Is This How a Spaceship Enters Mars?

Spaceship entering mars!

okay guys so you have to open this file to read the question accuretely.. i have done some calculations but not sure if they are correct.


So just this as best as i can, fist i figure out my semi-minor axis = a
by 150km +150 KM +230 km =530km (major axis) now to get me semi minor axis i will just divide it by 2 . Giving me 265km!

Focal lenght= 265km - Earth's disntace to the sun (150 km) =115 km


Now to get my semi minor axis i use the equation b2=(a2-f2)
(530Km-300km)=b2
b=150km

Now to calculate my orbit i will use the vis-viva equation V2=GM(2/r-1/a)Where GM is the gravitational parameter of the sun and a and r are the major and minor axis of the elliptical orbit.V2 = (6.67408*10^-11)(2/150-1/265)V2 = 5.834*10^-10V = 7.625km/sNow that i have my orbital speed i can calculate the time it will take for the spaceship to enter mars. I will use this equation to do so: Time = Distance / SpeedDistance from Earth to Mars : 230Km Time= 230KM/7.625km/s Time = 30.095 minutes
