STS096-705-9
Cape Sinop, Black Sea Coast of Turkey: Cape Sinop is the prominent cape. Spring meltwater entering the Black Sea during the STS-96 mission probably explains the rich sediment load (light blue) visible offshore. Sediment from the Kizil Irmak River (just outside the view to the east) makes an eddy in the coastal current visible. The ancient and modern city of Sinope lies at the narrow point of the prominent peninsula. Tourist hotels abound along the scenic north coast of Turkey. The cynic phoilosopher Diogenes was born in Sinope about 320 BC.

Strait of Dover: Dover in southeast England lies on the right under thicker cloud. Calais, France, a larger city, is more visible on the left. Individual seacraft and their wakes (linear white flecks) occupy the line between the cities. The line of wakes also marks the location of the undersea Channel Tunnel, known as the "Chunnel." The treacherous Goodwin Sands appear as lighter blue signatures just north of Dover.

Low Sun Angle on a Line of Thunderstorms: The "anvil" cloud of a large storm hundreds of miles off track (far right) is apparent in this very oblique, low- sun view. Three dimensional views such as this are difficult to acquire from low earth orbit.

Lakes of the Italian Alps: The slopes of the Alps are forested and appear green, whereas the valley floor appears generally gray due to its dense urban landscapes (lower left). The valley and all the lakes in the view have been carved by a succession of glacier advances during the ice ages of the past 2 million years. The largest lake (center) is Lake Maggiore, ringed by the snowcapped Alps in Switzerland (right side and top of the view). Some of the highest peaks reach almost 3000m (midway down the right side of the view). The major transalpine St. Gotthard railway, joining Milan and Zurich, enters the view along the largest valley (Valle Levantina, right-which becomes Lake Maggiore). The next lake east is smaller Lake Lugano. "A great stone dam ... built ... to carry the railway" can be seen crossing L. Lugano. Lake Como appears at the bottom of the view. The railroad passes through the town of Como at the downstream end of Lake Como before heading southeast across the valley floor to Milan (just outside the bottom-left corner of the view). The large regional Malpensa Airport appears lower left.

Chalcidice Peninsula, Northern Greece (Macedonia): Chalcidice peninsula itself has three promontories known as (left to right), Kassandra, Sithonia and Aktí, which appear prominently from low earth orbit. The 30-mile long eastern promontory of Aktí (right) is renowned in Greece as a center of twenty Orthodox Christian monasteries, classed under the constitution as semiautonomous communities. The monasteries lie along the coast at the foot of famous Mt. Athos (also known as the Holy Mountain) which appears as the devegetated high point near the tip of the promontory. In his "massive invasion" of Greece in 480 BC, Persian King Xerxes I excavated a canal at the narrow (1.5 mi. wide) base of the Aktí "finger" to avoid leading his fleet around the dangerous seas on the tip of the finger. The now-filled remains of the canal can be seen in this view.

Onekotan Island, Kuril chain, Sakhalin Oblast, Russian Far East: The Kuril island chain is a line of volcanoes connecting northern Japan (Hokkaido) with the Kamchatkan peninsula, and separating the Pacific plate from the Eurasian plate. Onekotan (35 mi. long) is one of the northernmost of the Kurils, seen here under a dusting of snow, with the large southern caldera at the big end of the island clearly visible. The caldera contains a lake, seen here largely ice-free, with a new central volcanic dome projecting through the lake. The small island immediately south is Kharimkotan I.

Lake Baykal, and Baykal rift, Russia: Lake Baykal, the largest freshwater lake in the world (30,500 sq km in area; 1741 m deep), stretches beneath the International Space Station in this westward view. At the southwest end of the lake, the university city of Irkutsk occupies the end of a narrow bay on the northern coast. Academician Ridge extends northeastward into the lake.

The lake fills most of the Baykal rift which, like the Rio Grande rift of southwestern North America, began opening about 28 million years ago; some segments are still active. Hot springs rise and enter the lake along the faults that bound Academician Ridge, and million-year-old volcanic vents (Tunka, Khamar Daban) have constructed the highlands at the southwest end of the rift.

Sinai Peninsula, Dead Sea and Eastern Mediterranean Sea: The Sinai Peninsula of Egypt is centered in this southwestward view; the Red Sea, Gulf of Suez, Suez Canal, and Nile River delta lie beyond. Bahrat Hims, Syria, is the pale blue lake near the center on one end. The Gulf of Aqaba, Dead Sea, and the Sea of Galilee define the eastern margin of the Peninsula. The city of Haifa is on the peninsula directly west of the Sea of Galilee; Beirut, Lebanon occupies the next prominent peninsula to the north.

The Dead Sea fault zone marks the boundary between the African and Arabian tectonic plates; Sinai Peninsula is the northeastern tip of the African plate, which is being pulled apart by the Red Sea rift. This is one of the best photos to date of the region where the Dead Sea fault zone splays to the northeast in Syria. Those northeasterly faults and the East Anatolian fault zone define the margin between the Arabian and Eurasian plates.

Southern Tip of Sinai Peninsula, Egypt: Madiq Gubal, the strait between the Egyptian mainland and Ras Muhammad on the southern tip of the Sinai Peninsula, is just above center of this southwestward view. The islands of Tiran and Sinafir are at left center. The islands and fringing coral reefs mark the edges of fault blocks, which have the same orientations as the faults onshore - for example, the straight, sharp contact between the darker bedrock of the Sinai Peninsula and the paler coastal sands.

Gebel Musa or Mt. Sinai (2285 m), with the monastery of St. Catherine on the northern flank, is within the dark oblong area in the midst of the bedrock shield. Tan and rust-colored sedimentary rocks contrast with the brown Precambrian igneous basement rocks; lighter oval bodies within the shield are granite masses.

Lake Ontario: Lake Ontario, the smallest of the Great Lakes, as it appeared to the STS-96 crew in low light and partial sunglint. Lake Ontario discharges into the Saint Lawrence river which flows northeast towards the Atlantic. Lake Champlain also shows partial sunglint east-northeast of Lake Ontario. The thin white lines in the photograph are contrails from some of the heavy air traffic in this eastern corridor.
