Satellite Imagery in the time of COVID




I have written before about my fascination with space and space ships.  Recently SpaceX launched a ship carrying two astronauts to the International Space Station and then after that several satellites to provide better internet service.  Their plan is to launch thousands.  Even though space appears to be vast, I often wonder if its getting crowded and cluttered with space junk.

None the less, now satellites are tracking countries to determine if they are recovering as fast as they say they are from the current COVID pandemic.  Hearing about that should not have been a surprise to me but it was.  Satellites have recorded images of iconic landmarks before the pandemic started and then recent images.  You can definitely see more people out and about before, less recently which shows people were most likely sheltering in place.

Homeland security and the CDC  and anyone else who has access, can use the images to track new structures that appear. In August a site in Wuhan China was an empty parking lot but by January it was a large facility. This was an indication that the virus was spreading and affecting a mass number of people.

When the pandemic spread to the Middle East, Iran played down the number of deaths in the country, however, satellite images showed mass graves being dug that indicated something completely different.

The saying use to be You Can't Fool Mother Nature, but in this day and age you Can't Fool a Satellite. Countries should not think just because they say that the virus is under control that this will be taken as the truth. Not with SpaceX and  Satellite images available that tell a different story.
