“The only way to [solve this problem] is to bring back the larger objects,” NASA scientist Donald Kessler, who has led NASA’s Orbital Debris Program Office for nearly 20 years, told The Huffington Post in 2013.
But if we’re going to do anything about this problem, then we better do it fast, Kessler said earlier this year.
“We’re at what we call a ‘critical density’ — where there are enough large objects in space that they will collide with one another and create small debris faster than it can be removed,” Kessler told Marketplace in September.
