Astronaut Watches Russian Space Station Module Fall From Space In Fiery Demise

On Monday, astronauts said goodbye to a cornerstone of the International Space Station and captured stunning images of the compartment burning up in Earth's atmosphere. Space.com reports: A Russian Progress cargo vehicle towed the module, called Pirs, away from the space station and down through Earth's atmosphere to ensure the module burned up completely and reduce the odds of any large chunks making it to Earth's surface. Russia had launched its Pirs module in 2001; since then, the module, which served as a port to the space station, hosted more than 70 different capsules and supported Russian cosmonauts conducting extravehicular activities, or spacewalks. To make room for Russia's new science module, dubbed Nauka, which launched on July 21 and will arrive at the station on Thursday (July 29), Pirs had to go. Yesterday's fiery retirement ceremony marks the first time a major component of the International Space Station has been discarded. The attached Progress vehicle, which had arrived at the space station in February, controlled Pirs' re-entry to ensure that the module was destroyed as thoroughly as possible. European Space Agency astronaut Thomas Pesquet shared the photographs on Flickr.
