This weeks segment looks at what space technology research can also teach us about the earth.

Transcript:

Our obsession with outer space is helping us understand our Earthly environment.

This is the Iowa Environmental Focus.

The recently unveiled, first-ever photograph of a black hole captured imaginations. The black hole–now christened “Powehi” –was actually photographed in April 2017, but the image was just released this year. Taking the image required eight telescopes from around the world.

Telescopes, satellites, and other space-age technology have helped us explore the far reaches of our solar system–and have given us a way to truly analyze and map our climate from above.

The data collected from orbiting satellites has helped climate scientists for decades. Satellite data helped us discover the hole in our ozone layer in 1985. Some satellites are specifically launched to monitor ice caps, track sea levels, and measure the amount of CO2 in our atmosphere. 

Many tools used for monitoring our climate today are modeled after space technology, and the research and development of tools that help us leave our atmosphere will also help us understand our planet.
