The Kessler Syndrome remains an vapormax reduction ever-present threat.
More than 5,000 launches since the start of the space age, each carrying satellites for Earth observation, or communications, for example, have resulted in space becoming increasingly congested and contested.Tracking systems, objects as small as 3mm can be detected by ground-based radars.Image copyright nasa Image caption Astronauts aboard the ISS shelter in the Soyuz capsule when a piece of junk is detected too late to manoeuvre.Image copyright US AIR force / Bennie J Davis III Image caption The US has a network of sensors, such as this.67m telescope in Hawaii, to track satellites and debris.This is no easy task, however, requiring new technologies, potentially new laws and - crucially - financial investment.Against the background of an increasing space junk problem, a renaissance is now taking place in space; what was the principal domain of governments and space agencies, with their large, multi-billion dollar satellites, is becoming the province of an emerging industry that is revolutionising the.Travel up to speeds of 28,163 km/h (17,500 mph).Space junk in numbers, image copyright nasa Image caption In 2007, a chunk of space debris punched this hole in the radiator panel of space shuttle Endeavour 500,000 pieces of space debris between 1 and 10cm.Small satellites: the future?The problem also threatens crucial and costly satellites in orbit.The space age has enabled global solutions to some of society's biggest challenges, just as Ernst Stuhlinger described in his letter to Sister Mary Jucunda.

The greatest concentrations of debris are found at 750-800km.
In particular, these concerns focus on the abrupt increase in the number of satellites orbiting the Earth, which could substantially increase the need for collision avoidance manoeuvres and hasten the onset of the Kessler Syndrome.

Now, the US Space Surveillance Network is tracking tens of thousands of objects larger than a tennis ball orbiting above us, and we suspect that there are one hundred million objects larger than 1mm in the environment.
Sadly, the space environment has borne the brunt of our increasing reliance on satellites and our long-lived belief that "space is big".
