Description:

The crew of Expedition 13 recently passed a major milestone: as of late August 2006, more than one quarter of a million images of Earth had been taken from the International Space Station. The rate at which Expedition 13 has been photographing the Earth has been record-setting, as they passed the 200,000th image mark less than two months before. The 250,000th image is an oblique view (the photograph was taken from a side angle) of the city of Christchurch, New Zealand. The oblique view provides a sense of perspective and accents topography, in contrast to nadir (directly downwards) views, such as this image of Christchurch acquired by the Landsat 7 satellite in 2001.

Snow highlights the peaks of the Banks Peninsula to the southeast of the city. The peninsula has a radically different landscape compared to the adjoining, flat Canterbury Plains, where Christchurch (gray patch to the north) is located. The Banks Peninsula is formed from the overlapping cones of the extinct Lyttelton and Akaroa volcanoes. Subsequent erosion of the cones formed the heavily dissected terrain visible in the image, and sea level rise led to the creation of several harbors around the Peninsula. Erosion continues unabated today, as evidenced by the apron of greenish blue, sediment-laden waters surrounding the Banks Peninsula.

Other interesting features in the image include the braided Waimakariri River to the north-northwest of the city, and the greenish brown waters of Lake Ellesmere at image left. The coloration of the water is due both to its shallow depth (1.4 meters on average) and its high concentrations of nitrogen and phosphorus, which fertilizes the growth of large amounts of green algae.

Astronaut photograph ISS013-E-67242 was acquired August 15, 2006, with a Kodak 760C digital camera using a 180 mm lens, and is provided by the ISS Crew Earth Observations experiment and the Image Science & Analysis Group, Johnson Space Center. The image in this article has been cropped and enhanced to improve contrast. Lens artifacts have also been removed. The International Space Station Program supports the laboratory to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet.

A short note on the above message: Chaghadr ghashangeh is in Farsi, the language of the people of Iran. It means: it’s so gorgeous

انوشه جان

با كمال افتخار روز قبل از پرتاب سايوز حامل شما در محل كارم (بانك) به همكاران
شيريني دادم
و ديروز(1385/مهرماه/01 )ساعت5/15صبح روي بام خانه خود شاهد عبور افتخارآميز-شما- دختر شايسته (امير كبير )از فراز شهر خود اصفهان بودم
از ياد نبريم ايران هميشه سرفراز شاهد اولين حكومت( جهاني) انسانيت مدار. عدالت شعار—هخامنشي بوده
و امروز بسرعت وبا اعتماد به نفس در حال سازندگي استقلال طلبانه بوده
و آغوش خود را براي عزيزاني مديرو مدبرمثل شما گشوده است

وتبریکات خالصانه ام رانثارتووهمسرمهربانت وبزرگوارت می کنم
قربانت سعیده
