Original sentence: At this point in time, a compromise solution has been adopted: NASA funds space-based operations such as the Hubble Space Telescope (HST), Chandra (an X-ray satellite telescope), and the Spitzer Space Telescope (an infrared satellite telescope), and the NSF funds ground-based operations such as the Atacama Large Millimeter Array (ALMA, run by the National Radio Astronomy Observatory, NRAO), and Kitt Peak (located near Tucson, AZ).In particular, in the fields of space exploration and astronomical study, it is often unclear what aspects of these fields should be handled (and funded) by the NSF, and what aspects should be in the realm of the National Aeronautics and Space Administration (NASA).In practice, the NSF has traditionally competed for funding with defense research agencies like the Defense Advanced Research Projects Agency, the Office of Naval Research, and the Air Force Office of Scientific Research.See also  Criticism of the NSF below.The NSF is considered by some historians of science to be an unsatisfactory compromise between too many clashing visions of the purpose and scope of the federal government
Edited sentence: At this point in time, an uneasy truce has developed, with NASA paying for space-based operations such as the Hubble Space Telescope (HST), Chandra (an X-ray satellite telescope), and the Spitzer Space Telescope (an infrared satellite telescope), and the NSF paying for ground-based operations such as the Atacama Large Millimeter Array (ALMA, run by the National Radio Astronomy Observatory, NRAO), and Kitt Peak (located near Tucson, AZ).In the current (and past) age of space exploration and astronomical study, it is often unclear what aspects of these fields should be handled (and funded) by the NSF, and what aspects should be in the realm of the National Aeronautics and Space Administration (NASA).NSF has traditionally competed for funding with defense research agencies like the Defense Advanced Research Projects Agency, the Office of Naval Research, and the Air Force Office of Scientific Research.The NSF is generally considered by historians of science to be an inept compromise between too many clashing visions of the purpose and scope of the federal government
