ISS: Expedition 75

Expedition 75 began with undocking of Soyuz MS-28 on July 26, 2026.

On August 06, 2026 Jessica Meir and Anil Menon performed the first spacewalk in Expedition 75 (6h 27m). They exited the Quest airlock to install hardware that will modify the station's 3B power channel and prepare it for the future installation of an International Space Station Roll-Out Solar Array (IROSA). The solar array, scheduled for delivery later this year, will be the seventh IROSA and will provide additional power to support critical station operations, including its safe and controlled deorbit.
Toward the end of the spacewalk, a carbon dioxide sensor on Menon's spacesuit indicated an unexpected data reading. Anil Menon reported no other issues during the spacewalk.
Although the sensor returned to normal readings following removal of the suit, engineers on the ground will continue to evaluate over the coming days whether to change suits for the next spacewalk. As a result, NASA moved the next spacewalk to replace a Space-to-Ground antenna on the space station to August 18, 2026.

On August 18, 2026 Anil Menon and Sophie Adenot performed the second spacewalk and tried to replace but failed to a Space-to-Ground antenna on the orbital complex (6h 23m). The antenna is a critical communication system NASA uses to transmit data and high speed communication between the Mission Control Center in Houston and the space station.

In the next spacewalk on August 25, 2026 Anil Menon and Sophie Adenot finished replacing the Space-to-Ground antenna on the International Space Station (6h 30m). The pair began the work on August 18, 2026.
Menon ride the Canadarm2 robotic arm to retrieve a spare antenna that Adenot released from an external platform. Together, they installed the antenna on the Z1 truss segment above the station's Unity module. The astronauts then made the precise electrical and data connections needed to activate the spare antenna for high-speed transmissions with mission control.

On September 01, 2026 the next spacewalk occurred (6h 49m). Sophie Adenot and Jessica Meir replaced a retroreflector on the forward port of the space station's Harmony module to support spacecraft navigation during rendezvous and docking operations. After installing the reflector, the crew worked to install jumper cables for the data-relay systems, prepared the Alpha Magnetic Spectrometer's radiator for future maintenance, and replaced a high-definition camera on the station's truss.

Before Progress MS-35 arrives, the Progress MS-33 spacecraft undocked from the space station at approximately 15:18 UTC on September 07, 2026 for its departure and planned destructive re-entry.

The unpiloted Progress MS-35 resupply spacecraft launched at 13:33:54.560 UTC on September 16, 2026 on a Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan.
Progress MS-35 will deliver over 2,400 kg of cargo to the International Space Station:
· 842 kg of fuel for station refueling;
· 420 kg of water for the crew;
· 50 kg of oxygen to replenish the ISS atmosphere;
· 275 kg of food, including fresh produce;
· 357 kg of sanitation and hygiene equipment and supplies;
· 20 kg of medical supplies and countermeasures against the effects of weightlessness;
· 525 kg of equipment and consumables for station maintenance and crew scientific activities.
After a three-day trip to the space station, Progress docked autonomously to the Poisk module's space-facing port at 13:44:20 UTC on September 19, 2026.
The spacecraft will remain docked to the orbiting laboratory for about five months before departing to re-enter Earth's atmosphere, where it will harmlessly burn up over the Pacific Ocean.

On October o4, 2026 the International Soace Station changed from Jessica Meir to Pyotr Dubrov.

SpaceX Crew-12 undocked from the International Soace Station on October 07, 2026 at about 12:05 UTC.

After delivering more than 11,000 pounds (4,535 kilograms) of supplies, science experiments, and other cargo to the International Space Station for NASA, Northrop Grumman's Cygnus XL "S.S. Steven R. Nagel" spacecraft departed, October 09, 2026 at 16:43 UTC as part of the company's Commercial Resupply Services-24 mission, or Northrop Grumman CRS-24.
Flight controllers on the ground sent commands for the space station's Canadarm2 robotic arm to detach the Cygnus XL spacecraft from the Unity module's Earth-facing port and maneuver it into position for release at 16:45 UTC. NASA astronaut Luke Delaney monitored the operation from aboard the orbital complex.
Loaded with thousands of pounds of disposal items and other unneeded cargo, Cygnus XL will deorbit, October 11, 2026 for a destructive re-entry into Earth's atmosphere, where it will safely burn up.

The Dragon spacecraft SpX-25 or CRS-35 launched on October 13, 2026 at 10:33:44 UTC on a Falcon 9 rocket from the Cape Canaveral Space Force Station in Florida.
CRS-35 carried 2,867 kg of cargo to the Station, including
593 kg of science experiments,
383 kg of crew supplies,
362 kg of vehicle hardware,
189 kg of spacewalk equipment, and
36 kg of computer resources.
Each resupply mission to the station delivers scientific investigations in biology and biotechnology, Earth and space science, physical sciences, and technology development and demonstrations. Cargo resupply from U.S. companies ensures a national capability to deliver scientific research to the space station, significantly increasing NASA's ability to conduct new investigations aboard humanity's laboratory in space.
In addition, the Cargo Dragon carried 1,195 kg of cargo in its unpressurized trunk.
In addition to food, supplies, and equipment for the crew, Dragon will deliver the final sets of International Space Station Roll-Out Solar Arrays, called IROSA, which astronauts will install during future spacewalks to complete station's power augmentation. Once installed, the arrays will provide additional power to support critical station operations, including its safe and controlled deorbit.
The mission also transports several new experiments to the orbital complex, including hardware to manufacture artificial retinas in microgravity that could help restore vision for patients on Earth and 3D heart cell models to advance large-scale drug testing on future space missions. Dragon also carries materials to study how a new type of glass is formed in microgravity, and brain organoids that could uncover potential treatment targets for neurodegenerative diseases like Alzheimer's, Parkinson's, and multiple sclerosis.
At 14:27 UTC on October 15, 2026, the SpaceX Dragon spacecraft docked to the space-facing port of the International Space Station's Harmony module.
The spacecraft is scheduled to remain at the space station until mid-November 2026 when it will depart and return to Earth with time-critical research and cargo, splashing down off the coast of California.
