Project Celestial Power was an Imperial program purported to provide sustainable energy for worlds ravaged by the Clone Wars. In truth, however, the research done by Celestial Power was being used for the Empire's superweapon, the Death Star. The program was led by Director Orson Krennic of the Imperial Corps of Engineers.
The program's research revolved mainly around kyber crystal research, and harnessing the massive amounts of energy that these crystals produced. Galen Erso was the leading scientist in this area of research. Other scientists, however, worked on varying projects such as powerful shield generators, as was the case with Reeva Demesne.
At some point during the project's development, a devastating accident occurred at the Celestial Power facility on the planet Malpaz; kyber energy output failed to be properly contained, resulting in the destruction of the entire facility, and killing tens of thousands of the planet's citizens.
Many of Celestial Power's affiliates knew nothing of the Empire's secret plans for a superweapon, and were fully convinced that they were merely helping supply sustainable energy to developing worlds. Lyra Erso, wife of Galen, grew suspicious, however, and she and her husband fled the Empire in 17 BBY, settling on the planet Lah'mu. The work on the Death Star's superlaser array was stalled for several years because of this, until Krennic was able to locate the Erso family and once again force Galen to assist in the construction of the Death Star.
