\nA cloud-specked view of the US territory of Guam in the western Pacific Ocean, as seen by ESA\u2019s Proba-1 microsatellite, which is still observing Earth despite being launched 16 years ago.\n<\/p>\n

\nAntonio B. Won Pat International Airport is visible just right of centre. To the north is the town of Tamuning and the bluish, coral-rich shores of Tumon Bay, with the capital Hag\u00e5t\u00f1a to the west.\n<\/p>\n

\nThe cubic-metre Proba-1<\/a> was 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 as the Agency\u2019s longest-serving Earth-observing mission<\/a>.\n<\/p>\n

\nProba-1\u2019s main hyperspectral CHRIS imager acquires 13 square km scenes at 17 m spatial resolution across 18 programmable visible and near-infrared wavelengths. Proba-1 additionally carries a 5 m-resolution black and white camera. The microsatellite\u2019s agile nature means it can image the same scene from a variety of viewing angles.\n<\/p>\n

\nOnboard 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

\nFor more background on Proba-1, read this celebration in the ESA Bulletin<\/i><\/a>.\n<\/p>\n

\nProba-1 led the way for the Sun-monitoring Proba-2<\/a> in 2009, the vegetation-tracking Proba-V<\/a> in 2013 and the Proba-3<\/a> precise formation-flying mission planned for late 2020.\n<\/p>\n
