NASA will provide coverage of the upcoming prelaunch and launch activities for the Imaging X-ray Polarimetry Explorer (IXPE) mission, the first satellite dedicated to measuring the polarization of X-rays from a variety of cosmic sources, such as black holes and neutron stars.
NASA Sets Live Launch Coverage for Laser Communications Demonstration
NASA is taking a step toward the next era of space communications with the launch of its Laser Communications Relay Demonstration (LCRD) on Sunday, Dec. 5.
NASA Teams Delay Spacewalk After Debris Notification
NASA astronauts Thomas Marshburn and Kayla Barron were slated to perform a spacewalk to replace a faulty antenna system.
The evening of Monday, Nov. 29, NASA received a debris notification for the International Space Station. Due to the lack of opportunity to properly assess the risk it could pose to the astronauts, teams have decided to delay the spacewalk planned for Tuesday, Nov. 30 until more information is available. The space station schedule and operations are able to easily accommodate the delay of the spacewalk. The latest information and future spacewalk dates will be shared on https://blogs.nasa.gov/spacestation.
NASA astronauts Thomas Marshburn and Kayla Barron will go on a spacewalk on Tuesday for station maintenance work.
NASA astronauts Thomas Marshburn and Kayla Barron are scheduled to exit the International Space Station’s Quest airlock Tuesday for a spacewalk that will focus on replacing an S-band Antenna Subassembly (SASA) with a spare already available on the station’s truss structure.
Live coverage of the spacewalk will air on NASA Television, the agency’s website, and the NASA app beginning Nov. 30 at 5:30 a.m. EST, with the crew members scheduled to set their spacesuits to battery power about 7:10 a.m., signifying the start of their spacewalk.
Marshburn and Barron will work at the Port 1 (P1) truss structure, where the antenna is mounted. The antenna recently lost its ability to send signals to Earth via NASA’s Tracking and Data Relay Satellite System. Although its degradation has had limited impact on station operations, mission managers decided to install a new antenna to ensure communications redundancy. The space station has additional low-rate S-band systems, as well as the high-rate KU-band communications system that relays video.
During the planned six-and-a-half hour spacewalk, Marshburn will position himself at the end of the Canadarm2 robotic arm, working in tandem with Barron. Astronaut Matthias Maurer of ESA (European Space Agency) will control the robotic arm from inside the space station.
This will be the 245th spacewalk in support of space station assembly. Marshburn will be extravehicular crew member 1 (EV 1), with red stripes on his spacesuit, while Barron will be extravehicular crew member 2 (EV 2), with an unmarked suit.
This will be the fifth spacewalk for Marshburn, the first spacewalk for Barron, and the 13th spacewalk on the space station this year. The pair arrived for a six-month science mission at the space station Nov. 11 with NASA’s SpaceX Crew-3 mission aboard the Crew Dragon Endurance.
