European Space Agency astronaut Samantha Cristoforetti became the initial European female spacewalker on July 21, when she completed a seven-hour spacewalk outside the International Space Station alongside Russian cosmonaut Oleg Artemyev.
The function was also the very first time in nearly 25 years that any European participated in a Russian-operated spacewalk. The duo spent 7 hours and five minutes configuring a fresh robotic arm for the Russian segment of the area station, and deploying several small satellites.

Cristoforetti, shown here with fellow European Space Agency astronaut Alexander Gerst during training, used the Russian-made Orlan spacesuit during her July 21 excursion. Unlike NASA’s Extravehicular Mobility Unit spacesuit, Orlans are made to be utilized in space without return to the bottom for servicing.
Typical disposal methods for old Orlans include putting them happening cargo spacecraft to naturally burn in the atmosphere, or jettisoning the used gear overboard.
Orlan suits use two variants of stripes on the spacesuits, to tell apart spacewalkers from one another. The lead spacewalker, Russian cosmonaut Oleg Artemyev, is merely visible to the proper of the image above in red stripes. Cristoforetti, in center of the view, is shown with blue stripes.
Spacewalks are usually broadcast instantly to mission controllers in both Moscow and NASA, allowing ground support to aid the spacesuited crew by considering just what the crew is considering, instantly.
Since Cristoforetti was employed in microgravity, this allowed her to orient her body in the manner that was easiest to reach the gear externally of the Russian segment. All astronauts like Cristoforetti must train in ground facilities simulating the area station, like the Neutral Buoyancy Laboratory at NASA’s Johnson Space Center in Houston.
The laboratory includes a huge pool which has a group of modules much like those of the ISS, allowing crews to apply the very best handholds because of their tasks and to discover ways to maneuver in microgravity. Each spacewalk’s tasks is rehearsed to attempt to be sure that everything could be accomplished with time, as spacesuit resources when it comes to water, oxygen and power are limited.
Cristoforetti (top) worked closely with Artemyev (bottom) on several spacewalk tasks. The duo mounted a temporary platform which will be used by the brand new European Robotic Arm (ERA). The arm was installed on a youthful spacewalk, but requires multiple excursions to configure.
The 37-foot-long (11-m) ERA will more equipment and scientific round the Russian segment of the area station. It isn’t the initial ISS robotic arm; for instance, the Canadian Canadarm2 robotic arm and japan Kibo robotic arm are veterans in assisting the area station’s mandate of conducting research and performing maintenance.
Apart from focusing on the arm, Artemyev (left) and Cristoforetti come up with a payload adapter for the Nauka module. This adapter is intended to become a support for tools and payloads for crews doing Russian-segment spacewalks later on.
Another of the tasks saw Artemyev configure an external control panel, called the External Man Machine Interface. Eventually, that interface will let future spacewalkers manipulate the arm beyond your space station. No other robotic arm on the station could be controlled from the exterior, making the European Robotic Arm unique in this capability.
Working amid spectacular views of the planet earth and of the area station, Cristoforetti and her Russian colleague also centered on releasing 10 nanosatellites yourself. These little machines formed a radio technology experiment and were named after Konstantin Tsiolkovsky, a Soviet-era rocket pioneer.
“I start to see the Earth and deploy happening,” Artemyev said while releasing the initial of the satellites, through English-language interpretation supplied by the spacewalk broadcast on NASA Television. “There it goes.”
While ground teams did their finest to schedule tasks that could easily fit into well with the projected seven-hour spacewalk timeline, the spacewalkers were delayed in exiting the hatch by about 40 minutes. Moscow therefore elected to postpone among the major tasks to some other time.
The crew was likely to extend a Strela telescoping boom between your Zarya service module and the Poisk research module, an activity that was designed to make future spacewalks easier. Ground control called off the duty, however: “We have been terminating due to the spacesuit life support system constraints,” Russian mission control radioed to the spacewalkers.
The spacewalkers next closed out their tasks and made their solution to the Poisk airlock, closing the hatch at 5: 55 p.m. EDT (2155 GMT) and concluding the spacewalk. It had been the sixth career spacewalk for Artemyev and in addition marked the sixth ISS spacewalk overall for 2022 up to now.
Overall, the ISS has already established 251 spacewalks supporting the assembly, upgrade and maintenance of the orbiting facility since 1998. While Cristoforetti was the initial European to don an Orlan at the ISS, three ESA astronauts did so before at the former Soviet-Russian Mir space station: Jean-Loup Chrtien, Thomas Reiter and Jean-Pierre Haigner.
Cristoforetti, seen here beaming in her Orlan spacesuit cooling garment, conveyed her because of all of the support teams in a Twitter message on July 28, 2022.
“Just two words: MANY THANKS! Many thanks all in Europe, Moscow, Houston and @Space_Station,” she wrote. “Thanks for attempting to get this to possible, thanks for working out, the look, the real-time support, the videos and pictures, the trust and the encouragement. It had been a dream become a reality.”
