Since the energy ultimately comes from fuel, these considerations mean that rockets are mainly useful when a very high speed is required, such as ICBMs or orbital launch.

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 orbital energies are unique to an atom of a specific element, analysis of the ejected electrons can yield information about the chemical composition of a surface.

Since the strong force is a short-range interaction, these effects are strongest if the atomic orbital involved is close to the nucleus, when the energy levels involved may broaden or disappear because of the absorption of the hadron by the nucleus.

Since the Juno I was the same height as the Jupiter-C ( 21. 2 meters ), with the added fourth stage being hidden inside the shell, this vehicle which successfully launched the first orbital satellite of the United States is often incorrectly referred to as a Jupiter-C.

Since EchoStar also owned the adjacent 119 ° W orbital location it developed the Dish 500 to receive the signals of both orbital locations using one Dish and an innovative dual-LNB assembly.

Since energy is conserved, the total specific orbital energy

Since it is, actually, a binary star, its highly distorted shape may cause non-negligible departures of the companion's orbital trajectory with respect to a Keplerian ellipse.

Since wireless was not invented yet in 1889, communication between Earth and Mars is handled by orbital heliograph stations.

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 area of the entire orbital ellipse is swept out in one orbital period, is equal to twice the area of the ellipse divided by the orbital period, giving the equation

Since the atmosphere at either end is moving at its local orbital speed, the ends of trees are subject to a constant hurricane-force wind.

Since the orbital momentum changes from zero to one in this process, if the process is to conserve the total parity then the products of the intrinsic parities of the initial and final particles must have opposite sign.

Since Phobos orbits Mars faster than the planet itself rotates, tidal forces are slowly but steadily decreasing its orbital radius.

Since the total flight-time difference between " fast " and " slow " lightsignals would be expected to scale linearly with distance in simple emission theory, and the study would ( statistically ) have included stars with a reasonable spread of distances and orbital speeds and orientations, deSitter concluded that the effect should have been seen if the model was correct, and its absence meant that the emission theory was almost certainly wrong.

Since this style of reactor produces high power without heavy castings to contain high pressures, it is well suited to spacecraft.

Since a mass driver could use any type of mass for reaction mass to move the spacecraft, a mass driver or some variation seems ideal for deep-space vehicles that scavenge reaction mass from found resources.

Since the space shuttle fleet has retired ( while Hubble still has many years of service life ahead ), there will be no existing or planned spacecraft capable of returning the Hubble to Earth intact, so it is now very unlikely it will ever be on the ground again.

Since the intensity of cosmic rays is much larger outside the Earth's atmosphere and magnetic field, it is expected to have a major impact on the design of spacecraft that can safely transport humans in interplanetary space.

Since many U. S. spacecraft are launched from both the station and the Kennedy Space Center on Merritt Island, the terms " Cape Canaveral ," " Canaveral ", or " the Cape " have become metonyms that refer to both as the launch site of spacecraft.

Since the late 2000s, high-definition photos taken by the LROC spacecraft of the Apollo landing sites have captured the lander modules and the tracks left by the astronauts.

Since no spacecraft can yet aerobrake safely on its own, this requires constant attention from both human controllers and the Deep Space Network.

Since the hub is at the rotational axis of the station, it experiences the least artificial gravity and is the easiest location for spacecraft to dock.

Since a gravity assist maneuver can change the speed of a spacecraft without expending propellant, if and when possible, combined with aerobraking, it can save significant amounts of propellant.

Since they need no external material to form their jet, rocket engines can be used for spacecraft propulsion as well as terrestrial uses, such as missiles.

Since McDivitt and White were prohibited from naming their spacecraft, they decided to put the American flag on their suits, the first astronauts to do so, although Soviet crews wore the Cyrillic " СССР " on their spacesuit helmets.

Since it takes time for a radio transmission to reach the spacecraft from the earth, the usual operation of a spacecraft is done via an uploaded commanding script containing SCET markers to ensure a certain timeline of events.

Since the spacecraft would not decelerate upon reaching Barnard's Star, Daedalus would carry 18 autonomous sub-probes that would be launched between 7. 2 and 1. 8 years before the main craft entered the target system.

Since the spacecraft was spin-stabilized, the spin resulted in a bias in the Doppler signal due to the spacecraft antenna pattern spinning with respect to the Earth station of 0. 417 Hz ( 27. 3 mm / s ) for the omnidirectional antenna, and − 0. 0172 Hz (− 1. 12 mm / s ) for the medium gain antenna.

Since 1945, the Wallops Test Range has launched more than 14, 000 research vehicles in the quest for information on the flight characteristics of airplanes, launch vehicles, and spacecraft ; and to increase the knowledge of the Earth's upper atmosphere and the near-space environment.

Since the spacecraft were flying with almost no additional stabilization thrusts during their " cruise ", it is possible to characterize the density of the solar medium by its effect on the spacecraft's motion.

Since the telescope could not be aimed, the spacecraft was set in a slow spin to scan the celestial sphere.

Since propellant is usually the biggest mass on many spacecraft, this reduces launch costs.

Since interplanetary spacecraft spend a large period of time in the heliocentric orbit between the planets, which are at relatively large distances away, the patched-conic approximation is much more accurate for interplanetary trajectories than for translunar trajectories.

Since very few spacecraft ever return to the Earth intact, flight spares are useful for posterity, and may end their lives in museums.

Since terraforming cannot be expected as a near-term solution, habitable structures on Mars would need to be constructed with pressure vessels similar to spacecraft, capable of containing a pressure between a third and a whole bar.

Since its publishing, Little Nemo has had an influence on other artists, including Alan Moore, in Miracleman # 4, when the Miracleman family end up in a palace called " Sleepy Town ," which has imagery similar to Little Nemo's.

Since this use of the term conflicts with that of ordinary language, some psychologists have preferred to describe this process as " imaging " or " imagery " or to speak of it as " reproductive " as opposed to " productive " or " constructive " imagination.

Since the 1990s, computer generated imagery ( CGI ) has come to the forefront of special effects technologies.

Since 1985, commercial vendors of satellite imagery have entered the market, beginning with the French SPOT satellites, which had resolutions between 5 and 20 metres.

Since the 1980s Florida State University has forged a relationship with the Seminole Tribe of Florida, who have given the school their blessing to use the Seminole and Osceola imagery.

Since 1991 he has painted some of the rich imagery for Games Workshop and their unique Warhammer World, in addition to painting covers for the Black Library, an offshoot of Games Workshop, and gaming cards for Sabertooth Games.
