ESA's PROBA-3 mission, iyo yakasimudzwa paISRO's PSLV-XL roketi musi wa5 Zvita 2024, i "solar eclipse-kugadzira" maviri satellite magadzirirwo emaocculter uye coronagraph spacecrafts. Ichagonesa kutariswa kwesolar corona ne coronagraph spacecraft kwemaawa matanhatu muawa imwe neimwe 6h maminetsi makumi matatu nenhanhatu kutenderera kuburikidza-inoda kusikwa kwekuora kwezuva kwese kwezuva neocculter spacecraft yekuumbwa. Sekuratidzwa kwekugadzira tekinoroji dzekubhururuka, PROBA-19 mission inovhura nzira yeramangwana interferometry-based LISA mission (iyo ichange iri kuumbwa kwezvitatu zvemuchadenga munzvimbo) yekuona yakaderera frequency gravitational waves (GWs).
Iyo Laser Interferometer Space Antenna (LISA) mission yakagamuchira ESA's kuenda mberi kutanga kwegore rino uye yakarongerwa kutangwa muna 2035, ichave yekutanga space-based gravitational wave observatory yakatsaurirwa kuona uye kudzidza yeakaderera frequency gravitational waves (GWs) ine frequency pakati pe 0.1 mHz uye 1 Hz (kana millihertz ripples) zvichikonzerwa nekukanganiswa kwemucheka wenguva-yepakati universe. Ichave nyeredzi yezvitundumuseremusere zvitatu mukuumbwa kwakaenzana kwegonyonhatu muchadenga. Rutivi rumwe norumwe rwegonyo yacho ruchareba 2.5 miriyoni km. Kugadzirwa kwezvitundumuseremusere zvitatu kuchatenderera Zuva muEarth-trailing heliocentric orbit pakati pe50 ne65 miriyoni km kubva paPasi uku ichichengetedza kureba kwepakati-muchadenga chinhambwe chekuparadzana chemakiromita 2.5 miriyoni.
LISA mishoni ichavaka pane maviri akakosha masimba - "yakaderera-frequency gravitational wave yekuona munzvimbo" uye "chaizvo kuumbwa kubhururuka muchadenga". Nepo tekinoroji yaidiwa "yakaderera-frequency gravitational wave yekuona munzvimbo" yakaedzwa mukubhururuka uye yakaratidzwa neLISA Pathfinder mishoni panguva ya2015-2017, tekinoroji ye "chaizvo kuumbwa kubhururuka muchadenga" ichangobva kuratidzwa pa5 Zvita 2024 ne. iyo "yakazara solar eclipse-inogadzira maviri setiraiti maumbirwo ePROBA-3 mishoni" ichipinda yakanyanya elliptical orbit. Yakanga yasimudzwa paISRO's PSLV-XL roketi.
PROBA (Project for On-Board Autonomy) -3 mission yeEuropean Space Agency (ESA) ine zvinangwa zviviri zvakakosha: kuratidzira kwekugadzira tekinoroji yekubhururuka, uye kudzidza kwemukati mezuva corona.
PROBA-3 ndiyo yekutanga "chaizvo kugadzirwa kubhururuka" mishoni. Iko kuumbwa kwezvipenga zviviri: occulter uye coronagraph. Iyo yekutanga (kureva, Occulter spacecraft) inokanda mumvuri wakanyatso kudzora paCoronagraph spacecraft kuti ibudise kunyura kwezuva pakudiwa kwemaawa matanhatu panguva, zvichigonesa kutarisisa kwesolar isingaite zvishoma. Iwo maviri spacecrafts mukugadzirwa akaparadzaniswa nechinhambwe chemamita zana nemakumi mashanu nekurongeka kwemamirimita mashoma. Kuumbwa kwakanyatso kubhururuka kwemayuniti anozvitonga muchadenga kufambira mberi kwakakosha muhunyanzvi hwemuchadenga kunovhura mukana wekuita mishoni nyowani senge interferometry-based LISA mission yekuona yakaderera frequency gravitational waves (GWs) muchadenga chisingaonekwe pachishandiswa pasi-based detectors. senge LIGO, VIRGO, nezvimwe kana Pulsar Timing Arrays (PTAs).
Nepo kuumbwa kwezvitundumuseremusere zvitatu mumishini yeLISA kuchagonesa kuyerwa (kuburikidza nelaser interferometry) yeshanduko diki diki munhambwe dziri pakati pezviyedzo zvemuchadenga zvinokonzerwa nemagetsi anokwevera pasi, kuumbwa kwezvikepe zviviri muPROBA -3 mishoni kwakagadzirirwa kugonesa kucherechedzwa. solar corona by coronagraph spacecraft kwemaawa matanhatu muawa imwe neimwe 6h maminetsi makumi matatu nenhanhatu inotenderera nepakati pekuda kusikwa kwekuora kwezuva kwese kwezuva nemusvikiro. spacecraft yekugadzira.
Zviitiko zvechisikigo zvekuora kwezuva hazvipi mikana yakakwana yekuona mamiriro ekunze ezuva nekudaro pamukana wekuda wakapihwa nePROBA-3 uchabatsira zvakanyanya mukudzidza nezve solar corona uye zvinosanganisirwa zviitiko zvekufungidzira zvirinani zvemamiriro ekunze uye madutu ezuva ayo anozivikanwa kukanganisa masetellite, zvivakwa zvekutaurirana uye magetsi emagetsi paPasi.
