Imaging Space Debris In High Resolution

Litter is not only a problem on Earth. According to NASA, there are currently millions of pieces of space junk in the range of altitudes from 200 to 2,000 kilometers above the Earth's surface, which is known as low Earth orbit (LEO).

Using Cubesats To Reduce Space Junk

"Engineers at the University of Glasgow and Clyde Space Ltd have developed a practical solution to the increasing problem of space debris. Millions of pieces of 'space junk' are orbiting the Earth as a side-effect of human exploration and exploitation of space. The pieces range from tiny fragments of bigger objects such as rocket boosters to full-sized pieces of now-defunct equipment. Working satellites and spacecraft can be damaged by collisions with debris, which can travel at velocities of several kilometres per second. The problem is compounded by every collision which creates more debris in turn; in 2009, the collision of a non-operational Russian communications satellite and a working US satellite created more than 700 pieces of debris. Dr Patrick Harkness of the University's School of Engineering has led the development of the Aerodynamic End Of Life Deorbit System, or AEOLDOS, to help ensure that objects sent into space in future can be removed from orbit at the end of their operational cycle."

Tracking Objects in Space

To continue successfully keeping track of objects in orbit around Earth, the U.S. Air Force should become more open and transparent in the creation and dissemination of its algorithms, processes, and research in astrodynamics, according to a new report from the National Research Council.
