Rendezvous Robotics is a space infrastructure company building modular spacecraft that assemble themselves in orbit. Its TESSERAE technology uses flat-packed hexagonal tiles with electromagnetic docking interfaces that launch stacked inside a rocket fairing and then autonomously self-assemble and reconfigure in microgravity, without astronauts, robotic arms, or propulsion. The approach is intended to remove the fairing-size ceiling on satellite design and allow orbital structures to be upgraded rather than replaced. The technology originated in MIT research by co-founder Ariel Ekblaw and has flown three space missions, with a further ISS demonstration in mid-2026 and a free-flight autonomous assembly mission planned for late 2026.
