Destinations

Interorbital Systems is following a step-by-step program to develop the hardware necessary to carry out an affordable systematic conquest of the Solar System. Its unique two-stage sea-based mobile modular launch vehicles, the NEPTUNE Series, is the key component required to make this goal achievable. Current mission destinations include Low Earth Orbit, the Moon, Mars, and Venus.

NEPTUNE Modular Launch Vehicles: How we get there!

Interorbital's NEPTUNE series modular launch vehicles are built from one or more NEPTUNE Building Blocks connected in parallel or stacked in tandem. All three of the NEPTUNE Series modular rockets are two-stage orbital launchers. Once a space mission's requirements are specified, the launch vehicle can be custom-built for the mission by varying the number of NEPTUNE Building Blocks (2, 9, or 36).


More about the NEPTUNE

Since the NEPTUNE Building Blocks have fewer systems than standard launch vehicles, they can be rapidly built on an an automated assembly line. Since the NEPTUNE Building Blocks are all identical, the modular rockets can be assembled with efficient, standardized assembly techniques.

Low-Earth Orbit

Interorbital's smallest orbital launch vehicle, the NEPTUNE 2 Two Stage (N2TS), is capable of lifting 30.0 kg (66.2-lbs) into a circular polar Low-Earth-Orbit. Two other NEPTUNE variants, the N9TS and the N36TS will be capable of launching between 1,250-kg (2,756.25-lbs) and 3,200-kg (7,056.00-lbs) payloads to LEO. The flexibility of the NEPTUNE rocket-series allows IOS to quickly customize launch vehicles according to customer need.

With its low-cost satellite kit-and-launch packages, IOS also offers the world's most cost-effective space solutions for small-sat customers. Purchase of an IOS satellite kit and launch, complete with the hardware necessary to build a satellite, also places the customer on the IOS launch manifest for the next available flight.

To the Moon

Interorbital Systems is completing the development of its LunarStation to provide low-cost commercial access to the Lunar surface. A solid rocket motor slows the LunarStation before it is jettisoned for landing on the Moon. It bounces to a stop on the Lunar surface with its airbag deceleration system, deflates its airbags, opens its petals, and activates its payload. Features include solar power, communications, and ports for one or more customer payloads. The LunarStation can carry a 40.0-kg (88.2-lbs) payload to the Lunar Surface at the lowest price for a Lunar mission on the planet.


More about the LunarStation

A lunar sample return mission will be the next phase of the IOS Lunar mission program. The sample-return mission’s primary hardware component is the Robotic Interplanetary Prospector Excavator and Retriever, or the RIPPER. RIPPER is an autonomous system, designed to soft-land on the moon or any other body in the Solar System, select surface samples, and then excavate and retrieve them for return to Earth.

In the future, IOS plans to establish a lunar base, with its own regular shuttles to and from the Earth for scientists, industrialists, and tourists alike. IOS manned Lunar space technology will begin with the development of its two-man LEO capsule spacecraft.

Exploring the Solar System

Long-term plans see IOS rockets launched on trajectories throughout the solar system. From establishing settlements on the Moon, Mars, and Venus to sending probes to the moons of Jupiter and Saturn, the modularity of the NEPTUNE series rockets allow Interorbital to change mission profile and destination without the exhaustive development cycles and the extreme costs that characterize the classic aerospace industry.

As IOS production ramps up, expect to see the NEPTUNE Rocket sending payloads to exotic destinations near and far in the Solar System, and beyond. In particular, IOS will provide launch solutions to make human space travel more widely available. Whether exploring remote destinations with scientific probes or ferrying tourists and scientists to the company's research station at the Moon's Southpole, IOS will be a key player in the expansion of humanity into the Solar System.
