ISS020-E-028072 (5 Aug. 2009) --- Sevastopol, Ukraine is featured in this image photographed by an Expedition 20 crew member on the International Space Station. The port city of Sevastopol is located in southernmost Ukraine on the Crimean Peninsula. The city is an important naval base due to the numerous inlets and bays along the coastline (bottom center). During the Cold War, the city was the base of the Soviet Black Sea Fleet, but now services vessels of both the Ukraine and Russia. The main economy of the city is based on trade and shipbuilding, but Sevastopol is also a popular tourist and resort destination for visitors from the Commonwealth of Independent Countries (formed from former Soviet Republics). This photograph highlights the jagged coastline of the southern Crimean Peninsula and the various docking areas of Sevastopol. The urban area is light gray, and is bounded to the north and west by the Black Sea, to the south by vegetated (light green) and fallow (tan) agricultural fields, and to the east by the city of Inkerman and green vegetated uplands to the northwest of the Crimean Mountains. The city of Balaklava to the south houses another relic of the Cold War ? an underground Soviet submarine base that is now open to the public as a monument. The Chernaya River issues into the Black Sea near Inkerman, flowing into the Sevastopol Inlet to the west.

S75-25077 (May 1975) --- A photographic copy of a painting made by cosmonaut Aleksey A. Leonov, commander of the Soviet ASTP first (prime) crew. This symbolic artwork, representing a Soviet Soyuz spacecraft docking in Earth orbit with an American Apollo spacecraft, was finished in May 1974. The sketch for the painting was made in 1973 following the signing of the space agreement between the United Stated and the Soviet Union. Leonov said that his painting symbolizes the new type of international cooperation of working together in space. The original painting, which measures 80 centimeters by 160 centimeters (1 cm. = 0.39 in.), is on display in a museum in the city of Baku on the Caspian Sea. In making the sketch for the painting Leonov used a model of an earlier Soyuz spacecraft and a picture of an Apollo spacecraft. Later, he obtained a model of an Apollo which helped him check the configuration of the American spacecraft. The tanks on the Docking Module are no longer exposed on the current DM configuration, he noted. Also, this would not be an exact view of the sun as seen from Earth orbit. Leonov took artist license in stressing the symbolism in his artwork. The Soyuz is represented smaller in the painting than it actually is, Leonov added.

CAPE CANAVERAL, Fla. – The Apollo Soyuz Test Project Saturn IB launch vehicle thundered away from KSC’s Launch Complex 39B at 3:50 p.m. today. Aboard the Apollo Command Module were ASTP Astronauts Thomas Stafford, Vance Brand and Donald Slayton. The astronauts will rendezvous and dock with a Soyuz spacecraft, launched this morning from the Baikonur launch facility in the Soviet Union, carrying Soviet cosmonauts Aleksey Leonov and Valeriy Kubasov. The first international crewed spaceflight was a joint U.S.-U.S.S.R. rendezvous and docking mission. The Apollo-Soyuz Test Project, or ASTP, took its name from the spacecraft employed: the American Apollo and the Soviet Soyuz. The three-man Apollo crew lifted off from Kennedy Space Center aboard a Saturn IB rocket on July 15, 1975, to link up with the Soyuz that had launched a few hours earlier. A cylindrical docking module served as an airlock between the two spacecraft for transfer of the crew members. Photo credit: NASA

This Magellan image mosaic shows the impact crater Golubkina, first identified in Soviet Venera 15/16 data. The crater is names after Anna Golubkina (1864-1927), a Soviet sculptor. The crater is about 34 km (20.4 mi.) across, similar to the size of the West Clearwater impact structure in Canada. The crater Golubkina is located at about 60.5 degrees north latitude, 286.7 degrees est longitude. Magellan data reveal that Golubkina has many characteristics typical of craters formed by a mereorite impact including terraced inner walls, a central peak, and radar-bright rough ejecta surrounding the crater. The extreme darkness of the crater floor indicates a smooth surface, perhaps formed by the ponding of lava flows in the crater floor as seen in may lunar impact craters. The radar-bright ejecta surrounding the crater indicates a relatively fresh or young crater. Craters with centeral peaks in the Soviet data range in size from about 10-60 km (6-36 mi.) across. The largest crater identifed in the Soviet Venera data is 140 km (84 mi) in diameter. This Magellan image strip in approx. 100 km (62 mi.) long. The image is a mosaic of two orbits obtained in the first Magellan radar test and played back to Earth to the Deep Space Network stations near Goldstone, CA and Canberra, Australia, respectively. The resolution of this image is approximately 120 meters (400 feet). The see-saw margins result from the offset of individual radar frames obtained along the orbit. The spacecraft moved from the north (top) to the south, looking to the left.

On February 21, 1972, Luna 20 soft landed in the rugged highlands between Mare Fecunditatis and Mare Crisium. The Luna 20 descent stage still sits silently on the Moon, clearly visible in this image taken by NASA Lunar Reconnaissance Orbiter.

This image is a mosaic of 24 orbits of the Navka region of Venus. The image is centered at about 10 degrees south latitude and 335 degrees east longitude. The image is about 400 km (240 miles) across. 'Behepa 8' marks the approximate landing site of the Soviet Venera 8 lander, which took measurements at the surface of Venus in 1972. The Venera 8 lander measured granitic or continental-like materials at the landing site. Magellan data reveals the landing site to lie in a region of plains cut by tectonic ridges and troughs. Volcanic domes and flows are seen throughout the region. Studying the regional setting of the Venera landing sites is important in linking information about surface composition to surface morphology seen in radar images. Resolution of the Magellan data is about 120 meters (400 feet). http://photojournal.jpl.nasa.gov/catalog/PIA00460
