Project P.E.G.A.S.U.S.
Project P.E.G.A.S.U.S. was the name of the joint project between S.H.I.E.L.D, NASA, and the U.S. Airforce to study the Tesseract and harness its power.
In the 1980s, project leader Wendy Lawson, who was in reality a Kree named Mar-Vell, used the Tesseract's energy to create the Light-Speed Engine in an attempt to end the Kree-Skrull War. Following Mar-Vell's death in 1989, the project was terminated.
In the aftermath of the Battle of Puente Antiguo the World Security Council and S.H.I.E.L.D. reactivated P.E.G.A.S.U.S. to continue their attempts in harnessing the power of the Tesseract, until the actions of Loki rendered the project defunct.
