Khi nào dùng Apollo Free-Return Trajectory 3D Explorer
Mở Apollo Free-Return Trajectory 3D Explorer khi bạn cần so sánh free-return và hybrid ở flyby Mặt Trăng - không phải công cụ thiết kế patched-conic.
Bài an toàn phi hành đoàn
Bắt đầu ở Free-return, kéo tới flyby rồi chuyển Hybrid để thấy vì sao Apollo 13 cần burn DPS-1 34.23 s sau sự cố bình oxy.
Số liệu khoảng cách Apollo 13
Ở đây có 400,171 km tại PC, ~250 km độ cao Mặt Trăng khi free-return được khôi phục, và ~2,500 nmi perigee hybrid không bắt khí quyển.
Khi trang này không phù hợp
Không dùng cho chuyển quỹ đạo Hohmann hai burn. Dùng Hohmann Transfer 3D Explorer. Điều khiển nằm trong hướng dẫn từng bước.
