Rendezvous Robotics, a company that says it's building spacecraft that assemble themselves in orbit, has raised $20 million, with MaC Venture Capital and Toyota Ventures leading the financing.
The new funding comes as the company prepares for a first-of-its-kind mission in 2028, when seven independent spacecraft tiles will autonomously join to form a single spacecraft, separate and assemble again into a different configuration.
The capital will support development of the company's next-generation spacecraft, flight demonstrations and team expansion.
Most spacecraft are designed around what fits inside a rocket fairing, the company said, a constraint that forces engineers to make tradeoffs in power generation, compute, antenna size and heat dissipation before launch.
Rendezvous said it gets around these limitations by launching its craft as compact, independent modular tiles, that autonomously maneuver, align and connect in orbit. The modular design allows spacecraft to be assembled into larger structures and reconfigured after launch to adapt to new missions.
Rendezvous builds on nearly a decade of research that began with TESSERAE, a modular self-assembly technology invented by Dr. Ariel Ekblaw at MIT and further developed through the Aurelia Institute, which Ekblaw founded. Earlier generations have flown aboard Blue Origin's New Shepard rocket and on two missions to the International Space Station (ISS), providing the foundational proof of the underlying technological concept in microgravity.
"The vision behind TESSERAE was never simply to connect tiles in space. It was to rethink how we build beyond Earth," said Ekblaw, co-founder and board chair of Rendezvous Robotics. "For decades, the way we build spacecraft has been shaped by what we can fit inside a rocket. We're challenging that constraint. What began as an experiment in self-assembly is now becoming a new way to build spacecraft in orbit."
The company is now developing a new generation of larger, independently operating spacecraft tiles, with ground demonstrations underway to validate autonomous movement, alignment and assembly. A planned parabolic flight campaign in November 2026 will further test electromagnetic actuation and mobility in microgravity. These efforts are leading to Rendezvous' low-earth demonstration, scheduled to launch aboard a reserved rideshare no earlier than April 2028. The mission will feature fully autonomous assembly and reconfiguration of independently deployed Rendezvous spacecraft tiles in free space, demonstrating how spacecraft can change their physical structure after launch without external robotic assistance.
"What stood out to us is that autonomy isn't an added feature. It's fundamental to how Rendezvous is designing its spacecraft," said Chris Abshire, partner at Toyota Ventures, in a statement. "The ability for individual modules to maneuver, connect, and eventually reconfigure in orbit could create an entirely new set of options for spacecraft designers and operators. Toyota Ventures sees significant potential in the combination of robotics, modularity and autonomous control."
