Atlas V Booster Temperature Glitch Delays Amazon's Second Project Kuiper Launch

A high-temperature purge concern has postponed the second launch of 27 satellites, heightening the challenge of meeting the FCC’s July 2026 deployment deadline.

Overview

  • The second ULA Atlas V launch for Project Kuiper was postponed after engineers detected elevated purge temperatures in the booster’s first stage.
  • The Ka-02 mission would have placed 27 satellites into orbit, doubling Amazon’s network to 54 spacecraft ahead of the FCC’s mid-2026 milestone.
  • Amazon and ULA are assessing the anomaly before rescheduling liftoff to stay on track for the FCC requirement to have half of the 3,200-satellite constellation operational by July 2026.
  • ULA plans to ramp up launch cadence with its Vulcan rocket, which can carry 45 Kuiper satellites, alongside flights on Atlas V and rockets from Arianespace, Blue Origin and SpaceX.
  • Amazon’s $120 million processing facility at Kennedy Space Center accelerates final satellite prep, and ULA is targeting two launches per month from the Florida Space Coast.
