Mission Overview This was SpaceX’s 12th dedicated rideshare mission to SSO. Its payloads ranged in size from picosatellites of less than a kilogram that are only a few centimeters on a side, to a satellite massing three-quarters of a tonne. Rideshare integrators handling payloads on this flight include Exolaunch, ISILaunch, SEOPS, Maverick Space, D-Orbit, and Impulse Space. While most of the payloads will be released directly from the launch vehicle, there are Orbital Transfer Vehicles (OTVs) from D-Orbit and Impulse Space which will later release more spacecraft. SEOPS recently announced the purchase of a Falcon 9 launch in 2026 for a dedicated rideshare to GTO. Maverick and ISISpace will collaborate on booking customers for the flight. Below is a summary of the payloads that we are aware of on the flight. Sizes for CubeSats are given in terms of 10 cm cubes, with a 6U CubeSat being approximately 30 x 20 x 10 cm. Sizes for PocketQubes are given in terms of 5 cm cubes, with a 1.5P PocketQube being approximately 7.5 x 5 x 5 cm. MBZ-Sat Credit: MBRSC Atop the payload stack was MBZ-SAT, a high-resolution optical Earth observation satellite developed by the Mohammed Bin Rashid Space Centre (MBRSC) in the United Arab Emirates. It has a mass of 750 kg and deployed dimensions of 3 x 5 m. UAE also provided some smaller educational satellites for this launch. HCT-Sat 1 from Higher Colleges of Technology in association with MBRSC is a 1U spacecraft that includes an imaging payload. The National Space Science and Technology Center at UAE University had AlAinSat-1, a 3U spacecraft with remote sensing payloads developed in association with Spain’s Polytechnic University of Catalonia, Japan’s Kyushu Institute of Technology, and Indonesia’s Telkom University. Italy’s D-Orbit had a pair of its ION OTVs, named Amazing Antonius and Eminent Emmanuel. These will carry multiple hosted payloads and customer satellites for later deployment, including seven PocketQubes manifested by Alba Orbital. Impulse Space had its LEO Express 2 mission, the second flight of its Mira orbital transfer vehicle with a mass of 294 kg at launch. Mira will host several space situational awareness camera systems from Starfish Space, HEO Robotics, and Impulse. This vehicle has an upgraded communications system to enable longer mission duration. While Impulse’s first Mira vehicle was declared to be past the active phase of its mission in mid-2024 due to degraded communications, orbital tracking data shows it performed a series of maneuvers starting in mid-December and continuing into January. Riding on board the Impulse OTV were two satellites that will be deployed about a week after launch. South Korea’s TelePIX has BlueBon, a 6U-XL CubeSat with medium-resolution imaging and AI processing onboard to monitor “Blue Carbon”, based on detecting algae in marine ecosystems. Spanish firm FOSSA Systems has FOSSASat TAT-0, a 3U CubeSat that is a new form factor for the company after earlier launches of PocketQubes and flat satellites. FOSSA also had two more spacecraft on the flight, FOSSASat TAT-A & TAT-E. One or more of these will host an encrypted IoT payload for WISeKey. SAT GUS from Mark Rober and CrunchLabs is a microsatellite built by Tyvak that will allow users to upload photos for display on a phone integrated into the satellite. When the satellite passes over the user’s location it will take an image of the user’s picture on the phone display with their location on Earth in the background. The spacecraft for Varda’s second mission. Credit: Rocket Lab Varda’s Winnebago-2 is its second Rocket Lab-built satellite with a reentry capsule. Varda is working on manufacturing pharmaceuticals in microgravity conditions, with its first flight demonstrating production of the drug ritonavir. After Varda’s first mission faced a lengthy wait on orbit for landing permission from the FAA and the Utah Test and Training Range, this second mission has the necessary paperwork in hand to land at a new site, Australia’s Koonibba Test Range. The capsule also carries a payload for the Air Force Research Lab to collect reentry data during its descent. Another company, Inversion Space, also had a reentry capsule demonstration on this flight. The 63 kg Ray 1 spacecraft will put its capsule on a reentry trajectory for a landing off the coast of California. Centauri 7 & 8 are a pair of 12U satellites from Australia’s Fleet Space with IoT and narrowband communications functionality.

AAC Clyde Space had Sedna-2, a 4U satellite with an AIS payload for maritime monitoring. Portugal’s LusoSpace had PoSat-2, a 3U CubeSat with AIS payload for maritime monitoring. Orbital parameters for the ANSER Follower-1 satellite over the last year. Variations in the rate of descent over the last several months have brought it to slightly above the expected deployment altitude of its new Leader launching on Transporter 12. Credit: CelesTrak The ANSER mission from Spain’s INTA and ESA to monitor water quality and climate change, consisting of a trio of formation-flying 3U CubeSats with a Leader and two Followers, launched on a Vega rocket in October 2023 with the Leader failing to deploy. The two Follower satellites have since been drifting down from 570 km towards their science orbit at 500 km, using differential drag to control their rate of descent. They will try to rendezvous with a new Leader-S satellite launching on Transporter 12. Digantara and OrbAstro had SCOT, a 6U CubeSat hosting Digantara’s Space Climate and Object Tracker sensor to monitor space debris and space weather.

Payload information for the flight will be updated as more information becomes available. Some companies do not provide information before the launch. Notes on previous SpaceX rideshare missions. Bandwagon-2: Launched December 21, tracking data for these payloads is just starting to become available. Twenty-nine objects are associated with the launch, with orbit data given for 28 of those. The orbit of South Korea’s KORSAT-2 military reconnaissance satellite is not publicly shown. Aside from KORSAT-2, the objects have not been named yet on Space-Track or Celestrak. SpaceX said 30 payloads would be on the flight. (Lead Image: Falcon 9 launches Transporter 12 from SLC-4E. Credit: SpaceX)
