14 space agencies walk into a bar... Okay, no joke.  The ISECG Initiative (I added 'Initiative' because it sounds more sci-fi) is an attempt to basically let individuals at different science institutes share information.  Given the strength of Intellipedia and perhaps even Wikipedia, it seems info sharing might be the way to go.

The 14 agencies are:
ASI (Italy), CNES (France), CNSA (China), CSA (Canada), CSIRO (Australia), DLR (Germany), ESA (European Space Agency), ISRO (India), JAXA (Japan), KARI (Republic of Korea), NASA (United States of America), NSAU (Ukraine), Roscosmos (Russia), UKSA (United Kingdom)
I like info sharing, and I like their earlier work at producing mission timelines for long-term (25 years+) mission efforts like 'go to an asteroid' or 'get back to the effing moon.'  If you fold this into the 'space punk' efforts of folks like Interorbital or Copenhagen Suborbital, we may actually get somewhere.
