The next phase of spending has begun in a massive 3D sky-mapping project designed to measure the light of millions of galaxies. The fabrication of the robots that will be used in the collection of this light is scheduled to allow observations to begin in January of 2019. The data gathered will give scientists a more complete picture of the way in which the universe is expanding and hopefully provide answers to the many questions about the nature of the pervasive dark energy which will help better understand not only where the universe has been, but where it might be going.
