James Webb Uzay Teleskobu Bir Uzay Taşından Hasar Gördü

Derin uzayın en çarpıcı görüntülerinden bazıları halihazırda James Webb Uzay Teleskobu (JWST) tarafından çekilmektedir. Mayıs ayında bir mikrometeoritin JWST'ye çarpması, önceden düşünülenden daha endişe vericidir.

Bir gazeteye göre bir ayna segmenti tamamen telafi edilemeyecek hasarlara maruz kaldı. Hizmete alma sırasında uzay teleskopu iyi performans gösterdi. Webb'in gözlemevinin büyük aynasına Mayıs ayında yaklaşık altı kez vuruldu.

Beş saldırıda ihmal edilebilir hasar oluştu. Rapora göre 1 nanometreden daha az dalga cephesi hatasına neden olacaklar.

Bu nedenle, bu vuruşların neden olduğu bozulma düzeltilebilir ve nihai sonuçtan silinebilir. Ancak Mayıs ortasındaki altıncı saldırı teleskopta daha ciddi hasara neden oldu.

22 - 24 Mayıs 2022 arasındaki mikrometeorit çarpması, UT'nin fırlatma öncesi hasar beklentilerini aşarak JWST Projesi tarafından daha fazla araştırma ve modelleme yapılmasını tetikledi.

Her altıgen parça JWST'nin yüzünü oluşturur. Yıldız ışığı ayrı ayrı yakalanıp pozlanabilir ve hassas şekilde ayarlanabilir.

Mikrometeorit en ciddi şekilde hasar görmüş ayna segmenti C3'ü çarpmaktadır. Araştırma, her ayna parçasını ayarlayarak olumsuz etkiyi en aza indirebilir. Hatayı tam olarak telafi etmenin bir yolu yoktur.

Darbenin bir sonucu olarak, JWST aynasının tamamı için toplam dalga cephesi hatası, sonraki iki yeniden hizalamanın ardından yaklaşık 5-10 nanometre arttı. İdealden yüksek olmasına rağmen bu kabul edilebilir.

Mikro meteoritler JWST'ye zarar verebilir. Yapısı bunu açıklıyor. Uzay, Webb'in Hubble'ın ana aynasının içine yerleştirilmiş 6.5 metrelik parçalı aynasına maruz kalıyor.
