Spacecraft could one day change their shape after reaching orbit, allowing operators to add capabilities without launching an entirely new vehicle. Rendezvous Robotics has raised $20 million to develop that technology, with its first orbital demonstration planned for 2028.

The startup intends to launch seven independent spacecraft tiles that will join together in space. They will then separate and assemble into a different configuration, testing whether autonomous spacecraft can build and reshape larger structures without external robotic assistance.

MaC Venture Capital and Toyota Ventures led the oversubscribed seed round. Rendezvous will use the funding to advance its spacecraft designs and prepare for flight demonstrations.

Rocket fairings dictate the dimensions of conventional spacecraft before they leave Earth. Engineers must fit every component within that envelope, limiting the size of equipment such as antennas and power systems.

Rendezvous wants to move some of that construction work into orbit. Its spacecraft launch as individual tiles that maneuver independently before connecting with one another. The resulting structure can exceed the dimensions of any single module.

Reconfiguration presents a further engineering challenge. The seven tiles must coordinate their movements and establish connections before separating and forming a new arrangement. The planned mission will test whether they can complete those operations autonomously in low Earth orbit.

CEO Joe Landon believes the approach could eventually support spacecraft with megawatt-scale power generation. He also sees potential for much larger communications and sensing apertures. Those capabilities could support missions that face significant constraints under conventional spacecraft designs.

The technology originated with TESSERAE, a modular self-assembly concept developed by Ariel Ekblaw at MIT.
