M\u0117nulis nuolat patiria kosmini\u0173 k\u016bn\u0173 sm\u016bgius, ta\u010diau \u0161\u012fkart objektas bus \u017eemi\u0161kos kilm\u0117s. Nepriklausomas astronomas Billas Gray\u2019us skelbia, kad panaudota \u201eSpaceX\u201c raketos \u201eFalcon 9\u201c antroji pakopa 2026 met\u0173 rugpj\u016b\u010dio 5 dien\u0105 tur\u0117t\u0173 atsitrenkti \u012f M\u0117nulio pavir\u0161i\u0173.<\/p>\n

Jo vertinimu, sm\u016bgis \u012fvyks apie 06:44 pasauliniu koordinuotu laiku ir greitis gali siekti ma\u017edaug septynis kartus didesn\u012f u\u017e garso greit\u012f. Prognozuojama vieta siejama su Ein\u0161teino kraterio apylink\u0117mis, netoli ribos tarp matomosios ir nematomosios M\u0117nulio pusi\u0173.<\/p>\n

Kas tai per objektas?<\/h2>\n

Kalbama apie \u201eFalcon 9\u201c vir\u0161utin\u0119 pakop\u0105, kuri po naudingosios apkrovos atskyrimo neliko kontroliuojamai sugr\u0105\u017einta \u012f atmosfer\u0105. \u201eFalcon 9\u201c yra i\u0161 dalies pakartotinai naudojama raketa: pirmoji pakopa da\u017enai gr\u012f\u017eta ir nutupia, o antroji paprastai lieka orbitoje.<\/p>\n

Anot B. Gray\u2019aus, \u0161i konkreti pakopa po 2025 met\u0173 saus\u012f \u012fvykdyto paleidimo liko pailgoje orbitoje aplink \u017dem\u0119. Per vien\u0105 apsisukim\u0105 ji u\u017etrunka apie 26 dienas, o trajektorija periodi\u0161kai priart\u0117ja prie M\u0117nulio orbitos srities, tod\u0117l laikui b\u0117gant susidaro reali susid\u016brimo tikimyb\u0117.<\/p>\n

Kod\u0117l prognozuoti sud\u0117tinga?<\/h2>\n

Nors pagrindines orbitos tendencijas lemia \u017dem\u0117s, M\u0117nulio, Saul\u0117s ir kit\u0173 planet\u0173 gravitacija, papildom\u0105 \u012ftak\u0105 daro Saul\u0117s spinduliuot\u0117s sl\u0117gis. \u0160i j\u0117ga nedidel\u0117, bet ilgainiui gali pastebimai pakeisti trajektorij\u0105, ypa\u010d kai objektas sukasi ir nevienodai atspindi \u0161vies\u0105.<\/p>\n

\u201eKosmini\u0173 \u0161iuk\u0161li\u0173 jud\u0117jimas da\u017eniausiai yra prognozuojamas, ta\u010diau Saul\u0117s spinduliuot\u0117s sl\u0117gis per laik\u0105 gali prid\u0117ti netik\u0117tumo\u201c, \u2013 sak\u0117 Billas Gray\u2019us.<\/p>\n

Ar tai pavojinga ir k\u0105 tai sako apie problem\u0105?<\/h2>\n

Tiesiogin\u0117s gr\u0117sm\u0117s \u017emon\u0117ms \u0161is sm\u016bgis nekels, nes M\u0117nulyje n\u0117ra gyventoj\u0173, o kritimas vyks toli nuo bet kokios vykdomos veiklos. Vis d\u0117lto incidentas i\u0161ry\u0161kina augan\u010di\u0105 kosmini\u0173 \u0161iuk\u0161li\u0173 problem\u0105 ir tai, kad vir\u0161utini\u0173 pakop\u0173 \u201epalikimas likimo valiai\u201c ilgainiui sukuria neplanuot\u0173 susid\u016brim\u0173 rizik\u0105.<\/p>\n

Pastaraisiais de\u0161imtme\u010diais M\u0117nulyje b\u016bta ir ty\u010dini\u0173 sm\u016bgi\u0173, vykdyt\u0173 moksliniais tikslais, pavyzd\u017eiui, kai NASA misija LCROSS 2009 metais suk\u0117l\u0117 dulki\u0173 debes\u012f ir pad\u0117jo patvirtinti vandens ledo p\u0117dsakus \u0161e\u0161\u0117liuotuose krateriuose. 2022 metais taip pat fiksuotas nevaldomas raketos pakopos sm\u016bgis, po kurio M\u0117nulio orbitoje esantys aparatai u\u017efiksavo nauj\u0105 krater\u012f.<\/p>\n

Mokslininkai atkreipia d\u0117mes\u012f, kad did\u0117jant paleidim\u0173 skai\u010diui vis svarbesni tampa ai\u0161k\u016bs tarptautiniai principai, kaip valdyti raket\u0173 pakop\u0173 \u201egyvenimo pabaig\u0105\u201c. Vienas prakti\u0161k\u0173 sprendim\u0173, apie kur\u012f kalba ir B. Gray\u2019us, yra vir\u0161utines pakopas nukreipti \u012f tokias trajektorijas, kad jos palikt\u0173 \u017dem\u0117s ir M\u0117nulio aplink\u0105 ir nebekelt\u0173 susid\u016brimo rizikos artimiausiu laikotarpiu.<\/p>\n","protected":false},"excerpt":{"rendered":"
