Mysterious symbols in the desert captured by international space station cameras: “you never know what you might see”
A camera affixed to the International Space Station recently spotted some curious symbols in a barren desert in Tunisia.

“This caught our attention,” Charles Black, claimed the founder of live streaming company Sen speaking to Mashable recently.
Recent footage captured by Sen shows what appears to be huge “mysterious writing etched into the sand,” the company explained.

The symbols are an example of the type of phenomena, natural and human-created as revealed by the camera as the space station, located some 250 miles above Earth.
These letter-like patterns are in fact from agriculture activity, vividly contrasted by the barren desert plains in Tunisia, Black explained.
“We want the audience to be engaged,” Black said. “It’s promoting debate, discussion, and interest. We’ll label the location, but we want the viewers to decide, discuss, and make comments.”
The space station orbits Earth about 16 times a day, and during each orbit the floating laboratory shifts a little to the west. “Whenever you log on to Sen, you can see something different,” Black said. “You never know what you might see.”
