Reid experiments with a compass - Windows on Earth

Reid experiments with a compass


Oct 19, 2014


This is a fascinating video clip.


ISS astronaut Reid Wiseman attached a compass to his computer screen, and then made a 2 hour long movie (here condensed to 2 mintues) showing one orbit (and a bit).  The map shows the orbital path, as the ISS icon moves along.


This is a bit of a challenge.  We'll even call this a good one for the space geeks. What is going on?  What makes the compass slowly rotate one way then another?


We'll give you a hint - the compass is VERTICAL.  The bottom of the compass points down to the Earth, the top of the compass points up.
