QUESTION:
I would like, if it is possible, to get some 
information about the possibilities to study (if there are any) at NASA (or 
wherever the education is situated).

ANSWER from Duncan Atchison on October 9, 1997:
Thanks for your questions about student opportunities in the space
program. Here are a few sources to check out:
http://astrobiology.arc.nasa.gov/academy/index.html

This site describes not only our recent program started here in
California, but the others across the country.

Also read the brochure and description of the Space Life Sciences
Training Program.
http://www.famu.edu/copps/slstp/index.html

Although both of these programs are primarily geared to US students,
because you are an exceptionally qualified student, if may be worth your
while to write to the program managers to see if there is flexibility in
the admissions process.
