SpaceX will begin another busy year with the launch of the Transporter-6 rideshare mission from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station (CCSFS). The mission is due to lift off at 9:56 AM EST (14:56 UTC) on Tuesday, Jan. 3, 2023. Falcon 9’s first stage will return to land at Landing Zone-1 at CCSFS approximately eight and a half minutes after launch.
The weather forecast from the 45th Weather Squadron shows a 90% chance of acceptable weather on Tuesday, dropping slightly to 80% on Wednesday at the same time of day should the launch be delayed.
This is the sixth dedicated rideshare mission organized by SpaceX and is carrying 114 payloads into orbit — some of which will be deployed later from a number of space tugs that are on the mission. The payloads range in size from picosatellites of less than a kilogram — measuring only a few centimeters on each side — to microsatellites massing around 100 kg.
The Transporter missions are intended to provide a consistent cadence of rideshare opportunities to popular orbits such as Sun-synchronous orbit (SSO). As with many other satellite missions in 2022, the Transporter-6 launch date slipped from its original October 2022 target, ending up at the beginning of 2023. There are three additional Transporter missions scheduled for 2023, launching in the first, second, and fourth quarters of the year.
The payloads will be deployed into an SSO of approximately 525 km in altitude and a 97.6-degree inclination. Payload deployments will begin around an hour after launch and last for about half an hour.
The Falcon 9 launch vehicle for this mission features booster B1060-15, which will tie the record for most flights of a Falcon 9 booster at 15. This record was just set in December 2022 as SpaceX continues to increase the longevity of its booster fleet. B1060 previously launched a GPS satellite, geostationary transfer orbit missions for Turksat and Intelsat, the Transporter-2 rideshare, and 10 Starlink missions.

While some Transporter customers deal directly with SpaceX to get a ride for their spacecraft, most of the payloads are handled by launch integrators who buy ports on the payload stack and then assemble multiple customers into that space. The payloads will then either deploy directly from the launch adapter or from a separable deployer or space tug that will release payloads at a later time — possibly after adjusting the orbit.
ISILaunch is handling the integration of CubeSat deployers on two of the ports, some of which are being done on behalf of launch service providers Spaceflight and SpaceBD. The company ExoLaunch has a variety of CubeSat and microsatellite customers deploying from multiple ports on the payload stack. Maverick Space will also be integrating some United States government payloads onboard. Geometric Energy Corporation had planned to launch several payloads on the Maverick port, but those have since been delayed to a later flight.
Italian firm D-Orbit is flying two of their ION tugs on this mission. ION SCV-007 (Glorious Gratia) and ION SCV-008 (Fierce Franciscus) will carry a variety of spacecraft and hosted payloads for customers including Astrocast and AAC Clyde Space.
Momentus is launching its second test flight of a space tug with Vigoride-5. After experiencing several problems with its previous flight, Momentus will test an upgraded design while deploying a spacecraft for Qosmosys and hosting a payload for the California Institute of Technology (Caltech). Caltech’s Space Solar Power Demonstration One (SSPD-1) payload will test several technologies related to solar power generation and deployment mechanisms.

Launcher Inc. has its first Orbiter space tug on board. Launcher is also working on its own launch vehicle, meaning that it will eventually be able to provide a complete end-to-end space transportation service. The Orbiter tug features a propulsion system using ethane and nitrous oxide as propellants. Orbiter SN1 carries a variety of customer spacecraft and hosted payloads. Spacecraft are to be deployed for customers Skyline Celestial, Innova Space, NPC Spacemind, Bronco Space, Standford Student Space Initiative, and others. Hosted payloads include a phased array antenna for CesiumAstro, cremated remains for Beyond Burials, and others.
EPIC Aerospace will also debut its Chimera space tug with the CHIMERA LEO 1 spacecraft. These tugs feature a propulsion system with non-toxic liquid propellants.
Many of the payloads on this launch are intended for Earth Observation (EO) missions, whether they use optical imaging, Synthetic Aperture Radar (SAR) imaging, or listen for radio frequency transmissions to perform signals intelligence duties.
The optical imaging satellites include Planet’s Flock 4Y Super Dove satellites. These 36 spacecraft will replenish the Dove constellation with newer models that provide 8-band multispectral imaging.
Satellogic is expanding its constellation to 30 spacecraft with four more high-resolution satellites onboard Transporter-6: Newsat 32 (Albania 1), Newsat 33 (Albania 2), Newsat 34, and Newsat 35. The government of Albania will have priority access to the Albania 1 & 2 satellites.
Open Cosmos is launching Menut, a 6U imaging satellite with a 5 m resolution that will prioritize taking imagery of the Catalonia region of Spain. Poland’s Scanway Space will have STAR VIBE, a 6U satellite testing an Earth observation telescope as well as a satellite self-inspection imager on a small boom.
The volume of CubeSats is usually given in units — “U” — of 10 x 10 x 10 centimeters. For example, a 6U CubeSat would measure 10 x 20 x 30 centimeters.
EOS Data Analytics — founded by Max Polyakov — has EOS Agrisat-1, the first satellite in their Earth imaging constellation focused on agricultural uses. The 100 kg-class satellite was built in South Africa by Dragonfly Aerospace and provides both panchromatic imaging at 1.4 m resolution and multispectral imaging at 2.8 m resolution.
For SAR imaging applications, Umbra Lab continues to expand its constellation with two more microsatellites, Umbra 04 and 05. ICEye has three more SAR satellites (X21, X22, and X27) onboard.
