openNASA is a collaborative blog written by NASA employees across the agency, and occasional invited guests. We come from a perspective within NASA of transparency, accessibility, risk, honesty, merit, and participation. We have insight into what is and could be happening inside the U.S. space program– but so do you, and it is something to be shared and discussed. Let’s create a space program which stimulates non-governmental activity, excitement and inspiration, and which guides humanity onto a sustainable path into the future.
