Astronomy is performed by location and is subject to local conditions. The shapes and sizes of observatories have changed over time, as have their altitude. The motivations for putting an observatory manned or unmanned at different altitudes has led to a great variety in '''lofting technology'''.

The second image down on the left is a night launch of ESSA 9 aboard a Delta E1 rocket from Cape Canaveral, Florida. The launch occurred at 07:47 UTC (02:47 EDT) on February 26, 1969. The spacecraft was placed in a sun-synchronous orbit of 101.4° inclination. Immediately after launch ESSA-9 had a perigee of 1,427.0 kilometers (886.7 mi) and an apogee of 1,508.0 kilometers (937.0 mi), giving it an orbital period of 115.2 minutes, or a mean motion of 12.5 orbits per day.<ref name="Launch">[http://nssdc.gsfc.nasa.gov/nmc/spacecraftOrbit.do?id=1969-016A Launch info]</ref> ESSA-9 operated for 1,726 days before it was deactivated in November 1972.
