Astro Pi 2: New Raspberry Pi hardware with updated camera, sensors to head to the ISS this year

Good news for earthbound Pi-tinkerers hoping to get their code into orbit: a follow-up to 2015's Astro Pi is due to head to the International Space Station (ISS) this year. Time has moved on a bit since the Principia mission of Tim Peake where the first units were installed aboard the orbiting outpost. While over 54,000 participants from 26 countries have since had code run on the hardware, the kit has fallen somewhat behind what is available on Earth. To that end, some new units are due to be launched, replete with updated hardware. In this case, heading to orbit will be Raspberry Pi 4 Model B units with 8GB RAM, the Raspberry Pi High Quality Camera (a 12.3MP device) and the usual complement of gyroscope, accelerometer, magnetometer, humidity, temperature and pressure sensors for users to code against.
