‘Hundreds’ of impacts found on ESA’s Columbus module

Each International Space Station module is designed with micrometeoroid debris protection. A recent survey of the European Space Agency’s Columbus module shows just how much it is needed.

According to a news release from ESA, a survey performed Sept. 6, 2018, using the station’s 17.6-meter robotic arm showed “hundreds of impacts” across the surface of the Columbus module.

Spacewalking astronauts finish Canadarm2 work at breakneck speed

Spacewalking astronauts finish Canadarm2 work at breakneck speed

Two astronauts—one American, the other Japanese—suited up to venture outside the International Space Station to finish work upgrading the outpost’s robotic Canadarm2, a process that has now involved five extravehicular activities over some four months.

The six-hour U.S. EVA-48 began when NASA astronaut Mark Vande Hei and Japan Aerospace Exploration Agency astronaut Norishige Kanai put on their suits and exited the Quest airlock.

Software patch fixes Canadarm2 anomaly, US EVA-48 postponed

Software patch fixes Canadarm2 anomaly, US EVA-48 postponed

NASA has postponed its planned Jan. 29, 2018, spacewalk to swap a latching end effector on the International Space Station’s robotic Canadarm2 after robotics specialists devised a software patch to fix a communications anomaly with the recently-installed mechanism.

While an exact date has not been set, the agency said it is targeting mid-February for the rescheduled outing.

NASA reports problem with newly installed Robotic arm 'hand'

Just days after installing a new grapple fixture on the International Space Station’s robotic Canadarm2, NASA is working on a plan to re-install the old latching end effector on an upcoming spacewalk after a problem was found with the new mechanism.

U.S. EVA-28 was already planned for Monday, Jan. 29, 2018, less than a week after the previous spacewalk installed the new LEE.

Astronauts replace Canadarm2 ‘hand’ on ISS in first spacewalk of 2018

Astronauts replace Canadarm2 ‘hand’ on ISS in first spacewalk of 2018

The first spacewalk of 2018, U.S. EVA-47, is now in the history books after two NASA astronauts completed a nearly 7.5 hour extravehicular activity to replace an aging latching end effector on the International Space Station’s robotic Canadarm2.

Canadarm2 has a latching end effector, also called a LEE, on either side of the 17-meter robotic arm to either grab onto the exterior of the station, move objects around the outpost, or grab visiting spacecraft.

Astronauts breeze through US EVA-45

Astronauts breeze through US EVA-45

Less than a week after completing one spacewalk, International Space Station Expedition 53 astronauts Randy Bresnik and Mark Vande Hei set out on another extravehicular activity. This excursion, U.S. EVA-45, lasted about 6.5 hours.

At 7:56 a.m. EDT (11:56 GMT) Oct. 10, 2017, the two NASA astronauts switched their spacesuits over to battery power, officially starting U.S. EVA-45. The primary task of the spacewalk was to replace a faulty camera and begin the process of lubricating the new Latching End Effector on the robotic Canadarm2.
