We know how to wow
There’s been a lot of SLS progress lately, so this edition includes two “wow” images:
Technicians with NASA’s Exploration Ground Systems moves the launch vehicle stage adapter (LVSA) for the SLS rocket to the Vehicle Assembly Building (VAB) at Kennedy Space Center July 30 for processing. The LVSA connects the SLS core stage to the rocket’s upper stage and will remain in the VAB until it’s time for stacking on the mobile launcher ahead of the Artemis I launch. 
Engineers at Marshall Space Flight Center completed the SLS rocket’s structural testing campaign for Artemis lunar missions by testing the liquid oxygen structural test article to find its point of failure. The test applied millions of pounds of force to the tank, simulating the stresses that the tank will undergo during flight.
