Vast

Overview

Vast is a commercial space station developer focused on creating human habitats in low Earth orbit and eventually artificial gravity stations. Founded by cryptocurrency entrepreneur Jed McCaleb and led by CEO Max Haot, the company pursues an incremental, hardware-rich development approach to rapidly build orbital infrastructure. Vast's architecture centers on modular station designs that can be expanded over time.

The company's initial product, Haven-1, represents a single-module commercial space station planned for launch in 2026. Following successful demonstration of Haven Demo in late 2025—making Vast the only operational commercial space station company to fly hardware—the company is advancing toward its first crewed station. Vast's strategy includes early ISS integration through private astronaut missions and NASA partnerships for ground testing.

In March 2026, Vast closed a $500 million funding package ($300 million in Series A equity plus $200 million in debt financing) with investment from Nikon and other strategic partners, bringing total funding raised to over $1 billion, reflecting confidence in the commercial space station market as the International Space Station approaches retirement. The company has expanded beyond station development into satellite bus manufacturing, announcing a line of high-power satellite platforms in May 2026. Vast's long-term vision includes multi-module Haven Station configurations and eventually artificial gravity habitats for extended human presence in orbit.

Haven-1

Haven-1 is Vast's first single-module commercial space station designed to host up to four crew members. The station features a cylindrical pressure vessel with life support, power, and docking capabilities. Primary structure completion occurred in July 2025, ahead of the original target May 2026 launch date, which has since slipped to NET Q1 2027. Haven-1 will support private astronaut missions, research activities, and serve as a pathfinder for Vast's multi-module Haven Station architecture. The station underwent fit-check testing in October 2025 and environmental testing at NASA facilities in 2025.

Haven Demo

Haven Demo was a technology demonstration spacecraft that deployed from the Bandwagon-4 rideshare mission in November 2025. The mission achieved full success, validating key systems and technologies for Haven-1. The spacecraft was intentionally deorbited in February 2026 after completing its test objectives, making Vast the first commercial space station company to successfully operate hardware on-orbit.

Haven Station

Haven Station represents Vast's multi-module expansion concept, building on Haven-1 with additional pressurized modules to increase crew capacity and research capabilities. The architecture allows for incremental growth and configuration flexibility. The Exploration Company has been contracted to provide cargo resupply missions to Haven Station.

High-Power Satellite Buses

Announced in May 2026, Vast is offering a line of high-power satellite buses leveraging the company's spacecraft design and manufacturing capabilities developed for space station hardware. Specifications and performance parameters have not been publicly disclosed.
