing a line of vertical takeoff, vertical landing (VTVL) rockets, initially for uncrewed research sub-orbital spaceflights and eventually intended to support robotic orbital spaceflight launches.
The Google Lunar X Prize (GLXP) was a 2007–2018 inducement prize space competition organized by the X Prize Foundation, and sponsored by Google. The challenge called for privately funded teams to be the first to land a lunar rover on the Moon, travel 500 meters, and transmit back to Earth high-definition video and images.
Moon Express is an American privately held company formed in 2010 by a group of Silicon Valley and space entrepreneurs.
