The Million Dollar... Pen?
To paraphrase an old joke: When presented with the challenge of writing in a zero-gravity environment, the United States and the Soviet Union approached the same problem in two different ways. NASA spent millions of dollars developing and testing the space pen. The Russians, on the other hand, used a pencil.
In reality, the space pen wasn't developed by NASA, but rather a private company that later sold its invention to both the U.S. and the U.S.S.R.
A kernel of truth is hidden in this story, however. NASA originally used mechanical pencils and hired a private contractor to supply "34 units" at a price of $4,382.50 in 1965 (around $30,000 today). The public outcry against this purchase led NASA to the cheaper alternative designed by Fisher Space.
