As smoke from hundreds of burning wildfires spread across Canada and the United States, the first three operational satellites in the Google-backed FireSat program successfully launched into orbit. The satellites will begin providing wildfire detection capable of spotting even small fires in the United States, Australia, and Europe before the end of the year.

The launch of the microsatellites aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California on July 7, 2026 marks a transition to “initial operational capability” for the FireSat constellation managed by the nonprofit Earth Fire Alliance. After a three-month testing period, the three satellites will begin actively providing data to fire agencies while covering every fire-prone region on Earth at least twice per day.

FireSat represents the first satellite constellation purpose-built for detecting wildfires, including spotting smaller fires that other satellites may miss. The satellites were designed by California-based satellite manufacturer Muon Space and have received over $15 million from Google to support initial deployment. Other notable financial supporters include the Bezos Earth Fund that committed $26 million.

New navigation satellites in low-Earth orbit could provide 100 times stronger signal strength compared to GPS and other global navigation satellite systems operating from higher orbital altitudes—enabling greater location accuracy within dense cities, under thick foliage, and even inside buildings. Such signals would also likely prove more resilient to interference at a time when commercial flights, maritime shipping, and even various smartphone apps face increasingly widespread disruption from GPS jamming.

That vision may start to take shape when the first six production satellites of California-based Xona Space Systems are scheduled to launch in October 2026, with early service starting in 2027. Once the full constellation of 258 Pulsar satellites has been launched in the following years, Xona claims that customers will be able to accurately pinpoint their locations anywhere on Earth to within several centimeters.

“That added power means that we can get into that indoor environment that GPS can't get to today,” Adrien Perkins, co-founder and VP of engineering at Xona Space Systems, told Ars. “Our higher power allows you to get into those jamming environments a lot further than you would with GPS by itself.”

It wasn't easy to find anyone outside of SpaceX clamoring for a rocket like Starship just 10 years ago. Today, the space industry can't wait for Starship to finally deliver.

With a payload capacity of more than 100 metric tons (220,000 pounds) to low-Earth orbit, SpaceX's new rocket is changing the thinking of just about everyone in the space industry. With the unrealized but potentially game-changing benefits of refueling, Starship could carry the same amount of payload to higher orbits, the Moon, or Mars.

It's important to note that Starship is still very much in its experimental phase, far from proving Elon Musk's loftiest claims about what it can do. Still, NASA and the US military are considering novel ways to use Starship to fly to the Moon or transport cargo to far-flung war zones. Scientists are eager to use its enormous volume to launch giant space telescopes. Competitors are taking notice. China, the strongest strategic adversary America has ever faced, is looking for its own Starship. Now, some US satellite manufacturers are adapting for the substantial capacity of the world's most powerful rocket.
