It has been already almost ten years since the last flight of the Space Shuttle. From that moment humanity has lost the capability of repairing/updating satellites during their lifetime, as it was done with the Hubble Space Telescope. Also, notorious are the challenges that engineers had to solve to make the James Webb Telescope accommodate into the Ariane 5 Rocket Fairing.

These are just one of the things that the HARSA formation can accomplish "easily". It is a paradigm shift, the usual docking of big space assemblies which required a continuous presence of humans in space (like for the assembling of the ISS) or the use of huge robotic arms is a thing of the past.

In the near future, space stations, huge telescopes, etc. could be assembled completely autonomously, the only requirements for the spacecrafts to assembly is to present an appropriate "handle" that the HARSA CubeSats, coordinated by the HARSA mothership, will be able to grab autonomously.

The HARSA mothership realizes the communication with GS, providing information about how the work in the building site is proceeding. It also serves as a cross-link to let the swarm inter-communicate.

The HARSA CubeSat is equipped with a very short Robotic arm with 3 DOF, and a stereoscopic camera, the CubeSat movement is coordinated by the mothership and rough position of the component to grab is thus known. The camera as the aim of facilitating the CubeSat approach, it's a stereoscopic camera, the on-board computer equipped with an apposite artificial intelligence, will identify the pattern (similar to a QR code) which surrounds the handle to grab.

Then using the electric propulsion unit of electrospray (with which every CubeSat is equipped) the CubeSat is able to apply a small but continuous force to the structures to manipulate. Time is not a constraint for this kind of propulsion units, due to their very high specific impulse the fuel will finish only after many months of continuous work.

Using this procedure big structure can be put together.

The CubeSats then are released by an apposite spring driven mechanism allowing the undock and letting it depart towards the next destination.

We had a chance to lay out also a very preliminary business plan: the baseline is to provide a comprehensive service to the clients: the hypothetical "space hotel" provider will not care anymore about docking and designing the system to dock since the service is external. This way, the clients save in terms of weight (the docking system is physically external, except for the standardized docking port itself) complexity and development costs, since they don't have to design all the complex assembly phase.

The business offer includes both the CubeSats ad mothership, but also the integration of the 

simple, lightweight standardized handles for the in-space interface of the CubeSats.
