+
+The C3Space Assembly is intended as place to hang out (and to show of projects)
+for everyone interested in space exploration, space travel, satellites, cubesats,
+satellite tracking, diy astronomy, amateur rocketry ... you name it.
+The goal is to bring all the different people hacking on space topics in our community in one place,
+explore existing projects and come up with new ideas to hack where no congress has hacked before.
+
+As is tradition by now we teamed up with the [Libre Space Foundation](https://libre.space/)
+to create an awesome assembly for all things space related.
+
+Please be aware, that we aim to provide a safe environment for all galactic life forms
+(although we are only able to provide an oxygen atmosphere). We come in peace!
+
+**Location:** **TBD**
+
+Topics
+======
+* Building a satellite
+* How to receive and decode signals from space
+    * Weather satellites: APT, HRPT, ...
+    * Cubesats
+    * DIY radio astronomy
+    * The (SatNOGs Project)[https://satnogs.org/]
+* General rocket science
+* Model/Experimental rockets
+* DIY rocket engines
+* Nerding real rocket science
+* History of space flight and exploration
+
+Projects
