Hey Space Placers!
Want to experience sheer power?
Tune in to NASA's test of its' J2X engine that will power the upper stage of the Space Launch System (SLS) that is being developed by NASA to send humans and cargo into space. The J2X is an upgraded version of the J2 rocket engine used in the S-II and S IVB stages of the Saturn V moon rocket.
Watch your ears if you have big speakers!
