We no longer expect that! Originally scheduled in 2007, the European arm of ERA would launch today. The ERA, along with the Columbus Science Laboratory and the Automated Transfer Vehicle (ATV), is the third major component of European participation in the International Space Station programme. It is installed on the new Russian Nauka module, also known as the Russian Multipurpose Laboratory (MLM) module, and will be assigned to the Russian part of the station, many parts of which are inaccessible by the Canardarm2 boom.
an armESA’s ERA, integrated into Russia’s Nauka module, will be launched on July 21 for ل (ISS). Very late in its initial schedule – it was supposed to launch in 2007 – this arm was built by a European consortium led by Airbus Defense and Space. era dedicated to The Plus the Canadarm2 robotic arm that can’t reach all of this part of the International Space Station.
Naoka is a small space station. Although designed for piloting and a living and working area for astronauts, this unit will also serve as a docking port. It also has the peculiarity of being equipped with the CNG navigation and guidance control system in addition to the position control system. It could be used as a backup by the International Space Station and if the Russians decide to separate the Russian part of the International Space Station, as they expected, Nauka could be the heart of their future space station. The Nauka will be installed on the Zvzeda unit, instead of the Pirs unit, which will be separated from the Russian segment. Pirs was used as an additional docking port forand as a smuggler for Russian cosmonauts into space. It will be absorbed by progression.
Supplementary arm for Canadarm2
Although very different from Canardam2, ERA will be a complement. It is 11.30 meters tall and weighs 680 kilograms, and it can moveVery large, from three tons in routine to eight tons in slow mode. This two-handed symmetrical arm can move forward or backward under its control along the International Space Station, from hand to hand, from one fixed point to another. the seven Strong and delicate, limbs are light and The mid-arm control gives the robotic arm its versatility. It will be used to install and replace solar panels, inspect and assemble modules, and facilitate the movement of solar panels. Do a space walk. Finally, his cameras To inspect the outer surface of the station (aging of protective coatings, traces and check attachments to modules, platforms, etc.).
ERA can be controlled from inside or outside the station, in real time or pre-programmed. With its joints, the ERA looks like a kind of human arm. It is powered by motors and cables. It is symmetrical, on both sides of the “elbow” there are “muscles” and “two wrists”. Its ends are able to stick to the terminal, which gives it a large range of motion throughout the Russian part. It will move installation from one end and then the other. Finally, it was equipped with many tools, including a platform with toe clips and a handrail to transport astronauts during their spacewalk. Among the main strengths of this arm:
- Control from the outside using an external control panel;
- Control from the inside using a laptop (without the need for like the other arms of the International Space Station);
- Pre-programmed operation
- Automated collision avoidance system based on a ;
- 5 mm accuracy.
European astronauts maneuvering
The first electrical examination of the ERA will be conducted. , which is due to join the station in early November, should participate in a spacewalk to validate the operation in the orbit of the ERA arm. Later, ESA astronaut Samantha Cristoforetti, who will carry out a new mission aboard the International Space Station at the end of 2022 (Crew 4), will also perform during a spacewalk, one of the ERA stabilization missions for Nauka.
The European robotic arm awaits the departure of the International Space Station

The launch of Russia’s Nauka Multifunctional Laboratory (MLM), scheduled for 2007, has been delayed several times and has just been pushed back to 2013. It will be equipped with the European Space Agency’s long-ready Era robotic arm. Years. Philip Schönigans, Era Project Manager, explains to Futura-Sciences the custom functions of this beautiful mechanism… which you eagerly await.
The Russian announcement was to postpone the launch of a missile The Era robotic arm has been operational for a long time »., which should be attached epoch (European robotic arm), once again forced the ESA to patiently put up with its problems. As Philip Schoneghans (Era Project Director) stated in Futura-Sciences, “
This arm is one of the three main contributions of European participation infrom . This program was officially launched in November 1995 and its construction was completed at the end of 2004. Since 2008, it is located in Russia. At first, the program planned to launch by a space shuttle, then due to circumstances, a decision was made to send it in November 2007 on board With the MLM unit. Since then, the launch has been delayed several times to finally be set on December 10, 2013.
Having set her new schedule, nWe will prepare Era according to the new launch date Concretely, integration into the Russian unit is now planned for August 2013 and the whole, i.e. Nauka supported era, will soon be moved to the site or Kazakhstan.
For Philip Schönigans, that’s The relay has no effect on the arm itself It is currently stored in Conditions that prevent any deterioration that may damage its componentsلاف “.However, this postponement will result in additional cost because some industrial activities” over a longer period We can cite for example those relating to Software compliance for Nauka unit computers », in preparation for launch or even that of ensuring that the Era arm qualifies for a shipment by Russian” While it was originally qualified to launch on a US space shuttle ».
The Russian part of the International Space Station needs an era
Despite his late arrival aboard the International Space Station, Era’s arm must” We expect sustainable activity because the robotic arm ». , provided by Canada, does not cover the entire Russian part of
Upon arrival, Era will be used as a priority to complete Nauka’s setup. if he” You will install heat sink panels for “, The most common from loneliness and airlock equipment to exit in order to reduce crew space exits. The Era arm is designed to work with the Russian airlock, so that ” Astronauts no longer have to venture outside the space station to assemble certain bits of material. Using video cameras, the arm can conduct checks outside the station, can transport experiments and supplies, or even act as a lift for astronauts. ».
Finally, he will install the work platform on which the crew members will sit. This hook is at the end of the arm and” Astronauts are allowed to sit in a standing position for work or transportation All these items are already on board the International Space Station, stored in the Russian module الوحدة (MRM-1).
