Two Russian cosmonauts accomplished their second spacewalk collectively, putting in experiments and performing upkeep on the outside of the Worldwide House Station.
Expedition 73 commander Sergey Ryzhikov and flight engineer Alexey Zubritsky, each of the federal house company Roscosmos, had been again within the vacuum of house on Tuesday (Oct. 28) to proceed and broaden on the work they started throughout an extravehicular exercise (EVA) on Oct. 16. Throughout this most up-to-date outing, they spent 6 hours and 54 minutes mounting, relocating and cleansing {hardware} on the Nauka multipurpose laboratory module (MLM).
There they tackled their first main job of the day, attaching a two-part equipment to assist a pulse plasma (Impuls) experiment and analysis into the impact that spacecraft have on Earth’s ionosphere (IPI-500, by the NPO IT firm in Moscow). The Impuls examine will take a look at the potential for jet engines to work in house.
Between operating connectors and transferring on to the following set up, Ryzhikov additionally cleaned a window on the Nauka module. Shutters that shield the pane when it isn’t in use had been opened to permit the cleansing. When completed, the shutters had been closed once more.
Ryzhikov and Zubritsky then returned to an experiment they put in through the earlier spacewalk two weeks ago. Ekran-M, or the Molecular Beam Epitaxy experiment, is designed to produce very thin materials for use in semiconductors. After discovering a loose gasket in the device’s chamber, Ryzhikov and Zubritsky were instructed by mission control to carefully extract it using tweezers.
The spacewalkers then inserted a replacement cassette into the Ekran-M and, despite having to use wire ties to hold it in place, mission control reported getting good data. The older cassette will be returned to Earth for analysis.
Ryzhikov and Zubritsky wrapped up their time outside by relocating an exterior control panel for the European Robotic Arm (ERA), a manipulator that is used to access and service different areas of the Russian segment of the space station.
Russian EVAs often save for their final task the jettison of no-longer-needed equipment that has been gathered during the cosmonauts’ work. With the pending arrival, however, of Japan’s new robotic cargo vehicle, the HTV-X, on Wednesday morning (Oct. 29), it was decided to avoid any risk from the debris.
The spacewalk ended at 5:12 p.m. EDT (2112 GMT) with Ryzhikov and Zubritsky safely back inside the Poisk airlock.
Tuesday’s EVA was the third for Expedition 73 and the 277th in support of the International Space Station‘s assembly and maintenance since 1998. It was Zubritsky’s second spacewalk, bringing his total time outside to 13 hours and 3 minutes, and the third for Ryzhikov, who now has logged a total of 19 hours and 51 minutes in the vacuum of space.
