Blue Origin still does not know why New Glenn exploded but plans to fly again this year

TL;DR

Blue Origin still does not know why New Glenn exploded in May, with early analysis pointing to the aft section of the first stage.

Blue Origin still does not know why its New Glenn rocket exploded last month, CEO Dave Limp said in a blog post on Tuesday. Early analysis points to the aft section of the first stage, according to Limp, who said the company is pulling on “extensive data from multiple camera angles and sensors” to identify the root cause. The explosion on May 28 destroyed the rocket and severely damaged Blue Origin’s only New Glenn launch pad at Cape Canaveral, Florida.

The rocket was preparing for its fourth flight when it detonated during a prelaunch engine test. Nobody was injured. New Glenn had flown three times since its debut in January 2025, reaching orbit on its first attempt but losing payloads on two of its three missions.

Limp praised employees for making quick progress on rebuilding the launch site. The company lost a lightning tower and the transporter-erector, the large piece of equipment that moved New Glenn to the pad and stood it upright. Nearby buildings were also damaged in the blast.

But Limp said the company “caught a lot of breaks, too, and intend to make the most of them.” The on-site water tower, gas tanks, and rocket integration facility are all in good shape, sparing Blue Origin from having to replace components with long manufacturing lead times.

In the most significant operational change, Blue Origin is abandoning the transporter-erector approach entirely. The company will instead use a massive crane to stand New Glenn upright on the pad before flights. Limp had previously pledged to fly again before the end of 2026, and he said the crane approach would not only allow a faster return to flight but also increase the rocket’s launch cadence going forward.

The stakes are high because Blue Origin has become central to NASA’s plan to return astronauts to the moon before President Trump leaves office. New Glenn is the designated launcher for the Blue Moon lander, which is meant to carry crews to the lunar surface for the Artemis programme. NASA is targeting 2028 for the first crewed landing since Apollo 17 in 1972, and every month of delay at Cape Canaveral compresses that schedule.

Blue Origin was planning as many as 12 launches this year before the May explosion, according to TechCrunch. Amazon’s satellite internet service, Amazon Leo, also depends on New Glenn to deploy hundreds of satellites against a looming FCC deadline. The company has contracted Blue Origin for 12 flights to build out the constellation, and the pad destruction has frozen that pipeline.

Identifying the root cause is the prerequisite for everything else. Blue Origin cannot return to flight, resume its NASA and Amazon manifests, or rebuild investor confidence until it knows what went wrong in the aft section of that first stage and can prove it has been fixed. Limp’s tone was optimistic, but a month after the explosion the company is still working on the first step.
