Editing Geosynchronous orbit (section)

==Proposed orbits==

===Statite proposal===
A [[statite]] is a hypothetical satellite that uses [[Radiation pressure#Solar radiation pressure|radiation pressure]] from the Sun against a [[solar sail]] to modify its orbit.<ref name="st"/>

It would hold its location over the dark side of the Earth at a latitude of approximately 30 degrees. It would return to the same spot in the sky every 24 hours from an Earth-based viewer's perspective, so be functionally similar to a geosynchronous orbit.<ref name="st">{{cite patent |country=US |number=5183225 |status=patent |title=Statite: Spacecraft That Utilizes Sight Pressure and Method of Use |pubdate=February 2, 1993 |pridate=1989-01-09 |inventor-surname=Forward |inventor-given=Robert}}</ref><ref>{{cite magazine |magazine=New Scientist |date=March 9, 1991 |title=Science: Polar 'satellite' could revolutionise communications |issue=1759|url=https://www.newscientist.com/article/mg12917594-000-science-polar-satellite-could-revolutionisecommunications/ |access-date=October 2, 2019}}</ref>

===Space elevator===
A further form of geosynchronous orbit is the theoretical [[space elevator]]. If a mass orbiting above the geostationary belt is tethered to the earth’s surface, and the mass is accelerated to maintain an orbital period equal to one sidereal day, then since the orbit now requires more downward force than is supplied by gravity alone.  The tether will become tensioned by the extra centripetal force required, and this tension force is available to hoist objects up the tether structure.<ref>{{cite web |url=http://www.niac.usra.edu/files/studies/final_report/521Edwards.pdf |archive-url=https://ghostarchive.org/archive/20221009/http://www.niac.usra.edu/files/studies/final_report/521Edwards.pdf |archive-date=2022-10-09 |url-status=live |title=The Space Elevator NIAC Phase II Final Report |date=1 March 2003 |first=Bradley C. |last=Edwards |page=26 |publisher=[[NASA Institute for Advanced Concepts]]}}</ref>
