Dr. James L. Carter has a weird job. He manufactures fake moon dirt. His company, ETSimulants, produces tons of it every year. His primary customer is NASA, who needs fake moon dirt to test machines that might need to operate on the moon. In an interview with Pegasus News Dr. Carter explains:
"When you land on the moon, all this dry, dry dust blows into the space craft’s engines. The astronauts’ safety rests on this substance being correct. There can be no mechanical failures once you’re parked on the moon’s surface.”
I'm sure he could make some good money if he put his product in little glass bottles and sold it on eBay. After all, if eBay shoppers will buy genuine air from Loch Ness, they'll also buy fake dirt from the moon.
