The crew of the International Space Station pays a special tribute to the European Space Agency’s fourth Automated Transfer Vehicle (ATV-4), known as the “Albert Einstein”, which undocked from the ISS earlier.

Besides carrying supplies to the ISS, the “Albert Einstein” was also used to boost the International Space Station into a higher orbit. Saturday it will plunge to a destructive re-entry over the Pacific Ocean with a load of trash.
