Watch live: Blue Origin reusing New Glenn rocket stage for 1st time on April 19 launch

Key Points:

• Blue Origin's New Glenn rocket is set for its third launch on April 19, marking the first flight using a previously flown first-stage booster core, though with new engines installed.
• The NG-3 mission will deliver BlueBird 7, a large direct-to-cellphone internet satellite from AST SpaceMobile, to low Earth orbit, continuing the deployment of its internet constellation.
• New Glenn's first stage, powered by seven BE-4 methalox engines, aims to demonstrate full reusability by landing on the droneship "Jacklyn," a critical milestone for Blue Origin to compete with SpaceX's reusable rockets.
• The rocket's performance is pivotal for Blue Origin's future, including launching the Blue Moon lunar lander selected by NASA for the Artemis program, which has shifted focus to Earth orbit rendezvous before lunar landings.
• Blue Origin refurbished the NG-2 booster for this flight, replacing all seven engines and upgrading thermal protection, with plans to reuse these engines on future missions to achieve the rocket's goal of 25 flights per first-stage booster.
