العربية: التعليق الأصلي: خلال اختبارات التجميد، سوف تُعرَّض المرايا إلى درجات حرارة تنخفض تدريجيًّا وُصولًا إلى 24 كلڤن، مما سيسمح للمُهندسين أن يقيسوا كيفيَّة تغيُّر شكل كُل مرآة على حدى خِلال تبرُّدها، وذلك بِدقَّةٍ كبيرة. لِمزيدٍ من المعلومات: اضغط هُنا
English: Caption: During cryogenic testing, the mirrors will be subjected to temperatures dipping to 24 Kelvins, permitting engineers to measure in extreme detail how the shape of each mirror changes as it cools. More information: Click here
