NASA will soon fire up the most powerful rocket ever built

This liquid fuel engine is a beast.

NASA plans to ignite the most powerful rocket it's ever built on Jan. 17 according to a statement from the agency.

It will be the first firing of the Space Launch System (SLS), the long-awaited (and delayed) rocket ship that NASA plans to use for non-commercial human space flight. It's the centerpiece of NASA's Artemis program, a crewed mission to land, in language NASA frequently uses, "the first woman and next man" on the moon.

However, during this first ignition, only the liquid fuel engines at the core of the rocket will be tested, without the solid fuel boosters that will one day help carry SLS into orbit.

When the SLS core test-fires, it will become the most powerful rocket ever ignited on Earth.
