Observatory end-to-end science operations is the overall process starting with a scientific question, represented by a proposal requesting observing time; ending with the analysis of observation data addressing that question; and including all of the intermediate steps needed to plan, schedule, obtain, and process these observations. Increasingly complex observing facilities demand a highly efficient science operations approach and at the same time must be user friendly to the astronomical user community and enable the highest possible scientific return. Therefore, this process is supported by a collection of tools. We describe the overall end-to-end process and its implementation for the three upcoming Extremely Large Telescopes (ELTs): European Southern Observatory’s ELT, the Thirty Meter Telescope, and the Giant Magellan Telescope.

The European Southern Observatory (ESO) designs, builds, and operates world-class observatories on the ground and promotes international collaboration in astronomy. Established as an intergovernmental organization in 1962, ESO is currently supported by 16 member states (Austria, Belgium, the Czech Republic, Denmark, France, Finland, Germany, Ireland, Italy, the Netherlands, Poland, Portugal, Spain, Sweden, Switzerland, and the United Kingdom), along with the host state of Chile and with Australia as a Strategic Partner. ESO operates three observing sites: at Paranal, ESO operates the Very Large Telescope and its Very Large Telescope Interferometer, as well as two survey telescopes, VISTA and the VLT Survey Telescope. Also, at Paranal, ESO will host and operate the Cherenkov Telescope Array South. Together with international partners, ESO operates two millimeter and submillimeter facilities, APEX and ALMA on Chajnantor. At Cerro Armazones, ESO is building its ELT. The US Extremely Large Telescope Program (US-ELTP) is a joint effort of three organizations: Thirty Meter Telescope International Observatory (TIO), GMTO Corporation, and NSF’s NOIRLab. This work is supported by the National Science Foundation through Cooperative Agreement AST-1546092 and Cooperative Support Agreement AST-2013059. NSF’s NOIRLab is the national center for ground-based nighttime astronomy in the United States and is operated by the Association of Universities for Research in Astronomy (AURA) under a cooperative agreement with the National Science Foundation Division of Astronomical Sciences.
