Melting a piece of a satellite Researchers took one of the heaviest, bulkiest parts of an Earth-orbiting satellite, placed it in a plasma wind tunnel, then proceeded to melt it into vapour. Their goal was to better understand how satellites burn up during reentry, to minimise the risk of endangering anyone on the ground. Taking place as part of our Clean Space initiative, the fiery testing occurred inside a plasma wind tunnel, reproducing reentry conditions, at the DLR German Aerospace Center’s site in Cologne.
Planetary collisions simulated by supercomputer Planetary impacts were simulated using the COSMA supercomputer at Durham University to study its effects on atmospheres. Credit: Dr Jacob Kegerreis, Durham University / mash mix by Space.com's [Steve Spaleta](http://www.twitter.com/stevespaleta)
