Cosmonauts from the Russian segment of the International Space Station (ISS) Sergey Ryzhikov and Alexey Zubritsky, who is also TASS special correspondent, have completed the installation of IPI-500 pulse plasma injectorunits on the Nauka multipurpose laboratory module (MLM) to study the impact of satellites on the Earth's ionosphere, according to a Roscosmos broadcast.

The cosmonauts will soon begin other extravehicular activities, including cleaning an MLM porthole, replacing the Ekran-M experiment's scientific equipment cassette, and transferring the EMMI external control panel to the ERA remote manipulator.
