trajectory
path of a moving object
world line
unique path of an object as it travels through 4-dimensional spacetime
cycler
spacecraft trajectory that passes by two or more celestial bodies periodically
flyway
aerial route taken by migrating birds
Mars cycler
spacecraft trajectory that encounters Earth and Mars regularly
free-return trajectory
trajectory of a spacecraft to a secondary body which allows the vehicle to return to the primary body without propulsion
limit cycle
closed trajectory in a 2d phase space of a dynamical system such that that another trajectory spirals into it as time approaches ±∞
hyperbolic trajectory
trajectory of any object around a central body with more than enough speed to escape the central object's gravitational pull
orbit insertion
entry into a stable orbit around an astronomical object
circumlunar trajectory
type of free-return trajectory
orthogonal trajectory
Definition in differential equations
trans-lunar injection
propulsive maneuver used to arrive at the Moon
trajectory
In fluid mechanics, the path of an object in a flow
contrail
long, thin artificial clouds that sometimes form behind aircraft
EEO
Type of orbit
path of least resistance
physical or metaphorical pathway that provides the least resistance to forward motion
line-of-sight
straight line between a missile and its target
route
planned path for a receiver in American or Canadian football
Trans-Earth injection
propulsive maneuver used to arrive at Earth
orbit
curved path of an object around a point
line-of-sight propagation
characteristic of electromagnetic radiation or acoustic wave propagation which means waves which travel in a direct path from the source to the receiver
course
direction or route along which an object travels
parabolic trajectory
unbound Kepler orbit with the eccentricity equal to 1
Representative Concentration Pathways
concentration of emissions scenarios
