Vast Unveils Astronaut Flight Suit and Tests Timepiece for Haven-1 Space Station

On April 22, 2026, Vast revealed its novel Astronaut Flight Suit designed for crew members aboard the upcoming Haven-1 space station, marking a shift from the casual attire commonly used on the International Space Station to a more purpose-built garment for orbital living and work. The suit, introduced alongside testing of a custom Swiss timepiece, reflects the company’s focus on human-centered design for long-duration missions in low Earth orbit.

A Purpose-Built Suit for Orbital Life

The Vast Astronaut Flight Suit is a two-piece outfit consisting of a jacket and trousers, engineered for use inside pressurized space stations. Unlike the standard polo shirts and cargo pants often worn by astronauts on the ISS, Vast’s suit integrates functional elements tailored to microgravity environments. It features multiple zippers, pockets, and hook-and-loop fasteners strategically placed to allow secure attachment of tools, personal items, and equipment — critical in a setting where everything must be fastened to prevent floating.

According to Vast’s lead astronaut and former NASA mission specialist Drew Feustel, who has logged over 225 days in space, the design evolved from direct input by experienced astronauts. “Over the last two decades on the International Space Station, astronauts have moved away from wearing flight suits every day,” Feustel stated. “The environment has become safer and more like how we work on Earth.” The suit aims to honor the heritage of aviation flight suits while adapting to modern operational needs aboard commercial stations like Haven-1.

Testing a Space-Ready Timepiece

In parallel with the suit unveiling, Vast announced it had tested and certified a custom-made Swiss wristwatch for use aboard Haven-1. The timepiece underwent evaluation to ensure it meets the rigorous demands of spaceflight, including resistance to vibration, magnetic fields, and temperature fluctuations. While specific technical details of the watch were not disclosed, its certification signifies Vast’s effort to provide astronauts with reliable, mission-appropriate personal gear.

Feustel noted the historical significance of standardized flight attire, referencing how early NASA astronauts in the Mercury program had to scramble for uniform clothing due to a lack of issued gear. The iconic image of the Mercury Seven in mismatched garments before an F-106 jet ultimately led to the adoption of the now-familiar blue NASA flight suit. Vast’s approach seeks to blend that legacy with contemporary functionality.

Designed for Haven-1 and Beyond

The Astronaut Flight Suit is intended for use during missions to Haven-1, which Vast describes as the world’s first commercial space station. Crews will wear the suit during training, public events, and onboard operations. It will as well be used during Vast’s contracted private astronaut mission to the International Space Station, conducted in partnership with NASA.

Vast positions the suit as part of a broader effort to develop sustainable infrastructure for long-term human presence in orbit. Alongside the garment, the company has been advancing other Haven-1 systems, including a large-scale docking adapter designed to improve compatibility between visiting spacecraft and station modules.

Advancing Human-Centered Design in Space

By prioritizing mobility, comfort, and task-specific utility, Vast’s flight suit represents a step toward treating spacecraft interiors more like terrestrial workspaces — without sacrificing the symbolic role of professional attire in exploration. The company emphasizes that the suit was developed “by astronauts, for astronauts,” incorporating real-world feedback from those who have lived and worked in microgravity.

As Vast prepares for the launch of Haven-1 and subsequent missions, the Astronaut Flight Suit and certified timepiece illustrate how commercial space operators are refining everyday aspects of life beyond Earth to support safety, efficiency, and crew well-being.
