**Sending a spacecraft to mArs! Help! pLease!**

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
