NASA is going to launch a rocket to Mars, with the rocket blasting off from the Earth when the Earth and Mars are aligned along a straight line from the Sun. If the Mars is now 60° ahead of the Earth in its orbit around the sun, when should they launch the rocket? All the planets orbit the sun in the same direction and 1 year on Mars is 1.9 Earth-years. Assume circular orbits for the Earth and the Mars.
