The bright cirrus-like clouds of Neptune change rapidly, often forming and dissipation over periods of several to tens of hours.  In this sequence spanning two rotations of Neptune (about 36 hours) Voyager 2 observed cloud evolution in the region around the Great Dark Spot (GDS) at an effective resolution of about 100 km (62 miles) per pixel.  The surprisingly rapid changes which occur over the 18 hours separating each panel shows that in this region Neptune's weather is perhaps as dynamic and variable as that of the Earth.  However, the scale is immense by our standards--the Earth and the GDS are of similar size -- and in Neptune's frigid atmosphere, where temperatures are as low as 55 degree Kelvin  (-360F), the cirrus clouds are composed of frozen methane rather than Earth's crystalse of water ice.

Range :  12 million km (7.5 million miles) Resolution 110 km (68 miles) per pixel. These 2 images of Neptune were taken by Voyager 2's narrow-angle camera.  During the 17.6 hours between the left and right images, the Great Dark Spot, at 22 degrees south latitude (left of center), has completed a little less than one rotation of Neptune.  The smaller dark spot, at 54 south, completed a little more than one rotation, as can be seen by comparing its relative positions in the two pictures.  The Great Dark Spot and the smaller spot have a relative velocity of 100 meters per second (220 miles an hour).  The light and dark bands circling Neptune indicate predominantly zonal (east-west) motion.  The diffuse white feature north of the Great Dark Spot is near Neptune's equator, and rotates with about the same period as the Great Dark Spot.  Streak of bright clouds at the south edge, and just east of the Great Dark Spot, are its constatnt companions, and change the details of their appearance, often within a few hours.  Changing brightness of the cloud streaks could be a result of vertical mortions. ARC-1989-A89-7006

Range :  4.7 million km (2.9 million mi.) Nereid, the last satellite of Neptune to be discovered before Voyager's recent discoveries, was first seen by Gerard Kuiper in 1949.  Until this Voyager 2 image was obtained, all that was known about Nereid was its orbital parameters and intrinsic brightness.  With a resolution of 43 kilometers (26.6 mi.) per  pixel, this image has sufficient detail to show the overall size and albedo.  Nereid is about 170 km (105 mi.) across and reflects about 12 percent of the incident light. ARC-1989-A89-7033

P-34709 Range: 157,000 kilometers (98,000 miles) This Voyager 2 high resolution color image, taken 2 hours before closest approach, provides obvious evidence of vertical relief in Neptune's bright cloud streaks. These clouds were observed at a latitude of 29° N near Neptune's east terminator. The linear cloud forms are stretched approximately along lines of constant latitude and the sun is toward the lower left. The bright sides of the clouds that face the sun are brighter than the surrounding cloud deck because they are more directly exposed to the sun. Shadows can be seen on the side directly opposite the sun. These shadows are less distinct at short wavelengths (violet filter) and more distinct at long wavelengths (orange filter). This can be understood if the underlying cloud deck on which the shadow is cast is at a relatively great depth, in which case scattering by molecules in the overlying atmopsphere will diffuse light into the shadow. Because molecules scatter blue light much more efficiently than red light, the shadows will be darkest at the longest (reddest) wavelengths, and will appear blue under white illumination. The resolution of this image is 11 kilometers (6.8 miles per pixel). The width of the cloud streaks range from 50 to 200 kilometers (31 to 124 miles), and their shadow widths range from 30 to 50 kilometers (18 to 31 miles). Cloud heights appear to be of the order of 50 kilometers (31 miles). This corresponds to 2 scale heights. ARC-1989-AC89-7038

P-34698 These Voyager 2 images of satellite 1989N2 at a resolution of 4.2 kilometers (2.6 miles) per pixel reveals it to be an irregularly shaped, dark object. The satellite appears to have several craters 30 to 50 kilometers (18.5 to 31 miles) across. The irregular outline suggests that this moon has remained cold and rigid throughout much of its history. It is about 210 by 190 kilometers (130 by 118 miles), about half the size of 1989N1. It has a low albedo surface reflecting about 5 percent of the incident light. ARC-1989-A89-7035

P-34681 Range: 870,000 kilometers (540,000 miles) This image of Neptune's irregularly-shaped satellite 1989N1 taken by Voyager 2 shows a resolution of 8 kilometers (5 miles) per pixel. The satellite has an average radius of about 200 kilometers (120 miles) and is uniformly dark with an albedo of about 6 percent. The irregular shape suggests that 1989N1 has been cold and rigid throughout its history and subject to significant impact cratering. ARC-1989-A89-7034

This image is the first full picture showing both asteroid 243 Ida and its newly discovered moon to be transmitted to Earth from NASA's Galileo spacecraft--the first conclusive evidence that natural satellites of asteroids exist.  Ida is the large object to the left, about 56 kilometers (35 miles long).  Ida's natural satellite is the small object to the right.  This portrait was taken by Galileo's charge-coupled device (CCD) camera on August 28, 1993, about 14 minutes before the spacecraft's closest approach to the asteriod, from a range of 10,870 kilometers (6,755 miles).  Ida is a heavily cratered, irregularly shaped asteroid in the main asteroid belt between Mars and Jupiter-- the 243rd asteroid to be discovered since the first one was found at the beginning of the 19th century.  It is a member of a group of asteroids called the Koronis family.  The small satellite, which is about 1.5 kilometers (1 mile) across in this view, has yet to be given a name by astronomers.  It has been provisionally designated '1993 (243) 1' by the International Astronomical Union.  (The numbers denote the year the picture was taken, the asteroid number and the fact that it is the first moon of Ida to be found.)  ALthough the satellite appears to be 'next' to Ida it is actually slightly in the foreground, closer to the spacecraft than Ida.  Combining this image with data from Galileo's near-infrared mapping spectrometer, the science team estimates that the object is about 100 kilometers (60 miles) away from the center of Ida.  This image is one of a six-frame series taken through different color filters, this one in green.  The spatial resolution in this image is about 100 meters (330 feet) per pixel.  The Galileo spacecraft flew past Ida en route to its final destination, Jupiter, where it will go into orbit in December 1995.  The Jet Propulsion Laboratory manages the galileo Project for NASA's Office of Space Science. (JPL ref. No. P-43731) ARC-1994-A91-2018
