Belgrade, Republic of Serbia (NASA, International Space Station, 03/05/13)

Image by NASA's Marshall Space Flight Center
One of the Expedition 34 crew members aboard the Earth-orbiting International Space Station captured this image of Belgrade, the capital city of the Republic of Serbia. Located at the confluence of the Danube and Sava Rivers, the Belgrade metropolitan area has a population of 1.65 million (2011 census information) which ranks it as one of the largest such areas in southeastern Europe. Human occupation of the Belgrade area can be traced back over 6000 years. According to historical reports, a city that eventually became Belgrade existed by at least 279 BC. The core of old Belgrade -- known as Kalemegdan --is located along the right banks of both the Danube and the Sava Rivers (image center). To the west across the Sava, Novi Beograd (New Belgrade) was constructed following World War II. The photograph was acquired on March 5, 2013 with a digital camera using the equivalent of a 700 millimeter lens.

Southwestern Wildfires (NASA, International Space Station, 06/02/12)

Image by NASA's Marshall Space Flight Center
Downlinked from the International Space Station this still image --- part of a series from a mounted, automated, twilight session -- when viewed in sequence shows the flame ring associated with wild fires in the Southwest move from bottom to top-center framed at a distance by the bright urban areas of Tucson, Phoenix, El Paso-Las Cruces, and finally Albuquerque (mostly under cloud).

Lake Fitri, Chad (NASA, International Space Station, 01/19/12)

Image by NASA's Marshall Space Flight Center
Lake Fitri, Chad is featured in this image photographed by an Expedition 30 crew member on the International Space Station. Lake Fitri is an endorheic, or terminal lake in a desert basin in the southern Sahara Desert. Muddy yellow-brown water marks the center of the depression (center), with a ring of dark brown muds and burnt vegetation on the exposed lake floor to the north. The lake shoreline supports a thin line of reed and floating grass vegetation which appears as dark green in the image. Deserts have so little rainfall that many rivers cannot reach the sea, but end at local low points where they form lakes. Here the usually dry Wadi Batha empties into Lake Fitri. Over time, water flow in Wadi Batha has created a large delta, which occupies the entire top left third of the image—a sense of scale is given by the 23--kilometer length of the lake. The lake has been designated under the Ramsar Convention as a wetland of international importance. Other features visible in the image reveal evidence of significant climate change. The dry part of the present lake shows that the lake has been larger in the last several decades. But, as NASA scientists point out, the lake was once many times larger than its present surface area, as shown by numerous sweeping curves of ancient beaches which are now situated many kilometers from the present shoreline, at higher altitudes (upper right). Inland lakes are highly sensitive to the exact equilibrium between the amount of inflow from contributing rivers like Wadi Batha and evaporation. Each beach ridge therefore shows a different lake level and thus a different balance in the lake-river-climate system. A smaller river enters from the south (top right) and cuts through the beach reaches on its way to the lake. The irregular, elongated, tan patches to the west of the lake are linear dunes aligned parallel to the dominant winds which blow from the northeast. The dunes have all formed on the downwind side (southwest) side of the lake since the lake bed and delta provide the sands which have built the dunes. The dunes indicate that during past climatic phases the lake has been almost or completely dry on repeated occasions—often enough for these great dunes, many kilometers long and several meters high, to form even in the lowest parts of the lake. The islands visible in the center of the lake are likewise remnants of dunes. These dunes are smaller than those on the lake margin, presumably because waves from the lake have eroded them. Villages occupy the points of some major dunes, and some islands, where fishermen can gain easy access to the lake.
