Amerykański satelita obserwacji Ziemi Landsat 8 obserwuje już naszą planetę od 10 lat:
Pięć lat Landsata 8 BY KRZYSZTOF KANAWKA ON 8 MARCA 2018
Zdjęcie wulkanu na Kamczatce okiem Landsata 8 (9-10 stycznia 2018) / Credits - NASA, USGSW lutym tego roku minęło pięć lat od początku misji Landsat 8.
Start misji Landsat 8 nastąpił 11 lutego 2013 roku. Satelita został wyniesiony na orbitę heliosynchroniczną o wysokości około 700 km za pomocą rakiety Atlas 5.
Satelita Landsat-8 ma masę 2071 kg i wymiary 3×2,4 metra. Gdy ten satelita zostanie umieszczony na orbicie, zostanie rozłożony pojedynczy panel wyposażony w baterie słoneczne o łącznej długości 9 metrów. Landsat-8 jest wyposażony w dwa podstawowe sensory – Operational Land Imager (OLI), pracujący na dziewięciu różnych zakresach fal oraz Thermal Infrared Sensor (TIRS) pracujący na kolejnych dwóch zakresach fal. Misja tego satelity została przewidziana na przynajmniej 5 lat.
Pięć lat po starcie satelita Landsat 8 nadal funkcjonuje prawidłowo. Satelita wykonał ponad 26 tysięcy okrążeń wokół Ziemi i przesłał ponad 1,1 miliona obrazów naszej planety. Stanowi to 16% całego archiwum satelitów Landsat, które obserwują Ziemię łącznie 45 lat.

(...) Landsat 8, which before launch was called the Landsat Data Continuity Mission, launched into orbit on Feb. 11, 2013. Once it became operational and was renamed Landsat 8, the satellite continued a streak of engineering and science success unmatched in spaceflight: the succession of Landsat satellites has now made 45-plus years of continuous observations of Earth's surface, without any gaps.
The length of this record is what makes Landsat a "cornerstone" program in the growing field of land imaging. For scientists that want to compare new imagery or data to previous decades, the unbroken Landsat record offers the one, consistent reference point. This role is furthered by USGS’s and NASA's commitment to keeping the entire Landsat data archive free and accessible to scientists and the public. Landsat 9 is targeting a launch in 2020 and will continue that role. (...)

VANDENBERG AFB, Calif. -- Roaring off the launch pad to build upon a 40-year legacy of monitoring the Earth's environment from space, the latest and greatest satellite carrying the name Landsat successfully arrived in orbit Monday.

See full photo gallery "I do not think it hyperbole to suggest that all seven billion of us will benefit from the results of the Landsat Data Continuity Mission," said Jim Irons, the satellite's project scientist. (...)
NASA was responsible for buying the satellite, the instruments and the Atlas 5 rocket, performing overall systems engineering and controlling early orbit operations. The U.S. Geological Survey will take control of the spacecraft once it is commissioned and will be responsible for mission operations, data processing and archiving. (...)
The Landsat era took flight in 1972, beginning an uninterrupted, unparalleled record of the planet's surface and its changes from urban expansion, deforestation and natural disasters that scientists can mine for long-term and broad-scale studies and applications.
"We're not just taking pretty pictures, we are collecting data where we measure how much energy is reflected or emitted at these different wave-lengths, quantitatively. We do that in order to ensure we understand change when it occurs and what we're looking at and making consistant measurements," said Irons.
Carrying two instruments -- the Operational Land Imager built by Ball Aerospace and the Thermal Infrared Sensor built in-house at NASA's Goddard Space Flight Center -- the satellite will image 115-mile-wide swaths of Earth and repeat the same ground track every 16 days or about every 224 orbits.

Artist's concept of the Landsat 8 satellite NASA launched in February 2013. Credit: Orbital ATKThe successful launch Feb. 11 of the Landsat 8 Earth observation satellite brought sighs of relief from a user community that has been making due with degraded data from a spacecraft that, thankfully, has continued operating well beyond its life expectancy. Unfortunately, for those seeking long-term stability in a program that since 1972 has facilitated applications ranging from water- and energy-resource management to environmental-change studies, there’s no relief in sight.
