"It's dangerous, and shameful for anybody including the US that has allowed space debris to be up there."For ShameAccording to NASA administrator Bill Nelson, the issue of space junk is about to become a lot more relevant as we spend more and more time in Earths orbit and, he admitted, its partially the fault of the United States.Its dangerous, and shameful for anybody including the US that has allowed space debris to be up there, Nelson told CNN in an interview on Tuesday.In fact, with companies including Amazon and SpaceX hoping to launch tens of thousands of satellites into low-Earth orbit, the issue could be about to get much worse, despite promises these satellites would end up harmlessly burning up in the atmosphere once retired.Space DisgraceThe US isnt the only contributor to the problem of space junk. Nelson cited a Chinese government test that involved intentionally blowing up a satellite, generating thousands of pieces of space debris at around 150 to 350 miles up, within the range of the International Space Station.China is making major strides in space exploration, recently becoming only the second nation to softly land a rover on Mars and in the process setting the stage for the next space race.When asked if were in for another space race, Nelson replied I hope not. But it is clear that China is developing very sophisticated space capabilities.The US would benefit far more if it were to work with China. We also want to cooperate on managing space debris, because that junk is lethal.The risks are very real.If it hits something like our space station or an astronaut during a spacewalk, it would puncture the spacesuit, Nelson told CNN. That would be instant death.READ MORE: NASAs new chief on SpaceXs Mars rocket, UFOs and going back to the moon [CNN]More on space junk:Space Debris Blasts Hole in Space Stations Robotic ArmAs a Futurism reader, we invite you join the Singularity Global Community, our parent companys forum to discuss futuristic science & technology with like-minded people from all over the world.
