Amazon shipped another batch of internet-beaming satellites into orbit on Monday atop a SpaceX Falcon 9 rocket, after four previous launch attempts were interrupted by weather issues.

Monday’s launch is the fourth Kuiper mission, and Amazon now has 102 satellites in orbit.

The Falcon 9 rocket lifted off from Cape Canaveral, Florida, at 8:35 a.m. ET. Roughly an hour after launch, SpaceX confirmed all 24 of Amazon’s Kuiper satellites were successfully deployed.

The mission was originally scheduled for last Thursday, but SpaceX was forced to scrub the launch, along with three more attempts over the past few days due to rainfall.

For the second time, Amazon turned to Elon Musk’s SpaceX, its chief competitor in the low-earth orbit satellite market, for help building out its constellation.

SpaceX’s Starlink is currently the dominant provider of low-earth orbit satellite internet, with a constellation of roughly 8,000 satellites and about 5 million customers worldwide.

Amazon is racing to get more of its Kuiper satellites into space to meet a deadline set by the Federal Communications Commission.

The FCC requires that Amazon have about 1,600 satellites in orbit by the end of July 2026, with the full 3,236-satellite constellation launched by July 2029.

Amazon has booked up to 83 launches, including three rides with SpaceX.

While the company is still in the early stages of building out its constellation, Amazon has already inked deals with governments as it hopes to begin commercial service later this year.
