Dark Energy Spectroscopic Instrument (DESI) is a scientific research instrument designed to conduct a comprehensive spectrographic survey of the universe. Installed on the Mayall Telescope at Kitt Peak National Observatory, DESI aims to map the large-scale structure of the cosmos to study dark energy, the mysterious component thought to be driving the accelerated expansion of the universe.

Probe the history of the universe's expansion through spectroscopic data.
Organization
The DESI project is managed by the Office of High Energy Physics within the U.S. Department of Energy, with primary operations run by Lawrence Berkeley National Laboratory (LBNL). It involves international collaboration, with funding from DOE, the National Science Foundation (NSF), and various international partners. The project director oversees the initiative.
The leader of the program holds the title/position of **Project Director for DESI**.
Partners
No specific partnerships are listed, but DESI involves a 600-person international scientific collaboration.
History
Construction on DESI began in 2015, with the instrument seeing first light in late 2019. After a period of commissioning and validation, DESI started its primary survey in May 2021. Key historical events include the release of the largest 3D map of the universe in 2022 and ongoing scientific discoveries related to dark energy and the cosmos's structure. The project is set to continue data collection until 2026, with plans for data analysis extending beyond that.
Funding
The initial funding for DESI's construction was $56 million from the DOE, with additional contributions from other sources bringing the total to approximately $75 million.
