The second spacewalk within the "ISS-73" expedition is scheduled for Sergey Ryzhikov and Alexey Zubritsky, today, October 28, at 17:19 Moscow time. The Russian cosmonauts in outer space will conduct the "Impulse" experiment, which involves installing impulse plasma injector units on the "Nauka" module to study the impact of satellites on the Earth's ionosphere from the ISS.
According to Roscosmos, the opening of the exit hatch of the "Poisk" module will take place at 17:19 Moscow time. The estimated duration of the extravehicular activity is 6 hours 28 minutes. The previous spacewalk lasting 6 hours 11 minutes 12 seconds was performed by Ryzhikov and Zubritsky on October 16.
In addition to the installation of the impulse plasma injector, the Russian cosmonauts will also have to clean the porthole of the hermetic adapter of the Nauka multipurpose laboratory module, replace the scientific equipment cassette for molecular beam epitaxy — a grown crystalline material on a special substrate (the "Ekran-M" experiment), and also transfer the external control panel EMMI of the ERA remote manipulator.
It is possible that the first grown films of semiconductor crystals will be obtained already now.
The plasma injector is one of the two blocks of the "IPI-500" scientific equipment complex, which also includes a special unit for controlling the electrophysical parameters developed by "NPO IT", developed by order of the Rocket and Space Corporation "Energia" named after S.P. Korolev. The planned long-term experiment will be carried out on the Nauka multipurpose laboratory module of the Russian segment of the ISS. During the service life of the ISS, scientists will be able to turn on the equipment at the right time and at the right point in orbit to study the ionosphere during various space events, such as magnetic storms or solar activity.
For Sergey Ryzhikov, the spacewalk will be the third in his career, for Alexey Zubritsky — the second. Ryzhikov will perform extravehicular activity in the commander's Orlan-MKS No. 7 spacesuit with red stripes, and Zubritsky — in the Orlan-MKS No. 6 spacesuit with blue stripes. Yesterday, under the supervision of ground specialists, Alexey checked and adjusted the spacesuit system.
The guests of the live broadcast will be Maxim Zaitsev, leading test engineer of RSC Energia; Olga Lapshinova, leading engineer of the department for ensuring the implementation of research of the Scientific and Technical Center of Useful Load of RSC Energia; Alexander Bogaty, Deputy Director of the Research Institute of Applied Mechanics and Electrodynamics of MAI.
