Two Russian cosmonauts spent six hours outside the International Space Station on Thursday (June 22) cleaning up the exterior of the orbiting laboratory by removing and tossing overboard a trio of no longer needed devices, including a spent science experiment.
Expedition 69 commander Sergey Prokopyev and flight engineer Dmitry Petelin, both of Russia's federal space corporation Roscosmos, exited the space station's Poisk module at 10:24 a.m. EDT (1424 GMT) on Thursday.
In addition to jettisoning hardware, the spacewalk also included the installation of a new stanchion for high-speed telemetry equipment and the retrieval of a micrometeoroid impact experiment that had been mounted outside the space station for a number of years.
Prokopyev and Petelin made quick work of rerouting cables and disconnecting a data relay unit and a telemetry transmitter, as well as the hardware for a completed experiment that measured seismic activity on Earth, before throwing each overboard for their eventual disposal, burning up in Earth's atmosphere.
