[spazzie]

In the not too distant future the first American astronaut prepares to set foot on the planet Mars. The world is watching this event live on television. Everything is a success, or so the world thinks, and he is treated as a hero upon his return. Later, it is discovered that the mission was a failure and as the astronaut was on Mars he died of an undetermined condition either due to toxic poisoning due to conditions on Mars or some unknown bacteria native to Mars.
