Joint Dark Energy Mission
Encyclopedia
The Joint Dark Energy Mission (JDEM) was a Einstein probe
that planned to focus on investigating dark energy
. JDEM is a partnership between NASA
and the U.S. Department of Energy.
In August 2010, the Board on Physics and Astronomy of the National Science Foundation recommended WFIRST mission, a renamed JDEM-Omega proposal which has superseded SNAP, Destiny
, and ADEPT, as the highest priority for development in the decade around 2020. This would be a 1.5-metre telescope with a 144-megapixel HgCdTe focal plane array, located at the L2 Lagrange point; the expected cost is around $1.6 billion.

Dark energy
In physical cosmology, astronomy and celestial mechanics, dark energy is a hypothetical form of energy that permeates all of space and tends to accelerate the expansion of the universe. Dark energy is the most accepted theory to explain recent observations that the universe appears to be expanding...
