91 Consequently the force of gravity at perigee is not enough to hold it in a circular orbit. 92 Apolune is the point on the orbit where the spacecraft is furthest from the centre of the Moon. 93 All of these are complicated factors and the general effect on an orbit requires careful calculation. 94 This constant is important because it fixes the sizes, period and energy of an electron's orbit in an atom. 95 These satellites are in geostationary orbit and the images that they provide are used primarily in weather forecasting applications. 96 Only those with extremely short attention spans or those in orbit can appreciate all the chopping and changing. 97 If the Solar System existed in total isolation, those comets would continue to orbit in perfectly stable fashion. 98 All of the Amor asteroids cross the orbit of Mars and could collide with it. 99 Cosmonaut Yuri Gagarin was the first man to orbit the Earth. 100 It was placed in an eccentric, high-inclination orbit around Venus by the firing of a small rocket engine. 101 Both target and projectile orbit the primary. 102 Orbit right ( left ) from your present position. 103 Skylab continued to orbit for five more years. 104 Scientists estimate that Quaoar takes about 288 years to orbit the sun. 105 As one of the important parts in the pipe assembly of a satellite propulsion system, the orbicular seal joint is related with the reliability and service life of the satellite working in orbit. 106 Explorer One went into a higher orbit than either Sputnik. 107 All the relativistic effects except spin - orbit coupling are considered. 108 On February 20, 1962, John Glenn became thethird American in space and the first to make a full orbit of the Earth. 109 This paper first sums up the main problem about orbit prediction of an artificial earth satellite. 110 The Ion Cannon is approaching target orbit above Sarajevo. Please stand by for Ion Cannon control. 111 Seen here with its three known moons, Charon, Nix, and Hydra, Pluto is a member of a group of objects that orbit in a disklike zone beyond the orbit of Neptune called the Kuiper belt. 112 And if that wasn't bad enough, space writer Andrew Chaikin's description of going No. 2 in orbit is even worse. 113 John Glenn, the first American to orbit the earth, carried pureed applesauce in squeezable tubes on his initial space flight. 114 But the satellites will arrive with less relative speed than spacecraft making the trip in three days, which means less fuel will be needed to brake and drop into lunar orbit. 115 A resurrected satellite, carrying the hopes of climate scientists, successfully made a second attempt to reach orbit today from the Baikonur cosmodrome in Kazakhstan. 116 " Debris in orbit, " Yang said. " Metallic structures . Unknown alloy composition on spectroscopic analysis. " 117 Sputnik was the first man - made satellite to orbit the earth. 118 Yet these observations provide the barest amount of information: just the size and ellipticity of the planet's orbit and a lower limit on its mass. 119 Boeing has built one third of the approximately 250 satellites in geosynchronous orbit today. 120 Russia has more than 100 satellites in orbit. Two-thirds of them are military or dual-purpose spacecraft, RIA Novosti said.
