WebThe orbital velocity needed to maintain a stable low Earth orbit is about 7.8 km/s, but reduces with increased orbital altitude. Calculated for circular orbit of 200 km it is 7.79 km/s and for 1500 km it is 7.12 km/s. [3] The delta-v needed to achieve low Earth orbit starts around 9.4 km/s. WebOct 1, 2024 · A satellite orbits in circular motion at an altitude of 5000 kilometers above the surface of the Earth.

Web1. (a) The orbital period can be calculated using the equation T = 2πr r r gR2 e where r = Re +h where Re = 6378km is the earth’s radius, r is the satellites distance from the earth’s … WebAug 7, 2024 · It varies roughly exponentially with altitude, doubling every 5 or 10 km. At 200 km a spacecraft might be able to stay for a few weeks but at 100 km it may not even last one orbit; as soon as it loses a little velocity it drops lower where the density is higher and so it loses velocity even more quickly. – uhoh Aug 8, 2024 at 2:48 4 WebSep 22, 2004 · = 2,084 840 km/day. Each day has (24)(3600) = 86400 seconds, so the orbital distance covered by Mars each second is Distance-per-second is of course the definition of velocity. Therefore V3 = 24.130 km/s Comparing to V2 = 21.481 km/s . we see that Mars is the one moving faster, and will be overtaking the spaceship. incarnation\\u0027s 5r
