Revolutionizing the way humans experience space 

Spaceship Neptune

Developed to be the most accessible, sustainable, and safest spacecraft on or above planet Earth, Spaceship Neptune comprises the SpaceBalloon™, capsule, and reserve descent system, with all components covered by patents. Spaceship Neptune is regulated under the FAA under FAR Part 460 - Human Space Flight Requirements and follows guidelines set forth by NASA and the U.S. Coast Guard.

The SpaceBalloon™

Spaceship Neptune is lifted gently to space by our SpaceBalloon™, which is propelled by renewable hydrogen at the gentle speed of ~12 mph. Based on proven technology, our SpaceBalloon™ is the same type that has flown to space more than a thousand times by NASA and other reputable entities—not to mention by our own team members—including with payloads heavier than our Spaceship Neptune capsule.

The Capsule

Soon to be the largest human spacecraft in operation (excluding the space stations), Spaceship Neptune's spherical capsule is 16 feet (4.9 meters) in diameter, providing a pressurized volume of more than 2,000 cubic feet (60 cubic meters). The capsule interior maximizes both space and comfort and accommodates eight Explorers and a Captain.

The Reserve Descent System

In addition to our primary flight system, Spaceship Neptune is equipped with a backup descent system—four parachutes situated between the capsule and the SpaceBalloon™ that can take over seamlessly and instantaneously in the event of a contingency, ensuring a safe landing. These kinds of parachutes have been used by spacefaring agencies over decades without incident.

The Space Lounge 

Every seat is the best seat in the house inside our roomy cabin thanks to panoramic views through the largest windows ever flown to space.

The Seats

Every seat is engineered for safety and comfort. Seats are oriented within the cabin to maximize views of the stars above and Earth below. Ergonomically designed, these seats merge the best of aerospace innovation with the luxury of first-class travel.

The Space Spa

Our one-of-a-kind restroom provides a spa-like sanctuary during the six-hour spaceflight. The lavatory will not only surpass the experience you would find in a first-class airplane cabin, but also will serve as a solo oasis. Because the capsule is pressurized, there is no need for a vacuum toilet like on other spacecrafts. Having a proper and beautifully designed lavatory on board contributes hugely to the uniqueness of the experience we are offering.

Expert Engineering

Every major element of its spaceship is covered by a patent. This includes the SpaceBalloon™, the method of launching a SpaceBalloon™ from a ship, the reserve descent system, the heat-rejecting radiator technology, the capsule structure with vertical windows, and the Splashcone, which attenuates the capsule to provide a gentle ocean landing and then becomes a sea anchor to stabilize the capsule.

Testing Innovation

Designing Spaceship Neptune is an engineering feat, requiring a modern suite of tools to maximize comfort, safety, and sustainability from design testing to production. We collaborate with Siemens to develop a comprehensive digital twin to visualize and test the capsule and its systems in an unprecedented way and accelerate processes.

Capsule Build

Spaceship Neptune will be the largest human spacecraft in operations (excluding the space stations), and represents a significant milestone in U.S. entrepreneurship and the first commercial spacecraft designed, developed, and manufactured without the backing of a billionaire or significant government funding. Our capsule teams bring decades of industry expertise from the likes of NASA, SpaceX, and Virgin Galactic.

In-House Production and Facilities

Uniquely, Space Perspective is vertically integrated with in-house capsule design, manufacturing, testing, and operational functions. This includes a carbon composite manufacturing facility with state-of-the-art process control, a material testing laboratory, and a capsule integration hangar. The flight electrical and power systems, software, mission control, and the environmental control and life support systems (ECLSS) are also designed and built in-house, as are the company's SpaceBalloon™, which are manufactured in its 700-foot-long Seely SpaceBalloon™ Factory, named after late chemical engineer and balloon science pioneer Loren G. Seely, whom the company's head of balloon development and manufacturing studied under.

"We are on the cusp of a staggering shift – not only in the way we humans experience space, but also what we conjure in our minds when we think of the spaceship that gets us there. We are redefining the category and paving the way for accessible space travel for years to come."
