I think that the problem is that you should define a custom version of
SerializeElements helper.
If you go into afxtempl.h (at least in VC2008, I'm not sure about VC2005,
but I think it is the same...), you will read that:

  void AFXAPI SerializeElements(CArchive& ar, TYPE* pElements, INT_PTR
nCount)

this generic template form of SerializeElements does just a bit-wise
serialization. This is good for "primitive" types like int or doubles, but
it fails for more complex types like CString (which stores *pointers*).

So, I think you should write a customized version (template specialization)
of SerializeElements for your particular class CPlanetAspect, i.e. you
should write the body of this template specialization:

template<> void AFXAPI
SerializeElements<CPlanetAspect> (CArchive& ar, CPlanetAspect * pElements,
INT_PTR nCount);

and take care of proper CString serialization.
