U.s.-European cooperation in space science: a 25-year perspective.
In the past 25 years, the National Aeronautics and Space Administration has engaged in a range of cooperative activities in space with other countries and international organizations, most of the scientific interactions being with Europe. The character of U.S.-European cooperation in space science is changing as a result of the increased maturity and level of space capability which Europe is bringing to the partnership; the consequent addition of a competitive dimension to the relationship; the increasing cost of space science missions; and the relative scarcity of funds available for space science. A number of issues flow from the current situation, but in general the outlook is for continued productive cooperation between the United States and Europe in space science..
