NASA's Artemis I is on a mission to use their new space launch system (SLS). NASA will send its Orion spacecraft to the moon and it will be the first un-crewed integrated flight test. The thrust (force) of the SLS rocket at liftoff from Earth is 6.5 million pounds-force [Mlbf] with an acceleration of 15 meters per second squared [ms2]. As soon as the SLS rocket is launched, the total weight will reduce in stages with parts of the system detached (such as the rocket boosters and liquid hydrogen tank) until the Orion spacecraft reaches its intended orbit. It is estimated that the Orion spacecraft will have a weight of 40877 newtons [N] on the moon. Recall the acceleration due to gravity on the moon is 1.6 meters per second squared [ms2] and the acceleration due to gravity on Earth is 9.8 meters per second squared [ms2]. What is the total mass lost in pounds-mass [lbm] from liftoff on Earth to the landing on the moon? Express the answer in scientific notation (Z.Z x 10Z).
