📡 سیارکِ #بنو [‌Bennu] با عمری بیش از ۴.۵ میلیارد سال، غنی از مواد آلی و کربنی است. فضاپیمای OSIRIS-REx یا O-Rex ناسا در ۱۸ شهریور ۱۳۹۵ به‌سمت این سیارک ارسال شد [🔗].

🔺 فضاپیما در مدارهایی پیچیده، سیارک را از نظر شکل، ابعاد، جرم، چرخش و غیره به‌طور کامل مورد بررسی قرار داد. مجموعه تصاویر ارسالی، باعث ایجاد نقشهٔ سه‌بعدیِ این سنگِ آسمانی‌ شد که در اوایل منظومهٔ خورشیدی شکل گرفته.

🔺 اولین تصویر بشر از این سیارک توسط رصدخانهٔ رادیوییِ Arecibo (آرِسیبو) در سال ۱۳۷۸ (۱۹۹۹ میلادی) انجام گرفت [🔗]. اما دقت و مقیاس تصویربرداری فضاپیما تا ۵ سانتی‌متر در پیکسل بود.

سرعت بازگشت فضاپیما به زمین حدود ۱۰۰۰ کیلومتر بر ساعت است که ۲.۵ سال طول خواهد کشید (۲۰ اردیبهشت ۱۴۰۰ – ۲ مهر ۱۴۰۲). در ویدئوها، مدارهای گردش به دور این سیارک نشان داده شده. —🌐— [پست قبل: 🔗]
