Ke kū nei ke kamaʻilio ʻana ma ka lewa hohonu e pili ana i ke alapine lekiō i nā palena ma muli o ka bandwidth haʻahaʻa a me ka hoʻonui ʻana o ka pono o nā helu hoʻoili ʻikepili kiʻekiʻe. Loaʻa i ka ʻōnaehana laser a i ʻole optical ka hiki ke uhaʻi i nā palena kamaʻilio. Ua hoʻāʻo ʻo NASA i nā kamaʻilio laser e kūʻē i nā mamao loa a ua hōʻike i nā kamaʻilio bandwidth kiʻekiʻe ma ka lewa hohonu i ka wā i hoʻouna ai i ka Honua i kahi wikiō wehewehe kiʻekiʻe loa ma o ka laser mai kahi mamao o 32 miliona km, mai ka mokulele Psyche e hele nei ma ka lewa hohonu i ka asteroid waiwai metala ʻo Psyche aia ma ke kāʻei asteroid ma waena o Mars a me Jupiter. ʻO kēia ka hōʻike mua o nā kamaʻilio optical ma ʻō aku o ka Mahina. Ua loaʻa i ka antenna Deep Space Network (DSN) nā hōʻailona laser alapine lekiō a me nā hōʻailona laser kokoke-infrared.
Hoʻohana nui ʻia ke kamaʻilio ʻana ma ka lewa hohonu me ka hoʻohana ʻana i nā alapine lekiō. Eia nō naʻe, ʻaʻole hiki i ka ʻōnaehana e pili ana i ke alapine lekiō ke hoʻokō i nā pono kamaʻilio o kēia manawa a me ka wā e hiki mai ana o ka ʻāpana lewa ma muli o ka bandwidth palena a me ke koi e hoʻonui mau nei i nā wikiwiki hoʻoili ʻikepili kiʻekiʻe.
Ma ka ʻaoʻao ʻē aʻe, hāʻawi ka kamaʻilio laser a i ʻole optical i nā pono he nui ma ke ʻano o nā bandwidth nui, nā loulou wikiwiki ʻikepili kiʻekiʻe a me nā kikowaena SWaP haʻahaʻa (ka nui, ke kaumaha a me ka mana). Loaʻa iā ia ka hiki ke hoʻonui i nā wikiwiki ʻikepili 10 a 100 mau manawa o ka hiki o ka hapa nui o nā ʻōnaehana lekiō akamai e hoʻohana nei i kēia manawa a hiki ke uhaki i nā palena kamaʻilio. No laila, he mea nui e hoʻolaha i nā kamaʻilio optical no nā kamaʻilio ākea hohonu kiʻekiʻe e hiki ke hoʻokō i nā pono hoʻoili ʻikepili interplanetary i ka wā e hiki mai ana.
ʻO ka hoʻokolohua Deep Space Optical Communications (DSOC) he ukana hōʻike ʻenehana ma luna o ka mokulele Psyche e holo nei ma ka lewa hohonu i ka asteroid Psyche waiwai metala i loaʻa ma ke kāʻei asteroid ma waena o Mars a me Jupiter. I Dekemaba 2023, ua hōʻike ʻo ia i nā kamaʻilio bandwidth kiʻekiʻe ma ka lewa hohonu i ka wā i hoʻouna ai i ka Honua i kahi wikiō wehewehe kiʻekiʻe loa ma o ka laser mai 32 miliona km ma ka lewa hohonu. ʻO kēia ka hōʻike mua o nā kamaʻilio optical ma ʻō aku o ka Mahina.
ʻO ka Deep Space Network (DSN) kahi pūnaewele o nā pono i loaʻa ma nā wahi like ʻole o ka honua e kamaʻilio me nā mokulele mamao e ʻimi ana i ka ʻōnaehana lā. Ua loaʻa i kahi antenna hoʻokolohua o kēia pūnaewele nā hōʻailona lekiō a me ka laser i hoʻouna ʻia mai ka mokulele Psyche ma ka lewa hohonu. Hōʻike kēia e hiki ke hoʻoponopono hou ʻia nā antenna DSN e kamaʻilio nei me nā mokulele ma o nā hōʻailona lekiō no nā kamaʻilio laser.
