Russian EVA 54; Roscosmos cosmonaut Oleg Artemyev and ESA astronaut Samantha Cristoforetti will work outside the ISS for more than six hours.
On July 21, a Russian-European spacewalk will take place at 14:00 UTC, Roscosmos cosmonaut/ Expedition-67 Commander Oleg Artemyev and European Space Agency astronaut/ Flight Engineer Samantha Cristoforetti will work outside the Russian sections of the International Space Station for more than 6.5 hours. The spacewalking duo will deploy ten nanosatellites designed to collect radio electronics data during the EVA, and put in place a telescopic boom in place from Zarya to Poisk to assist in future spacewalks.
Both astronauts will be wearing Orlan spacesuits, with Oleg wearing red stripes and Samantha wearing blue stripes. Sergei Korsakov will provide support to the spacewalkers before they exit the Space Station through the space-facing Poisk module.
For Oleg Artemyev, this will be the sixth spacewalk (and the third for this expedition), and for Samantha Cristoforetti - the first (and first in the Russian "Orlan").
Working on European Robotic Arm
This will be the third spacewalk to include tasks around getting the European Robotic Arm(ERA) ready for its first operations on Nauka MLM. The astronauts will move their external control panel, work on insulation and install a temporary adapter point for the robotic arm.
Samantha will spend some time making sure a window shield on the arm’s camera unit is clear enough to allow laser light to guide the arm for grappling and moving around.
They will continue preparing the ERA manipulator for operation and will launch a dozen small spacecraft - two Tsiolkovsky-Ryazan satellites and eight YuZGU-55 satellites, created by Russian students.
10 satellites of the YUZGU-55 series will go into outer space. This will be a record number of small spacecraft launched during one exit.
The devices will perform the following tasks:
Measure the Earth's magnetic field;
Investigate the Kursk and Brazilian magnetic anomalies;
Practice active stabilization systems based on magnetorquer
Broadcast to radio amateurs plans, voice shots of SSTV, and greetings in eight languages of the world.
According to the publication "City News" from Kursk, the devices were developed by scientists of the local South-Western State University. Satellites have already been delivered to the ISS.
