Falcon 9 Block 5 | USSF-627
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.
Note: Launch vehicle name is provisional.
First orbital full version launch of the South Korean military small satellite launch vehicle, after 2 sub-orbital tests of individual stages on 30 March and 30 December 2022, and 1 orbital test flight without the 2nd stage on 4 December 2023. Details TBD.
Amazon Leo, formerly known as Project Kuiper, is a mega constellation of satellites in Low Earth Orbit that will offer broadband internet access, this constellation will be managed by Kuiper Systems LLC, a subsidiary of Amazon. This constellation is planned to be composed of 3,276 satellites. The satellites are projected to be placed in 98 orbital planes in three orbital layers, one at 590 km, 610 km and 630 km altitude.
45 satellites will be carried on each Vulcan launch.
Starship | Starlink Group 31-2 (Starship Flight 15)
SpaceX
15th test flight of the two-stage Starship launch vehicle and 4th flight of Starship V3. Second Starship flight to deploy satellites (a group of Starlink satellites known as Starlink Group 31-2) into stable Low Earth Orbit and first ever to attempt returning the Starship 2nd stage back to the launch site.
The ship is expected to fly at an altitude approximately 275 km above Earth and complete approximately 14 orbits around the planet for more than 22 hours, with the ship expected to attempt returning back to Starbase, Texas on its launch pad by pad arms catching.
The booster’s primary test objective on Flight 15 will be executing a successful launch, ascent, stage separation, boostback burn, and landing by pad arms catching. This will also be the 1st Starship V3 booster to attempt returning to its launch site.
Starship will deliver 26 Starlink V3 satellites to orbit for the second time, which aim to greatly expand the network's capacity and user speeds. Each Starlink V3 satellite will add 1 Tbps of capacity to the constellation. 3 of the satellites have been modified with a suite of cameras to scan Starship’s heatshield and transmit imagery down to operators.

China Aerospace Science and Technology Corporation
A batch of 9 Low Earth Orbit communication satellites for the Chinese state owned SatNet constellation operated by the China Satellite Network Group.
The constellation will eventually consists of 13000 satellites.
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.
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.
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.
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.
