United Launch Alliance announces the arrival of our Atlas V rocket at its Cape Canaveral pad to launch Amazon Leo 5, currently planned for Sunday at 3:53 a.m. EDT (0753 UTC). ULA will deliver 29 satellites into orbit for this fifth Amazon Leo mission, marking the largest and heaviest payload ever for the venerable rocket. Previous launches last year carried 27 spacecraft each. The increase is a result of detailed work between ULA and Amazon, and is made possible by an extensive engineering and safety analysis that capitalized on the additional performance margin, adding a fourth level to the previous three-tier dispenser configuration for Atlas V.
