"Ua Satellite" Pohihihi: Ua nalowale ma mua o 500 mau Satellites Starlink LEO i ka hana a ka lā

Ka Hanana: Mai nā Pohō Kakaikahi a i ka Ua Nui

ʻAʻole i hana koke ʻia ka hoʻoneʻe nui ʻana o nā satelite LEO o Starlink. Mai ka hoʻomaka mua ʻana o ka papahana i ka makahiki 2019, ua liʻiliʻi loa nā pohō o nā satelite i ka wā mua (2 i ka makahiki 2020), e like me nā helu attrition i manaʻo ʻia. Eia nō naʻe, ua ʻike ʻia ka piʻi nui ʻana o ka makahiki 2021 (78 pohō), ukali ʻia e nā pae kiʻekiʻe mau (99 i ka makahiki 2022, 88 i ka makahiki 2023). Ua piʻi ka pilikia i ka makahiki 2024 me 316 mau satelite e ʻā ana—ʻekolu helu o nā makahiki i hala—e hōʻuluʻulu ʻia ana he 583 mau pohō, e like me ~1 satelite i nalowale i kēlā me kēia lā a i ʻole 1 i loko o 15 i hiki ʻole ke hoʻopau i kāna misionari.

Hana Lā: ​​ʻO ke kanaka hewa i ʻike ʻole ʻia

Ua hōʻoia ka noiʻi NASA i kahi pilina pololei ma waena o ka deorbiting satellite a me nā pōʻaiapuni lā. Ua kūlike ka hoʻokuʻu ʻana o 2019 me ka palena iki o ka lā, akā i ka hoʻonui ʻia ʻana o ka hana o ka lā, ua piʻi ka huki lewa ma nā orbits 340-550km ma >50% i ka wā o nā ʻino geomagnetic. Hana ʻia kēia i ka wā:

1. Hoʻokuʻu ʻia ka Honua e nā lapalapa lā i hoʻoulu ʻia e ka Sunspot/coronal mass ejections
2. Hoʻomehana nā ʻino geomagnetic a hoʻonui i ka lewa luna
3. Hoʻonui ka lewa i hoʻonui ʻia i ka huki ʻana, e hoʻoulu ai i ka palaho orbital

Paradox: Hōʻike nā ʻino nāwaliwali i ka make

ʻAʻole like me nā mea i manaʻo ʻia, ua loaʻa he 70% o nā pohō i ka wā o nā ʻino geomagnetic waena/nāwaliwali. ʻO kēia mau hanana lōʻihi (nā lā/pule mau) e hoʻohaʻahaʻa mālie i nā orbits ma mua o ka hoʻōla ʻana, ʻaʻole e like me nā ʻino ikaika akā pōkole. He laʻana koʻikoʻi: 40 o 49 mau satelite Starlink i hoʻokuʻu ʻia i Pepeluali 2022 i hāʻule i nā ʻino nāwaliwali mau.

Nā Kūʻai Kūʻai Haʻahaʻa-Orbit

ʻOiai ʻo nā kaʻapuni 550km o Starlink e hiki ai i nā kamaʻilio latency haʻahaʻa, ʻo ko lākou kokoke ʻana i ka Honua:

1. Hoʻopaʻa i ke ola hana i ~5 mau makahiki (e kūʻē i ka 400km o ka ISS o ke kaʻapuni)
2. Hoʻonui i nā hopena kauō i ka wā o ka solar maxima
3. Hoʻoweliweli nui i nā satelite hoʻāʻo ma 210km kiʻekiʻe

Nā Pilikia o ka Wā e Hiki Mai Ana

Me nā satelite Starlink ma mua o 6,000 e hoʻopuni ana i ka wā o ka nui o ka lā—he hui pū ʻana o ka mōʻaukala—ua ʻōlelo aku nā kānaka ʻepekema:

1. Hoʻolalelale ʻia ka emi ʻana o ka satelite
2. ʻO ka hiki ke hoʻemi ʻia ka ozone mai nā hoʻokuʻu ʻana o ka alumini oxide i ka wā e hoʻi hou ai ʻo SpaceX e hōʻemi i nā pohō ma o ka hoʻokuʻu wikiwiki ʻana i ka hoʻopiha hou ʻana a me nā protocol deorbit automated, akā ʻo ke kūpaʻa o ke kaʻina hana o ka lā he mea nui ia no ka ʻoihana holoʻokoʻa.

Hopena

Hōʻike kēia hanana i ke kūlana koʻikoʻi o ke kūlohelohe ma luna o ka ʻenehana kanaka a hōʻike i ka pono no nā hoʻolālā ʻōnaehana LEO e wehewehe ana i nā mana o ka lā cyclical.

ʻO Chengdu Concept Microwave Technology CO., Ltd kahi mea hana ʻoihana o nā ʻāpana RF 5G/6G no ke kamaʻilio ukali ma Kina, me ka kānana RF lowpass, kānana highpass, kānana bandpass, kānana notch/band stop, duplexer, Power divider a me directional coupler. Hiki ke hoʻopilikino ʻia lākou āpau e like me kāu mau koi.
