TBD - spacewalk (ISS U.S. EVA-94) from Quest airlock (ModKit 8 iROSA Prep 3B)
TBD - spacewalk (ISS U.S. EVA) from Quest airlock (Install iROSA 2A on the P4 truss segment)
TBD - spacewalk (ISS U.S. EVA) from Quest airlock (Install iROSA 3B on the S6 truss segment)
TBD - spacewalk (ISS U.S. EVA) from Quest airlock (replace the S1 pump)
TBD - spacewalk (ISS U.S. EVA) from Quest airlock (replace the S1 pump)
TBD - spacewalk (ISS U.S. EVA) from Quest airlock (replace the S1 pump)
TBD - spacewalk (ISS U.S. EVA) from Quest airlock (replace the P1 pump)
TBD - spacewalk (ISS U.S. EVA) from Quest airlock (replace the P1 pump)
TBD - spacewalk (ISS U.S. EVA) from Quest airlock (replace the P1 pump)


Not to mention the EVAs to upgrade the AMS-2, for which Fincke and Kim trained.

What's happening with the EMUs?
We have no information from NASA.
As for the first 3 ModKit 8 was delayed by the damaged Cygnus during transport and the pair of IROSA's were a additional order so they were in manufacturing and are awaiting an available Dragon flight with VV schedule a factor. The SpaceX Dragon propulsion risk reduction demonstration payload bumped all external upmass payloads by a flight. As for the latter six these are contingency EVA's that are in planning to replace the ammonia pumps with yet to be used on orbit spares to maintain their functionality as the the current ones are original to the truss segments and are nearing their certified life expiration dates and are showing some slight degradation. Once degradation reaches a certain threshold limit they will change them out.

MOSCOW, November 19. /TASS/. The International Space Station’s (ISS) orbit was raised by 2.7 km to create ballistic conditions for the arrival of the Soyuz MS-28 spacecraft and the departure of the Soyuz MS-27 spacecraft, Russia’s state-run space corporation Roscosmos said.

"The orbit of the International Space Station has been adjusted [by] 2.7 km," the state corporation said in a statement.

Thrusters of the Progress MS-32 space freighter were turned on at 4:04 a.m. Moscow time, and fired for 847.47 seconds, producing an impulse of 1.55 meters per second.

"The average altitude of the ISS orbit is 419.74 km above the Earth’s surface," Roscosmos added.

The current ISS crew comprises Russian cosmonauts Alexey Zubritsky (TASS special correspondent aboard the ISS), Sergey Ryzhikov and Oleg Platonov; NASA astronauts Jonny Kim, Zena Cardman and Michael Fincke, and JAXA astronaut Kimiya Yui.

NASA is moving up the Crew-12 launch date from March 27 to February 15. Here's why, according to a statement from the space agency:

Quote
NASA and SpaceX have been working to be ready as early as Feb. 15 for the next commercial crew rotation launch to the International Space Station. This change maximizes launch opportunities for NASA's SpaceX Crew-12, while also accommodating the Artemis II launch windows. As both missions advance toward launch and rely on resources and facilities at NASA's Kennedy Space Center, this change helps deconflict operations.

JEM RMS is retrieving something from the JEM Airlock slide table - presumably the i-SEEP 3 payload that went inside a few days ago. (I can't tell from this camera angle whether or not it's still in its flight support equipment.)
Robotics operations overnight - JEM RMS installed i-SEEP 3 onto EFU-12.
JEM RMS stowed the Small Fine Arm, so i-SEEP 3B is probably staying put for a while.

I looked around to see if I could find a reference to what experiment(s) were installed on it - no joy.

Discussion thread for SpaceX's 34th Commercial Resupply mission (SpX CRS-34).

Launch TBD 2025 at TBD UTC from KSC LC-39A or CCSFS SLC-40.  Cargo Dragon C2XX-X launched by Falcon 9 first stage 1XXX-X.  First stage is targeting recovery at LZ-2 (could be at SLC-40 or LC-39A landing sites if they are completed before launch).

The last set of iROSA (2A/3B) should be the external payload for this mission.

This mission was awarded as part of a 6 mission contract extension to the CRS2 contract in March 2022 covering missions through CRS-35 in 2026.

Quote
The 12 additional missions ordered – six each to Northrop Grumman and SpaceX – will provide resupply services to the station through 2026.

NASA, Boeing Modify Commercial Crew Contract [Nov 24]

Quote
In 2014, NASA awarded a Commercial Crew Transportation Capability contract to Boeing to fly astronauts to and from the International Space Station with its Starliner spacecraft. As part of its contract, Boeing was awarded up to six crewed flights to the orbital complex.

