Amazon's satellite internet chief sent a memo to staff addressing last week's dramatic Blue Origin rocket explosion, which threatens to disrupt the internet giant's most important space project.

The explosion occurred Thursday during a hot-fire test of Blue Origin's New Glenn rocket at Cape Canaveral. The rocket erupted into a massive fireball on the launch pad ahead of a planned mission that was expected to carry some of Amazon's operational internet satellites.

No injuries were reported, but the blast appears to have caused significant damage to Blue Origin's launch infrastructure. The company called the incident an "anomaly," and founder Jeff Bezos later described it as a "very rough day."

The explosion could complicate Amazon's satellite internet ambitions. The company is building a constellation of thousands of satellites to compete with SpaceX's Starlink and is counting on Blue Origin's New Glenn rocket to get them into orbit.

Elon Musk's SpaceX controls the majority of the world's rocket launch capacity, which has helped Starlink leap far ahead in providing internet satellite services. Blue Origin, a side project started by Amazon founder Bezos more than 25 years ago, has struggled to match these capabilities.

If Blue Origin's New Glenn rocket operation is sidelined for months, that could slow Amazon's launch schedule at a critical time, giving Starlink more time to extend its lead. About 30% of Amazon's satellites were slated to be deployed via New Glenn rockets under existing launch contracts, according to an Amazon spokesperson.

In an email to Amazon employees, Rajeev Badyal, the VP overseeing Amazon's Leo satellite program, cautioned that it was too early to speculate about the cause of the Blue Origin explosion or its potential effects, adding that such challenges are an expected part of spaceflight.

"I've been in this business for a long time and it's worth saying: Spaceflight is hard, and setbacks happen," Badyal wrote. Business Insider obtained a copy of his memo.

Badyal sought to reassure employees that Amazon's satellites were not destroyed in the explosion. He said the satellites "were not on the vehicle" and remained secure at the company's processing facility at Kennedy Space Center.

He also stressed that Amazon's broader launch strategy remains intact. The company has contracted with multiple providers, including United Launch Alliance and ArianeSpace, and Badyal said the team's focus on upcoming launches won't change.

"New Glenn is just one vehicle in our lineup," he wrote. "Our mission hasn't changed, our commitment to our customers and delivering service hasn't changed."

An Amazon spokesperson told Business Insider that the company's initial service rollout plans remain unchanged and that testing of the Leo network continues to expand.

Amazon has secured more than 100 launches for the Leo satellite internet program, with New Glenn accounting for less than a quarter of those missions, the spokesperson added.
