The ISS said goodbye to the Russian Pirs module and sent it off to turn into a streaking fireball.

The Russian-built Pirs docking module and a Progress spacecraft (with the extended solar panels) undocked from the ISS on its way to burning up in the atmosphere.

European Space Agency astronaut and ISS crew member Thomas Pesquet captured views of the Pirs module farewell process from undocking to when it turned into a streaking fireball. .

The Pirs Docking Compartment (known as DC-1) acted as an airlock for spacewalking cosmonauts and a docking port for spacecraft.

The images give a good look at the module and the Russian Progress spacecraft attached to it just after the pair undocked.

The fireball in the center of the picture is the Pirs docking compartment and Progress spacecraft burning up.

The non-combustible structural elements of the #ProgressMS16 cargo ship and the #Pirs module fell in a non-navigable area of the Pacific Ocean.
