Science drivers
Black holes, relativistic jets, star and planet formation, evolved stars, and other compact structures requiring extreme angular resolution.
A long-term vision for space interferometry
Building the foundations for an astronomical array in space.
The Space Array initiative explores how distributed spacecraft, precision formation flying, high-frequency receivers, and advanced correlation techniques could enable transformational angular resolution from space.
Mission concepts
From focused demonstrators to ambitious multi-spacecraft observatories, the initiative studies credible paths toward a future space array.
Technology roadmap
Key enabling technologies include inter-satellite metrology, time and frequency transfer, data transport, correlation, orbit determination, and imaging.
Why now?
Recent progress in small satellites, precision navigation, optical links, high-performance computing, and millimetre/sub-millimetre instrumentation makes it timely to revisit space interferometry as a coordinated, long-term programme.
High-frequency phase stable imaging will breakthrough the current understanding of the mystery of astrophysical sources.
The goal of this website is to provide a public entry point for the initiative: the scientific motivation, candidate mission concepts, technical challenges, workshops, references, and ways to get involved.