After a thorough evaluation, NASA and Boeing have mutually agreed to modify the contract. As part of the modification, the definitive order has been adjusted to four missions, with the remaining two available as options. The next Starliner flight, known as Starliner-1, will be used by NASA to deliver necessary cargo to the orbital laboratory and allow in-flight validation of the system upgrades implemented following the Crew Flight Test mission last year.  NASA and Boeing are targeting no earlier than April 2026 to fly the uncrewed Starliner-1 pending completion of rigorous test, certification, and mission readiness activities.  Following Starliner certification, and a successful Starliner-1 mission, Starliner will fly up to three crew rotations to the International Space Station.

“NASA and Boeing are continuing to rigorously test the Starliner propulsion system in preparation for two potential flights next year,” said Steve Stich, manager of NASA’s Commercial Crew Program. “This modification allows NASA and Boeing to focus on safely certifying the system in 2026, execute Starliner’s first crew rotation when ready, and align our ongoing flight planning for future Starliner missions based on station’s operational needs through 2030.”

Certification of Boeing’s Starliner remains important to NASA’s goal of sustained human presence in low Earth orbit and dissimilar redundancy is essential to supporting the agency’s goals and international obligations.

Northrop Grumman’s Cygnus XL cargo spacecraft, supporting the company’s 23rd commercial resupply mission to the International Space Station for NASA, will be uninstalled from the Earth-facing port of the space station’s Unity module on Monday, Nov. 24. The cargo spacecraft will remain attached to the station’s Canadarm2 robotic arm until Monday, Dec. 1, clearing the way for the arrival of the crewed Roscosmos Soyuz MS-28 spacecraft on Thursday, Nov. 27.

NASA, Northrop Grumman, and Roscosmos coordinated the spacecraft’s movement to prevent any unnecessary structural loads from being imparted on Cygnus XL and its solar arrays when the Soyuz spacecraft docks to the Rassvet module, which is the adjacent docking port. The maneuver will be conducted by the robotics officer in Mission Control Center at NASA’s Johnson Space Center in Houston, while agency astronauts Jonny Kim and Zena Cardman monitor from inside the orbital complex.

Cygnus XL will be reattached to the space station Dec. 1, and will remain there until no earlier than March 2026, when it is scheduled to depart and dispose of several thousand pounds of trash during its destructive re-entry into Earth’s atmosphere.

Expedition 74 crewmembers: NASA astronaut Chris Williams, Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergey Mikaev are scheduled to launch aboard their Soyuz MS-28 spacecraft on November 27.

A Soyuz rocket rolled out to its launch pad at the Baikonur Cosmodrome in Kazakhstan today to begin counting down to a Thanksgiving Day liftoff of three new crew members to the International Space Station. NASA astronaut Chris Williams and Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev are scheduled to lift off aboard the Soyuz MS-28 spacecraft at 4:27 a.m. EDT (3:27 p.m. Baikonur time) on Thursday, Nov. 27. They will orbit Earth twice before docking to the Rassvet module at 7:38 a.m. the same day beginning an eight-month space research mission.

The Cygnus XL spacecraft, supporting the Northrop Grumman-23 commercial resupply services mission for NASA, was uninstalled today from the International Space Station. It will remain attached to the station’s Canadarm2 robotic arm until Monday, Dec. 1, clearing the way for the arrival of the crewed Roscosmos Soyuz MS-28 spacecraft on Thursday.

NASA, Northrop Grumman, and Roscosmos coordinated the spacecraft’s movement to prevent any unnecessary structural loads from being imparted on Cygnus XL and its solar arrays when the Soyuz MS-28 spacecraft docks to the Rassvet module, which is the adjacent docking port. The on-duty robotics officer in the Mission Control Center at NASA’s Johnson Space Center in Houston completed the maneuver, while agency astronauts Jonny Kim and Zena Cardman monitored from inside the space station.

Cygnus XL will be reattached to the space station on Dec. 1 and remain there until no earlier than March 2026, when it is scheduled to depart and dispose of several thousand pounds of trash during its destructive re-entry into Earth’s atmosphere

Qubesat-2    Updated: 19 Sep 2025         Responsible Operator    Rishabh Dave KI5YPK

Supporting Organisation    University of California Berkeley - Space Technologies at Cal (STAC)         
Contact Person    [email protected] 

Headline Details: The 2U Cubesat mission involves an amateur component and a science / education component: Amateur mission: the digipeater functionality will allow Amateurs to transmit packets of their own data to the satellite, which will be stored and re-transmitted by the satellite at a time of their choosing. This store and forward capability will allow amateurs to transmit packets from their location to any location in the world. Also, we will utilize the TinyGS open-source ground station network, ensuring widespread accessibility for amateur operators worldwide. Science / Education mission: Operate a proof-of-concept quantum gyroscope experiment developed by students at UC Berkeley. This will test use of Nitrogen-Vacancy (NV-) center diamonds in the conditions of low-earth orbit. A gyroscope like this may provide better accuracy and less noise than a MEMS gyroscope, while being more resistant to temperature and radiation degradation. Also, the size of the gyroscope is limited only by the size of a laser and RF signal generator, and so can be made smaller than other gyros based on other technologies. Proposing a UHF LoRa downlink with a 1025 baud data rate. Planning a Voyager Space launch from Wallops in April 2026 to the ISS.

