شاهد.. "علي القرني" يكشف عن سرعة مركبة الفضاء الدولية وسر ثباتها وعدم سقوطها على الأرض
1 سنة 0 1
صحيفة المرصد: رد رائد الفضاء على القرني على سؤال طالبة قالت فيه: "كيف المحطة الفضائية لا تطير بعيدًا في الفضاء؟".
وقال "القرني"، محطة الفضاء الدولية تطير في مدار محدد حول الأرض، على سرعة 28 ألف كيلو متر في الساعة، وهذه السرعة تعادل 28 مرة ضعف سرعة الصوت.
وتابع: في حال زيادة السرعة تبدأ المحطة ترتفع إلى مدار أعلى، ولو وصلت إلى 39 ألف كيلو متر في الساعة، سوف تطير وتخرج تماما من جاذبية الأرض، وتطير في الفضاء.
وأضاف: " العكس تماما إذا تم خفض السرعة فكلما خفضنا السرعة، كلما اقتربت من الكرة الأرضية، ويمكن أن تسقط بسبب الجاذبية الأرضية.
