The Future of U.S. Planetary Exploration

As the millennium closed, so did the era of large-scale planetary spacecraft. Future planetary spacecraft will increase their capability, as compared to their predecessors, while reducing in size and consuming less power. These future spacecraft will be the landers and sample return missions of tomorrow.

Lander and sample return missions require innovative mission concepts, new operation approaches, as well as technologies that have yet to be developed. In addition, these missions will be more numerous then in the past. Rather than one mission every decade, every decade will have numerous missions.

To organize this effort, the United States robotic planetary exploration program has been divided into five areas:

  1. Earth Exploration
  2. Mars Exploration
  3. Outer Planet Exploration
  4. Asteroid & Comet Exploration
  5. Universe

This presentation will describe each of these areas, the major missions currently in operations and those being planned. It will also have a special emphasis on extra-solar planet searches and the search for life.
