Explanation:
Orbital debris from spacecraft, the defunct satellites and fragments of spent rockets left suspended in Earth's atmosphere, are slowly making their way back to Earth. Objects usually return after a few years, but debris trapped in higher orbits can remain for more than a century.
Purdue University's David Spencer, associate professor of aeronautics and astronautics, aims to develop a system that in the future would deorbit spacecraft launched by companies like SpaceX, OneWeb, and Boeing, as the spacecraft complete their missions. A space junk animation is available here.
Why is this important? "There are a number of high-value orbits that have become so populated with defunct satellites and debris spacecraft that they're approaching a tipping point," Spencer said. "Once that tipping point is reached, a cascade of uncontrolled collisions can occur, rendering the orbit unusable. And into the mix the thousands of satellites that companies plan to launch into orbit in the next several years, and the problem becomes much worse."
