The Citizens for Space Exploration mission is to promote awareness of the benefits of human space exploration and support for NASA and the US Space Exploration Policy.

Citizens is a multi-state organization comprised of U.S. taxpayers who support America's investment in space exploration. We are private citizens, small business owners, students, teachers, space and non-space business representatives, and county and municipal officials.

Citizens (formerly known as National Keep It Sold) was formed in 1992 through the efforts of the Bay Area Houston Economic Partnership (TX), the Cocoa Beach Area Chamber of Commerce (FL), the Huntsville/Madison County Chamber of Commerce (AL), and the Partners for Stennis (MS and LA).

Representatives from Citizens for Space Exploration travel to Washington, D.C. annually to meet with members and staff to discuss the benefits of space exploration. These benefits include:

• Improving the overall quality of life for our citizens and the world in areas such as medical research and health care.
• Advancing America's scientific, technological, security and economic interests.
• Inspiring a new generation of explorers to pursue technical careers based on science, math, computers and engineering.
• Promoting U.S. leadership and competitiveness while providing opportunities for international cooperation.

Citizens also communicates with elected officials through regular newsletters and special legislative messages. In 2005, Citizens for Space Exploration formed an alliance partnership with the Coalition for Space Exploration in support of the Vision.
