It literally took until Kepler to understand the elliptical nature of planetary motion to develop an ephemeris that is even close to being "reasonably accurate" for significant lengths of time.
kepler's model was the most accurate (still pretty good today, right?), but which would you say is more accurate between copernicus and ptolemy? neither system worked with the degree of accuracy we require. but is one more right than the other, just because it has the right idea? or is it because the explanation is a little simpler?
Most likely, you couldn't. Ptolemaic astromony is a linear system and going to Mars requires some understanding of relativistic physics because you are going fast enough to have it show some effects. We've already seen a probe bounce off the atmosphere because of errors in approach.
yes, i suppose that was exageration. nasa and russians both had lots of problems sending stuff to mars.
although, the most recent error in approach was due to a stupid programmer using the wrong system of measure.
You prove my point.
wasn't trying to do otherwise.
Most think it's a rock outcropping.
as someone who appreciates geology, that's a pretty cool outcropping.
(personally, it's just never looked like a big boat to me)
