S74-20831 (November 1973) --- A group of astronauts and their cosmonaut hosts are photographed sightseeing on Red Square in the heart of Moscow during a tour of the Soviet capital. The Americans were in the USSR to participate in Apollo-Soyuz Test Project familiarization training on the Soyuz systems at the Cosmonaut Training Center (Star City) near Moscow. Astronaut Thomas P. Stafford (light coat, black cap), commander of the American ASTP crew, was head of the U.S. delegation to Star City. Astronaut Eugene A. Cernan (on Stafford?s left, light coat) is the Special Assistant to the American Technical Director of ASTP. The sightseeing group is walking in the direction of Lenin?s Mausoleum. The structure in the background is the Cathedral of the Intercession (St. Basil?s) Museum. The historic Kremlin complex is to the right. PHOTO COURTESY: USSR ACADEMY OF SCIENCES

This is a vertically polarized L-band image of the southern half of Moscow, an area which has been inhabited for 2,000 years. The image covers a diameter of approximately 50 kilometers (31 miles) and was taken on September 30, 1994 by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar aboard the space shuttle Endeavour. The city of Moscow was founded about 750 years ago and today is home to about 8 million residents. The southern half of the circular highway (a road that looks like a ring) can easily be identified as well as the roads and railways radiating out from the center of the city. The city was named after the Moskwa River and replaced Russia's former capital, St. Petersburg, after the Russian Revolution in 1917. The river winding through Moscow shows up in various gray shades. The circular structure of many city roads can easily be identified, although subway connections covering several hundred kilometers are not visible in this image. The white areas within the ring road and outside of it are buildings of the city itself and it suburban towns. Two of many airports are located in the west and southeast of Moscow, near the corners of the image. The Kremlin is located north just outside of the imaged city center. It was actually built in the 16th century, when Ivan III was czar, and is famous for its various churches. In the surrounding area, light gray indicates forests, while the dark patches are agricultural areas. The various shades from middle gray to dark gray indicate different stages of harvesting, ploughing and grassland. http://photojournal.jpl.nasa.gov/catalog/PIA01752

STS042-80-000AV (22-30 Jan. 1992) --- Moscow is arranged as a series of concentric transportation routes crossed by straight spokes which lead away from the Kremlin at the city center. One of the inner rings, the Garden Ring, follows the line of the Sixteenth Century city wall and moat. Both this and the outer ring of the Moscow Circular Motorway can be seen. The Kremlin, established in the Twelfth Century, lies on the north bank of the winding Moskva River. Very large high-rise buildings were erected after World War II. Clusters of these produce a coarser pattern and can be detected at two points within the outer ring road. Of the five airports surrounding the city, Vnukovo Airport to the south is easily distinguished, and Sheremetyevo to the west can also be delineated. The once-secret Ramenskoye Airport, with the longest runways in the world, lies under clouds to the northeast.

STS068-236-027 (30 September-11 October 1994) --- The STS-68 crewmembers used a 70mm camera to photograph this early morning nadir view of wheel-shaped Moscow. Star City, Russia facility, north of the city, is among the detail seen in the view, photographed from 115 nautical miles above Earth. Six NASA astronauts spent a week and a half aboard the Space Shuttle Endeavour in support of the Space Radar Laboratory 2 (SRL-2) mission.

ISS039-E-009160 (2 April 2014) --- This nighttime view featuring the aurora borealis, the moon and Moscow was photographed by an Expedition 39 crew member on the International Space Station. A thin green line of the aurora borealis crosses the top of this image. The moon appears as a white disc just above the aurora. Airglow appears as a blue-white cusp on Earth's limb. Russia's capital city Moscow makes a splash of yellow (lower left), with its easily recognized radial pattern of highways. Other cities are Nizhni Novgorod (lower center) 400 kilometers from Moscow, St. Petersburg (left) 625 kilometers from Moscow, and Finland?s capital city Helsinki.
