\nA view looking north to south of Egypt\u2019s famous Giza Pyramid Complex, as seen by ESA\u2019s Proba-1 minisatellite.\n<\/p>\n

\nThe smaller Pyramid of Menkaure is seen to towards the centre of the image, with the larger Pyramid of Khafre down and left of it, with the Great Pyramid of Giza \u2013 the largest and oldest of the three \u2013 below and left of that.\n<\/p>\n

\nThree smaller pyramids are adjacent to the Pyramid Menkaure. The Giza Plateau sits on the edge of Cairo, fringed by suburbs.\n<\/p>\n

\nThe cubic-metre Proba-1<\/a> is the first in ESA\u2019s series of satellites aimed at flight-testing new space technologies. It was launched on 22 October 2001 but is still going strong, having recently became the Agency\u2019s longest-serving Earth-observing mission<\/a>.\n<\/p>\n

\nProba-1\u2019s main hyperspectral CHRIS imager is supplemented by this experimental High-Resolution Camera, acquiring black and white 5 m-resolution images.\n<\/p>\n

\nOther innovations include what were then novel gallium-arsenide solar cells, the use of startrackers for gyroless attitude control, one of the first lithium-ion batteries \u2013 now the longest such item operating in orbit \u2013 and one of ESA\u2019s first ERC32 microprocessors to run Proba-1\u2019s agile computer.\n<\/p>\n
