Satelayiti ya Copernicus Sentinel-6 yakhazikitsidwa kuti iwone momwe nyanja ilili

Ndi SpaceX Falcon 9 yomwe ikumaliza bwino kukhazikitsidwa, satellite yatsopanoyi - yaposachedwa pamasatayiti angapo opangidwa limodzi ndi Europe ndi USA - cholinga chake ndikutsata kukwera kwa nyanja pogwiritsa ntchito ukadaulo waposachedwa kwambiri wa ma radar altimetry.

Malinga ndi European Space Agency, kuyeza kumeneku ndikofunikira pa sayansi ya nyengo komanso kupanga mfundo.

Nyamukani

Ponyamula satelayiti ya Sentinel-6 ya 1.2, rocket ya Falcon 9 idanyamuka ku Vandenberg Air Force Base ku California pa 21 Novembala.

Satelayiti idatumizidwa mozungulira pasanathe ola limodzi kuchokera pomwe liftoff idalumikizana ndikukhazikika pamalo oyambira ku Alaska.

Miyeso yapanyanja

Mtsogoleri wa ESA wa Earth Observation Programs, a Josef Aschbacher, adati:

“Ndine wonyadira kwambiri kuwona kuti Copernicus Sentinel-6 ikukwera usiku uno ndikudziwa kuti ili paulendo wopita kukayamba ntchito yake yopitiliza muyeso wamadzi omwe akufunikira kuti amvetsetse ndikuwunika zovuta zomwe zikukwera kunyanja. ”

"Sindikufuna kungothokoza magulu a ESA omwe agwira ntchito molimbika kuti afike pano, komanso a EC, Eumetsat, NASA, NOAA ndi CNES, ndipo, zowonadi, tikuyembekezera kupitilizabe mgwirizano pakati pawo mabungwe athu osiyanasiyana. ”

Kutalika kwa nyanja kunayamba mu 1992 ndipo Copernicus Sentinel-6 Michael Freilich cholinga chake posachedwa chidzatenga ndodo ndikuwonjezera deti iyi yolowera kunyanja.

Ntchitoyi ili ndi ma satelayiti awiri ofanana omwe adakhazikitsidwa motsatizana, atero ESA, chifukwa chake mzaka zisanu, Copernicus Sentinel-6B ikhazikitsidwa kuti itenge. Ntchito yonseyi idzaonetsetsa kuti deta ikupitilira mpaka 2030, akutero.

Ma Altimeter ndi ma radiometers

Satelayiti iliyonse imakhala ndi altimeter ya radar, yomwe imagwira ntchito poyesa nthawi yomwe zimatengera kuti ma radar amayenda padziko lapansi ndikubwerera ku satellite. Kuphatikizidwa ndi deta yolondola ya satelayiti, kuyeza kwa ma altimetry kumapangitsa kutalika kwa nyanja.

Phukusi la zida za satelayiti mulinso ndi radiometer yayikulu yama microwave yomwe imathandizira kuchuluka kwa nthunzi yamadzi mumlengalenga, yomwe imakhudza kuthamanga kwa ma radar a ma altimeter.

Mutha kuwerenga zambiri patsamba la ESA.
