If you can't see SpaceX's Starship in person, you can score a model of your own. Standing at 13.77 inches (35 cm), this is a 1:375 ratio of SpaceX's Starship as a desktop model. The materials here are alloy steel and it weighs just 225g.

SpaceX is being extra careful with this launch to test the reuse of its massive Super Heavy booster. The booster on Flight 9 was use to launch the Flight 7 Ship in January, with only four of its 33 Raptor engines being replaced for this mission.
The entire Starship vehicle, when assembled, stands about 400 feet (122 meters), making it the world's largest and most powerful rocket. It is designed to be fully reusable to enable trips to low Earth orbit, the moon (NASA's picked Starship to land Artemis astronauts in 2027), and ultimately fly to Mars.

SpaceX CEO Elon Musk will also host a live presentation on the company's Mars exploration plan using Starship entitled "The Road to Making Life Multiplanetary." That talk was originally scheduled to begin hours ahead of the Flight 9 launch at 12:55 p.m. EDT (1655 GMT). But Musk announced it was postponed until after the launch, and is now set to begin no earlier than 9 p.m. EDT (0100 GMT). You can watch it in this window.

If you plan to travel to South Texas to see Starship Flight 9 in person, there are several places where you can observe the launch.
South Padre Island offers a clear view of the launch from its Cameron County Amphithear in Isla Blanca Park. The nearby shoreline of Port Isabel is another option, but plan ahead as traffic can be heavy at times.
How long is SpaceX's Starship Flight 9?

SpaceX's Starship Flight 9 mission is expected to last just over one hour and is hoping to replicate the path of its immediate predecessor, Starship Flight 8 in March, before that mission ended in failure. SpaceX had hoped to attempt a mock Starlink satellite deployment on Flight 7 (among other tests) before attempting a "soft landing" in the Indian Ocean and sinking.
The Starship upper stage will again target multiple in-space objectives, including the deployment of eight Starlink simulators, similar in size to next-generation Starlink satellites," SpaceX wrote in a mission overview. "The Starlink simulators will be on the same suborbital trajectory as Starship and are expected to demise upon entry. A relight of a single Raptor engine while in space is also planned."
The Super Heavy booster, meanwhile, will NOT attempt to return to its launch site and be captured by SpaceX's giant Mechazilla chopsticks. Instead, it will attempt a soft landing in the Gulf of Mexico and be discarded. That's because it is the first time SpaceX is attempting to refly such a huge rocket.
