Richard Hayler and his children spoke at the Big Birthday Weekend about their AstroPi project – how it was developed and the story of how their code ended up in Space! Their experiment, which uses the SenseHAT’s built-in humidity sensor to detect the presence of an astronaut and then takes a picture, has begun to record data, and that data is now back on Earth. You can download the data and photographs yourself from Github and you can read the Haylers’ story on Richard’s blog, along with some analysis of the data.
