Joint Dark Energy Mission Facility

The Joint Dark Energy Mission Facility was a top secret NASA facility protected by S.H.I.E.L.D.. They used it as the main location for Project P.E.G.A.S.U.S..

History
This facility was the place where S.H.I.E.L.D. personnel worked on Project P.E.G.A.S.U.S.. Following Thor's visit to New Mexico, Dr. Erik Selvig was called in to the S.H.I.E.L.D. facility by Nick Fury to examine the Tesseract. It was here that Loki became aware of the Tesseract's location on Earth.

As a part of Project P.E.G.A.S.U.S., Selvig worked with other S.H.I.E.L.D. scientists in an effort to not just harness the energy of the Tesseract but to activate its cosmic potentials. The Tesseract was still in the Joint Dark Energy Mission Facility when Loki activated it from another end of space and then traveled through to the facility where he confronted the S.H.I.E.L.D. agents guarding the Tesseract. The opening of the Tesseract's portal released a large amount of energy into the underground room the cube was being held in. This energy continued to build up as Loki escaped with the Tesseract, Dr. Selvig and other S.H.I.E.L.D. agents, including Clint Barton. They were pursued by Nick Fury and Maria Hill. The explosion that followed the energy build-up destroyed the entire facility.
