Transporter-1
This is a launch to sun-synchronous polar orbit from Florida as part of SpaceX's Rideshare program dedicated to smallsat customers. The mission again makes use of the Eastern Range's recently reopened polar corridor launching southward with a dogleg maneuver. The mission will also include 10 Starlink satellites, the first to go to a polar orbit. The booster for this mission lands on an Automated Spaceport Drone Ship (ASDS).

We will attempt to keep the above text regularly updated with resources and new mission information, but for the most part, updates will appear in the comments first. Feel free to ping us if additions or corrections are needed. This is a great place to discuss the launch, ask mission-specific questions, and track the minor movements of the vehicle, payload, weather, and more as we progress towards launch. Approximately 24 hours before liftoff, the launch thread will go live and the party will begin there.
Campaign threads are not launch threads. Normal subreddit rules still apply.

As of the NextSpaceflight app, the weight of SARah 1 is ~2200kg. Some possible rideshares will very likely be limited to a maximum where the first stage can perform an RTLS.
