Replay: weather scrubs launch of Atlas 5 with 27 Kuiper satellites for Amazon’s Starlink rival

Watch a replay of our live coverage as poor weather scrubbed the launch of an Atlas 5 rocket with the first 27 operational satellites for Amazon's Kuiper internet service on April 9, 2025.

Amazon’s satellite internet constellation, called Project Kuiper, is designed to rival others, like SpaceX’s Starlink and Eutelsat's OneWeb.

The mission features the most powerful Atlas 5 configuration, the 551, equipped with five solid rocket boosters from Northrop Grumman.
