How Do You Calculate the Semi-Minor Axis for a Spacecraft's Orbit?

In summary, the conversation is about sending a spacecraft to Mars and the person is asking for help with their calculations. They have calculated the semi-minor axis to be 265km and the focal length to be 115km by using the equation b2=(a2-f2). They also mention a file with diagrams and hints.

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

Hello, it seems like you are trying to calculate the semi-minor axis and focal length for your spacecraft's orbit around Mars. It's great that you are doing some calculations, but it's important to make sure that they are accurate. In order to get the correct values, you need to use the correct units for the distances. For example, instead of using kilometers, you should use meters. Also, make sure that you are using the correct values for the Earth's distance to the Sun and Mars's distance to the Sun. These values can be found from reliable sources such as NASA's website. Additionally, there are specific equations that should be used for calculating orbital parameters, so make sure you are using the correct one for your specific situation. It's always a good idea to double check your calculations and consult with other experts in the field to ensure accuracy. Good luck with your mission to Mars!
