ʻO ka huakaʻi PROBA-3 a ESA, ka mea i hoʻokiʻekiʻe ma luna o ka ISRO's PSLV-XL rocket i ka lā 5 Dekemaba 2024, he "hana eclipse solar" ʻelua o ka hoʻokumu ʻana o ka occult a me ka coronagraph spacecrafts. Hiki iā ia ke nānā aku i ka corona lā e ka coronagraph spacecraft no 6 mau hola i kēlā me kēia 19h hola 36 minuke orbit ma o ke koi ʻana i ka hoʻokumu ʻia ʻana o ka pohā o ka lā e ka occult spacecraft o ka hoʻokumu ʻana. E like me ka hōʻike ʻana o ka hoʻokumu ʻana i nā ʻenehana lele, ua hoʻolale ʻia ka misionari PROBA-3 i ke ala no ka mikiona LISA i hoʻokumu ʻia interferometry e hiki mai ana (ʻo ia ka hoʻokumu ʻana o ʻekolu mau mokulele i ka lewa) no ka ʻike ʻana i nā hawewe umekaumaha haʻahaʻa (GWs).
ʻO ka mission Laser Interferometer Space Antenna (LISA) i loaʻa iā ESA i ka hoʻomaka ʻana o kēia makahiki a ua hoʻomaka ʻia e hoʻomaka ʻia i 2035, ʻo ia ka mākaʻikaʻi nalu gravitational mua i hoʻolaʻa ʻia no ka ʻike ʻana a me ke aʻo ʻana i nā hawewe haʻahaʻa haʻahaʻa haʻahaʻa (GWs) me alapine (frequency) ma waena o 0.1 mHz a me 1 Hz (a i ʻole nā millihertz ripples) i hana ʻia e ka hoʻoneʻe ʻana i ka lole o ka manawa-manawa ma ke ao holoʻokoʻa. He hui ia o ʻekolu mau mokulele i loko o ka hoʻokumu ʻia ʻana o ka triangle equilateral pololei ma ka lewa. He 2.5 miliona km ka lōʻihi o kēlā me kēia ʻaoʻao o ka huinakolu. ʻO ka hoʻokumu ʻia ʻana o nā mokulele mokulele ʻekolu e hoʻopuni ana i ka Lā ma kahi orbit heliocentric ma waena o 50 a me 65 miliona km mai ka Honua me ka mālama ʻana i kahi mamao kaʻawale ma waena o nā mokulele he 2.5 miliona km.
E kūkulu ʻia ka misionari LISA ma luna o ʻelua mau mea koʻikoʻi - "ʻike haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa i ka lewa" a me "ka hoʻokumu pololei ʻana e lele ana i ka lewa". ʻOiai ua hoʻāʻo ʻia ka ʻenehana e pono ai no ka "ʻike haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa i ka lewa" i ka lele a hōʻike ʻia e ka misionari LISA Pathfinder i ka makahiki 2015-2017, ua hōʻike ʻia ka ʻenehana no ka "hoʻokumu pololei e lele ana i ka lewa" i ka lā 5 Dekemaba 2024 me ʻo ka "total solar eclipse-making two satellite formation of PROBA-3 mission" e komo ana i ka orbit elliptical kiʻekiʻe. Ua hoʻokiʻekiʻe ʻia ma luna o ka mokuahi PSLV-XL o ISRO.
ʻO PROBA (Project for On-Board Autonomy) -3 mission o European Space Agency (ESA) he ʻelua mau pahuhopu nui: hōʻike i ka hoʻokumu ʻana i nā ʻenehana lele, a me ke aʻo ʻana i ka corona solar i loko.
ʻO PROBA-3 ka mikiona mua loa o ka "lele hoʻokumu pololei". ʻO ia ka hoʻokumu ʻana o ʻelua mau mokulele mokulele: occult a me ka coronagraph. ʻO ka mua (ʻo ia hoʻi, ʻo Occult spacecraft) e hoʻolei i kahi aka i hoʻomalu pono ʻia ma luna o ka mokuahi Coronagraph e hana i nā eclipses o ka lā ma ke koi ʻana no ʻeono hola i ka manawa, e hiki ai ke nānā aku i ka corona solar nui loa. Hoʻokaʻawale ʻia nā mokulele ʻelua i ka hoʻokumu ʻia e kahi mamao o 150 mika me ka pololei o ʻelua mau millimeters. ʻO ka lele ʻana o nā ʻāpana autonomous i ka lewa kahi holomua nui i ka ʻenehana ākea e wehe ana i ka hiki ke hana i nā mikiona hou e like me ka mikiona LISA interferometry-based no ka ʻike ʻana i nā nalu haʻahaʻa haʻahaʻa haʻahaʻa (GWs) i ka lewa i hiki ʻole ke ʻike ʻia me ka hoʻohana ʻana i nā mea ʻike honua. e like me LIGO, VIRGO, etc. a i ʻole Pulsar Timing Arrays (PTAs).
ʻOiai ke kūkulu ʻia ʻana o ʻekolu mau mokulele i loko o ka mikiona LISA e hiki ai ke ana (ma o ka laser interferometry) o nā loli liʻiliʻi loa i nā mamao ma waena o nā nui hoʻāʻo i nā mokulele i hoʻokumu ʻia e ka gravity ripples, ua hoʻolālā ʻia ka hoʻokumu ʻana o ʻelua mau mokulele i loko o ka misionari PROBA –3 e hiki ai ke nānā aku ʻO ka corona solar e ka coronagraph spacecraft no 6 mau hola i kēlā me kēia 19h hola 36 minuke orbit ma o ke koi ʻana i ka hana ʻana i ka pohā o ka lā holoʻokoʻa e ka mokuahi occult o ka hoʻokumu ʻana.
ʻAʻole lawa nā hanana eclipse o ka lā kūlohelohe i nā manawa kūpono e nānā ai i ka lewa o waho o ka lā no laila ke noi ʻia ka manawa i hāʻawi ʻia e PROBA-3 e kōkua nui i ke aʻo ʻana i ka corona solar a me nā mea e pili ana no ka wānana ʻoi aku ka maikaʻi o ka lewa a me nā ʻino o ka lā. hoʻopau i nā satelite, nā ʻōnaehana kamaʻilio a me nā pūnaewele mana ma ka Honua.
