K\u00fc\u00e7\u00fck bir uzay arac\u0131, Didymos isimli asteroidin uydusu Dimorphos\u2019a saatte yakla\u015f\u0131k 22 bin 500 kilometre h\u0131zla \u00e7arparak onu y\u00f6r\u00fcngesinden sapt\u0131rm\u0131\u015ft\u0131. Bu, insanl\u0131k ad\u0131na bir ilkti.<\/p>\n

Ancak aradan ge\u00e7en \u00fc\u00e7 y\u0131lda, \u00e7arpman\u0131n etkilerine dair yeni veriler beklenmedik sonu\u00e7lar\u0131 ortaya \u00e7\u0131kard\u0131.<\/p>\n

UZAYA SAVRULAN PAR\u00c7ALAR YEN\u0130 B\u0130R D\u0130NAM\u0130K<\/strong><\/h3>\n

Ge\u00e7en hafta Planetary Science Journal dergisinde yay\u0131mlanan ara\u015ft\u0131rmaya g\u00f6re, Maryland \u00dcniversitesi liderli\u011findeki bir astronom ekibi, \u00e7arpman\u0131n sadece asteroidi sapt\u0131rmakla kalmay\u0131p b\u00fcy\u00fck miktarda kaya par\u00e7as\u0131n\u0131 uzaya savurdu\u011funu belirledi. Bu kaya par\u00e7alar\u0131n\u0131n baz\u0131lar\u0131n\u0131n, \u00e7arpan uzay arac\u0131n\u0131n ta\u015f\u0131d\u0131\u011f\u0131 enerjinin \u00fc\u00e7 kat\u0131ndan fazlas\u0131na sahip oldu\u011fu tespit edildi.<\/p>\n

Ara\u015ft\u0131rman\u0131n ba\u015fyazar\u0131 ve Maryland \u00dcniversitesi’nden ara\u015ft\u0131rmac\u0131 Tony Farnham, \u201cBir asteroidi y\u00f6r\u00fcngesinden \u00e7\u0131karmay\u0131 ba\u015fard\u0131k. DART\u2019\u0131n do\u011frudan etkisi bu de\u011fi\u015fimi sa\u011flad\u0131, ancak savrulan kayalar da neredeyse ayn\u0131 b\u00fcy\u00fckl\u00fckte ek bir itki olu\u015fturdu\u201d dedi.<\/p>\n

Farnham, bu durumun gezegeni koruma g\u00f6revlerinde dikkate al\u0131nmas\u0131 gereken yeni fiziksel dinamikler yaratt\u0131\u011f\u0131n\u0131 s\u00f6yl\u00fcyor.<\/p>\n

\u0130talyan Uzay<\/a> Ajans\u0131 taraf\u0131ndan geli\u015ftirilen ve \u00e7arpma sonras\u0131 b\u00f6lgeyi g\u00f6zlemlemek \u00fczere konu\u015fland\u0131r\u0131lan LICIACube adl\u0131 k\u00fc\u00e7\u00fck bir uzay arac\u0131 sayesinde bilim insanlar\u0131, Dimorphos\u2019tan savrulan 104 kaya par\u00e7as\u0131n\u0131 takip etmeyi ba\u015fard\u0131. Bu par\u00e7alar\u0131n \u00e7aplar\u0131 20 santimetreden 3,6 metreye kadar de\u011fi\u015fiyordu. Ancak ara\u015ft\u0131rmac\u0131lar bu kayalar\u0131n uzaya rastgele da\u011f\u0131lmad\u0131\u011f\u0131n\u0131 fark etti.<\/p>\n

Farnham bu g\u00f6zlemi, \u201cKaya par\u00e7alar\u0131n\u0131n uzayda rastgele da\u011f\u0131lmad\u0131\u011f\u0131n\u0131 g\u00f6rd\u00fck. \u0130ki belirgin k\u00fcme halinde toplanm\u0131\u015flard\u0131 ve di\u011fer b\u00f6lgelerde neredeyse hi\u00e7 materyal yoktu. Bu da burada hen\u00fcz anlayamad\u0131\u011f\u0131m\u0131z bir \u015feyin etkili oldu\u011funu g\u00f6steriyor\u201d diyerek a\u00e7\u0131klad\u0131.<\/p>\n

\u00c7ARPI\u015eMADAN \u00d6NCE NE OLDU?<\/strong><\/h3>\n

Ara\u015ft\u0131rmac\u0131lar, DART uzay arac\u0131n\u0131n \u00fczerindeki g\u00fcne\u015f panellerinin, \u00e7arp\u0131\u015fmadan hemen \u00f6nce Atabaque ve Bodhran adl\u0131 iki b\u00fcy\u00fck kayaya \u00e7arpm\u0131\u015f olabilece\u011fini d\u00fc\u015f\u00fcn\u00fcyor.<\/p>\n

Maryland \u00dcniversitesi’nden astronomi profes\u00f6r\u00fc Jessica Sunshine, DART\u2019\u0131n y\u00fczeyi iri kayalarla kapl\u0131 kaotik bir alana \u00e7arpt\u0131\u011f\u0131n\u0131, bunun da savrulan materyalin ipliksi ve da\u011f\u0131n\u0131k bir yap\u0131 kazanmas\u0131na yol a\u00e7t\u0131\u011f\u0131n\u0131 belirtti.<\/p>\n

Avrupa Uzay Ajans\u0131\u2019n\u0131n 2026’da ula\u015fmas\u0131 planlanan Hera misyonu sayesinde, Dimorphos ve \u00e7evresinin durumu bir kez daha do\u011frudan g\u00f6zlemlenebilecek. Bu da bilim insanlar\u0131na \u00e7ok daha net veriler sunacak.<\/p>\n

Sunshine, gelecekteki benzer g\u00f6revlerin planlanmas\u0131nda bu t\u00fcr detaylar\u0131n hayati \u00f6neme sahip oldu\u011funu vurguluyor:<\/p>\n

\u201cE\u011fer \u00fczerimize do\u011fru gelen bir asteroidi belirli bir miktar sapt\u0131rmam\u0131z gerekiyorsa, t\u00fcm bu ince ayr\u0131nt\u0131lar son derece kritik hale geliyor. Bunu bir kozmik bilardo oyunu gibi d\u00fc\u015f\u00fcnebilirsiniz. E\u011fer t\u00fcm de\u011fi\u015fkenleri hesaba katmazsak, topu deli\u011fe sokamayabiliriz.\u201d<\/p>\n<\/div>\n
