“We needed to identify a strategy in between controlled and uncontrolled reentry, taking maximum benefit from satellite capabilities. The polar orbit of Aeolus offers the possibility to target some ground tracks with little landmass and very few inhabitants. In particular, a corridor...
Further, the Earth's orbit around the Sun is not circular, but oval or elliptical (see Figure 4 ). An elliptical orbit causes the Earth's distance from the Sun to vary over a year. Yet, this phenomenon is not responsible for the Earth's seasons! This variation in the distance from ...
