In orbital mechanics, low-thrust relative transfer is an orbital maneuver in which a chaser spacecraft covers a specific relative distance relative to...

astronautics, the Hohmann transfer orbit (/ˈhoʊmən/) is an orbital maneuver used to transfer a spacecraft between two orbits of different altitudes around...

orbital lifetime of the spent booster so as to curtail space junk. If using low-thrust engines such as electrical propulsion to get from the transfer...

intended orbital changes using impulsive maneuvers that greatly reduces the complexity of finding the correct orbital transitions. Applying a low thrust over...

low thrust. For the case of orbital transfer between non-coplanar orbits, the change-of-plane thrust must be made at the point where the orbital planes...

}{2a}}\end{aligned}}} where v {\displaystyle v} is the relative orbital speed; r {\displaystyle r} is the orbital distance between the bodies; μ = G ( m 1 + m 2...

propellant at low potential energy/high speed multiplies the effect of a burn. Thus for example the delta-v for a Hohmann transfer from Earth's orbital radius...

astrodynamics, orbital station-keeping is keeping a spacecraft at a fixed distance from another spacecraft or celestial body. It requires a series of orbital maneuvers...

acceleration to reach orbital speed. Higher energy orbits like geostationary orbit are often reached via elliptical transfer orbits. One type of orbit insertion is...

notable that large thrust can reduce gravity drag. Delta-v is also required to keep satellites in orbit and is expended in propulsive orbital stationkeeping...

In orbital mechanics a near-rectilinear halo orbit (NRHO) is a halo orbit that passes close to the smaller of two bodies and has nearly stable behavior...

The familiar study of jet aircraft treats jet thrust with a "black box" description which only looks at what goes into the jet engine, air and fuel, and...

a spacecraft to burn its fuel is at the lowest possible orbital periapsis, when its orbital velocity (and so, its kinetic energy) is greatest. In some...

excessive propellant use. An orbital maneuvering system may be needed to maintain or change orbits. Non-rocket orbital propulsion methods include solar...

a low Earth orbit of 200 km). The required additional change in speed, however, is far less because the spacecraft already has a significant orbital speed...

The MOM probe spent about a month in Earth orbit, where it made a series of seven apogee-raising orbital manœuvres before trans-Mars injection on 30...

angular orbital velocity equals its angular rotational velocity so that the Sun's apparent motion ceases; closer to perihelion, Mercury's angular orbital velocity...
