Unformatted text preview: 3 /s 2 . PROBLEM 3 (Sec. 7.3): The specific impulse of a spacecraft is 350 seconds. The ΔV required for transfer from the parking orbit to the mission orbit is 1.2 km/s. The initial mass of the spacecraft is 980 kg. Calculate the propellant mass required for this phase of the mission. NOTE: The relationship between the three masses shown above Equation 7.14 in the book must be corrected to: m f = m- m p where m f is the spacecraft final mass, m is the spacecraft initial mass, and m p is the propellant mass....
