Several craters are seen on the surface of 1985U1, one of several small moons of Uranus discovered by Voyager 2. The spacecraft acquired this single image -- the only close-up it obtained of any of the new moons -- on Jan. 24, 1986. At the time, Voyager was at a distance of about 500,000 kilometers (300,000 miles) from 1985U1, yielding a resolution of about 10 km (6 mi) in this clear-filter, narrow-angle image. The moon was found Dec. 30, 1985; it was the first and largest of nearly a dozen satellites discovered by the spacecraft cameras. This image shows 1985U1 to be a dark, nearly spherical object, with a diameter of about 150 km (90 mi); the dark surface reflects only 7 percent of the incident light. The picture was inserted into the Voyager encounter sequence late in its development. This image has had a complex history, having been recorded on the spacecraft tape recorder and first played back during the late afternoon of Jan. 24. An antenna-pointing problem at one of the Australian tracking stations led to loss of the data, so the image had to be transmitted a second time. It was successfully received shortly before 6 p.m. PST Jan. 26. The Voyager project is managed for NASA by the Jet Propulsion Laboratory.
