Also found in: Dictionary, Wikipedia. orbital velocity The velocity of a satellite or other orbiting body at any given point in its orbit. It is also the velocity required by a satellite to enter an orbit around a body. The orbital velocity, v, is given by the expression v = √[gR...
The speed of a satellite in a circular orbit close the earth's surface is vo=gR−−−√vo=gR and escape velocity is given by ve=2gR−−−−√ve=2gR. Therefore, the additional velocity to escape is ve−vo=(2–√−1)gR−−−√ve−vo=(...
Two and half centuries later, after Newton's discoveries, in 1957, USSR launched the Earth's first artificial satellite. R-7 carrier rocket overcame the atmosphere resistance and the Earth gravity to deliver Sputnik-1 to the 577-km orbit. Escape velocity is a speed required to escape the gra...
1.The velocity at which a body revolves about another body. 2.The minimum velocity required to place or maintain a satellite in a given orbit. American Heritage® Dictionary of the English Language, Fifth Edition. Copyright © 2016 by Houghton Mifflin Harcourt Publishing Company. Published by...
A method is proposed for determining the Keplerian orbit of an artificial satellite of the earth or of a planet according to two velocity vectors given at known moments of time. The method relies on a Newtonian orbit-parameter iteration procedure. A numerical example is presented for an earth ...
Observations with the Green Bank Telescope of 21cm HI emission from the high-velocity cloud Complex H suggest that it is interacting with the Milky Way. A model in which the cloud is a satellite of the Galaxy in an inclined, retrograde circular orbit reproduces both the cloud's average ...
Figure 1: Object rotating in the orbit of a planet. Figure 1 shows how the vectors velocity and force of gravity acting on an object result in an orbital motion around a massive body if {eq}\vec v {/eq} reaches the necessary magnitude. The orbital velocity definition and circular obit ...
We investigate the mode of spinning up a low-orbit satellite in the plane of its orbit. In this mode the satellite rotates around its principal central axi... AY Bozyukov,VV Sazonov - 《Cosmic Research》 被引量: 0发表: 2007年 Binary Orbit Perturbations and the Rotational Angular Momentum ...

And with satellite records, researchers can draw solid conclusions about likely long-term trends in their behavior. Swirls play an important role in the planet’s climate. They regulate the mixing and transport of heat, carbon, biota and nutrients in the oceans. Because of this, this new resea...
