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'''.

Additional technology used to benefit astronomy includes [[w:Sounding rockets|sounding rockets]] which may carry gamma-ray, X-ray, ultraviolet, and infrared detectors to high altitude to view individual sources and the background for each wavelength band observed.⏎

With the advent of lofting technology comes the possibility of placing an observatory as a free floating yet when necessary either a geostationary, rotating, or fixed form in orbit. The TRACE spacecraft imaged at above right is in its cleanroom during assembly prior to launch.
