NASA just swapped a 10-year-old Artemis II engine with one nearly twice its age

Quick Summary:

One of the engines on NASA's next Space Launch System rocket requires repairs.

Teams began integrating the replacement engine with the rocket last Friday and are in the process of firmly securing it in the Engine 4 position on the core stage, the NASA spokesperson said.

In its place, technicians installed another RS-25 engine from NASA's inventory to the bottom of the rocket's core stage, which is standing vertical on its mobile launch platform inside the cavernous Vehicle Assembly Building at Kennedy.
