18. They Managed To Elude NASA
China’s cold weather coupled with rising air pollution has caused a major smog problem in the country. With rapid industrialisation to blame, the air is heavy and dense with toxic pollutants and irritants that are causing respiratory problems amongst citizens.
What does this have to do with NASA?
NASA’s satellites are constantly monitoring and geo-mapping the world’s topography, recording real-time data. Everything that goes on in different cities, towns, villages can be captured through these satellites.
Smog in China became so thick that it covered entire regions causing NASA satellites to lose visibility over them, shrouding them from external eyes.
