A rendezvous maneuver is a critical orbital operation used in spaceflight to bring two spacecraft into proximity with each other. These maneuvers are essential for missions involving docking, satellite servicing, or the capture of space debris. The process typically involves precise calculations and adjustments to match the orbital paths of the two vehicles, accounting for factors such as velocity, altitude, and inclination.

The most common type of rendezvous maneuver is the Hohmann transfer, which uses two impulsive burns—one to raise the spacecraft’s orbit and another to lower it—bringing it into the target’s path. More complex missions may require multiple smaller adjustments, often guided by onboard navigation systems or ground control. Relative navigation techniques, such as measuring laser ranges or tracking radio signals, help ensure accurate positioning.

Rendezvous maneuvers are fundamental in crewed missions, such as those conducted by the Apollo program or the International Space Station (ISS) resupply and crew rotation flights. Uncrewed missions also rely on them for satellite refueling, repairs, or the deployment of new spacecraft. Challenges include avoiding collisions, managing fuel efficiency, and compensating for orbital perturbations caused by gravitational forces or atmospheric drag.

Safety protocols are strictly enforced, including backup systems and abort procedures, to mitigate risks. Historical examples, such as the Apollo-Soyuz Test Project (1975), demonstrate the success of international collaboration in executing rendezvous operations. Advances in automation and AI continue to improve the precision and reliability of these maneuvers, reducing human intervention while increasing mission success rates.
