Sidesat

Sidesat refers to a type of satellite that is launched into orbit and then maneuvers to position itself alongside another satellite. This positioning is typically done for a variety of purposes, including inspection, servicing, or even de-orbiting. The term "sidesat" is a portmanteau of "side" and "satellite."

The primary function of a sidesat is to get close enough to a target satellite to interact with it. This interaction can range from taking high-resolution images to physically docking with the target. For inspection, a sidesat can provide detailed visual data of a satellite's condition, which is crucial for assessing its health or identifying potential damage. In the realm of satellite servicing, sidesats can perform tasks such as refueling, repairing components, or upgrading equipment, thereby extending the operational life of the target satellite.

Another significant application of sidesats is in space debris mitigation. A sidesat can be designed to capture or tow defunct satellites out of their orbits, preventing them from becoming a collision hazard for active spacecraft. This capability is becoming increasingly important as the amount of space debris in orbit continues to grow. The development of sidesat technology represents a significant advancement in on-orbit servicing and space sustainability efforts.
