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. If the transfer orbit has a semi-major axis of 195100000 km, how long, in days, would the interplanetary trip last? Hint: first, determine the period of the transfer orbit. Mars @ arrival Fig. 1.
