I have already attemped this problem and got an angular momentum magniude of 1.20315389e+15 m^{2}kg/s but i dont know if it is right. By the way the position vectors of the spacecraft are in meters and the velocity vectors are in m/s. Also, its the angular momentum that is required to finish calculating the eccentricity and not the angular momentum vector components right?
