Recall that your trip to Mars is accomplished by using an elliptic transfer orbit going from Earth to Mars as shown in Fig. 1. This trajectory assumes that Earth at departure, the Sun, and Mars at arrival, are aligned. Also, we will assume that Earth's and Mars' orbits are circular, with radiuses R = 147284000 km and 228888000 km, respectively. What is the eccentricity, e, of the orbit?
