Zimaliza kuti magulu akulu akulu am'mlengalenga otsika adzasinthiratu zakuthambo zamagetsi zowoneka bwino komanso zowonera ndipo zitha kukhudza mawonekedwe a thambo lausiku kwa oyang'anira nyenyezi padziko lonse lapansi.
Ripotilo - Mphamvu yamagulu a satellite pa zakuthambo zakuthambo ndi malingaliro pakuchepetsa - ndi zotsatira za msonkhano waposachedwa wa SATCON1 wophatikiza asayansi 250, mainjiniya, ogwiritsa ntchito satelayiti, ndi ena onse. NOIRLab imayimira National Optical-Infrared Astronomy Research Laboratory, likulu ladziko lonse la US la zakuthambo zowonera usiku ndi infrared.
Ripotilo likumaliza kuti zotsatira za magulu akulu akulu amlengalenga pa kafukufuku wakuthambo komanso pazochitika zaumunthu zakumwamba usiku zimachokera "mopepuka" mpaka "mopambanitsa".
Makamaka, lipotilo limapereka zotsatira ziwiri zazikulu. Choyamba, kuti LEOsats imakhudza kwambiri mapulogalamu asayansi omwe amafunikira kuwunika kwamadzulo, monga kusaka ma asteroid owopsa Padziko lapansi ndi ma comets.
"Madzulo dzuwa limakhala lili m'munsi mwa owonera pansi, koma osati ma satelayiti pamtunda wa makilomita mazana ambiri, omwe akuunikirabe. Malingana ngati ma satelayiti amakhalabe pansi pamakilomita 600 (osati ma 400 mamailosi), kusokonekera kwawo pakuwona zakuthambo kumakhala kocheperako nthawi yakuda kwambiri usiku. Koma ma satelayiti okwera kwambiri, monga gulu la nyenyezi lomwe OneWeb lomwe limazungulira pamakilomita 1,200 (750 miles), amatha kuwonekera usiku wonse nthawi yachilimwe komanso nthawi yayitali usiku munthawi zina. Magulu a nyenyezi amenewa atha kukhala ndi zotsatirapo zoyipa kwambiri pamapulogalamu ambiri ofufuza kumaofesi oyang'anira malo oyang'anira padziko lapansi. Kutengera kutalika kwake ndi kuwala kwake, ma satellite a nyenyezi amathanso kuwononga usiku wokhala ndi nyenyezi zakuthambo, okhulupirira nyenyezi, komanso okonda zachilengedwe ena. ”
Kupeza kwachiwiri kwa lipotili ndikuti pali njira zosachepera zisanu ndi chimodzi zochepetsera zovuta ku zakuthambo kuchokera kumagulu akulu amlengalenga:
- Yambitsani ma LEOsats ochepa kapena ayi. Iyi ndiye njira yokhayo yomwe ingakwaniritse zakuthambo.
- Ikani satelayiti kumtunda wazitali osapitilira ~ 600 km.
- Mdima wa satelayiti kapena mugwiritse ntchito mthunzi wa dzuwa kuti muphimbe mawonekedwe awo owonekera.
- Sungani mawonekedwe amtundu uliwonse wa satelayiti mumlengalenga kuti muwonetse kuwala kochepa ku Earth.
- Chepetsani kapena pamapeto pake mutha kuthetsa mayendedwe amtundu wa satellite mukamajambula zithunzi zakuthambo.
- Pangani chidziwitso cholongosoka cha satellites kuti owonerera apewe kuwalozetsa ma telescope.
Mutha kutsitsa lipotilo patsamba la noirlab.edu.
Mu Juni, SpaceX idakhazikitsa ma satelayiti ena 60 a Starlink ndipo adawonetsa, kwa nthawi yoyamba, chowonera chododometsa cholepheretsa kuwala kwa dzuwa kugunda malo owala kwambiri a chombo. Izi zinali poyankha madandaulo okhudzana ndi kuipitsa pang'ono komwe kudakwezedwa kale.
Onaninso: Maganizo: Chifukwa chiyani mgwirizano wapansi ndikofunikira kwa magulu a satellite a LEO kumwamba
