Clean Up Space Junk or Risk Real-Life Gravity Disaster

Don’t miss this important commentary about our destructive bad-waste procedures and how this all adds up to our own demise.

 

While the plot of the hit Hollywood film “Gravity” is fictional, the United States must address the alarming amount of space junk surrounding Earth, or risk potentially catastrophic collisions in orbit, lawmakers said today. Such real-life accidents could resemble the horrifying destruction depicted in the movie, they said. 

In a hearing before key members of the U.S. House of Representative’s Committee on Science, Space and Technology, experts discussed the challenges of managing the growing threat of space junk. Participants included representatives from the U.S. Department of Defense, Federal Aviation Authority (FAA) and Federal Communications Commission (FCC), along with experts in space law and space situational awareness. 

“Orbital debris, or space junk as it is sometimes called, is not science fiction. It is a growing problem,” Rep. Eddie Bernice Johnson (D-Texas) said in her opening remarks. “Dealing with the increase in orbital debris will not be easy.  

Within the Department of Defense, the Joint Functional Component Command for Space (JFCC-Space) currently tracks 23,000 objects in low-Earth orbit. NASA officials have estimated that roughly 500,000 pieces of space junk larger than a marble circle the planet, and there could be more than 100 million tiny fragments, some as small as flecks of paint, that race around Earth at blistering speeds of 17,500 mph. 

George Zamka, a former NASA astronaut and the current deputy associate administrator in the Office of Commercial Space Transportation at the FAA recalled his own harrowing experiences with orbital debris during space shuttle missions. ”During my two spaceflights, we flew upside down and backwards to prevent our space shuttle windows from being hit by debris strikes,” Zamka said. Not only have NASA space shuttles and the International Space Station had to dodge space junk over time, but two major events have added considerably to the debris problem in orbit. 

In 2007, China intentionally destroyed a defunct satellite as part of an anti-satellite test that created a vast cloud of debris. The 2009 collision between two unmanned spacecraft, one a U.S. communications satellite and the other a dead Russian satellite, created even more debris. In their testimonies, the witnesses also suggested ways that Congress might approach policies related to space traffic management. Currently, the Department of Defense oversees surveillance of space as part of its national defense duties, yet with civil agencies, private companies and commercial space travelers all potentially sharing the space environment in the near future, it may be time to re-examine the policing of this increasingly congested orbital region of space.
