Roadmap

Vast is developing artificial gravity space stations to expand humanity across the solar system.

Our Mission: Live in Space

At Vast, our mission is to contribute to a future where billions of people are living and thriving in space — a future in which the human population and our resources expand far beyond our current imagination.

However, today’s astronauts must limit their visits to space to reduce the toll on their bodies. By building artificial gravity habitats, we aim to create a more optimal environment for long-term stays in space.

Artificial gravity is not science fiction. The resulting centrifugal force of a large spinning structure in space provides a pull that mimics the gravitational environment human bodies are accustomed to, thus reducing the detrimental physiological effects that extended stays in zero gravity cause.

Funding & Customers

Vast is exclusively funded today by our Founder, Jed McCaleb. This funding is expected to take us through our Haven-1 and Crew Mission-1.

We are building Vast as a long-term profitable company and aim to service NASA and other US Government organizations, international space agencies, private individuals engaged in research and philanthropy, and institutions and companies needing platforms for in-space research and manufacturing.

Making it a Reality

road to artificial gravity space stations

2040s

proliferated station fleet

Location: Solar system
Environment: Artificial & zero gravity
Total Crew: Hundreds

Vast will be operating dozens of artificial gravity and zero gravity space stations across our solar system, optimized for human physiology and psychology, as well as off-planet business. These will enable every endeavor imaginable as humanity expands across the solar system.

2030s

100-Meter Spinning Stick Stations

location: Low-Earth orbit and beyond
Environment: Artificial gravity
Total Crew: 40 each

Vast will be operating 100-meter-long spinning stick space stations that provide various gravitational environments including Earth, Venus, Mars, Moon, and near-zero gravities. The stations will be comprised of seven individually launched Starship-class modules. Our first spinning stick station will help us understand how humans cope with gravity at varying levels in order to inform optimal artificial gravity levels for extended-duration space travel.

Vast will also operate co-orbital free-flying zero gravity modules for large-scale manufacturing, research, and tourism, while maintaining rapid access to the gravitational environments of the spinning stations. 

2028

Starship-Class Module

location: Low-Earth orbit
environment: Artificial & zero gravity
Total Crew: 4

Vast will be operating its first Starship-class space station module. At seven meters in diameter, the unprecedented large volume will provide unparalleled potential for research, tourism, and more.

2025

Haven-1: Falcon 9-Class module

location: Low-Earth orbit
environment: Artificial & zero gravity
Total Crew: 4

Vast will be operating its first space station, Haven-1. Haven-1 is a single-module space station that will provide microgravity and Lunar artificial gravity environments. It will accommodate a crew of 4 via a visiting SpaceX Dragon spacecraft.

2024

Haven Demo

location: Low-Earth orbit
environment: Zero gravity
Total Crew: N/A

Haven Demo is a strategic stepping stone that allows Vast to test the same qualified hardware and software that will support crew on Haven-1.  It affords the team with opportunities to develop robust spaceflight and team operations.

  • Train our team to design, produce, integrate, launch, and operate in space.
  • Develop and test in orbit our safety-critical, human-rated space station avionics hardware and software, which will evolve from Orbiter to Haven-1.
  • Develop systems and expertise for in-space maneuvers and approaches which are critical to space station assembly and re-supply.
  • Test Haven-1 subsystems on orbit, including life support (ECLSS), avionics, software, communication, materials, and sensors.

The Earth has a mass of 6 x 1024 kg. The solar system, other than the Sun, has a mass of 2.78 x 1027 kg. This gives 464 Earth masses in the solar system excluding the Sun. But humans are using at most 2% of the Earth’s mass. This means there are 23,200 times the amount of mass used by humans out there in the solar system. Or roughly enough resources for 232 trillion humans. There is an even greater multiple of the current human energy requirements emitted by the Sun, so the solar system is mass constrained not energy constrained.
