2.9 Mir/DOS-7 (February 19, 1986-present)The Mir space station is the centerpiece of the Russian manned space program. Its base block (figure 2-11) has been in orbit for 9 years. Continual modifications have more than tripled Mir’s original mass and increased its capabilities (figure 2-12) beyond those of any previous space station. |
