NASA announced that it had signed a memorandum of understanding (MOU) with the U.S. Department of Energy (DOE) for the implementation of the Joint Dark Energy Mission (JDEM). JDEM would measure the universe’s expansion with high precision, making it the first space- based observatory to study the nature of dark energy, specifically. Scientists hoped that understanding the properties of dark energy, which makes up approximately 70 percent of the total mass energy of the universe, would help them learn more about how galaxies form and gain their mass. NASA and DOE signed the MOU in accordance with recommendations of a 2007 study issued by the jointly funded Beyond Einstein Program Assessment Committee. The Committee had recommended that NASA should develop and launch JDEM first, out of the five proposed missions in NASA’s Beyond Einstein Program.
