NASA astronauts Mike Hopkins and Victor Glover concluded their spacewalk at 1:24 p.m. EST, after 6 hours and 56 minutes. The two NASA astronauts completed a number of tasks designed to upgrade International Space Station systems.

The crew installed a Ka-band antenna, known as COL-Ka, on the outside of the ESA (European Space Agency) Columbus module, which will enable an independent, high-bandwidth communication link to European ground stations. Bartolomeo is partially operational and in a safe configuration following the connection of four of six cables to the science platform, and the final two cables that could not be connected will be attended to on a future spacewalk.

During the spacewalk, Hopkins and Glover also removed a pair of grapple fixture brackets on the far port (left) truss in preparation for future power system upgrades. Glover also worked to replace a suspected broken pin inside the station’s airlock as a “get ahead” task, but teams determined that a replacement pin was not needed after an inspection confirmed the current pin to be functioning properly.

Space station crew members have conducted 233 spacewalks in support of assembly and maintenance of the orbiting laboratory. Spacewalkers have now spent a total of 61 days, 1 hours, and 47 minutes working outside the station.

Hopkins has now completed his third spacewalk for total of 19 hours and 54 minutes outside the space station. This was the first spacewalk for Glover with a total of 6 hours and 56 minutes.

On Feb. 1, Hopkins and Glover will conduct another spacewalk to address a variety of tasks, including installation of a final lithium-ion battery adapter plate on the port 4 (P4) truss that will wrap up battery replacement work begun in January 2017. Hopkins and Glover will remove another grapple fixture bracket on the same truss segment, replace an external camera on the starboard truss, install a new high-definition camera on the Destiny laboratory, and replace components for the Japanese robotic arm’s camera system outside the Kibo module.

Station Wraps Busy Week Before Cygnus Cargo Mission Launches

Image
This high exposure photograph from the International Space Station shows Earth’s atmospheric glow and a starry sky as the orbital complex soared above the Pacific Ocean. The Expedition 70 crew is looking ahead to the arrival of a U.S. cargo craft due to arrive at the International Space Station next week. Meanwhile, the Axiom Space 3 (Ax-3) crew finished its first week in orbit with a busy schedule of research, education, and media activities. Northrop Grumman’s Cygnus cargo craft will take its first ride atop a SpaceX Falcon 9 rocket when it lifts off at 12:29 p.m. EST on Monday from Kennedy Space Center in Florida. The private space freighter will be carrying over 8,200 pounds of science experiments, crew supplies, and lab hardware to the orbiting outpost. NASA Flight Engineer Jasmin Moghbeli is due to capture Cygnus with the Canadarm 2 robotic arm at 3:35 a.m. on Wednesday. She will be on duty that morning along with fellow NASA astronaut Loral O’Hara who will monitor Cygn...

NASA and Sierra Space are making progress on the first flight of the company’s Dream Chaser spacecraft to the International Space Station. The uncrewed cargo spaceplane is planned to launch its demonstration mission in 2024 to the orbital complex as part of NASA’s commercial resupply services. Credit: Sierra Space/Shay Saldana NASA and Sierra Space are preparing for the first flight of the company’s Dream Chaser spacecraft to the International Space Station. Dream Chaser and its companion cargo module, called Shooting Star, arrived at NASA’s Neil Armstrong Test Facility in Sandusky, Ohio, for environmental testing, scheduled to start in mid-December, ahead of its first flight, scheduled for the first half of 2024. The Neil Armstrong Test Facility, part of NASA’s Glenn Research Center in Cleveland, is home to multiple test facilities, including the Space Environments Complex and the In-Space Propulsion Facility, both stops for Dream Chaser. The complex is home to the Mechanical Vib...

Crew Dragon Suit Checks as Station Begins Orbital Reboosts

Image
This long-exposure photograph from the space station reveals the Milky Way glittering above a bright but exaggerated atmospheric glow blanketing the Earth’s horizon. The Expedition 63 crew checked out SpaceX Crew Dragon suits today and stayed busy with a full slate of space research. The International Space Station also completed the first of three orbital reboosts to get ready for the next crew mission in October. Flight Engineers Doug Hurley and Bob Behnken inspected the suits they will wear when they return to Earth aboard the Crew Dragon spaceship. The duo tried on their suits for a fit check and ensured the components are in good condition. They are scheduled to depart the station on Saturday and splashdown the following day. NASA TV will cover all the departure activities live. The homebound-duo started the day replacing environmental control system (ECS) hardware aboard the orbiting lab. That work required temporarily removing a plant habitat from the Unity module to...
