ESA imawulula zatsopano zokhudzana ndi ntchito ya Hera, yomwe imayesetsa kupeza mayankho kwa mfuti

ESA

Ndizowona kuti osati kalekale NASA idalankhula pagulu ku Boma la United States njira yodziwikiratu kuti anthu aku America, kuphatikiza anthu onse Padziko lapansi, akuyenera kuthandizirana kuti akwaniritse, momwe zingathere, kuti apulumuke pa dziko lathu lisanachitike kuposa kugunda kwa asteroid yayikulu motsutsana ndi Earth yomwe.

Ino ndi nthawi yolankhula za ntchito ya Hera momwe asayansi ndi ofufuza ochokera ku ESA, European Space Agency, akugwira ntchito. Inemwini, ndikuyenera kuvomereza kuti cholinga cha Hera cholinga chake, monga momwe zilili ndi mapu ochitidwa ndi NASA, kuti athetse yankho loti asteroid kapena chinthu china chachikulu chimagunda Dziko lapansi, nthawi ino chowonadi ndichakuti ku ESA amapita patsogolo pang'ono chifukwa, mwa malingaliro awo, ndikuphunzira chimodzi mwazinthuzi ndipo pezani njira yabwino yosinthira njira yake.

ESA ikugwira kale ntchito yopititsa patsogolo ntchito ya Hera

Kupita mwatsatanetsatane, zomwe ESA ikugwira ntchito ndi pulani yomwe cholinga chake chachikulu ndikutumiza mtundu wina wa kafukufuku ku pulogalamu ya asteroid mu 2026. Pakadali pano ntchitoyi ili kale mu gawo la uinjiniya ndipo lingaliro ndilakuti izi kafukufuku wokhoza akhoza pitani ku machitidwe a Didymos, wopangidwa ndi Didymain, chinthu chotalika pafupifupi 780 metres pomwe Didymoon imazungulira, mtundu wa mwezi pafupifupi 160 mita m'mimba mwake.

Monga mukuwonera, tikukamba za zinthu ziwiri zazikulu kwambiri, kuti ndikupatseni lingaliro, Didymain ikadakhala ngati kukula kwa phiri pomwe mwezi wake, Didymoon ndi waukulu, pafupifupi ngati piramidi ya Giza, zinthu zomwe zili ndi kukula kwakukulu monga Kukhala cholinga chofufuzira ma asteroid komanso kuyesa zingapo komanso kuyesa zina zotheka kuteteza mapulaneti. Mfundo ina yofunika kukumbukira ndikuti, mpaka pano, kachitidwe bayinare sizinayambe anafufuzidwa kale Chifukwa chake, monga ofufuza atsimikizira, zozizwitsa zambiri zikuyembekezeka.

Zingakhale bwanji choncho, makamaka chifukwa cha zovuta zambiri zomwe gulu la mainjiniya ndi ofufuza omwe akupanga ntchitoyi akuyenera kukumana nawo, asankha kuphatikiza gawo lalikulu la timu yomwe panthawiyo, adachita nawo ziwonetsero za Rosetta , chokumana nacho chomwe ndichofunikira chifukwa ayenera kuthana ndi zovuta zosiyanasiyana zokhudzana, mwachitsanzo, ndi kalozera ndi machitidwe oyenda ndipo ngakhale ndi mphamvu yokoka yotsika kwambiri.

Hera ayamba njira yake pambuyo pa ntchito ya NASA ya DART

Monga zawululidwa ndi ESA yomwe, cholinga cha ntchitoyi yonse, ndikumvetsetsa momwe zinthuzi zimagwirira ntchito mlengalenga, kupanga mapu kuti adziwe mawonekedwe a Didymoon, imodzi mwama asteroid ofunikira kwambiri. apezeka mpaka pano. Pofuna kukwaniritsa ntchitoyi, mgwirizano wa NASA, yemwe ntchito yake Kuyesa Kwachiwiri Kobwezeretsanso Asteroid (DART) ndikofunikira.

Ntchito yomwe NASA ichite idzakhala yofunika chifukwa, malinga ndi zomwe bungweli linanena, 2022 imodzi mwa kafukufuku wake idzakhudzidwa ndi Didymoon ku yesetsani kusinthitsa mwezi uno kuchokera pa njira yomwe ikuzungulira Didymain. Izi zikhala zoyambirira kuchitidwa ndi anthu ndipo ndipamene Hera atha kutipatsa chidziwitso chofunikira pazosintha zomwe zidachitika munjira yamabinawo.

Monga tafotokozera Ian Carnelli, Woyang'anira ntchito ya Hera m'mawu ake:

Dongosolo la Didymos ndiye malo oyeserera oyeserera poyeserera mapulaneti, komanso ndi malo atsopano ofufuzira za asteroid. Ngakhale ma binaries amapanga 15% ya ma asteroid onse odziwika, sanawunikiridwepo kale, ndipo tikuyembekezera zodabwitsa zambiri.

Kafukufuku wa Hera atipatsa kuchuluka kwa Didymoon, mawonekedwe a crater, komanso mphamvu zakuthupi za Didymoon. Zonse zomwe zasonkhanitsidwa pambuyo pa kukhudzidwa kwa DART ndi kuphunzira kwa Hera zitha kukhala njira zodzitetezera pamapulaneti ndipo zitha kubwerezedwa ngati tifunikira kuyimitsa asteroid yomwe ikubwera.


Zomwe zili m'nkhaniyi zikutsatira mfundo zathu za malamulo okonzekera. Kuti mufotokoze cholakwika dinani Apa.
