The United Launch Alliance liftoff planned for Monday with dozens of new satellites to join Amazon's "Project Kuiper" mission was delayed due to engineering issues.

Project Kuiper finally began full-scale deployment of its low Earth orbit satellite network on April 28 at 1901 EDT (2301 UTC). A ULA Atlas V rocket lifted off from Space Launch Complex-41 at Cape Canaveral Space Force Station and deployed the first batch of 27 satellites into space at an altitude of 450 km (280 miles).
