With both 40 satellite class rockets on the Western range grounded, Amazon has one Atlas V left for Leo and NASA is openly weighing Vulcan and Falcon Heavy as Artemis III backups.
The same Florida pad explosion that took Blue Origin's New Glenn offline is now rippling through the rest of the U.S. launch schedule, leaving NASA weighing fallback options for Artemis III and Amazon leaning on its last remaining Atlas V to keep the Leo broadband constellation moving.
Per the latest Rocket Report from Ars Technica (Rocket Report 8.45), New Glenn's loss at Launch Complex 36 roughly two weeks ago has removed one of only two rockets on the Western range with 40-satellite-class LEO capacity. The other, ULA's Vulcan, is also off-ramps for the time being, and the Ars Technica piece on the Artemis III vehicle question puts Vulcan's status back into the launch-vehicle conversation NASA is now having in public.
The cascade runs through three civil and commercial programs at once.
For Amazon, the FCC this week waived the July 2026 deadline that would have required deployment of half of the planned Leo constellation, with the full-constellation milestone now set for July 2029. The bottleneck is launch, not satellites: both New Glenn and Vulcan are down, and only a limited Atlas V inventory remains for Amazon, with satellites to be delivered from Cape Canaveral in the coming weeks.
For NASA, Artemis III's Blue Moon Mk2 test article was planned to fly on New Glenn, with Administrator Jared Isaacman putting the date no earlier than summer 2027. The agency is now openly running a "dual path" with Blue Origin and New Glenn on the prime track while it studies Vulcan and Falcon Heavy as backups. Payload fairing size is the main constraint, according to NASA Artemis program manager Jeremy Parsons. Blue Origin's leadership, including CEO Dave Limp and Jeff Bezos, has told NASA the company is "all in," and a second New Glenn pad is roughly a year into development with a 9x4-class capacity target, but neither pad was carrying a payload when New Glenn was lost.
The Blue Moon test article itself is built to bridge Mk1 and Mk2, sharing the same avionics, flight software, and crew module as the production lander, but using storable propellants and RCS instead of BE-7 cryogenics. That gives NASA a chance to demonstrate Earth-orbit rendezvous before committing to an uncrewed lunar demo. Mission planners are working to a -33 degree inclination in a circular orbit below 250 nautical miles, likely in the 230s, and the agency treats those numbers as the current target rather than the final figure.
Inside the same edition of Rocket Report, two threads point at how the gap might start to close. Stoke Space's Nova is working through a proto-qualification test campaign, and Isar Aerospace closed a €270 million Series D this week to fund serial production. Neither rocket fills the 40-sat-class slot that New Glenn and Vulcan occupy, and the Isar release did not name a new launch date, but both are signals that medium- and small-lift capacity is being capitalized for the moment the heavy end of the market has to catch up.
Meanwhile, SpaceX is set to launch its IPO on Friday, per the same Rocket Report digest. The timing is what matters: the public market is opening on the only U.S. heavy-lift vehicle still flying.
Three launches on the calendar over the next four days underline the asymmetry. H3 is flying an H3-30 test from Tanegashima at 00:53 UTC on June 12. A Falcon 9 is carrying Starlink 10-54 from Cape Canaveral at 12:27 UTC on June 13. Kinetica 1 is set for an unknown payload at 03:40 UTC on June 15 from Jiuquan. None of them is the rocket that Amazon or NASA needs back.
