Since then, thousands of satellites have been launched into orbit around the Earth.

Since the elevator would attain orbital velocity as it rode up the cable, an object released at the tower's top would also have the orbital velocity necessary to remain in geostationary orbit.

Since most of the material that went into orbit to form the Moon was thought to come from Theia, this observation was unexpected.

Since asteroids travel in an orbit not much larger than the Earth's, their magnitude can vary greatly depending on elongation.

Since in order to reach an object in orbit it is necessary to attain an extremely high velocity, their released kinetic energy alone is enough to destroy their target ; explosives are not necessary.

Since the film-return missions were usually short, they could indulge in orbits with low perigees, in the range of 100 – 200 km, but the more recent CCD-based satellites have been launched into higher orbits, 250 – 300 km perigee, allowing each to remain in orbit for several years.

Since most double stars are true binary stars rather than mere optical doubles ( as William Herschel had been the first to discover ), they orbit around one another's barycenter and slowly change position over the years.

Since the ascending node is the point of intersection between the ecliptic and the plane of the lunar orbit where the Moon is ascending from the South to the North, it is sometimes called the North node.

Since the orbit is eccentric it moves rapidly past its sun at the closest point, so its temperature would be around − 170 ° C most of the time.

Since the group action preserves the fibers of π: P → X and acts transitively, it follows that the orbits of the G-action are precisely these fibers and the orbit space P / G is homeomorphic to the base space X.

X < sub > nm </ sub > is the ( n − m ) th fourier coefficient of the classical motion at orbit n. Since X < sub > nm </ sub > has opposite frequency to X < sub > mn </ sub >, the condition that X is real becomes:

Since A ( t ) has a classical Fourier series with only the lowest frequency, and the matrix element A < sub > mn </ sub > is the ( m − n ) th Fourier coefficient of the classical orbit, the matrix for A is nonzero only on the line just

Since each electronic orbit has a magnetic moment in a magnetic field the electronic orbit will be subject to a torque which tends to make the vector parallel to the field.

Since a standard torus is an orbit of a two dimensional abelian subgroup of the Euclidean group, it follows that the cyclides are orbits of two dimensional abelian subgroups of the group of Möbius transformations, and this provides a second way to define them.

Since the two asteroidal moons appear to orbit ( as best we can tell ) in the same plane, they would occult each other once every 2. 2 days.

Since the launch trajectory was designed to insert the Pegasus satellite into the proper orbit, it differed substantially from the Saturn-Apollo I trajectory used in missions A-101 and A-102.

Since Kepler cannot resolve the planet from the star, it sees only the combined light, and the brightness of the host star seems to change over each orbit in a periodic manner.

Since the satellite was not in a geosynchronous orbit like modern communication satellites, it passed overhead quickly, and the giant antenna had to be precisely steerable to track the satellite as it moved across the sky.

Since the definition does not categorise a planet by composition or formation, but, effectively, by its location, a Mars-sized or larger object beyond the orbit of Pluto would be considered a dwarf planet, since it would not have time to clear its orbit.

Since it had not been visible in other images, it had not been possible to compute its orbit at the time, but recent comparisons have shown it to match Pallene's orbit.

Since the ring's particles are presumed to have originated from impacts ( micrometeoroid and larger ) on Phoebe, they should share its retrograde orbit, which is opposite to the orbital motion of the next inner moon, Iapetus.

Since the first two stages of the Saturn V had enough payload capability by themselves to place a pre-fabricated S-IVB workshop into the appropriate orbit, this enabled the " dry workshop " concept.

Since the Supreme Court's decision of that year this is more doubtful ; ;

( Since the time-span of the nation-state coincides roughly with the separate existence of the United States as an independent entity, it is perhaps natural for Americans to think of the nation as representative of the highest form of order, something permanent and unchanging.

Since it is not far from Viareggio, he will visit Puccini's house, as he never fails to do, to pay his respects to the memory of the composer of La Boheme, which he considers one of Puccini's masterpieces.

Since attack serves to stimulate interest in broadcasts, I added to my opening statement a sentence in which I claimed that German youth seemed to lack the enthusiasm which is a necessary ingredient of anger, and might be classified as uninterested and bored rather than angry.

Since the air is a continuum, the network of communication remains intact regardless of the positions or motions of the points ( the people ) in the net.

Since the hazards of poor communication are so great, p can be justified as a habitable site only on the basis of unusual productivity such as is made available by a waterfall for milling purposes, a mine, or a sugar maple camp.

Since the difficulty of drawing the net is great, we will merely discuss it.

Since a civilizational crisis involves also a crisis in private interests and in the ruling class, reaction is normally found among those who feel themselves to be among the ruling class.

Since civilizational change is the most difficult to perceive and analyze, it seldom is given adequate attention.

Since the slogans have little application to reality and are sanctimonious to boot, the applause is faint even in areas of the world where we should expect to find the greatest affection for free government.

Since more is known about Quiney than about any other acquaintance of Shakespeare in Stratford, his career may be followed to its sudden end in 1602.

Since the great flood of these dystopias has appeared only in the last twelve years, it seems fairly reasonable to assume that the chief impetus was the 1949 publication of Nineteen Eighty-Four, an assumption which is supported by the frequent echoes of such details as Room 101, along with education by conditioning from Brave New World, a book to which science-fiction writers may well have returned with new interest after reading the more powerful Orwell dystopia.

Since Laos is of no more purely military value to Moscow itself than it is to Washington, this approach might be expected to head off Mr. Khrushchev for the moment.

Since little is known about autism, and almost nothing has been written for the layman, we'd like to share one experienced mother's comments.

Since the work is done by hand, the only limitation, it is said, `` is that of human conception ''.

Since the apparatus is new, it requires experimentation and changes in technique.

Since the obvious is not always true, the Republican National Committee wisely analyzed its defeat of last autumn and finds that it occurred, as suspected, in the larger cities.

Since he has just shown who is top dog, he may not be ready to receive this highest honor in the gift of the Soviet people.

Since appeals to morality, to humanity, and to sanity have had such small effect, perhaps our last recourse is the deterrent example.

Since the goal of our international planners is a World Government, this Atlantic Community would mark a giant step in that direction for, once American economic autonomy is absorbed, a larger grouping is a question of time.
