SpaceX, 2019\u2019dan bu yana yeniden kullan\u0131labilir roketleriyle 8 binden fazla uyduyu y\u00f6r\u00fcngeye yerle\u015ftirdi. Sadece 2025 y\u0131l\u0131nda bu say\u0131ya 2 binden fazla yeni uydu eklendi. \u015eirketin rakipleri de benzer ad\u0131mlar at\u0131yor: Amazon, kendi uydu internet a\u011f\u0131 Project Kuiper i\u00e7in 3 bin 200 uydu f\u0131rlatma plan\u0131n\u0131 ba\u015flatt\u0131.<\/p>\n
