NASA TV coverage now is underway for the launch of a veteran Russian cosmonaut and two Japanese private citizens to the International Space Station. Roscosmos cosmonaut Alexander Misurkin joins spaceflight participants Yusaku Maezawa and Yozo Hirano on the Soyuz MS-20 spacecraft launching from the Baikonur Cosmodrome in Kazakhstan at 2:38 a.m. EST (12:38 p.m. Baikonur time). Launch and docking activities will air live on NASA Television, the NASA app, and the agency’s website. After a four-orbit, six-hour journey, the Soyuz will dock to the station’s Poisk module at 8:41 a.m. About two hours after docking, hatches between the Soyuz and the station will open and the crew members will greet each other. Once on station, the trio will join Expedition 66 Commander Anton Shkaplerov and cosmonaut Pyotr Dubrov of Roscosmos, as well as NASA astron...

Crew Keeps Up Research as Station Visitors Prep for Wednesday Launch

This view from NASA spacewalker Thomas Marshburn’s camera points downward toward the space station with the Earth 265 miles below. A Soyuz crew ship is counting down to its launch early Wednesday carrying three individuals to the International Space Station for an eleven-day visit. Back in space, the seven-member Expedition 66 crew moved along Tuesday studying space physics and biomedical science. Roscosmos cosmonaut Alexander Misurkin will lead Japanese spaceflight participants Yusaku Maezawa and Yozo Hirano aboard the Soyuz MS-20 crew ship when it lifts off from Kazakhstan at 2:38 a.m. EST (12:38 p.m. Kazakh time) on Wednesday. The trio will dock to the Poisk module at 8:41 a.m. and enter the station to greet the Expedition 66 crew about an hour-and-a-half later. Live NASA TV begins its live launch coverage on Wednesday at 2 a.m. on the agency’s  website , and the  NASA app . Onboard the orbital lab today, the station residents stayed focused on microgravity science...

Station Visitors Near Launch as Crew Stays Busy with Research

Credit: Roscosmos The Expedition 66 crew is getting ready to welcome three new visitors to the International Space Station on Wednesday. In the meantime, the seven orbital residents have started the work week on human research, space physics, and artificial intelligence. In Kazakhstan, the Soyuz MS-20 crew ship has rolled out from its processing facility and is now standing vertical at its launch pad at the Baikonur Cosmodrome. It will blast off on Wednesday at 2:38 a.m. EST (12:38 pm Kazakh time) carrying Soyuz Commander Alexander Misurkin and spaceflight participants Yusaku Maezawa and Yozo Hirano to the orbiting lab. Just over six hours later, the veteran Roscosmos cosmonaut and the two Japanese space visitors will dock to the Poisk module beginning an 11-day stay at the space station. Live NASA TV coverage of the launch begins Wednesday at 2 a.m. on the agency’s...

Station Separates from Debris After Orbital Maneuver

Image
The space station was pictured from the SpaceX Crew Dragon Endeavour during its departure on Nov. 8, 2021. View the latest photographs of the orbiting lab here. At 1:58 a.m. CST, 2:58 a.m. EST this morning, the Russian Progress 79, attached to the space station, fired its thrusters for 2 minutes and 41 seconds to slightly lower the station’s orbit. This maneuver provided a healthy margin of separation from a fragment of Pegasus rocket debris (object 39915) that ballistics specialists have been tracking. The Expedition 66 crew aboard the station is not in any additional danger. The Pre-determined Debris Avoidance Maneuver, or PDAM, was coordinated between NASA flight controllers, Russian ballistics officials, and the station’s other international partners. The station’s orbit has been lowered by 3/10 of a mile at apogee and 4/10 of a mile at perigee. The current orbit is 262.6 x 258.8 statute miles. Object 39915 was a piece of debris generated during the breakup of object 23106 (P...

Flight Controllers Assessing Debris Risk to Station

Image
The space station was pictured from the SpaceX Crew Dragon Endeavour during its departure on Nov. 8, 2021. Flight controllers and orbital debris experts in Houston are assessing the potential risk of a piece of orbital debris from a Pegasus rocket that may pass close to the International Space Station early Friday morning. Mission Control is working with NASA’s international partners to prepare for a possible debris avoidance maneuver. The closest pass is expected about 5:30 a.m. EST Friday, and the maneuver would take place about 3 a.m. if needed. The Expedition 66 crew aboard the station is not in any additional danger. Object 39915 was a piece of debris generated during the breakup of object 23106 (Pegasus R/B). The launch occurred on May 19, 1994, and the breakup of the rocket’s upper stage occurred on June 3, 1996.

NASA Astronauts Replace Antenna System Ending Spacewalk

Image
NASA spacewalker Thomas Marshburn (upper right) rides the Canadarm2 robotic arm to the worksite to replace a station antenna system. NASA astronauts  Thomas Marshburn  and  Kayla Barron concluded the first Expedition 66 spacewalk at 12:47 p.m. EST, after 6 hours and 32 minutes. Marshburn and Barron successfully installed an S-band Antenna Subassembly (SASA) on the Port-1 truss structure and stowed the failed antenna. Additionally, the pair completed get-ahead tasks on the Port-4 truss structure, including resetting the torque on a set of bolts. This was the fifth spacewalk for Marshburn, the first for Barron, and the 13th spacewalk at the International Space Station this year. Marshburn has now spent a total of 31 hours and one minute spacewalking, and Barron’s spacewalking time is now 6 hours and 32 minutes. Space station crew members have now spent a total of 64 days, 12 hours, and 26 minutes working outside the station conducting 245 spacewalks in support of a...

NASA Astronauts Begin Spacewalk to Replace Antenna System

Spacewalkers (from left) Thomas Marshburn and Kayla Barron will spend about six-and-a-half hours replacing a faulty antenna system. NASA astronauts Thomas Marshburn and Kayla Barron are reviewing the procedures they will use during Thursday’s spacewalk. The duo will exit the International Space Station after setting their U.S. spacesuits to battery power at 6:15 a.m. EST signifying the start of their spacewalk. photographed the condition of electronics gear that supports commercial spaceflight operations.
