The spacecraft cemetery, known more formally as the South Pacific Ocean (ic) Uninhabited Area, [ 1 ][ 2 ] is a region in the southern Pacific Ocean east of New Zealand, [ 3 ] where spacecraft that have reached the end of their usefulness are routinely crashed. The area is roughly centered on " Point Nemo ", the oceanic pole of inaccessibility ...
A graveyard orbit is used when the change in velocity required to perform a de-orbit maneuver is too large. De-orbiting a geostationary satellite requires a delta-v of about 1,500 metres per second (4,900 ft/s), whereas re-orbiting it to a graveyard orbit only requires about 11 metres per second (36 ft/s).
The satellites are pinpoint, while stars have created star trails due to Earth's rotation. A geostationary orbit, also referred to as a geosynchronous equatorial orbit[ a ] (GEO), is a circular geosynchronous orbit 35,786 km (22,236 mi) in altitude above Earth's equator, 42,164 km (26,199 mi) in radius from Earth's center, and following the ...
Collision avoidance (spacecraft) Spacecraft collision avoidance is the implementation and study of processes minimizing the chance of orbiting spacecraft inadvertently colliding with other orbiting objects. The most common subject of spacecraft collision avoidance research and development is for human-made satellites in geocentric orbits.
A satellite ground track may be thought of as a path along the Earth's surface that traces the movement of an imaginary line between the satellite and the center of the Earth. In other words, the ground track is the set of points at which the satellite will pass directly overhead, or cross the zenith, in the frame of reference of a ground ...
Speaking of OGs — the film is largely and undeniably a tribute to the fourth member of the original Ghostbusters (1984) and Ghostbusters II (1989) crew: the late, great Harold Ramis, who so ...
