=== Transmission to Earth ===
Hubble data was initially stored on the spacecraft. When launched, the storage facilities were old-fashioned reel-to-reel [[tape drive]]s, but these were replaced by [[solid-state drive|solid state]] data storage facilities during servicing missions{{nbsp}}2 and 3A. About twice daily, the Hubble Space Telescope radios data to a satellite in the [[geosynchronous]] [[Tracking and Data Relay Satellite System]] (TDRSS), which then downlinks the science data to one of two 60-foot (18-meter) diameter high-gain microwave antennas located at the [[White Sands Test Facility]] in [[White Sands, New Mexico]].<ref name="Telemetry">{{cite web |title=Team Hubble |url=http://hubblesite.org/the_telescope/team_hubble/ |url-status=dead |archive-url=https://web.archive.org/web/20121028183242/http://hubblesite.org/the_telescope/team_hubble/ |archive-date=October 28, 2012 |access-date=November 5, 2012 |website=HubbleSite.org |publisher=[[Space Telescope Science Institute]]}}</ref> From there they are sent to the Space Telescope Operations Control Center at Goddard Space Flight Center, and finally to the Space Telescope Science Institute for archiving.<ref name="Telemetry" /> Each week, HST downlinks approximately 140 gigabits of data.<ref name="hubblesite-facts" />
