Space Debris: A Growing Concern

Space Debris: A Growing Concern to Astronauts in SpaceA significant issue for the future is our total lack of care for the planet on which we live. We not only have the problem of plastic waste and carbon dioxide emissions, but now we have the issue of space debris.

From 1957 when the space age began, until January of 2019, humans have placed nearly 9,000 satellites in Earth orbit. More than half of them, around 5,000, are still in orbit, and 1,950 are still functioning. In addition to the satellites, there is debris from all this activity. The European Space Agency tells us that there are 130,000,000 pieces of debris larger than .04 inches in orbit around Earth. The number of articles between .4 inches and 4 inches is 900,000, and 34,000 are 4 inches or larger.

What all of this space debris does to Earth’s neighborhood is becoming a concern to scientists. It creates a danger of collision with operating satellites or crewed spacecraft, such as the International Space Station. That danger becomes especially apparent when you realize that space debris can be traveling at speeds up to 17,500 miles per hour (28,100 km/hr). The threat obviously increases as we continue to orbit objects of all kinds, leaving more junk in space.

Why is it that we have to have a tragedy to make us realize the importance of being good stewards of what God has created for us? God gave us the responsibility to take care of the Earth, and He has not rescinded that duty as we develop new technology.
