is AS17-150-23069 (Magazine 150-LL). It shows a closeup view of the most southern section of Mare Serenitatis on the eastern part of the moon's near side. Also visible are Promontorium Archerusia (the oblong system of hills), Brackett (the shallow crater), Dorsum Nicol (the wrinkle ridge), Rimae Plinius (the three grooves), and the northern part of the rim of the pronounced crater Plinius. On the cover of the album, the upper margin of the orbital Hasselblad photograph is rotated 90 degrees to the right. Also visible on the cover photograph is the brightness of Mare Serenitatis to the north (rightward) of the shallow crater Brackett and Rimae Plinius. When observed through a telescope, this region shows a subtle yellowish or tannish grey color. The region to the south (leftward) of Mare Serenitatis shows a subtle bluish grey, which is the overall color of Mare Tranquillitatis. On the cover of the album, these subtle real colors are not reproduced, only the abrupt change of brightness is visible. Hasselblad photograph AS17-150-23069 is also seen as Figure 59 in Part 1 of Chapter 4 (The Maria) in NASA SP-362: Apollo Over The Moon, a view from orbit. Small photograph The small photograph on the back side of the LP cover is AS14-73-10116, made during the mission of Apollo 14 in February 1971. It shows small sections of the walled plains Fra Mauro and Bonpland. The grooves on the floors of both walled plains are known as Rimae Parry. The distinct and largest one of the small bowl shaped craters in this photograph is Fra Mauro F. Music The album contains a variety of styles. "Under Stars", "The Secret Place", "Matta", "Signals", "Under Stars II", and "Stars" are all dark, complicated textures similar to those on Eno's previous album Ambient 4/On Land. "An Ending (Ascent)", "Drift", and "Always Returning" are smoother electronic pieces. "Silver Morning", "Deep Blue Day", and "Weightless" are country–inspired ambient pieces featuring Daniel Lanois on pedal steel guitar. Country music, which Eno listened to as a child in Woodbridge on American armed forces radio, was used to "give the impression of weightless space." "Under Stars" is a recurring theme in the album, first appearing as an ambient electronic bed behind a treated guitar. "Under Stars II" is the same composition, but with different effects and treatments. "Stars" is the pure background texture without the guitar. The track "An Ending (Ascent)" was sampled