Space Station First: All Docking Ports Fully Occupied, 8 Spacecraft on Orbit



Dec. 1, 2025: International Space Station Configuration. Seven spaceships are parked at the space station including the SpaceX Dragon cargo craft, the SpaceX Crew-11 Dragon spacecraft, JAXA’s HTV-X1 cargo craft, Northrop Grumman’s Cygnus cargo craft, the Soyuz MS-27 crew ship, and the Progress 92 and 93 resupply ships.
NASA
For the first time in International Space Station history, all eight docking ports aboard the orbital outpost are occupied following the reinstallation of Northrop Grumman’s Cygnus XL cargo spacecraft to the Earth-facing port of the station’s Unity module. The eight spacecraft attached to the complex are: two SpaceX Dragons, Cygnus XL, JAXA’s (Japan Aerospace Exploration Agency) HTV-X1, two Roscosmos Soyuz crew spacecraft, and two Progress cargo ships.
This milestone follows the reattachment of the Cygnus XL spacecraft, supporting the Northrop Grumman-23 commercial resupply services mission for NASA, which was removed last week by the robotics officer at the agency’s Mission Control Center in Houston using the space station’s Canadarm2 robotic arm. The Cygnus XL movement was coordinated between NASA, Northrop Grumman, and Roscosmos to provide appropriate clearance for the arriving crewed Soyuz MS-28 spacecraft on Nov. 27. 
Cygnus will remain attached to the orbiting laboratory until no earlier than March 2026, when it is scheduled to safely depart and dispose of up to 11,000 pounds of trash and unneeded cargo when it harmlessly burns up in Earth’s atmosphere.
Meanwhile, the 10-person Expedition 73 crew filled its day with biology and physics research while preparing to split up early next week.
Three new residents are living aboard the space station following the arrival of the Soyuz MS-28 spacecraft on Thursday, Nov. 27, 2025. NASA astronaut Chris Williams and Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev will stay in space until July 2026, conducting advanced space research benefiting humans living on and off Earth. Kud-Sverchkov and Mikaev have already begun studying how living in space affects the microcirculatory system in their hands, fingers, feet, and toes. Williams has been assisting his NASA crewmates with cargo activities.
On Dec. 8, the orbital outpost will return to seven members and become the Expedition 74 crew when NASA astronaut Jonny Kim and Roscosmos cosmonauts Sergey Ryzhikov and Alexey Zubritsky enter the Soyuz MS-27 spacecraft, undock from the Prichal module, and parachute to a landing in Kazakhstan. The trio performed pressure and leak checks on the Sokol launch and entry suits they will wear next week for the ride back to Earth. Ryzhikov continued packing cargo inside the Earth-bound Soyuz, while Zubritsky began handing over his responsibilities to his new Roscosmos crewmates. Kim, Ryzhikov, and Zubritsky are nearing the end of an eight-month space science mission that began on April 8, 2025.
Kim also joined his new crewmate Williams and NASA Flight Engineer Zena Cardman to open the Cygnus XL hatch following its reattachment Monday morning. The crew will continue unpacking some of the several tons of new science and supplies Cygnus XL delivered on Sept. 18.
Flight Engineers Mike Fincke and Kimiya Yui spent their day focusing on space research to learn about phenomena that can only be studied in the weightless environment of microgravity. Fincke, from NASA, first swapped computer hardware supporting a physics experiment that is studying ways to preserve cryogenic fluids in spacecraft fuel tanks. Next, he configured the new NanoRacks Thailand Liquid Crystals experiment, which will observe changes in the formation of flat liquid crystal films in microgravity. Yui, from JAXA, studied how the brain regulates its blood flow. He measured both his cerebral artery blood flow and blood pressure to help doctors understand potential space-related issues.
Flight Engineer Oleg Platonov spent Monday collecting, processing, and photographing microbe samples gathered throughout the station’s Roscosmos segment for analysis. He also transferred data highlighting the vibrations the station experiences while orbiting Earth to a laptop computer.
