An emergency supply ship is being sent from earth orbit around the sun (circular orbit around the sun with a radius of 1 AU) to Mars using a hyperbolic transfer orbit. The hyperbolic orbit has a periapsis radius R_p of 1 AU and hyperbolic excess energy of 300 km^2/s^2. Assume the ship has already escaped from earth.
The nuclear thermal rocket has a specific impulse of 900 s and thrust of 30000 N. The vehicle structural mass M_s is 1000 kg and payload mass M_L is 1000 kg.
