Perhaps you should try some spelling variations:
"french geodetic mission" » "french robotic mission", "french poetic mission", "french genetics mission"
"free geodetic mission" » "free robotic mission", "from geodetic mission", "free genetic mission", "edge geodetic mission"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"french geodetic mission\") OR (\"free geodetic mission\"))".
• Removing quotes may allow a broader search: (( french geodetic mission ) OR ( free geodetic mission )).
• Adding a wildcard symbol may retrieve word variants: (("french geodetic mission") OR ("free geodetic mission"))*.
