Last weekend, I (Andreas) was part of the NASA Space Apps Challange 2017. It is the biggest global hackathon with more than 180 locations and more than 20,000 participants.

The theme was "Earth Observation" and the participants worked to combine space data from NASA with their very own solution to create something incredible helping solve global problems. I was part of the Team "Tunnel God Detector" to detect and locate tremors to support emergency respond teams and thus saving people in danger.

Why I write this is easy: I provided the time synchronization method of my Distributed Ground Station Network and we improved it for the Tunnel-God-Sensors a lot by just discussing it in crazy ways that are just possible during hackathons like these.

I had so much fun and met awesome people! I want to say thank you to all of you. And I want to invite everyone to keep on working on the project even after SpaceApps. For that, it is on hackaday now >> https://hackaday.io/project/21788-tunnel-god-detector
