[خلفية بدقة 4K] رائد فضاء بخطوط تحذير صفراء

Financial

5 ديسمبر, 2025

تُظهر الصورة توضيحًا لرائد فضاء يرتدي بدلة فضاء كاملة. رائد الفضاء هو شخص تم تدريبه خصيصًا للسفر إلى الفضاء.

يأتي مصطلح "رائد فضاء" من الكلمات اليونانية التي تعني "بحار النجوم".
يقوم رواد الفضاء بإجراء أبحاث علمية في الفضاء، وصيانة المركبات الفضائية وإصلاحها، والقيام بعمليات السير في الفضاء.
يُطلق على أفراد الطاقم الفضائي الروس اسم "رواد فضاء" (cosmonauts)، بينما يُطلق على الصينيين غالبًا اسم "رواد فضاء صينيين" (taikonauts).
يقضي رواد الفضاء وقتًا طويلاً في العمل على الأرض في التدريب والتخطيط والدعم للمهام المستقبلية.
