Fifth controller tested at SSC

STENNIS SPACE CENTER, Miss. -- NASA engineers closed a summer of successful hot fire testing today for flight controllers on RS-25 engines that will help power the new Space Launch System (SLS) rocket being built to carry astronauts to deep-space destinations, including Mars. The space agency capped off summer testing with a 500-second hot fire of a fifth RS-25 engine flight controller unit on the A-1 Test Stand. The controller serves as the “brain” of the engine, communicating with SLS flight computers to ensure engines are performing at needed levels. NASA tested the first flight controller unit in March. The flight controller tests are critical preparation for upcoming SLS flights to deep space– the uncrewed Exploration Mission-1 (EM-1), which will serve as the first flight for the new rocket carrying an uncrewed Orion spacecraft, and EM-2, which will transport a crew of astronauts aboard Orion.
