NASA tests 'megarocket' engine that will blast man to Mars

NASA's Exploration Mission-1 has stepped closer to reality, as the space agency completed the second flight controller tests for the engines that will power its'megarocket.' Engineers conducted a 500-second test on the component said to be the'brain' of the RS-25 engines – the four engines that will simultaneously provide 2 million pounds of thrust for the Space Launch System (SLS). NASA previously tested the first flight controller in March ahead of installation in one of the EM-1 engines, and once they've reviewed the new data, the second controller will be installed.
