On Jan 27 astronauts Hopkins and Glover performed spacewalk US EVA-69 using spacesuitsEMU 3006 and 3009. SAFER backpacks 13 and 18 were also used.The Quest airlock was depressurized by about 1118 UTC and the hatch was opened at 1126 UTC,with the astronauts putting the suits on battery power 2 min later. The first major taskwas to install the ColKa antenna on the outside of ESA's Columbus module. ColKa, builtby MDA/Harwell in England, provides high bandwidth Ka-band science data download. TheColKa package was launched on the Cygnus NG-13 mission in Feb 2020 and has been storedinside ISS since then. The package has a mass of 105 kg plus a 15 kg removable cover.Glover mounted the Canadarm-2 at ESP-2 and carried ColKa to Columbus, installing itat 1242 UTC and completing bolting it down by 1316 UTC. Next the astronauts routed cablesto ColKa and to the Bartomoleo platform. (Unfortunately, one Bartomoleo cable could not beconnected and was left tied down for a future EVA.) The ColKA cover was removed at 1529 UTCand jettisoned into space by Glover at 1600 UTC. The cover was cataloged as S47513,1998-067RY in a 417 x 421 km orbit. The astronauts then retrieved equipmentfrom the airlock and moved to the P6 truss to remove two H-fixture bolts from the solar arraymast there. The astronauts returned to the airlock, ingressing at 1813 UTC and closing thehatch at 1820 UTC. Quest was repressurized at 1824 UTC.
