It’s been nearly 50 years since man first walked on the moon. Sometimes we ask ourselves what it was all for other than the obvious bragging rights.

Afterward, a lot of nifty consumer items were introduced as a result of developments for the space program.
No more having to put a glass stick under your tongue (or anywhere else for that matter) and keep it there for several minutes just to take your temperature. The ear thermometer works in two seconds because of a heat sensor that was originally developed to measure the infrared temperatures of distant stars.
