Two spacewalkers at the International Space Station (ISS) activated the facility’s new robotic arm for the first time on Thursday, April 28.
Russian cosmonauts Oleg Artemyev and Denis Matveev concluded their spacewalk at 6:40 p.m. ET after 7 hours and 42 minutes outside the ISS, with much of that time spent working on the European Robotic Arm (ERA).
The ERA arrived at the station in July last year but it remained covered with thermal blankets until Thursday.
NASA shared footage (below) of the two cosmonauts some 250 miles above Earth as they worked to release the robotic arm from its restraints ahead of its first workout.
Getting to this stage has been a long time coming. The ERA was designed more than 30 years ago, and various technical issues over the last 20 years caused it to miss three planned missions to the ISS.
But now European Space Agency (ESA) engineers can finally celebrate the arm’s first activation in space.
The new robotic arm is about 11 meters long, weighs 1,390 pounds (630 kilograms), and includes seven joints that offer a high degree of maneuverability.
