Big Questions for JDEM

NASA and the U.S. Department of Energy will support a probe to investigate dark energy, the Joint Dark Energy Mission (JDEM). The Joint Dark Energy Mission will be an observatory containing a telescope and appropriate focal plane instruments. This mission is part of SMD's Physics of the Cosmos program.

What are the origin, evolution and fate of the Universe?

Two of the most profound questions that all cultures, both past and present, have asked are: where did we come from and what is our destiny? Throughout history philosophers, theologians, and scientists have debated these questions. NASA Science seeks to provide quantitative information pertinent to these basic elements of human curiosity by enabling scientists and engineers to construct instruments and make measurements on these topics that were once the purview of thought experiments only.
