Japan's troubled 'space junk' mission fails

An experimental Japanese mission to clear 'space junk' or rubbish from the Earth's orbit has ended in failure, officials said Monday, in an embarassment for Tokyo. Over 100 million pieces of garbage are thought to be whizzing around the planet, including cast-off equipment from old satellites and bits of rocket, which experts say could pose risks for future space exploration. Scientists at the Japan Aerospace Exploration Agency (JAXA) were trying to test an electrodynamic 'tether' -- created with the help of a fishing net company -- to slow down the orbiting rubbish and bring it into a lower orbit.
