Actually, objects in geostationary orbit take a day – not a year – to complete a full orbit.   John Sheff Cambridge, MA   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of LARRY KLAES Sent: Saturday, September 13, 2003 12:57 PM To: setipublic Cc: BioAstro; europa Subject: The cheap way to the stars - by elevator   http://www.guardian.co.uk/spacedocumentary/story/0,2763,1041360,00.html   The cheap way to the stars - by escalator David Adam, science correspondent Friday September 12 2003 The Guardian A space elevator would make rockets redundant by granting cheaper access to space. At about a third of the way along the cable - 36,000km from Earth - objects take a year to complete a full orbit. If the cable's centre of gravity remained at this height, the cable would remain vertical, as satellites placed at this height are geostationary, effectively hovering over the same spot on the ground.
