> The European Space Agency's Envisat satellite launched in 2002 and failed in 2012. It is the second-most hazardous object in the Top 50 list.
As a European, I would be happy if ESA planned a mission to deorbit Envisat. Besides making the orbit safer, I'm thrilled by the engineering challenge of capturing a large uncontrolled spacecraft.
There was a mission planned, but it was cancelled in 2018.
