This week-end is the big NASA SpaceApps hackathon!
Everyone is welcome - you don't need to be a coder, being passionnate about space exploration is the only requirement. If you don't know what a hackathon really is, think of it as a marathon but for programmers, a week-end of intensive coding.
The goal is to make a project over a week-end, with all the materials that NASA will provide us. It can be a mobile application, web app, game, video, presentation, or even a physical project like a robot - anything that can address the challenges. These challenges are well-documented with a problematic to solve. It may be a good idea to select your challenge of choice  before the event and eventually put it on our pad :
