Normally ending up at work on your day off is a bad thing, but today was fun. A neighbouring school (it's the Highlands, so a mere 80 miles away) had a live radio link-up with an astronaut on the ISS. Only about 15 minutes audio Q&A while the station was in line-of-sight, and plenty of static, but fun to do it the old fashioned way. (Yes, the ISS can basically do Zoom calls etc if they need to.)
