SpaceX aims to launch the seventh Starship flight test on Jan. 10. It will mark the first time the company attempts to deploy a payload during the flight.

In a first, the next SpaceX Starship set to blast off from South Texas will attempt to release 10 dummy satellites during its journey around the world — but the timing of mission remains uncertain. CEO Elon Musk said via social media last week the launch could be as soon as Friday but neither the commercial space company nor federal regulators have confirmed the timing.
