On 10 March 2006, after seven months in space, NASA’s Mars Reconnaissance Orbiter fired its six main engines for 27 minutes. Inzira% s Bya Igihe Nyuma, Inyuma Bya Umuntu: Oya ku. i Byanze, i na i.

3. Science orbit. After hundreds of passes over about five months, MRO reached a low, nearly circular orbit about 250 by 316 km up, and could start mapping Mars.

Gusobanukirwa

Coming from Earth on a Hohmann-like path, the spacecraft reaches Mars about 2.65 km/s slower than Mars. Akadomo Bya ni “Umuvuduko Ku”, v∞. Falling to 426 km above the surface, it speeds up to

v = √(v∞² + 2μ/r) = √(2.65² + 2 × 42,828 / 3,822) ≈ 5.4 km/s

On an ellipse from 426 km to 44,500 km, the speed at the low point must be 4.56 km/s (vis-viva). The ideal, instantaneous capture burn is therefore about 0.87 km/s. A real 27-minute burn is less efficient because it is spread along the curve; MRO’s slowed the spacecraft by about 1 km/s.
