I was talking to a friend of mine and we somehow got on the topic of the space program, space shuttles, space station, etc...... He commented that NASA and the space program ought to be cut and shelved permanently. It's not the first time I've heard this argument. Usually it centers around the idea that we're spending all this money in space when we should focus on our problems here at home. This guy had a completely different argument though. He argued that we should scrap the space program because we're not getting any useful knowledge out of it. Sure we learn more about how the universe works and how to do things in zero gravity, but that knowledge is useless he argued because it's just knowledge. It's not stuff that's useful here on Earth and it's not stuff that's commercializable in most cases. It's just knowledge. And knowledge for the sake of knowledge and science just for the sake of discovery is pointless. My face at that point kind of looked like a three year old who's sucker has just been stolen by a bully. Has our respect for science in our society really sunken this low?
