(retrograde motion) for about 80 days every two years. Mars is retrograde 9% of the time, which is very low compared to the other superior planets, which average about 38% and even Mercury at 19%. This rarity is one reason Mars is the most challenging planet when retrograde. We are ...
As the flight is mostly unpowered and lasts a long time, the tiny inaccuracies in position and velocity will gradually accumulate, and cause the probe to miss the red planet if not corrected. Therefore, a control strategy for mid-course orbital correction is indispensable, as it sets ...
