NASA getting ready to test engines for Space Launch System rocket

Since the end of the Space Shuttle flights, NASA has been relying on help from Russia to launch men and women into space. The agency has been planning on replacement rockets to take humans into space and now engineers have taken a crucial step in preparing to test parts of NASA’s Space Launch System (SLS) rocket that will send humans to new destinations in the solar system. They installed on Thursday an RS-25 engine on the A-1 Test Stand at the agency’s Stennis Space Center near Bay St. Louis, Mississippi.
