Why is the DOE getting so involved in astronomy&#x2F;cosmology?  I know they are big supporters of science, but normally that science has some relationship to energy or atomic weapons (example: National ignition facility).  I don&#x27;t see how a telescope to map stars and measure dark energy fits into their mandate.<p>Or is this thing part of the new space fence?  Is it to be located in the south to spot spysats and&#x2F;or debris in polar orbits?
