The Planetary Society's mission is to encourage the exploration of the solar system and the search for extraterrestrial life. This means being a voice of popular expression in support of government programs in planetary exploration. We encourage your participation because it is the only way we can prove that planetary exploration is worth the cost of government support. It is also the principal reason that the Society must maintain a large membership base.
Size is key when trying to have influence with government programs.
We have lobbied or championed the cause of planetary exploration with decision makers in many countries, including the United States, Canada, England, France, Australia and Russia. The Planetary Society publishes position statements, letters, and news releases. Lobbying is a small part of our overall activity, but still an important one. It is financed strictly by individual member dues and donations, and does not include industry or government support. The Planetary Society urges everyone interested in the future of space exploration to contact their elected officials for support of strong exploration programs.
