Because beyond being probably one of the coolest project on the planet, SETI is a necessary undertaking for all of us, and if I can help at my ant scale...
What are your views about the project?
I'd be proud if I were part of it and I don't do enough for it.
SETI@home and Astropulse are funded by grants from the National Science Foundation, NASA, and donations from SETI@home volunteers. AstroPulse is funded in part by the NSF through grant AST-0307956.
