* 우주에서 본 지구의 가장 아름다운 모습 공개 *   김은정 기자 이메일icdi@chosun.com      북극의 모습 유럽우주국(ESA)이 환경 관찰 위성인 ‘엔비샛(Envisat)’ 발사 10주년을 맞아 앤비샛이 촬영한 가장 아름다운 지구의 사진 18점을 공개했다.   ‘태풍의 눈’에 휩싸인 대륙의 모습, 화산, 말라있는 강줄기의 모습 등을 담았다. 앤비샛은 지난 2002년 유럽우주국이 발사한 위성으로 매일 지구 궤도를 14바퀴씩 돌면서 기후변화와 환경오염을 정밀 관측한다. 당초 5년간만 사용할 계획이었지만 지금까지도 임무를 수행하고 있다.      사하라 사막          태풍의 눈

This image was acquired by Envisat's Medium Resolution Imaging Spectrometer (MERIS) instrument on 21 March 2009, working in Full Resolution mode to provide a spatial resolution of 300 m.

Galapagos’s largest island is Isabela (visible). The five volcanoes seen on the island are (from north to south): Wolf Volcano, Darwin Volcano, Alcedo Volcano, Sierra Negra Volcano and Cerro Azul Volcano. The bigger island to the right of Isabela is Santiago Island. The image was obtained by combining three Advanced Synthetic Aperture Radar (ASAR) acquisitions (23 March 2006, 14 August 2008 and 1 January 2009) taken over the same area. The colours in the image result from variations in the surface that occurred between acquisitions. Apart from mapping changes on the land surface, radar data can also be used to determine sea surface parameters like wind speed, wind direction and wave height. Different wave types and wind speeds are visible in the image as ripples on the water surface.

This image was acquired by Korea’s Kompsat-2 on 27 June 2007. ESA is supporting Kompsat-2 as a so-called 'Third Party Mission', which means ESA utilises its multi-mission European ground infrastructure to acquire, process and distribute data from the satellite to its wide scientific user community.

ALOS is supported by ESA as a 'Third Party Mission', which means that data and imagery are distributed under a cooperative agreement between the Agency and the Japan Aerospace Exploration Agency (JAXA).

A major benefit of this long dataset is the ability to identify gradual changes occurring on the Earth's surface. Twenty years separate these two Landsat Thematic Mapper (TM) images of Instanbul, the largest city in Turkey and the administrative capital of the Province of Istanbul. Until 1930 Istanbul was commonly known by its original Greek name Constantinople, and in Classical Antiquity as Byzantium or Byzantion. Today, with a population of between 11 and 15 million people, Istanbul is the most populated city of Turkey and is considered by some to be one of the largest cities in Europe. The old part of the city, which corresponds to ancient Constantinople, is mainly located on the south west corner of the Bosporus strait. However, the modern city is much larger and covers both the European and Asian sides of the Bosporus. The strait separates Europe from Asia and the Black Sea from the Marmara Sea. Two bridges cross the strait: the first, Bogazici (Bosporus I) bridge, was buit in 1973 and is visible only in the first image; the second, Fatih Sultan Mehmed (Bosporus II) bridge, was completed in 1988 about five kilometres north of Bosporus I. The comparison between the 1984 image on the left and the 2004 image on the right suggests that Istanbul has not undergone a substantial growth in the last 20 years. Most of changes have affected the western areas of the city. Here, the Atatürk International Airport, visible as the bright area by the coast of the Marmara Sea, on the centre left of both images, grew considerably from 1984 to 2004. Istanbul lies in one of the most seismic areas of the planet. The North Anatolian Fault, the most active fault system in Turkey, runs about 40 kilometres to the southeast of the city. one of the strongest (7.4 on the Richter scale) and most recent seismic event associated to this fault array is the Marmara earthquake. It occurred on August 17 1999 at 3:00 am (local time) and caused the death of more than 17,000 people. 44,000 were injured and damage to Turkey's industrial heartland was extensive.

The Project for on-Board Autonomy (Proba) is a technology demonstration mission of the European Space Agency. CHRIS is a push-broom spectrometer capable of imaging up to 200 spectral bands in the visible range. Together with the scanning and manoeuvring capabilities of the spacecraft it supports Bidirectional Reflectance Distribution Function (BRDF) measurements used in land, sea and atmospheric observations.
