NASA is sending a remote-sensing spacecraft to Mars.
Given:
Earth parking orbit altitude= 1000 km
Mars Parking orbit altitude=Â Â 500 km
μEarth =  3.99x105km3/s2
μMars =  4.280x104km3/s2
μSun =  1.33x1011km3/s2
Earth's orbital radius =Â Â Â 1.50x108 km (assume Earth has a circular orbit for thisproblem)
Mars' orbital radius=Â Â 2.28Â Â x108 km (assume Mars has acircular orbit for this problem)
Find the semi major axis of the transfer orbit, v∞Earth , v∞Mars, ΔVboost,ΔVretro ,ΔVmission (enter your answer as a number which will be assumed to be in km)
