December
December TBD:
- A SpaceX Falcon Heavy rocket will launch the USSF 52 mission with the X-37b spaceplane for the U.S. Space Force.
- Firefly's Alpha FLTA004 Fly the Lightning mission will launch a payload for Lockheed Martin in low Earth orbit (LEO).
Dec. 1: Russia will launch a Soyuz rocket carrying the Progress MS-25 spacecraft to the International Space Station on a cargo and resupply mission.
Dec. 10: A SpaceX Falcon Heavy rocket will launch the U.S. Space Force's secretive X-37B space plane on its 7th mission to space. Falcon Heavy will launch from Launch Complex-39A, at NASA's Kennedy Space Center, in Florida. This marks the first time that the X-37B will launch on a Falcon Heavy. Delayed from Dec. 7.
Dec. 14: The Geminid meteor shower peaks tonight! The shower is active between Dec. 4 and Dec. 17.
Dec. 21: Today is the winter solstice for the Northern Hemisphere and the summer solstice for the Southern Hemisphere.
Dec. 21: The Ursid meteor shower peaks tonight! The shower is active from Dec. 13 to Dec. 24.
Dec. 24: A United Launch Alliance Vulcan Centaur rocket will launch on its inaugural flight with the Peregrine commercial lunar lander for Astrobotic. It will lift off from Space Launch Complex 41 at Cape Canaveral Space Force Station in Florida.
Dec. 26: The full moon of December, known as the Cold Moon, will occur at 7:33 p.m. EST (0033 GMT on Dec. 27).
2024
Jan. 3-4: The time of the shower's peak is set for about 4 a.m. EST on Jan. 4, which favors eastern North America, as previously reported on Space.com. Viewing conditions for the Quadrantids is good for 2024 as there will be a 47% illuminated waning crescent moon in the constellation Virgo during the peak, providing much less of a hindrance to meteor viewing compared to 2023.
Jan. 10: Axiom Space's third private astronaut mission will launch to the ISS from NASA's Kennedy Space Center in Florida, using SpaceX's Crew Dragon spacecraft and Falcon 9 rocket. The four crewmembers include a former NASA astronaut, a European Space Agency reserve astronaut and a passenger who flew to suborbital space with Virgin Galactic earlier this year.
Jan. 12: A SpaceX Falcon 9 rocket will launch the IM-1 mission with the Nova-C lander built and owned by Intuitive Machines from the Kennedy Space Center in Florida.
Jan. 25: January's full moon, known as the Wolf Moon, or Micro Moon, will rise.
Feb. 9: The moon will be at its closest point to Earth in orbit — but unfortunately, this "supermoon" will be too close to the sun to be visible to skywatchers on the ground. Despite its proximity to Earth, skywatchers won't be able to see the moon, because it will be a new moon. It will be too near to the sun to be seen, and will be invisible as it passes across our daytime sky.
March: A United Launch Alliance Atlas 5 rocket will launch the USSF 51 mission for the U.S. Space Force.
April: A United Launch Alliance Atlas V rocket will launch Boeing's CST-100 Starliner spacecraft on its first crewed flight. NASA astronauts Butch Wilmore and Mike Fincke, along with an unidentified third crew member, will fly on the mission. The Crew Test Flight to the International Space Station will lift off from Cape Canaveral Space Force Station, Florida.
