ULA faces further delays for Vulcan Centaur rocket launch.

United Launch Alliance (ULA) has delayed the debut launch of its new Vulcan Centaur rocket due to an investigation into an incident that occurred on March 29. The rocket's upper stage will be shipped back to its factory in Alabama for minor reinforcement before flight. The rocket's first stage is healthy and ready to support the first launch, which will send the private Peregrine lander towards the moon, two test satellites for Amazon's Project Kuiper internet megaconstellation, and a payload for Celestis. There is no new timeline for the mission yet, but ULA's CEO will provide an update in the next few weeks.
