When we visit legislators or staff members in Congress we always provide them with a "leave-behind" to reinforce our position.
This tends to be a one page summary of our reason for visiting, which right now is about stopping the proposed cuts to NASA's Planetary Science Division in next year's budget.
It's a dense page, since there's a lot to talk about, but I'm pretty happy with it. Please download (1.2 MB PDF) and share this with family, friends, or even your local representatives. It's a high-resolution PDF, and it will look great when printed by a quality color printer.
If you have any questions about individual points, don't hesitate to ask!
