For the second time in a row, SpaceX plans to launch a rocket from California on a classified mission for the U.S. Space Force.
But Arizona residents may not have as easy of a time spotting the Falcon 9 rocket soaring overhead this time around after it gets off the ground from the Vandenberg Space Force Base.
That's because SpaceX's workhorse rocket is due to fly at a southern trajectory that won't be as easily visible to the state. Fortunately, SpaceX will still have you covered with a livestream of the mission if you're really interested.
Keep in mind that postponements due to weather or issues with rockets are common with spaceflight. If you're going to try to spot the rocket launch, check back with azcentral.com for any updates on the mission.
In the meantime, here's what to know about the launch from neighboring California, as well as when and where to potentially see the rocket in Arizona.
Is there a rocket launch today? Next mission from California
SpaceX is working toward a Tuesday, Sept. 15, launch from Southern California, with a four-hour launch window opening at 6 p.m. PT, according to a launch alert.
A Federal Aviation Administration operations plan advisory suggests a backup opportunity is available the next day if the launch were to be postponed.
Will liftoff from Vandenberg be visible in Arizona? What to know about trajectory
The launch will take place from Space Launch Complex 4-East (SLC-4E,) which SpaceX leases as a launch site for its Falcon 9 rocket at the Vandenberg Space Force Base in Santa Barbara County.
Because the rocket is due to fly at a southern trajectory, it may not be easily visible from Arizona.
What's the mission? SpaceX to conduct Space Force launch
The next launch from Vandenberg is another classified mission for the U.S. Space Force, this one known as USSF-259. Multiple spaceflight outlets have reported that the mission could be the delivery of a batch of military satellites that will operate in low-Earth orbit – a region closer to Earth's atmosphere.
SpaceX's famous two-stage 230-foot Falcon 9 rocket, one of the world's most active, will be used to deliver the payload.
Weather favorability: Here's the forecast during the launch window
Patchy fog and cloudy conditions are forecasted during the Sept. 15 launch window for Santa Barbara County, where the Vandenberg Space Force Base is located, according to the National Weather Service.
The below graphic from the NWS, which shows the potential for clouds in Arizona during the targeted window, should help spectators know if conditions will be ideal near them. Blue shading indicates clear skies, while areas with gray shading and higher percentage numbers indicates a higher chance for clouds.
How to watch SpaceX launch livestream
Fortunately for those in Arizona interested in watching the launch, SpaceX also provides a live webcast of its missions.
The launch will be available to stream on the company's website beginning about 10 minutes before liftoff. SpaceX may also provide updates on social media site X.

Where to watch SpaceX Falcon 9 in Arizona
Because of Arizona's proximity to the launch site, there's a good chance people there can see the spacecraft streak across the sky, especially at night or very early morning.
