US EVA-94
EVA
NASA astronauts Jessica Meir and Chris Williams will exit the station’s Quest airlock to prepare the 2A power channel for future installation of International Space Station Roll-Out Solar Arrays. Once installed, the array will provide additional power for the orbital laboratory, including critical support of its safe and controlled deorbit.
Artemis II SLS Rollout #2
Rollout
NASA will roll out their second fully stacked Space Launch System (SLS) rocket back to LC-39B after a rollback from the pad to investigate issues with the upper stage helium tanks. The rollout is expected to take up to 12 hours.
Progress MS-33 Docking
Docking
The Progress MS-33 spacecraft is scheduled to autonomously dock to the Poisk module of the ISS.
RV-X Flight test
Vehicle Testing
Using a small experimental aircraft (RV-X) with a diameter of approximately 1.8 m and a height of approximately 7.3 m, flight tests will be conducted at an altitude of approximately 10 m and covering a horizontal distance of approximately 15 m.
US EVA-95
EVA
Two astronauts will replace a high-definition camera on camera port 3, install a new navigational aid for visiting spacecraft, called a planar reflector, on the Harmony module’s forward port, and relocate an early ammonia servicer jumper — a flexible hose assembly that connects parts of a fluid system — along with other jumpers on the station’s S6 and S4 truss.
Hayabusa2 S-Type Asteroid (98943) Torifune Flyby
Flyby
As part of its mission extension, JAXA's Hayabusa2 spacecraft will observe S-type asteroid (98943) Torifune during a high-speed fly-by.
Juice Earth Flyby
Flyby
Third flyby of ESA's Jupiter Icy Moons Explorer (Juice) mission on its way to the Jovian system.
BepiColombo Mercury Orbit Insertion
Orbital Insertion
Orbital insertion around Mercury of the ESA-JAXA BepiColombo mission.
Solar Orbiter Venus Flyby
Flyby
Solar Orbiter, a partnership between ESA and NASA, will perform a gravity assist maneuver with Venus on December 24, 2026. Throughout its mission it also makes repeated gravity assist flybys of Venus to get closer to the Sun, and to change its orbital inclination, boosting it out of the ecliptic plane, to get the best – and first – views of the Sun’s poles.
Europa Clipper Earth Flyby
Flyby
NASA’s Europa Clipper will fly by Earth for a second and final gravity assist on its way to Jupiter.
