re: Learning
I've sung this tune before but I'll sing again: ISS can be accused of being overbudget, inefficient and badly managed but a complete waste it is not. Plenty of interesting science aside from the effects of weightlessness on humans is done there, hopefully it will be kept going to do a lot more. This link is a good place read about the experiments being done there:

There's lots of criticism that can be justifiably leveled against it, but there's a lot positive that can and is being done with the place.
