The Space Launch System (SLS) is NASA’s next advanced launch vehicle. Upon the completion of the project, it will be counted as the world’s most powerful rocket and will be used in together with the Orion Spacecraft in transporting up to four astronauts into deep space.

The new SLS is being built to bring humans on the first deep-space missions in more than 45 years, including an asteroid, or planet like Mars, Saturn, and Jupiter. NASA is continuously conducting a number of tests to finish developing the SLS.

The initial test on the engines of 2017 took place on the A-1 Test Stand at Stennis Space Centre near Bay St Louis, Mississippi which happened late last month. The recent test is the firing of one of the four RS-25 engines that will eventually be used to help clear Earth's atmosphere.

One RS-25 engine produces 512,000 pounds of thrust, which when four are attached to SLS it will produce over two million pounds of thrust. The Four RS-25 engines, coupled with a pair of rocket boosters will power NASA’s Orion rocket at launch.

NASA recently released a breathtaking footage of a moment showing a rocket engine exploding into life with the smoke and fire engine test through the use of multiple 360-degree cameras. The rocket-firing test took 6 minutes and 20 seconds to finish.

Last month, NASA made a study to assess the feasibility of adding a crew to Exploration Mission-1, which combines SLS and Orion. The purpose of the study is to find out if it's possible to accelerate adding a crewed flight to the new rocket-spacecraft combo and heading off into deep space. The mission will last 22 days and will test system readiness for future crewed operations.

On November 2018, the Space Launch System rocket will launch from a newly refurbished Kennedy Space Centre.
