Space Men

I spent the afternoon boggling at two astronauts from the ISS who were hanging off the outside of the station trying to find a suspected leak in the ammonia tank. This was all possible through modern technology and the NASA live feed and it was amazing. They were clipping themselves onto railings miles above earth while hurtling through the atmosphere at high speed. And brandishing screw drivers. Gripping stuff.
They are both now safely back on board. Phew.
