Every monument needs protection and cleaning from time to time. The Sciencenter has a great program to not only enable the Sagan Planet Walk to be inspected, protected, and cleaned on a regular basis, the program also enables community organizations to take ownership of this wonderful memorial.
Every month members of different community organizations walks the Planet Walk cleaning and inspecting each of the monuments. The walk is a nice distance and doesn't take a lot of people to do.
If you and your group are interesting in helping keep the Sagan Planet Walk in top shape please contact the Sciencenter for details.
