Edini na\u010din za pridobivanje podatkov o razmerah pod zemljo je bil pristanek na povr\u0161ini in za\u010detek kopanja ali vrtanja. Tovrstne metode pa so omogo\u010dale raziskovanje le do globine morda pol metra in so bile primerne le za eno samo mesto na celotnem planetu.<\/p>\n<p>MARSIS, prvi radarski sondirnik, ki je kro\u017eil okoli drugega nebesnega telesa, je dokazal, da je mogo\u010de iz orbite opazovati pod povr\u0161ino celotnega planeta.
