أفضل صور التقطتها "روزيتا" خلال ملحمة الـ12 عاما الفضائية

قامت وكالة الفضاء الأوروبية بنشر الصور الأخيرة التي التقتها المركبة الفضائية روزيتا للمذنب "67 بي عن قرب، قبل الاصطدام به وفقدان الاتصال بشكل دائم مع الأرض.

وتظهر الصور المشوشة، التي التقطتها المركبة التابعة لوكالة الفضاء الأوروبية بواسطة كاميرا أوزيريس عريضة الزاوية، الصخور والتضاريس الوعرة للمذنب.

وقد التقطت الصور على بعد 20 مترا فوق سطح المذنب قبل أن تقوم غرفة التحكم في وكالة الفضاء الأوروبية بتوجيه روزيتا التي بلغت تكلفتها 1.5 مليار دولار نحو الصخور على سطح المذنب لتنهي بذلك مهمتها التي دامت 12 عاما.

كما تم التقاط صور عن بعد 16 كيلومترا من سطح المذنب "67 بي" حيث يظهر قمر غريب في الفضاء السحيق كخلفية له.

ويواصل الباحثون من وكالة الفضاء الأوروبية تحليل عدد من الصور التي التقطت بواسطة روزيتا في أثناء مسارها نحو التحطم على سطح المذنب.

Scientists are combining my data with ground-based observations to learn more not only about #67P but also other comets! #CometLanding pic.twitter.com/Vu35JZ71Lu

And here's #comet #67p on which our #Rosetta #spacecraft will make a controlled #impact 30 September 2016. 🚀🛰🌠 Earlier this year, Rosetta's OSIRIS wide-angle camera captured an outburst from the "Atum" region of the comet. The images are separated by half an hour each and as such show the comet rotating. 📷📷📷 Follow us as the wonderful adventure of #ESA's Rosetta mission comes to a natural end, with the Rosetta #orbiter joining the #Philae lander on the comet's surface. #awesome #cometwatch #livingwithacomet #cometlanding #europeanspaceagency #esa #timeflies #space #instaspace #67p #theend #solarsystem #cosmos #bw #gif #animation #video #chury

#Repost @rosettamission ・・・ #Rosetta recently took a new image of its #cometlanding site on #comet #67P/C-G, on 18 September 2016, when the #spacecraft was 12.1 km from the centre of the comet. The spacecraft will #touchdown on the comet and conclude its #mission next Friday, 30 September. We'll keep you posted here on @instagram as well! 📷📷📷 The image depicts the dust-covered terrains of Ma'at, on the small comet lobe, where Rosetta is destined to make a controlled #impact next week. The spacecraft will aim at a point just right of the image centre, next to Deir el-Medina, the large pit located slightly below and to the right of centre in this view. 🛰🛰🛰 At the scale of today's #CometWatch – 1.0 m/pixel – the main structure of Rosetta would span roughly 2 x 2 pixels; taking into account its two solar panels, the entire structure would span about 32 pixels across. (The image measures about 1.1 km across.) Deir el-Medina is about 130 m-wide and, like other pits located in the Ma'at region, exhibits intriguing metre-sized lumpy structures called ‘goosebumps’ on its internal walls. During the descent, Rosetta will collect unprecedented #close-up views of these structures, which scientists believe could be the signatures of early ‘cometesimals’ that assembled to create the comet in the early phases of #SolarSystem formation. 📷📷📷 Credits: ESA/Rosetta/NAVCAM – @creativecommons #CC BY-SA IGO 3.0 🌌🌌🌌 #creativecommons #esa #europeanspaceagency #livingwithacomet #finalcountdown
