    NASA Chooses Falcon Heavy Over SLS to Launch Europa Clipper, Saving About $2 Billion

    The bureaucracy of government control is slowly fading away in space exploration, at least in the US.* A series of delays, cost overruns, and imposed requirements have finally started taking its toll on the Space Launch System (SLS), the next generation NASA rocket system.* Now, the space agency has finally conceded a point to the …

    Isn't the SLS supposed to eventually take humans to the moon and beyond? Is the November 21st launch in peril?

    It seems torsion loads are a big factor. These are, I guess, not normal twisting loads around the axis of travel, but resultant loads on the payload from a bumpy ride. The rocket engines have a variation in thrust that would be the time derivative of acceleration, called jerk. If the payload is cantilevered by its support structure, that jerk becomes a torque because of the payload inertia and torsional inertia. It is sobering to read that redesigning the support structure is measured in Billions. At least that is my guess from limited information. Having a lot of smaller rocket engines would greatly reduce that jerk compared to say, solid boosters.

    When we realize that patterns don't exist in the universe, they are a template that we hold to the universe to make sense of it, it all makes a lot more sense.
