Primary source: SpacePolicyOnline: Blue Origin's New Glenn rocket explodes during pre-launch test (May 28, 2026)

On the evening of May 28, 2026, Blue Origin’s New Glenn rocket exploded during a static-fire test at Cape Canaveral, SpacePolicyOnline reported. The rocket was being prepared to carry 48 Amazon Leo satellites the following week, and the satellites weren’t on it.

What happened

A static fire runs a rocket’s engines while it’s held down on the pad, a routine check before launch. SpacePolicyOnline quoted Blue Origin: “We experienced an anomaly during today’s hotfire test.” Its report set the scene: “The company was conducting a static fire test in advance of the planned launch of 48 Amazon Leo satellites next week.”

That launch would have been Amazon’s first on New Glenn. Losing the rocket meant losing the date as well.

What New Glenn means to Amazon Leo

• The biggest batches. Amazon said on Mar 23 that early New Glenn missions will carry 48 satellites each in the rocket’s 7-meter-wide fairing. Its first Vulcan missions carry 40, and recent Ariane 6 and Atlas V flights carried 29 to 36.
• A large share of future launches. The same post puts Amazon’s firm New Glenn bookings at 24 launches.
• A plan that counted on it. Amazon’s goal of more than 20 missions in its second year of deployment included the first New Glenn flight. Our post on that plan has the tally so far.

What’s known since

• No new date. As of Nov 3, 2026, no new date for Amazon’s first New Glenn mission had been found from Amazon or in press reports.
• Not in the near-term list. In an interview reported by Broadband Breakfast on Oct 9, Amazon Leo vice president Chris Weber listed the launches expected for the rest of 2026 as a Vulcan, then an Ariane 6, then more Vulcans. New Glenn wasn’t named.
• No Leo launch since Jul 2. Amazon’s next launch with an announced date is LV-01 on a Vulcan, targeted for Nov 13, 2026, pending range approval.

The explosion is one of three reasons no Leo satellite has launched since early July, alongside the end of Atlas V and Vulcan’s pause. The launch-pause post covers all three together, and our explainer on Leo’s rockets takes each rocket in turn.

Why it matters at home

Coverage and capacity grow with launches, and New Glenn was meant to carry Amazon’s largest loads. Until it flies for Leo, the pace rests on Vulcan and Ariane 6, which carry 40 and 36 satellites a flight. The explosion shrank the steps: without New Glenn, Amazon’s fleet grows in smaller batches, and how quickly it could serve more places once service starts depends on how soon that third rocket returns.
