Spacebridge: The Next Generation

Space: the final frontier. These are the voyages of the hackerspace Noisebridge, our ongoing mission to explore strange (yet economically priced) new ascent technologies; to seek out new parts and new partnerships; to boldly go where no non-government-or-massively-industrially-funded-group has gone before. Discussions: Discord Project Thread - To be included in Spacebridge-related announcements go to #bot-commands and type /rank Spacing Guild. Weekly meetup notes EVENTS: We have weekly meetings Sunday at 5pm-7/8ish. (Meetup page) Spacebridge interest list Launch and field trip announcements will be made during the weekly meeting as well as the #announcement channel on discord.
