Two astronauts working outside the International Space Station Wednesday installed a European Space Agency data relay antenna and connected four of six cables to partially power a new ESA experiment platform. They also removed two solar array handling fixtures to clear the way for a future power system upgrade.<\/p>\n

But the two cables they were unable to connect to the Bartolomeo platform, attached to the front side of ESA\u2019s Columbus laboratory module, will need to be connected later to accommodate a full suite of external payloads.<\/p>\n

\u201cAt least we got partially connected to Bartolomeo,\u201d European astronaut Andreas Mogensen radioed the crew from mission control in Houston.<\/p>\n

Floating in the Quest airlock, astronauts Mike Hopkins and Victor Glover switched their suits to battery power at 6:28 a.m. EST to officially kick off 233rd spacewalk in station history and the first so far this year. It was the third spacewalk for Hopkins and the first for Glover.<\/p>\n

After floating out of the airlock, Glover attached a foot restraint to the end of the space station\u2019s robot arm and rode the space crane to the European Space Agency\u2019s Columbus module where he and Hopkins installed a high-speed Ka-band data relay antenna.<\/p>\n

Flight controllers initially had problems activating a heater in the antenna, but after Hopkins unplugged and re-connected a power cable, the system began working normally.<\/p>\n

The spacewalkers then worked to route cables and to connect the Bartolomeo experiment platform to the Columbus module, providing power and data relay to experiment and instrument attachment points<\/p>\n

Bartolomeo was delivered to the station last spring aboard a SpaceX cargo ship and attached to Columbus using the robot arm. The platform will be used to mount a variety of external experiment packages that can be changed out as needed for research.<\/p>\n

\u201cWe have been preparing for the better part of a year as we awaited the arrival of the Bartolomeo platform,\u201d said flight director Rick Henfling. \u201cIt arrived on the SpaceX CRS-20 (cargo) mission last April. It was installed robotically, and now we have a few more tasks, using our spacewalkers to hook up the power and data connections.\u201d<\/p>\n

But Hopkins and Glover were only able to get four of six cables properly connected. While Hopkins worked to resolve the problem, Glover, still riding on the end of the robot arm, carried a protective cover that had been attached to the new antenna to a point well away from the main body of the station.<\/p>\n

Once in position, seeming to float alone in orbital darkness, Glover pushed the boxy antenna cover away on a trajectory that ensured it would not make its way back to the station\u2019s vicinity before re-entering the atmosphere and burning up.<\/p>\n

Unable to resolve the cable trouble, Hopkins capped the two balky connectors and used tie-downs to hold all the cables in place.<\/p>\n

Both spacewalkers then made their way to the far left end of the station\u2019s power truss and removed two solar array ground handling fixtures. The so-called \u201cH fixtures\u201d are being taken off to make way for new solar panels that will be attached to the existing arrays later to boost the lab\u2019s power output.<\/p>\n

Today\u2019s spacewalk came to an end at 1:24 p.m. after six hours and 56 minutes.<\/p>\n

Hopkins and Glover plan to carry out a second spacewalk next week to remove additional H fixtures, to complete work to install a replacement solar array battery and to replace cameras on the power truss, the Destiny lab module and on a Japanese robot arm.<\/p>\n

\u201cWe\u2019ve been talking about this particular set of EVAs for the better part of a year,\u201d said Kenny Todd, space station integration manager at the Johnson Space Center. \u201cSo I\u2019m certainly ready to be done talking about them and actually go see them executed.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
