A series of burns to set two spacecraft on orbits of the same shape, size, and orientation but with different periods for a rendezvous.

A retrograde burn (opposite to the direction of flight) to reduce a spacecraft's velocity, causing it to re-enter the Earth's atmosphere.

A maneuver using the relative movement and gravity of a planet or other celestial body to alter the path and speed of a spacecraft.

Used to adjust the timing of a spacecraft's orbit to synchronize with another object in space.

Small maneuvers performed periodically to maintain a spacecraft's intended orbit against perturbations.

When a spacecraft performs a flyby of a celestial body while simultaneously firing its engines to gain additional energy.

A two-impulse maneuver used to transfer between two orbits with common focus; most commonly between a lower circular orbit and a higher circular orbit.

A three-impulse maneuver involving two elliptical orbits to transfer a spacecraft from one orbit to a significantly higher one.

A maneuver used to change the tilt of an orbit plane relative to the central body's equatorial plane.

A spacecraft performs a burn to counteract orbital decay and raise its orbit, often used for space stations like the ISS.

A maneuver to move a spacecraft from a parking orbit to a transfer orbit, heading towards its final trajectory.

Orbital maneuver to bring two spacecraft together in space, involving synchronization of their orbits.

Launching a spacecraft directly into its desired orbital path without first entering a lower, temporary orbit, and without using a transfer orbit.

A change in a spacecraft's orbital plane, typically performed at a node where the initial and desired orbital planes intersect.
