"In the Orbiter Processing Facility, Columbia's engine no. 2 is seen at left after its removal from the orbiter. After small cracks were discovered on the LH2 Main Propulsion System (MPS) flow liners in two other orbiters, program managers decided to move forward with inspections on Columbia before clearing it for flight on STS-107. The heat shields were removed, and after removing the three main engines, inspections of the flow liners will follow. The July 19 launch of Columbia on STS-107 has been delayed a few weeks."

"NASA achieved a major milestone April 3 for production of new RS-25 engines to help power its Artemis campaign to the Moon and beyond with completion of a critical engine certification test series at NASA’s Stennis Space Center near Bay St. Louis, Mississippi.

The 12-test series represents a key step for lead engines contractor Aerojet Rocketdyne, an L3Harris Technologies company, to build new RS-25 engines, using modern processes and manufacturing techniques, for NASA’s SLS (Space Launch System) rockets that will power future lunar missions, beginning with Artemis V."

Space Shuttle Main Engine Lifted onto Test Stand A-1

"Space Shuttle Main Engine or SSME, weighing 6339 pounds, is lifted onto Test Stand A-1 at the National Space Technology Laboratories, marking the beginning of a new test phase. The huge stand is 238 feet tall -- the equivalent of a 16-story building. Following completion of facility activation and engine checkout by the NSTL team, the test program commenced May 19, 1975."
