تکنولوژی الکترونیک - ابداع لیزر جدید استرالیایی برای ردیابی زباله‌های فضایی

نوع مطلب: تازه ها ،

به گزارش (ایسنا)، به گفته كارشناسان زباله‌هایی كه در مدار زمین در گردش هستند، تهدید بزرگی برای ماهواره‌ها و فضانوردان محسوب می‌شوند.

اخیرا شاتل و ایستگاه فضایی بین‌المللی ناچار شدند كه به دلیل نزدیك شدن این زباله‌ها مسیر حركت خود را تغییر دهند تا با آنها برخورد نكنند.

در این تحقیق جدید به منظور ردیابی بهتر زباله‌های فضایی محققان استرالیایی در مركز سیستم‌های فضایی EOS در كانبرا، طراحی یك سیستم جدید ردیاب لیزری را آغاز كرده‌اند.

كاریگ اسمیت، رییس اجرایی این مركز علمی در این باره خاطر نشان كرد: این فن‌آوری جدید از لیزرهای مادون قرمز برای شناسایی و دنبال كردن زباله‌های فضایی استفاده می‌كند، كاری كه پیش از این انجام نشده است.

محققان می‌گویند: با این فن‌آوری جدید می‌توان محل دقیق ماهواره‌ها و بقایای راكت‌های از رده خارج شده را كه در مدار زمین سرگردان هستند، شناسایی كرد.

به گفته دانشمند‌ان استرالیایی ، در حال حاضر سیستم دفاعی آمریكایی، بسیاری از زباله‌ها را با رادار ردیابی می‌كند، اما این رادار همیشه نمی‌تواند دقت كافی داشته باشد.

Superb blog! Do you have any helpful hints for aspiring writers?
I'm planning to start my own blog soon but I'm a little lost on everything.
Would you propose starting with a free platform
like Wordpress or go for a paid option? There are so
many choices out there that I'm totally confused .. Any recommendations?
Cheers!
