Space Walker

Space Walker is a Japanese startup originating from Tokyo University of Science, focused on developing reusable suborbital spaceplanes. The company’s core business centers around providing sustainable space transportation solutions, aiming to democratize access to space – envisioning a future where space travel is as commonplace as air travel. Space Walker is currently developing a vehicle, branded “ECO ROCKET®,” designed for both manned spaceflight and satellite launch capabilities.

A key technological differentiator for Space Walker is its focus on lightweight composite materials, specifically in the development of propellant tanks utilizing patented technology. They are also advancing autonomous navigation and guidance control systems to enable fully self-directed, round-trip flights. This emphasis on reusability directly addresses a major challenge in the space industry – reducing space debris and the environmental impact of disposable rockets.

Space Walker’s development plan is structured around a four-stage milestone process, with a clear commitment to open innovation through collaboration between academia, industry, and government. The “ECO ROCKET®” is designed to utilize carbon-neutral liquid biomethane fuel, further reinforcing the company’s commitment to sustainable space access.

While specific missions or customers are not currently detailed, Space Walker positions itself as a disruptive force in the launch market, advocating for reusable launch systems and environmentally responsible space transportation. The company aims to establish a new economic sphere in space, contributing to a more sustainable and prosperous future for humanity.
