This paper proposes to discuss space research cooperation between France and the United States as it existed at the beginning of the 1960s.Among NASA's missions, when created in 1958, was to conduct a policy of international cooperation. Great Britain and Canada responded rapidly to the NASA's proposals.With France, however, the situation was quite different. At that time, Paris wanted to develop large scale space research activities of its own.For this purpose, in January 1959, the French government created the “Comite´ des Recherches Spatiales”, which had two missions: to organize the space research in France and to participate in international space affairs. Although French research at that time was sufficiently advanced in sounding rockets and military missiles to develop a program whose objective was to create a national launcher, France's scientists did not really have enough experience in satellite design, unlike most other countries involved in space research during this period.At this time, several cooperative programs were initiated between France and the United States, in fields such as rocket experiments, visual observation satellites and satellites tracking. However, the first major cooperative program between the two countries concerned the development of a scientific satellite—later known as FR-1— which was launched in December 1965.

The Mars Sample Return (MSR) Project is underway. A 2003 mission to be launched on a Delta III Class vehicle and a 2005 mission launched on an Ariane 5 will culminate in carefully selected Mars samples arriving on Earth in 2008. NASA is the lead agency and will provide the Mars landed elements, namely, landers, rovers, and Mars ascent vehicles (MAVs). The French Space Agency CNES is the largest international partner and will provide for the joint NASA/CNES 2005 Mission the Ariane 5 launch and the Earth Return Mars Orbiter that will capture the sample canisters from the Mars parking orbits the MAVs place them in. The sample canisters will be returned to Earth aboard the CNES Orbiter in the Earth Entry Vehicles provided by NASA. Other national space agencies are also expected to participate in substantial roles. Italy is planning to provide a drill that will operate from the Landers to provide subsurface samples. Other experiments in addition to the MSR payload will also be carried on the Landers. This paper will present the current status of the design of the MSR missions and flight articles., (c 2000 American Institute of Aeronautics and Astronautics, Inc. Published by Elsevier Science Ltd.)
