SAGANet.org is a social network and community space co-founded by Sara Walker with some inspiring colleagues from Blue Marble Space. The network was created for individuals interested in astrobiology, space exploration and sustainability, where professional scientists engage the public, both through shared social spaces and targeted mentoring programs.
