@RapidRick The engines are in a launch/upright position in the test stand. The @NASA_SLS RS-25 engines do not go truly horizontal during ascent, but we do have the ability to gimbal the engines on "the way up" to achieve directional positioning and ensure we hit our mark in deep space! https://t.co/qgOPZJTWiI — PolitiTweet.org
