For polar orbits and Molniya orbits this does not apply.

For a Molniya orbit, set the semi-major axis to 26562 km and eccentricity to 0. 74105.

For the rest of the two spacecrafts ' pass over the near side of the Moon, Mattingly prepared to shift Casper to a circular orbit while Young and Duke prepared Orion for the descent to the lunar surface.

For example, NASA's workhorse space shuttle used cryogenic hydrogen / oxygen propellant as its primary means of getting into orbit, and all of the rockets built for the Soviet space program by Sergei Korolev used liquid oxygen as their oxidiser.

For a satellite in orbit around a planet, the centripetal force is supplied by gravity.

For non-circular orbits or trajectories, only the component of gravitational force directed orthogonal to the path ( toward the center of the osculating circle ) is termed centripetal ; the remaining component acts to speed up or slow down the satellite in its orbit.

For example, the Ruelle – Takens scenario describes how a periodic orbit bifurcates into a torus and the torus into a strange attractor.

For example, if there is a triple star system in which two stars orbit each other closely while a third star is in a more distant orbit, the two closely orbiting stars would be considered a component with two subcomponents.

For example, the planets that orbit the pulsar PSR 1257 are often referred to with capital rather than lowercase letters.

For example, a detector with the mass of Jupiter and 100 % efficiency, placed in close orbit around a neutron star, would only be expected to observe one graviton every 10 years, even under the most favorable conditions.

For many years economical interplanetary travel meant using the Hohmann transfer orbit.

For instance it is the most common way to transfer satellites into geostationary orbit, after first being " parked " in low earth orbit.

For instance, the motion of a spacecraft, regarding its orbit and attitude ( rotation ), is described by the relativistic theory of classical mechanics, while the analogous movements of an atomic nucleus are described by quantum mechanics.

For example, perigee and apogee are the lowest and highest parts of an orbit around Earth, while perihelion and aphelion are the closest and farthest points of an orbit around the Sun.

For any specific combination of height above the center of gravity and mass of the planet, there is one specific firing velocity ( unaffected by the mass of the ball, which is assumed to be very small relative to the Earth's mass ) that produces a circular orbit, as shown in ( C ).

# For a given orbit, the ratio of the cube of its semi-major axis to the square of its period is constant.

For example, the 3 numbers which describe the body's initial position, and the 3 values which describe its velocity will describe a unique orbit that can be calculated forwards ( or backwards ).

For example, the orbit of the Moon cannot be accurately described without allowing for the action of the Sun's gravity as well as the Earth's.

For precession of the lunar orbit see lunar precession.

For rocket-powered SSTO, the main challenge is achieving a high enough mass-ratio to carry sufficient propellant to achieve orbit, plus a meaningful payload weight.

For air-breathing SSTO, the main challenge is system complexity and associated research and development costs, material science, and construction techniques necessary for surviving sustained high-speed flight within the atmosphere, and achieving a high enough mass-ratio to carry sufficient propellant to achieve orbit, plus a meaningful payload weight.

For pure rocket approaches Tsiolkovsky's rocket equation shows that dead weight will prevent reaching orbit unless the ratio of propellant to structural mass ( called mass ratio ) is very high — between about 10 and 25 ( i. e. 24 parts propellant weight to 1 part structural weight ; depending on propellant choice ).

For example, no new evidence will demonstrate that the Earth does not orbit around the sun ( heliocentric theory ), or that living things are not made of cells ( cell theory ), that matter is not composed of atoms, or that the surface of the Earth is not divided into solid plates that have moved over geological timescales ( the theory of plate tectonics )... One of the most useful properties of scientific theories is that they can be used to make predictions about natural events or phenomena that have not yet been observed.

For missions beyond low Earth orbit NASA is building the Space Launch System and the Orion spacecraft.

For various reasons, however, poverty and personal inclination among others, he did not take a prominent part in the military operations of this period.

For practical purposes the plane of the equator and the plane of the ecliptic maintain a constant inclination to each other of approximately 23. 5 °.

For the Moon, measuring its inclination with respect to Earth's equatorial plane leads to a rapidly varying quantity and it makes more sense to measure it with respect to the ecliptic ( i. e. the plane of the orbit that Earth and Moon track together around the Sun ), a fairly constant quantity.

* For planets and other rotating celestial bodies, the angle of the axis of rotation with respect to the normal to plane of the orbit is sometimes also called inclination or axial inclination, but to avoid ambiguity can be called axial tilt or obliquity.

For Christians, concupiscence refers to what they understand as the orientation, inclination or innate tendency of human beings to long for fleshly appetites, often associated with a desire to do things which are proscribed.

For launches above low Earth orbit ( LEO ), the actual launch time can be somewhat flexible if a parking orbit is used, because the inclination and time the spacecraft initially spends in the parking orbit can be varied.

For a typical GTO with a semimajor axis of 24, 582 km, perigee velocity is 9. 88 km / s and apogee velocity is 1. 64 km / s, clearly making the inclination change far less costly at apogee.

For as the nature of foul weather lieth not in a shower or two of rain but in an inclination thereto of many days together, so the nature of war consisteth not in actual fighting but in the known disposition thereto during all the time there is no assurance to the contrary.

For Derrida, the foundation of ethics is hospitality, the readiness and the inclination to welcome the Other into one's home.

For tonal languages such as Thai, the tone is indicated by inclination and movement of the hand.

For sun-synchronous orbit the precession of the orbital plane caused by the oblateness of the Earth is a desirable feature that is part of the mission design but the inclination change caused by the gravitational forces of Sun / Moon is undesirable.

For geostationary spacecraft the inclination change caused by the gravitational forces of Sun / Moon must be counteracted to a rather large expense of fuel as the inclination should be kept sufficiently small for the spacecraft to be tracked by a non-steerable antenna.

For Sun-synchronous spacecraft having a constant geometry relative to the Sun the inclination change due to the solar gravitation is particularly large, a delta-v in the order of 1-2 m / s per year can be needed to keep the inclination constant.

For the most efficient example mentioned above, targeting an inclination at apoapsis also changes the argument of periapsis.

For more complicated manoeuvres which may involve a combination of change in inclination and orbital radius, the amount of delta v is the vector difference between the velocity vectors of the initial orbit and the desired orbit at the transfer point.

For symmetric lines, halfwidth, and full inclination width

For a good groundwave propagation, mast radiators should be built always on a large flat area with good ground conductivity and if possible without inclination.

For a nearby star with a small orbital velocity ( or whose orbital plane was almost perpendicular to our line of view ) this might merely make the star's orbit seem erratic, but for a sufficient combination of orbital speed and distance ( and inclination ), the " fast " light given off during approach would be able to catch up with and even overtake " slow " light emitted earlier during a recessional part of the star's orbit, and the star would present an image that was scrambled and out of sequence.

For Vattimo it is only when hermeneutics accepts its nihilistic destiny that " it can find in ‘ negativity ,’ in dissolution as the ‘ destiny of Being ’ … the orientating principle that enables it to realize its own original inclination for ethics whilst neither restoring metaphysics nor surrendering to the futility of a relativistic philosophy of culture " ( 1992: 119 ).
