Today at IAC 2024, Vast introduced Haven-2, our proposed successor to the International Space Station (ISS). The first module will be fully operational by 2028, ensuring an overlap of operational space stations before the ISS retires in 2030. This near-term timeline is made possible by leveraging Vast’s significant private investment in the design, build, launch, and operation of Haven-1. When completed in 2032, Haven-2 is designed to surpass the ISS in volume, research facilities, and cost efficiency.
The first Haven-2 Module will be 5m longer than Haven-1, offering nearly twice the livable volume of its predecessor while utilizing all the same proven systems. Following the deployment of the first Haven-2 module, Vast plans to build and launch three additional modules over a two-year period. These modules will adhere to the same efficient and cost-effective design template, further expanding the station’s usable volume, enhancing available facilities, and efficiently delivering additional critical life support systems and consumables.
With each successive Haven-2 module delivery, Vast will introduce more advanced and efficient life support technologies. Each subsequent module will feature expanded payload facilities while maintaining the same fundamental module design and heritage.

Key features of the completed station include an unprecedented 3.8m diameter cupola window, external payload hosting capabilities, a robotic arm, visiting vehicle berthing capabilities, external payload airlock, and an extravehicular activity (EVA) airlock to support customers’ needs. Each module will also feature two Haven-1-like 1.1m dome windows, totaling 16 windows by 2032.
