ICESat-2 (original) (raw)
ICESat-2 (Ice, Cloud, dan tanah Elevation Satelit 2), bagian dari Earth Observing System NASA, adalah sebuah misi satelit yang direncanakan untuk mengukur lapisan es elevasi massa, es laut freeboard serta karakteristik topografi lahan dan vegetasi. ICESat-2 adalah rencana tindakan untuk misi ICESat. Ini akan diluncurkan pada tahun 2016 dari Vandenberg Air Force Base di California di orbit kutub melingkar dengan ketinggian sekitar 496 km. Hal ini sedang dirancang untuk beroperasi selama 3 tahun, dan akan membawa cukup propelan selama 7 tahun.

| dbo:abstract | ICESat-2 ist ein Projekt des Goddard Space Flight Centers der NASA und Nachfolger des Erdbeobachtungssatelliten ICESat. Im August 2011 wurde Orbital ATK mit der Entwicklung und dem Bau des Satelliten beauftragt. Er ist mit einem Lidar-System ausgerüstet, das sechs Strahlen mit grünem Laserlicht verwendet, um das Höhenprofil der polaren Eiskappen zu vermessen. Der Start des Satelliten erfolgte am 15. September 2018 mit der letzten Delta II; er befindet sich seit dem 7. Dezember 2018 im operativen Betrieb. Zwischenzeitlich, nach dem Ausfall von ICESat 2009, hatte die NASA mit der Operation IceBridge Flugzeuge zur Überwachung des Polareises eingesetzt. (de) ICESat-2 (Ice, Cloud, and land Elevation Satellite 2), part of NASA's Earth Observing System, is a satellite mission for measuring ice sheet elevation and sea ice thickness, as well as land topography, vegetation characteristics, and clouds. ICESat-2, a follow-on to the ICESat mission, was launched on 15 September 2018 onboard Delta II as the final flight from Vandenberg Air Force Base in California, into a near-circular, near-polar orbit with an altitude of approximately 496 km (308 mi). It was designed to operate for three years and carry enough propellant for seven years. The satellite orbits Earth at a speed of 6.9 kilometers per second (4.3 mi/s). The ICESat-2 mission is designed to provide elevation data needed to determine ice sheet mass balance as well as vegetation canopy information. It will provide topography measurements of cities, lakes and reservoirs, oceans and land surfaces around the globe, in addition to the polar-specific coverage. ICESat-2 also has the ability to detect seafloor topography up to 100 feet (30m) below the surface in clear watered coastal areas. Because the great changes of polar ice cover in global warming are not quantified, one of the main purposes of ICESat-2 is measuring the changing of the elevation of ice sheets by its laser system and lidar to quantify the influence of melting ice sheet in sea-level raising. Additionally, the high accuracy of multiple pulses allows collecting measurement of the heights of sea ice to analyze its change rate during the time. The ICESat-2 spacecraft was built and tested by Northrop Grumman Innovation Systems in Gilbert, Arizona, while the on board instrument, ATLAS, was built and managed by Goddard Space Flight Center in Greenbelt, Maryland. The ATLAS instrument was designed and built by the center, and the bus was built by and integrated with the instrument by Orbital Sciences (later Orbital ATK). The satellite was launched on a Delta II rocket provided by United Launch Alliance. This was the last launch of the Delta II rocket.

ICESat-2 (Ice, Cloud, and land Elevation Satellite c'est-à-dire satellite glace, nuage et altitude terrestre-2) est une mission spatiale du programme d'observation de la Terre de la NASA qui est mise en orbite le 15 septembre 2018 par le dernier exemplaire du lanceur Delta II. Ce satellite d'observation de la Terre de l'agence spatiale américaine prend la suite de ICESat dont la mission s'achève en octobre 2009 et doit comme ce dernier fournir des informations détaillées sur la fonte des glaciers au niveau des pôles et l'élévation du niveau des mers. Cette mission s'inscrit dans le cadre des études sur le changement climatique. L'altimètre laser embarqué par le satellite doit permettre de mesurer avec une grande précision les variations de niveau de la banquise, des glaciers et du niveau des mers. Le satellite, qui circule sur une orbite polaire (inclinaison orbitale de 92,0°) à une altitude de 496 km, doit fonctionner durant au minimum 3 ans.

O ICESat-2, uma continuação da missão ICESat, que foi lançada em 15 de setembro de 2018 da Base Aérea de Vandenberg, na Califórnia, Estados Unidos,em uma órbita quase circular, quase polar, com uma altitude de aproximadamente 496 km. Ele foi projetado para operar por três anos e transportar propelente suficiente por sete anos. O projeto ICESat-2 está sendo gerenciado pelo Goddard Space Flight Center em Greenbelt, Maryland. O único instrumento está sendo projetado e construído pelo centro e o ônibus foi fornecido pela Orbital ATK. O satélite foi lançado no foguete Delta II fornecido pela United Launch Alliance. Este foi o último lançamento do veículo Delta II (pt) |
