All Space countdowns
US EVA-100
NASA astronaut Anil Menon and CSA astronaut Joshua Kutryk will exit the station’s Quest airlock to install and deploy an International Space Station Roll-Out Solar Array (IROSA) on the 2A electrical power channel. The solar array will be the seventh IROSA and will provide additional power to support critical station operations, including its safe and controlled deorbit. Location: International Space Station.
GSLV Mk II | IRNSS-1L (NVS-03)
Launch by Indian Space Research Organization. This is a replacement satellite for the Indian Regional Navigation Satellite System. The constellation will provide India with an alternative to GPS and will be used for military and civilian use. Located at a geosynchronous orbit, the system will be operated by the Indian government. From Satish Dhawan Space Centre, India.
RS-25 Engine Test
NASA is conducting a hot fire of an RS-25 engine as part of certification testing for future SLS (Space Launch System) rockets. The test of developmental RS-25 engine No. 10001 is planned to run for almost eight-and-a-half minutes (500 seconds) and throttle up to 111% of its rated power level. Location: Fred Haise Test Stand, NASA’s Stennis Space Center.
Falcon 9 Block 5 | Starlink Group 15-18
Launch by SpaceX. A batch of 27 satellites for the Starlink mega-constellation - SpaceX's project for space-based Internet communication system. From Vandenberg SFB, CA, USA.
Kinetica 2 | SpaceSail Polar Group TBD?
Launch by CAS Space. Low Earth Orbit communication satellites with Ku, Q and V band payloads for the G60 constellation operated by Shanghai Spacesail Technologies with funding backed by the Shanghai local government. Initial constellation will consist of 1296 satellites by 2027 with long term plans to expand it to 12000 satellites. From Jiuquan Satellite Launch Center, People's Republic of China.
Falcon 9 Block 5 | USSF-432
Launch by SpaceX. A classified mission for the United States Space Force. It is possibly a batch of classified LEO satellites based on SpaceX’s Starshield satellite bus, based on locations of rocket stage drop zones being exact fits with previous Starlink Group 15 launches. From Vandenberg SFB, CA, USA.
US EVA-101
NASA astronaut Anil Menon and CSA astronaut Joshua Kutryk will install and deploy the eighth and final IROSA on the 3B channel of the space station, completing the power augmentation upgrades. The final two roll-out solar arrays will complete the space station’s power system augmentation. Together, the eight roll-out arrays will increase available power by up to 30%, boosting the station’s electric power generation capacity from 160 kilowatts to approximately 215 kilowatts. Location: Internat
Falcon 9 Block 5 | Starlink Group 15-21
Launch by SpaceX. A batch of 27 satellites for the Starlink mega-constellation - SpaceX's project for space-based Internet communication system. From Vandenberg SFB, CA, USA.
BepiColombo Mercury Orbit Insertion
Orbital insertion around Mercury of the ESA-JAXA BepiColombo mission. Location: Mercury.
Solar Orbiter Venus 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. Location: Venus.
Europa Clipper Earth Flyby
NASA’s Europa Clipper will fly by Earth for a second and final gravity assist on its way to Jupiter. Location: Earth.
Boeing Starliner-1 Docking
The Starliner-1 spacecraft will dock autonomously to the International Space Station, carrying four astronauts to the International Space Station. Location: International Space Station.
Boeing Starliner-1 Landing
Following its deorbit burn, the Boeing CST-100 Starliner will reenter the Earth's atmosphere and land at the White Sands Missile Range using its parachutes. Location: White Sands Missile Range.
Boeing Starliner-1 Undocking
The Boeing CST-100 Starliner will undock from the International Space Station and conduct a deorbit burn as part of its first operational mission. Following the deorbit burn the capsule will renter the Earth's atmosphere and land at the 'White Sands Missile Range' using its parachutes. Location: International Space Station.
SNC-1 Dream Chaser Berthing
NASA TV will livestream the rendezvous and capture of Sierra Nevada Corporation's Dream Chaser cargo craft to the International Space Station. Location: International Space Station.
SNC-1 Dream Chaser Release & Reentry
The Sierra Nevada Corporation SNC-1 Dream Chaser will be unberthed from the ISS before re-entering the Earth's atmosphere and landing at Kennedy Space Center. Location: International Space Station.
SNC-1 Dream Chaser Landing
The Sierra Nevada Corporation SNC-1 Dream Chaser will land autonomously at the Launch and Landing Facility of Kennedy Space Center. Location: Kennedy Space Center, FL, USA.
Lucy Trojan Asteroid (3548) Eurybates & Queta Flyby
Flyby of the Trojan asteroid (3548) Eurybates and its satellite Queta by NASA's Lucy mission. Location: (3548) Eurybates.
