Vast, a US-based space company, has proposed a collaboration with the Indian Space Research Organisation (ISRO) for the Bharat Antariksh Station, which India plans to establish by 2035. The proposal includes offering access to Vast's planned Haven-1 space station, scheduled to launch in May 2026, and exploring opportunities for shared capacity and resources.

Vast CEO Max Haot discussed potential collaborations with ISRO officials, suggesting the possibility of hosting Indian scientists and engineers on Haven-1. He also expressed interest in accessing the Bharat Antariksh Station once it is operational. Haven-1, a single-module space station with a mission life of three years, is designed as a precursor to Haven-2, which Vast hopes will succeed the International Space Station (ISS) after its retirement in 2031. The ISS is a collaborative project involving the US, Russia, Canada, Japan, and the European Space Agency. China launched its own space station, Tiangong, in 2021 and has since maintained a human presence in space.

Haot emphasized the potential for collaboration between the US and India, highlighting the current geopolitical landscape where the other two human spaceflight-capable countries (Russia and China) face political constraints in working with the US. He noted that this creates a unique opportunity for the two countries to cooperate in space exploration.

India intends to launch the first module of the Bharat Antariksh Station in 2028 and complete its construction by 2035. Vast is also open to the possibility of using India's Gaganyaan vehicle for transporting customers to Haven-1, provided it offers a competitive, reliable, and safe launch option. The Haven-1 spacecraft, with a 45-cubic-meter volume, is designed to accommodate up to four crew members for missions averaging two weeks. It features four crew quarters, mid-deck lockers for science modules, and a common area with a deployable table and crew interfaces.

In 2023, NASA signed a five-year Space Act Agreement (SAA) with Vast to support the company's development of space station modules.
