Radio ʻo ka alapine ma muli o ka hohonu makahiki Kūleʻa ka kamaʻilio ʻana ma muli o ka haʻahaʻa bandwidth a me ka hoʻonui ʻana i ka pono o ka nui o ka lawe ʻana i ka ʻikepili kiʻekiʻe. Hiki i ka ʻōnaehana laser a i ʻole optical ke uhaki i nā kaohi kamaʻilio. NASA ua hoʻāʻo i nā kamaʻilio laser e kūʻē i kahi mamao loa a hōʻike i nā kamaʻilio bandwidth kiʻekiʻe i ka hohonu makahiki i ka wā i hoʻomālamalama mai ai i ka Honua i kahi wikiō ultra-high-definition ma o ka laser mai kahi mamao o 32 miliona km, mai Psyche spacecraft e hele nei ma ka hohonu. makahiki i metala-waiwai asteroid Psyche aia ma ke kāʻei asteroid ma waena Mars a me Iupita. ʻO kēia ka hōʻike mua o nā kamaʻilio optical ma waho o ka mahina. Hohonu Space Ua loaʻa ʻelua antenna Network (DSN). Radio pinepine a me nā hōʻailona laser kokoke-infrared.
Deep makahiki Hoʻohana ʻia ke kamaʻilio me ka hoʻohana ʻana i nā alapine lekiō. Eia nō naʻe, ʻaʻole hiki ke hoʻokō i nā pono kamaʻilio o kēia manawa a me ka wā e hiki mai ana makahiki ʻāpana i ka nānā ʻana i ka bandwidth liʻiliʻi a me ka piʻi nui ʻana o ka noi no ka nui o ka lawe ʻana i ka ʻikepili kiʻekiʻe.
Ma ka ʻaoʻao ʻē aʻe, hāʻawi ka laser a i ʻole ka optical based communication i nā pōmaikaʻi he nui e pili ana i nā bandwidths nui, nā loulou helu helu kiʻekiʻe a me nā SWaP haʻahaʻa (nui, kaumaha a me ka mana). Hiki iā ia ke hoʻonui i ka helu ʻikepili 10 a 100 mau manawa o ka nui o nā ʻōnaehana lekiō maʻalahi e hoʻohana nei i kēia manawa no laila hiki ke uhaki i nā kaohi kamaʻilio. No laila, pono e holomua i nā kamaʻilio optical no ka hohonu hohonu makahiki nā kamaʻilio hiki ke hoʻokō i nā pono hoʻoili ʻikepili interplanetary e hiki mai ana.
Deep Space ʻO ka hoʻokolohua Optical Communications (DSOC) kahi uku hōʻikeʻike loea ma luna o ka mokulele Psyche e holo nei i ka hohonu. makahiki i metala-waiwai kekaha Aia ʻo Psyche ma ke kāʻei asteroid ma waena Mars a me Iupita. I Kekemapa 2023, ua hōʻike ʻo ia i nā kamaʻilio kiʻekiʻe-bandwidth i ka hohonu makahiki i ka wā i hoʻomālamalama ʻia i ka Honua i kahi wikiō ultra-high-definition ma o ka laser mai 32 miliona km ma kahi hohonu. ʻO kēia ka hōʻike mua o nā kamaʻilio optical ma waho o ka mahina.
'O ka Deep Space ʻO ka Network (DSN) kahi pūnaewele o nā mea i loaʻa ma nā wahi like ʻole o ka honua e kamaʻilio me nā mokulele mamao e ʻimi ana i ka ʻōnaehana solar. Ua loaʻa i kahi antenna hoʻokolohua o kēia pūnaewele nā lekiō a me nā hōʻailona laser mai Psyche spacecraft ma kahi hohonu. Hōʻike kēia i hiki ke hoʻololi hou ʻia nā antenna DSN e kamaʻilio nei me nā mokulele mokulele ma o nā lekiō no nā kamaʻilio laser.
