SpaceX set to launch Falcon 9 rocket on Wednesday. Here's how to see it in Arizona

This year, Arizonans have been able to witness history from their own backyards. If you have missed out on the last few monumental launches, here is your opportunity to join fellow Arizona residents in watching these rockets pass over the state.

SpaceX expects to launch a Falcon 9 rocket containing 20 Starlink satellites from Vandenburg Air Force Base on Wednesday, July 10.

Liftoff was targeted for 7 p.m. If needed, there will be backup opportunities for liftoff until 11 p.m. on Wednesday and starting again at 3:37 p.m. on Thursday, June 11.

Here's everything you need to know about the SpaceX launch and how to watch it from home.

Where in California does SpaceX launch from?

The rocket is scheduled to launch from Vandenberg Space Force Base on the central coast of California.

The base is located in Santa Barbara County, about 5 miles from the small town of Vandenberg Village. The closest city is Lompoc, located about 10 miles south of the base, followed by Santa Maria, about 17 miles north.

What is SpaceX?

Space Exploration Technologies Corporation, more widely known as SpaceX, is an astronautics company owned and co-founded by multibillionaire Elon Musk.

The company manufactures spacecraft and launches communication satellites aimed at delivering broadband internet service into space.

What is Falcon 9?

According to the SpaceX website, Falcon 9 is the first orbital-class reusable rocket. The two-stage rocket transports people and payloads — the portion of the spacecraft that produces mission data and then relays it back to Earth —into space and back.

This mission utilizes a reusable first-stage booster, the engines responsible for liftoff that detach from the rest of the rocket once the spacecraft leaves Earth's atmosphere. Falcon 9's first stage booster will reorient itself after separation and land on a drone ship stationed in the Pacific Ocean where it can be used.

This engine has been a crucial component in 18 other SpaceX missions and exemplifies the company's mission of improving the future of space travel. Falcon 9's reusability allows SpaceX to "refly the most expensive parts of the rocket" which creates more affordable space access, according to the website.

What is Starlink?

Starlink is a satellite constellation that uses a low Earth orbit to function. According to the SpaceX website, Starlink is the first and largest satellite constellation to travel in a low Earth orbit to deliver broadband internet across the globe.

While most satellite internet services operate from single geostationary satellites orbiting Earth at about 22,236 miles, Starlink is a constellation of thousands of satellites that orbit the planet at about 341 miles.

The low-orbit nature of Starlink's satellites lowers latency and data time between the user and the satellite, which improves the performance of high-data-rate activities like streaming, online gaming and video calls.

Starlink also aims to eliminate cell service dead zones through its Direct to Cell program. Like a cell tower in space, Direct to Cell will allow access to texting, calling, and browsing in traditionally remote areas.

How to watch the launch

The launch in California will create a light display over many parts of Arizona, so you can actually see the spacecraft from the comfort of your own backyard.

If you want to watch the launch online, a live webcast will stream on SpaceX's X, formerly known as Twitter account about five minutes before liftoff.
